Answer: solid
Explanation: Chemical reactions are those which involve rearrangement of atoms.
Chemical changes are accompanied by following changes:
1) Absorption or release of heat
2) Change in color
3) Formation of gas bubbles
4) Formation of a solid product called as precipitate
Example of formation of precipitate or solid in chemical reaction:
The incorrect steps to do a complete stoichiometric calculation is option C which is Write the dimensional analysis because it does not entails the reactions between the reactants and the products.
<h3>What is stoichiometric calculation?</h3>
Stoichiometric calculations are calculations that are done in chemistry between the reactants and products which includes balancing of equations, conversation of moles in the reactants and products, evaluation of moles in the reactants and so on.
Therefore, The incorrect steps to do a complete stoichiometric calculation is option C which is Write the dimensional analysis because it does not entails the reactions between the reactants and the products.

Answer:
lichens,mosses,grasses,shrubs,trees
Explanation:
In order to answer this question, we are going to look at the molar ratio between H2O and H2, we can see that by analyzing the numbers in front of the compounds, and we can see that the molar ratio is 2:2, this means that for every 2 moles of water decomposing, we will end up with 2 moles of H2 being produced, therefore the same amount of moles for H2O will be the same amount of moles of H2, which means that if we have 100 moles of H2O being decomposed, we will also have 100 moles of H2 being produced.
