What is the word equation of calcium with hydrochloric acid?
One gram atomic mass of calcium reacts with two gram molecular masses of hydrochloric acid to form one gram formula mass of calcium chloride and one gram molecular mass of diatomic hydrogen gas.
Aluminum hydroxide reacts with nitric acid to form aluminum nitrate and water what mass of water can be formed by the reaction of 15.0 g of aluminum hydroxide with excess nitric acid?
10.4g
When a substance changes from a solid to a liquid its density normally decreases. What is happening to the substance's mass and volume to cause this decrease in density?
A decrease in density would indicate a reduction in mass relative to the volume. If the mass decreases but the volume remains the same or increases, then the density would decrease.
What is the mass of aluminium metal that reacts to give 1.00 g of iron?
The mass of aluminium is 0,48 g.
Why the appearance and mass of sodium changes when it reacts with oxygen?
it will burn up
Why is there a decrease in mass when calcium carbonate reacts with hydrochloric acid?
CO2 gas is formed, and as it is leaving the instrument in which this reaction is done in, the mass decreases.
What happens to total mass when an acid reacts with an alkali?
Total mass remains the same according to the law of conservation of mass.
What do you observe when calcium carbonate reacts with hydrochloric acid?
The loss of mass from the start as time goes on
A mass of 21.5 grams of calcium hydroxide reacts with an excess of phosphoric acid What mass of calcium phosphate could be recovered from solution?
31.6grams
What happens to the total mass when an acid reacts with an alkali?
The total mass will remain the same. The Law of Mass Conservation that matter cannot be created or destroyed. So, as long as the acid and the base react in a closed system (none of the products escape measurement) the mass will remain the same. The only way the total mass could seem less then the original mass would be because some of the water, that is always created in the reaction of an acid or base, has evaporated. Or in the case of Sodium bicarbonate (baking soda) carbon dioxide is released when it reacts with an acid, so unless it reacts in a closed system, that mass will escape measure.

Aluminum hydroxide reacts with nitric acid to form aluminum nitrate and water what mass of water can be formed by the reaction of 15.0 g of aluminum hydroxide with excess nitric acid?

Do you increase or decrease in mass?
you increase or decrease mass by taking the mass out
When a metal carbonate reacts with an acid carbon dioxide is always produced what factors might affect the volume of gas produced?
The mass of the carbonate used.
What are the signs of chemical change if you combine a steel to the solution?
This depends on the nature of solution; when the sample react with an acid the mass decrease and the solution become colored.
When acetic acid and sodium bicarbonate react why does total mass decrease?
Because CO2 is released during the experiment which accounts for some of the weight loss
Does the mass increase or decrease when anhydrous compounds decompose?
when anhydrous compounds decompose their mass will decrease
