Answer:
Newer
Explanation:
older fossils and rocks are found in lower strata than younger fossils and rock layers because the top layer fossils have not been there as long as the bottom layer fossils to be found deeper in the ground
Answer:
why cant I see the picture on my screen
Answer:
See below.
Explanation:
The volume increases.
This is complies with Boyles Law:
At constant temperature P1 V1 = P2 V2 where P1, P2 are the pressures before and after and V1 and V2 are the volumes before and after.
The gases like nitrogen and oxygen are not greenhouse gases because they do not absorb infrared radiation.
<h3>What are Greenhouse gases?</h3>
Greenhouse gas is a gas that has the property of absorb infrared radiation from the Earth’s surface and reradiate back to the Earth’s surface, thus contributing to the greenhouse effect.
<h3>What is infrared radiation?</h3>
Infrared radiation is an electromagnetic radiation with wavelengths longer than those of visible light.
Carbon dioxide, nitrous oxide, methane, and water vapour are the most important greenhouse gases.
Hence, nitrogen and oxygen are not greenhouse gases despite being in the atmosphere.

Ca(OH)₂ ==> Ca²⁺ + 2 OH<span>-
Ca(OH)</span>₂ is <span>strong Bases</span><span>
</span>Therefore, the [OH-] equals 5 x 10⁻⁴ M. For every Ca(OH)₂ you produce 2 OH⁻<span>.
</span>
pOH = - log[ OH⁻]
pOH = - log [ <span>5 x 10⁻⁴ ]
pOH = 3.30
pH + pOH = 14
pH + 3.30 = 14
pH = 14 - 3.30
pH = 10.7
hope this helps!</span>
