The answer is C) Metamorphic
Answer: V= 44. 6 L
Explanation: use Boyle's Law
P1V1 = P2V2
Derive to find V2:
V2 = P1V1 / P2
= 937.57 Pa( 12.5 L ) / 262.52 Pa
= 44.6 L
Answer:
Rain washes mineral ions from the land int water.
Explanation:
The amount of rain is highest at the equator and lowest at the poles. Due to this heavy amount of rain at the equator areas minerals get washed from land to the water. The washed minerals when be in the watery medium the either dissolve or dissociate to different ions according to their nature. The dissolution or dissociation of minerals in the water releases various salts in the medium and it becomes salty because of their presence in higher amounts.
<span>The right answer is the option B. Close to 99 percent. The atmosphere is a mixture of gases: nitrogen, oxygen, CO2, H2O, argon, among others. Nitrogen is about 78% and oxygen is about 21%, so they two together constitute about 99 percent of the Earth's atmosphere.</span>
atomic number = protons.
protons+neutrons=atomic mass.
170 (mass) - 41 (proton/number) = 129
that should be ur answer. I hope this helps!
