The atomic number tells you the number of protons in an atom. This value never changes because the number of protons in the nucleus always remains constant. The mass number tells you the number of protons and neutrons (or nucleons) together: protons + neutrons = mass number. Since the number of neutrons in the nucleus varies, you can have different amounts of neutrons in the same type of atom. These varied types are called isotopes.

Y = +1-3 = -2
X = -5+7 = +2
D = √2^2-2^2 = 2√1+1 = 2√2 km
Use ideal gas equation, with T constant.
pV =nRT => pV / n = RT = constant
n = K* [units of particles]
pV / [units of particles] = constant
13 psi * 160 mL / 15 units = p * 150 mL / 10 units =>
=> p = [13psi*160mL/15units]*[10units/150mL] = 9.2 psi
Answer:
There would be tremendous earthquakes and tsunamis, followed by massive volcanism around the impact zone. The ozone layer would be destroyed. The oceans would turn acidic. The Sun would be blotted out, probably for decades.

Answer: Q= QH - QL
= W + QL - QL
= W
= 1 kj/8
