Answer:

production of a gas

Explanation:

What makes the cake grow is the action caused by yeast. When added in the dough the yeast undergoes a chemical transformation releasing carbon dioxide, for example from the reaction between sodium bicarbonate and monoacid phosphate. It is the carbon dioxide that makes the cake grow, making the dough light and soft. This reaction is favored by heating, so the use of frozen ingredients in the preparation of the dough can harm the end result.

Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

when a reactive metal is added to water, bubbles or fizzing can be observed. Explain the appearance of the bubbles

MakcuM [25]

Answer:

This is because of the release of hydrogen gas in the reaction.

Explanation:

Metals react with water and produce a metal oxide and hydrogen gas. It also starts floating due to the bubbles of hydrogen gas sticking to its surface.

For eg:

2Mg. + 2H2O --------> 2MgOH + H2

Here,

Metal taken is magnesium(2Mg) which when reacts with water(2H2O) to form its oxide form (2MgOH) and hydrogen gas(H2) is released which comes outside water as bubbles.
