Chemical properties observed only when a substance undergoes a chemical change a true bfalse?
True. Chemical properties are characteristics that can only be observed when a substance undergoes a chemical change, such as reactivity with other substances or the ability to undergo a chemical reaction.
What are the importance of true density of soil?
The true density of soil is important for calculating porosity and void ratio, which affect the soil's ability to hold water and nutrients. It is also used to determine soil texture and compaction levels, which can impact plant growth and stability for construction projects. Additionally, true density can provide insights into soil composition and help assess soil quality for various applications.
Why interstitial hydrides are not true chemical compounds?
Interstitial hydrides are not true chemical compounds because they do not have a fixed stoichiometry and exhibit variable composition. They form due to the absorption of hydrogen by certain metals, with the hydrogen atoms occupying spaces between metal atoms in the crystal lattice rather than forming distinct chemical bonds. This results in non-stoichiometric behavior and a lack of well-defined chemical properties characteristic of traditional chemical compounds.
A pail of sand and soil is a mixture true or false?
True. A pail containing both sand and soil would be considered a mixture as it is a combination of two or more substances physically combined but not chemically bonded.
Scientists classify types of soil based partly on a regions climate true or false?
True. Soil types can be influenced by a region's climate, as factors such as temperature, precipitation, and vegetation play a role in determining the characteristics of soil in that area.
What happens when you add bromide and zinc chloride solution?
It is not a true chemical reaction.
What type of homogenous mixture is considered a solution?
A solution is a true homogeneous mixture: only one phase.
Is alkali metals a group 1 elements?
No that is group 2. Group 1 is called Alkali metals.
True or False The chemical reactivity of metals tends to increase from left to right across the periodic table?
False. The most chemically reactive metals are in the two leftmost columns.
Is true Metals are not good conductors of electricity. An electrolyte solution conducts electricity. Wood is a good conductor of electricity. Nonmetals are good conductors of electricity.?
1. Metals are good conductors of electricity.2.An electrolyte solution conducts electricity.3. Wood and nonmetals are not good conductors of electricity.
What is it true or false. Corrosion is a physical property of metals.?
False. Corrosion is a chemical property. When a metal corrodes, it reacts with its environment to produce oxides, hydroxides, and other types of corrosion.
Is A chemical reaction occurs when a solution is formed true or false?
False. A chemical reaction does not occur simply by forming a solution. A chemical reaction involves the breaking and forming of chemical bonds between atoms, resulting in the conversion of reactants into products.
Is it true that the solution is a mixture composed of two or more substance that are physically blended but not chemically combined?
Yes, that statement is true. A solution is a homogeneous mixture where two or more substances are physically blended together but do not undergo a chemical reaction to form new compounds. The components in a solution can be separated by physical means like filtration or evaporation.
Is it true that transition metals are less reactive than the metals in group one and two of the periodic table?
True
Protecting soil from erosion and pollution is called soil conservation true or false?
True
Is it true chemical properties can be used to remove lead from a solution of lead and other materials?
Yes, it is true. Chemical properties such as solubility, precipitation, or complexation can be utilized to remove lead from a solution. For instance, adding a chelating agent that forms complexes with lead can help remove it from the solution. Similarly, adding a precipitant that reacts with lead ions to form insoluble lead compounds can also facilitate its removal.
If metals loose electrons to non metals are metals now anions?
No, it is not true. When metals loose electrons they become cations.
