Is density a chemical property of matter?
No, density is a physical property of matter, not a chemical property. Density is a measure of how much mass is contained in a given volume of a substance. Chemical properties relate to the behavior of a substance in chemical reactions.
When 0.1 mol of calcium reacts with 880 g of water 2.24 L of hydrogen gas form at STP How would the amount of hydrogen produced change if the volume of water was decreased to 440 mL?
The amount of hydrogen produced will not change since the production of hydrogen gas in the reaction is determined by the number of moles of calcium reacting, which remains constant at 0.1 mol. The volume of water does not affect the amount of hydrogen gas produced as long as the stoichiometry of the reaction is maintained.
What are substances that change when the become involved in chemical reaction?
Rust is formed by the chemical reaction of oxygen to iron. This process is called oxidation and occurs when ever iron (or some other materials) are exposed to oxygen. The result makes a new substance: rust.
What volume of hydrogen chloride is produced by the reaction of 40 cm3 of chlorine with hydrogen?
Assuming that hydrogen, chlorine, and hydrogen chloride are all ideal gases and that the temperature and pressure are kept constant, the volume of gas depends only on the number of molecules of gas present. Also, at standard temperature and pressure, hydrogen and chlorine occur as diatomic molecules, and hydrogen chloride also occurs as diatomic molecules. The equation for the reaction is Cl2 + H2 -> 2 HCl. Therefore, the number of molecules of gas is the same before and after the reaction if both gases are present in the initial mixture that has a volume of 40 cm3. In that instance, the volume is the same before and after the reaction. However, the question seems to imply that hydrogen is supplied from an outside source. In that instance, there will be twice as many molecules after the reaction as before, so that the final volume will be 80 cm3.
Can you provide an example of residence time in a chemical reactor?
Residence time in a chemical reactor refers to the average time a substance stays inside the reactor. For example, if a chemical reaction takes 10 minutes to complete in a reactor with a volume of 100 liters, the residence time would be 10 minutes.
What is a eudiometer?
Eudiometer is an instrument which measure the change in the volume of gas (or mixture of gases) as a consequence of chemical or physical processes.
What is the use of a gas syringe in science?
A gas syringe is used to measure the volume of a gas produced in a chemical reaction. It allows for precise measurements of the volume of gas evolved in a reaction, which is important for determining reaction yields or understanding gas laws such as Boyle's Law and Charles's Law.
How do you measure the oxygen gas released in a lab?
You can measure the amount of oxygen gas released in a lab using various methods such as gas syringes, pressure sensors, or gas volume displacement techniques. These methods involve collecting and measuring the volume of oxygen gas produced during a chemical reaction or process.
How can one find the volume from moles in a chemical reaction?
To find the volume from moles in a chemical reaction, you can use the ideal gas law equation, which is PV nRT. Here, P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. By rearranging the equation to solve for V, you can calculate the volume of gas produced or consumed in the reaction.
Is volume conserved in a reaction between distilled water and ethanol?
Yes, volume is typically conserved in a reaction between distilled water and ethanol. The total volume of the reactants should equal the total volume of the products in a chemical reaction, assuming no gases are produced or consumed.
What volume of hydrogen gas is produced at stp as sulfuric acid reacts with 120 g of metallic calcium in a single replacement reaction?
The chemical reaction is:Ca + H2SO4 = CaSO4 + H2The volume of released hydrogen is 66,6 L.
Does volume not change when a chemical reaction takes place?
The volume is changed.
Is volume a physical property or chemical?
Volume is a physical property.
What is the use of gas measuring tube?
A gas measuring tube is a laboratory glassware used for collecting and measuring the volume of gases produced during a chemical reaction. It helps in determining the amount of gas produced and studying the stoichiometry of the reaction.
How to find moles from volume in a chemical reaction?
To find moles from volume in a chemical reaction, you can use the formula: moles volume (in liters) / molar volume (22.4 L/mol at standard conditions). Simply divide the volume of the gas by the molar volume to calculate the number of moles present in the reaction.
How many ml of gas would be produced if 2 spoons of baking soda reacted with 1.5 spoons of calcium chloride?
The reaction between baking soda and calcium chloride would produce carbon dioxide gas. The volume of gas produced would depend on the reaction conditions (temperature, pressure, etc.). To accurately determine the volume of gas produced, you would need to perform the reaction and measure the gas volume using appropriate techniques.
Is mass and volume conserved in a chemical change?
No. Mass must be conserved in a chemical changes according to the law of conservation of mass, which holds that the mass of the reactants and the mass of the products of a chemical reaction must be equal. However, there is no similar law about conserving volume and volume can change dramatically if a gas is produced.
