Answer:
B. A rate constant
Explanation:
The mathematical expression of rate law is given below,
Rate = K[A]m[B]n
This rate law show the relationship between the rate of chemical reaction and concentration of reactants.
In given equation [A] and [B] are molar concentration of reactants while K represent rate constant.
The value of K is specific for particular reaction at particular temperature,
m and n are represent exponents and determine experimentally. The value of K is not depend upon the concentrations of reactant but depend upon the surface area and temperature
Answer:
There could be a few answers for this question, but my answer would be two different plants. Maybe a bush on the ground fighting for the energy of the sun with a tall tree. Leaves collect the energy from the sun and convert it to energy usable for the plant. a bush on the ground would be fighting for the sunlight with a tall tree.
Answer:
The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in
the products
Explanation:
For an equation to termed balance, the number of atoms of elements in the reactants must be equal to the number of atoms of the same element in the product.
The law of conservation of mass states that matter can neither be created nor destroyed during a chemical reaction but changes from one form to another. An unbalanced equation simply means that matter have been created or destroyed. This implies that balancing equation supports the laws of conservation of mass

The pH of the buffer that consists of 0.55 M HNO₂ is 3.3, which is acidic.
<h3>
What is the common name for 0.55 M HNO₂?</h3>
The common name for 0.55 M HNO₂ is Nitrous acid. Only in solution, the gas phase, and in the form of nitrite salts is nitrous acid, a weak and monoprotic acid, known to science. Amines are converted into diazonium salts using nitrous acid. To produce azo colors, azo coupling processes use the resultant diazonium salts as reagents. A nitrogen oxoacid is a nitrous acid. It is a nitrite's conjugate acid. To treat cyanide poisoning, sodium thiosulfate is combined intravenously with nitrous acid (as sodium nitrite).
