Answer:
2
Explanation:
Since you are balancing the equation you need to have equal amounts of each element on each side. Right now there is 2n and 2o on one side, and on the other 2n and 1o. Although the number of n's on each side is equal the number of o's are not. First I balance the number of oxygen's on each below, but doing that made the number of nitrogen's unbalanced. So then I balanced the nitrogens in step 2.
__N2+ __O2 = __N2O
1. __N2+ __O2 = 2 N20
2. 2 N2 + 1 O2 = 2 N2O
Answer:
B
Explanation:
The letter in this energy profile diagram of an exothermic change that signifies energy is B;
- An exothermic reaction is one in which heat is liberated to the surroundings.
- The surrounding becomes hotter at the end of the change.
- B is the enthalpy change of the reaction
- A is the activation energy
- C is the reactant
- D is the product

When the phosphate groups of the single nucleotides combine to form the backbone of the nucleic acid, energy is released. This energy is used for polymerization.
Answer:
Explanation:
Hello!
In this case, considering the Avogadro's number, which relates the number of particles and one mole, we can infer that 1 mole of any element contains 6.022x10²³ atoms as shown below:
Thus, we compute the number of atoms in 0.035 moles as shown below:
