The answer is true, catalysts increase rates by lowering the activation energy of a reaction. Catalysts lower the reaction energy and so the reaction occurs faster. Enzymes perform the role of biological catalysts. Most metabolic pathways of the body are controlled by enzymes. Enzymes by classification are proteins. <span />

What are the missing coefficients for the skeleton equation below?
Kruka [31]

Answer:

4, 3 , 2 and 6

Explanation:

The reaction equation is given as;

       NH₃  +  O₂   →    N₂   +   H₂O

Now, we need to balance the reaction equation;

     NH₃  +  O₂   →    N₂   +   H₂O

put the numbers a,b,c and d;

    aNH₃  +  bO₂   →    cN₂   +   dH₂O  

We need to balance the equation algebraically, ;

  Conserving N;

      a = 2c

   Conserving H;

      3a  = 2d

   Conserving O;

      2b  = d

Now, let c = 1, a = 2, d  = 3 and b  = \frac{3}{2}  

  multiply through by 2;

            a  = 4, b = 3, c  = 2 and d  = 6

Insert the parameters:

                  4NH₃  +  3O₂   →    2N₂   +   6H₂O

Verizon [17]
The conjugate acid of ch3nh2 is ch3nh3+<span>.
</span>For example methylamine in water chemical reaction: 
CH₃NH₂(aq)+ H₂O(l) ⇌ CH₃NH₃⁺(aq) + OH⁻(aq).
According to  Bronsted-Lowry theory acid are donor of protons and bases are acceptors of protons (the hydrogen cation or H⁺). Methylamine (CH₃NH₂) is Bronsted base and it can accept proton and become conjugate acid (CH₃NH₃⁺).
