Answer:
Combination or synthesis reaction
Explanation:
The reaction is a combination or synthesis reaction.
Let us write the reaction equation:
CO + H₂O → H₂CO₃
A combination or synthesis reaction is one in which a single product forms from two or more reactants. The formation of a compounds from the union of their constituent elements falls into this category of reaction.
- The combination of carbon monoxide and water to give hydrogen carbonate is one of such reaction.
Li is the highest ionization energy
Answer:
Explanation:
A marble is not a very large object, so a smaller graduated cylinder is a better choice. A 100 milliliter graduated cylinder is not needed to measure the volume of a small marble, so a 25 milliliter graduated cylinder is the best option.

- The mineral’s physical properties are used in identifying minerals and are determined by its chemical composition and crystal structure.
- <u>Streak</u> is the color of the mineral in powdered form and since it is a more accurate illustration of the mineral’s color, its is a more reliable property of minerals than color for identification.
- <u>Hardness</u> is one of the better properties of minerals to use for identifying a mineral. Hardness is a measure of the mineral’s resistance to scratching.
- <u>Density</u> may be used to identify minerals. It is used to describe the amount of matter in a certain amount of space. Substances that have more matter packed into a given space have higher densities.
