Answer:

The stoichiometric coefficients.

Explanation:

Hello,

Chemical reactions are widely generalized by the following chemical equation:

aA+bB-->cC+dD

Capitalized letters are referred to both the reacting and produced species during the chemical reaction meanwhile the lowered case letters are referred to the stoichiometric coefficients which balance the chemical reaction. Balancing means that the number of atoms in the reagents must be equal to the number of atoms in the products, this is exemplified via the following balanced chemical reaction:

2HCl+Ca(OH)_2-->CaCl_2+2H_2O

The coefficient 2 in the hydrochloric acid is set due to the produced calcium chloride which has two chlorine atoms in order to equal them.

Best regards.

Answer: Stochiometric coefficients

Explanation: The chemical equations must be balanced to follow the law of conservation of mass which says that the mass of products must be same as the mass of reactants.

CH_4+O_2\rightarrow CO_2+H_2O

This is a skeletal equation  and needs to be balanced by adjusting the stochiometric coefficients. In order to keep the mass same, the number of atoms must be same on both sides.  

CH_4+2O_2\rightarrow CO_2+2H_2O

Why is the formation of water a synthesis reaction?
lisabon 2012 [21]

Explanation:

A synthesis reaction: It is defined as a kind of reaction where one and more than one reactant attached and creates an individual product.

The formation of the water is an example of a synthesis reaction because here more than one reactants combine and create a single product (water). Water formation occurs when 2 hydrogens and an oxygen share electrons through covalent bonds.

2H + O ----> H2O.

. What is the first element on the periodic table?
melamori03 [73]

Answer:

The first element in the periodic table is hydrogen.

Explanation:

Hydrogen has an atomic number of one, making it the first element of the periodic table. The atomic number of an element is just the number of protons in the nucleus, so hydrogen has one proton. The neutrons and electrons do not affect the atomic number. After hydrogen with one proton comes helium with two, lithium with three, beryllium with four, and so on.
