Which liquids have little density?

User Avatar

Asked by Wiki User

The liquids that have low density include substances like alcohol, gasoline, and lighter fluid. These liquids have low mass compared to their volume, which results in their low density.

What are the chemical reaction for an old fruit salad?

User Avatar

Asked by Wiki User

An old fruit salad undergoes various chemical reactions as it decomposes. One common reaction is fermentation, where microorganisms break down sugars in the fruit to produce alcohol and carbon dioxide. Another reaction is oxidation, where enzymes in the fruit react with oxygen in the air, causing browning or discoloration. Additionally, there may be chemical reactions involving mold or other spoilage microorganisms present in the fruit.

What are the use of mixture?

User Avatar

Asked by Wiki User

Mixtures have a wide range of uses in daily life and various industries. For example, mixtures are commonly used in cooking and food preparation to combine ingredients and create flavorful dishes. In chemistry, mixtures are used to create solutions, blends, and alloys. Additionally, mixtures play a crucial role in pharmaceuticals, cosmetics, agriculture, and many other fields.

What atoms has the weakest attraction for electrons in a bond with a calcium Ca atom?

User Avatar

Asked by Wiki User

Atoms with weak electron attraction in a bond with calcium (Ca) include alkali metals such as lithium (Li), sodium (Na), and potassium (K). These atoms have only one valence electron, making it easier for them to lose or donate electrons rather than attract or share them. As a result, they tend to form ionic bonds with calcium, where calcium loses electrons and the alkali metal gains them.

Which chemical in the body may be responsible for the fatigue that many players face on their first day in the new city?

User Avatar

Asked by Wiki User

Adenosine is a chemical in the body that may contribute to fatigue. It accumulates in the brain throughout the day and can promote sleepiness. If players are experiencing fatigue on their first day in a new city, it could be due to disrupted sleep patterns, increased stress, or changes in daily routine, which could impact adenosine levels and lead to fatigue.

What is the Oxidizing agent used in the aeration process is?

User Avatar

Asked by Wiki User

The oxidizing agent commonly used in the aeration process is oxygen (O2). Oxygen is introduced into a liquid, such as water or wastewater, to promote the oxidation of organic and inorganic substances, thus facilitating the breakdown of pollutants and the improvement of water quality.

Is production of light chemical or physical property?

User Avatar

Asked by Wiki User

The production of light can be a physical or chemical property. Physical properties would include phenomena like luminescence or fluorescence, where certain materials are capable of emitting light without undergoing chemical reactions. Chemical properties would include processes like combustion or bioluminescence, where the production of light is a result of chemical reactions taking place.

Do Thiazide Diuretics decrease renal excretion of Phosphate?

User Avatar

Asked by MariyaTabassum

No, Thiazide Diuretics actually increase renal excretion of Phosphate. They inhibit the sodium-chloride symporter in the distal convoluted tubule of the kidney, leading to increased excretion of sodium, chloride, and also phosphate.

Are bubble forming in a soda an example of exothermic reaction?

User Avatar

Asked by Wiki User

No, the formation of bubbles in a soda is not an example of an exothermic reaction. It is actually a result of a physical process called carbonation, where carbon dioxide gas is dissolved in the liquid under pressure.

How do you check platinum?

User Avatar

Asked by Wiki User

To check if a metal item is made of platinum, you can start by looking for hallmarks or stamps on the item. Platinum jewelry is often marked with a "Pt" or "Plat" stamp. You can also conduct a magnet test, as platinum is not magnetic. Additionally, you can take the item to a professional jeweler or use a testing solution specifically designed to determine the metal content.

What gas is in regular air?

User Avatar

Asked by Wiki User

The gas in regular air is primarily nitrogen, which makes up about 78% of the atmospheric composition. Oxygen is the second most abundant gas in air, with a concentration of around 21%. Trace amounts of other gases such as argon, carbon dioxide, and helium are also present.

How much water is used for sugar crystals?

User Avatar

Asked by Wiki User

The amount of water used in making sugar crystals varies depending on the recipe and desired consistency. Typically, a ratio of 1 part water to 2 parts sugar is used. For example, if you use 1 cup of water, you would use 2 cups of sugar. However, it's important to note that the water is mostly evaporated during the crystallization process, so the final product is primarily sugar.

Should you get buckyballs or neocube?

User Avatar

Asked by Wiki User

The decision between Buckyballs and Neocube depends on your personal preferences. Buckyballs are magnetic balls that can be shaped and molded into various structures and objects. Neocube, on the other hand, is a specific brand of magnetic balls that is similar to Buckyballs. Both provide a similar experience, so choose based on your preference for brand or availability.

What are examples of determinism?

User Avatar

Asked by Wiki User

Well for a start define determinism Every action has a cause, a part of the causal chain so you have no choices, no free will. Every action is caused by something. You are not held responsible for any of your actions For example: You are brought uo in an abusive household and so you will go on to abuse your own family. You will not be held morally responsible for your actions because that is how you were raised, you did not choose to be that way. Those who believe on free will will argue that the person had e choice to be abusive to their own family, they could have chosen to seek help and deal with the problem but they chose not to, Another idea is that of genetics, Say alchoholism runs in the family, it is in your DNA you cannot be held responsbile for beong an alchoholic because it is a genetic predisoition. It is INHERITED and yiu cannot control or choose your genes. I hope this made sense!! If it doesnt then i will fail my philosophy exam (!) so i hope it does. Haha

What makes pH important quality of the solution?

User Avatar

Asked by Wiki User

pH is an important quality of a solution because it indicates its acidity or alkalinity. It affects the chemical reactions, solubility of substances, and the behavior of ions in the solution. Many biological processes, such as enzyme activity, are highly dependent on maintaining a specific pH range for optimal functioning. pH also plays a role in determining the suitability of a solution for various applications, such as in agriculture, medicine, and industrial processes.

Why hydrated salts look dry?

User Avatar

Asked by Wiki User

Hydrated salts appear dry because they have incorporated water molecules within their crystal lattice structure. This water is not easily visible on the surface of the salt, giving the appearance of dryness. However, if the hydrated salt is heated or exposed to low humidity conditions, the water molecules can be released, causing the salt to become visibly wet.

What compound is used for calico printing?

User Avatar

Asked by Wiki User

The compound traditionally used for calico printing is a type of synthetic dye called alizarin. Alizarin provides bright and vibrant colors that are suitable for printing on fabrics. However, modern calico printing may also involve the use of other synthetic dyes and pigments.

Which postulates of the kinetic molecular theory explain the observation that a sample of a gas with particles in rapid random motion does not cool down?

User Avatar

Asked by Wiki User

According to the kinetic molecular theory, gases consist of particles in constant random motion. Two postulates can explain why a sample of a gas does not cool down: First, the particles have a range of speeds, so while some may collide and transfer energy, others will collide and gain energy. Second, the average kinetic energy of the gas particles remains constant as long as the temperature is constant. Therefore, while collisions may occur and redistribute the energy, the overall average kinetic energy, and hence temperature, of the gas remains constant.

What mixture will thaw ice on a car and what is it made of?

User Avatar

Asked by Wiki User

A common mixture to thaw ice on a car is a solution of water and isopropyl alcohol. This mixture is made by combining equal parts of water and isopropyl alcohol. The alcohol helps to lower the freezing point of water, allowing it to melt ice more effectively.
