Let's say that you were given the following
problem:
a gas that exerts a pressure of 151 mm hg in a
container with a volume of _ l will exert a
pressure of 166 mm hg when transferred to a
container with a volume of 0.532 l.
answer
let's begin by assigning our variables. let's say
that p1 = 151 mm hg. what is v2?
a. 166 mm hgb. 0.532 l
c. unknown

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

the answer would be a

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
