Answer:
Atoms of the reactant(s) must equal the atoms of the product(s).
Explanation:
According to the Law of Conservation, all atoms of the reactant(s) must equal the atoms of the product(s).
As a result, we need to balance chemical equations. We do this by adding in coefficients to the reactants and/or products. The compound(s) itself/themselves DOES NOT CHANGE.
The question is incomplete, here is the complete question:
A chemist measures the amount of nitrogen gas produced during an experiment. She finds that of 282. g of nitrogen gas is produced. Calculate the number of moles of nitrogen gas produced. Be sure your answer has the correct number of significant digits.
<u>Answer:</u> The number of moles of nitrogen gas produced are 10.07 moles
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
We are given:
Given mass of nitrogen gas = 282 g
Molar mass of nitrogen gas = 28 g/mol
Putting values in above equation, we get:
Hence, the number of moles of nitrogen gas produced are 10.07 moles
Ammonium iodide, or NH₄I, is a salt. Since all salts are strong electrolytes, when ammonium iodide is dissolved in water, it would dissociate into ammonium ions and iodide ions. Hence, the major species present would be: <em>NH₄⁺ and I⁻ ions</em>.
A simple chemical reaction with a single substrate shows a linear relationship between the rate of formation of product and the concentration of substrate, as shown below: ... The relationship between rate of reaction and concentration of substrate depends on the affinity of the enzyme for its substrate.
