Answer:mass of reactants = mass of products

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

H_2+O_2\rightarrow 2H_2O

mass of hydrogen= 4 g

Mass of oxygen = 32 g

mass of water = 2times 18=36g

Thus mass or reactants =

Mass of hydrogen + mass of oxygen= 4+32= 36 g

Mass of product = mass of water = 36 g

Thus the total mass of reactants is equal to the total mass of products.

The correct answer is a mass of products = mass of reactants.  

In a chemical reaction, the law of conservation of mass states that the entire mass of reactants is equivalent to the entire mass of products. For example, the mass of sodium and the mass of chlorine, which reacts with the sodium is equivalent to the product sodium chloride's mass. As in the chemical reaction, the atoms are only rearranged, there must be an equal number of chlorine and sodium atoms in both the products and the reactants.

6CO2 + 6H20 → C,H120, + 602
tatyana61 [14]

Explanation:

The equation of the reaction is given as;

6CO2 + 6H2O → C6H12O6 + 6O2

How many molecules of CO2 are present?

6 moles

How many atoms of oxygen are present in the reactants?

(6 * 2) + (6 * 1 ) = 12 + 6 = 18

How many atoms of carbon are present in the products?

(6 * 1 ) = 6

How many total atoms are present in C6H12O6?

6 + 12 + 6 = 24 atoms

Is the equation above balanced or unbalanced?

This is a balanced equation since the number of atoms of the elements is the same in the reactant and products.

In acidic solution, the breakdown of sucrose into glucose and fructose has this rate law: Rate = k[H⁺][sucrose]. The initial rat
yKpoI14uk [10]

In an acidic solution, the rate change if Sucrose is changed to 2.5 M will be  Rate = k[H⁺][2.51M] as the initial rate of sucrose breakdown is measured in a solution that is 0.01 M H⁺.

<h3>What is the breakdown of sucrose?</h3>

Sucrose is a type of sugar that is made by adding fructose and glucose or the breakdown of fructose will be in the form of glucose and fructose always at different levels of concentration.

In the given acidic solution if the concentration of sucrose changes from 0.01 to 2.5 then both have to add to give the total rate of change in the given reaction and it will be 2.51 M.

Therefore, Rate = k[H⁺][2.51M] as the initial rate of sucrose breakdown is measured in a solution that is 0.01 M H⁺for an acidic solution, the rate change if Sucrose is changed to 2.5 M.

Hello! Those are called the isotopes of those elements!! They have more than just one form and each has it’s own AMU’s so the multiple numbers above different elements, represent the isotopes of those elements. Carbon is a good one just for one example.

Hope this helps you out! Questions please just ask! Thanks!
