Answer:
Basalt forms when lava cools quickly at the surface. This quick cooling rate results in very small mineral grains. Pumice is formed when volcanoes erupt explosively. It comes from the same kind of magma which would form granite or rhyolite, that is, a magma that contains lots of silica (quartz). Magma with lots of silica is usually thick and sticky
Explanation:
Answer:
"Nitrate" is a polyatomic ion forms A neutral compound when combined with group a1 monotonic ion in a 1:1
Explanation:
Nitrate is a polyatomic ion with the molecular formula NO⁻ ₃. Organic complexes that comprise the nitrate ester as a functional group are also named nitrates. Nitrates are shared apparatuses of fertilizers and explosives. Almost all nitrate salts are soluble in water. Usually nitrates that enter the body by eating or drinking leave the body without harm. These nitrites in the blood cause changes in hemoglobin, or the molecules that help move oxygen in the body. Nitrates can make it so that less oxygen is available for the body to function properly.
Answer:
NaF and KBr
Explanation:
These two substances contain pure ionic bonds. LiI is a covalent compound because of the Large polarizing power of Li and the high polarizability of I(Fajan's rules). The other compounds mentioned are organic compounds. They are not soluble in water at all.
Your answer is B. radio waves have shorter wavelenghts than microwaves.
Have a great day
Physical property of gas:
There are a lot, here are some examples:
=> Air
=> Oxygen
=> Carbon dioxide
=> Flourine
=> Phosphine
=> Argon
=> Carbon monoxide
This examples are all gases and each of these gases has its own physical property. The only thing that they makes them the same are that, they are gas with lesser molecules. Usually gas density is lesser compare to the solid or liquid and most gases has undefined melting point.
