Answer:
Overall reaction equation:
2NO (g) + O2(g) ---------> 2NO2(g)
Overall rate= k1 [NO]^2
Explanation:
Overall reaction equation:
2NO (g) + O2(g) ---------> 2NO2(g)
The overall reaction equation is obtained by adding the two equations. This now gives the actual overall equations when intermediates must have been cancelled out.
Since k1<<k2 which me as that the first step is much slower than the second step, then the first step is the rate determining step, being the slowest step in the non elementary reaction sequence.
Therefore overall rate;
Overall rate= k1 [NO]^2
1. The symbol for an isotope of lithium that has a mass of 6 and a charge of +1 is ⁶₃Li⁺
2. If the ratio of the neutron and proton in the nucleus of an atom increases, the nucleus becomes unstable.
3. Allie's hypothesis is correct because atoms B and C have the same atomic number but different neutron numbers, hence, they are isotopes.
4. Rana's hypothesis is wrong because the number of electrons is greater than the number of protons, hence atom C is a negative ion.
5. The symbols are wrong for the following reasons;
- MG is wrong because the symbol of atoms consists of first a capital letter, and then a small letter
- ca is wrong because the symbol of atoms consists of first a capital letter, and then a small letter
- nE is wrong because the symbol of atoms consists of first a capital letter, and then a small letter
<h3>What determines the charge on an atom of an element?</h3>
The charge on an atom of an element is determined by the number of protons and neutrons in the atom.
A neutral atom has an equal number of protons and electrons, a negative atom has more electro than protons, while a positive ion has more protons than electrons.
Isotopes of elements are atoms of the same element having the same number of protons but different numbers of neutrons.

Answer:
I'm not sure if this is true but in science class I learned that stress can cause a risk of diseases
Explanation:
the more months of stress you have, the higher the risk
Atoms<span> are made up of three particles: protons, neutrons and electrons. Protons and neutrons are heavier than electrons and reside in the center of the </span>atom, which is called the nucleus<span>. Electrons are extremely lightweight and exist in a cloud orbiting the </span>nucleus.
Mitosis makes new cells and replaces the cells that are old, lost or damaged
