We are given the rate law, so we can substitute the given values for the rate constant and the concentrations of the reactants to solve for the rate of reaction. Since rate = k [NH4+][NO2-]:
rate = (2.7 x 10^-4 / M-s)(0.050 M)(0.25 M) = 3.375 x 10^-6 M/s
Answer:
Igneous rocks must go through the sedimentary process to change into metamorphic rocks. Igneous rocks are chemically changed into metamorphic rocks because of high temperature and pressure. Metamorphic rocks are formed from melting igneous rocks. Metamorphic rocks and igneous rocks do not follow a rock cycle.

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 = 
multiply through by 2;
a = 4, b = 3, c = 2 and d = 6
Insert the parameters:
4NH₃ + 3O₂ → 2N₂ + 6H₂O
Gas is the most compressible because the atoms have more space in between. solids on the other hand, are the least compressible because their atoms are really closely packed.
