The chemical formula of water is written as H2O we can just use the ratio of the atoms since we are not given the reaction. Hydrogen is a diatomic substance so that it exists as H2. We calculate as follows:

0.253 mol H2O ( 1 mol H2 / 1 mol H2O ) = 0.253 H2 needed

Hope this answers the question. Have a nice day.

Which is the following is a decomposition reaction
lora16 [44]

The equation that is a decomposition reaction is

PbCO3(s) ---> PbO(s) + CO2(g)

That is option D.

<h3>Properties of a decomposition reaction</h3>

A chemical reaction is defined as the combination of substances called reactants to form a product. The various types of chemical reaction include:

  • synthesis reaction

  • combustion reaction

  • decomposition reaction

  • single or double replacement reaction

Decomposition reaction is that type of chemical reaction in which the reactant breaks down to form two or more products.

Therefore the heating of lead (II) carbonate is a decomposition reaction.

Kernels of corn are heated and become popcorn. Why is this a chemical change?
goldfiish [28.3K]

Answer:

When popcorn is popped, liquid inside the kernel is changed to steam. Pressure from the steam builds up inside the kernel. When the pressure reached a critical stage the kernel pops turning itself inside out. This is a physical change.

Ensure you write the states of the reactants and products.
slamgirl [31]
<h3>Answer:</h3>

Phosphoric acid reacts with magnesium hydroxide to produce magnesium phosphate and water via the following reaction:

2H3PO4 + 3Mg(OH)2 → Mg3(PO4)2 + 6H2O

(solid) (solid) (solid) (liquid)

<h3>Explaination:</h3>

This is a typical neutralization reaction of an acid with a base to form a salt and water. The reaction is exothermic, gives off heat,

ΔH < 0 , and may be balanced by adding balancing numbers in front, ie adding molecules, in order to ensure that the total number of atoms of each element is the same on the left and right hand sides of the equation.

Doing so we obtain :

2H3PO4 + 3Mg(OH)2 → Mg3(PO4)2 + 6H2O

(solid) (solid) (solid) (liquid)
