They might not be able to get enough sunlight in some cases and might die from it
According to the research, the correct option is 3, Igneous rocks are those formed from a molten product from volcanic activity.
<h3>What are Igneous rocks?</h3>
They are rocks of high resistance, isotropy, brittleness and density that are created from the cooling and solidification of the magma, whether fragmented or compact, that form at erupting volcanoes, that is, this substance, made up of molten rocks and other elements, is found inside the planet.
When the cooling process takes place superficially and quickly, extrusive igneous rocks are produced, among which are obsidian and basalt, they usually appear after the eruption of a volcano, since the ejected lava solidifies.
Therefore, we can conclude that according to the research, the correct option is 3, Igneous rocks are those formed from a molten product from volcanic activity.

It has to be dilute since the crystal dissolved and unsaturated for the same reason so B
Answer;
= 18.24
Explanation;
The ratio of N and O in the formula NO2 IS 1:2
Mass of nitrogen gas is 0.500 g
Moles of nitrogen will be;
= 0.500/16 = 0.03125 moles
Therefore;
The moles of Oxygen from the ratio will be;
= 0.03125 × 2 = 0.0625 moles
But; 0.0625 moles is equal to 1.140 g of Oxygen
The atomic number (mass in 1 mole) will be;
= 1.140 /0.0625
= 18.24
Thus the atomic number of Oxygen from the data is 18.24
Answer:
V2 gas = 2.33 L
Explanation:
assuming ideal gas:
∴ n gas = 1 mol
∴ P1 standard = 1 atm
∴ V1 gas = 3.5 L
∴ P2 = 1.5 atm ⇒ V2 = ?
state 1:
∴ P1V1 = nRT1
⇒ P1V1/T1 = nR
state 2:
⇒ P2V2/T2 = nR
(1) = (2)
⇒ P1V1/T1 = P2V2/T2
assiming: T1 = T2
⇒ P1V1 = P2V2
⇒ V2 = P1V1/P2
⇒ V2 = ((1 atm)(3.5 L))/(1.5 atm)
⇒ V2 = 2.33 L
