Question four is : Gaseous state
Question five is : A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
Hope this helps!
Have a great day!
Answer: A. CaO
Took the test already.
Answer is: mass of methanol is 528.32 grams.
N(CH₃OH) = 9.93·10²⁴; number of methanol molecules.
n(CH₃OH) = N(CH₃OH) ÷ Na (Avogadro constant).
n(CH₃OH) = 9.93·10²⁴ ÷ 6.022·10²³ 1/mol.
n(CH₃OH) = 16.49 mol; amount of substance.
m(CH₃OH) = n(CH₃OH) · M(CH₃OH).
m(CH₃OH) = 16.49 mol · 32.04 g/mol.
m(CH₃OH) = 528.32 g.

Explanation:
A form of severe weather is drought, which is a prolonged period of persistently dry weather (that is, absence of precipitation).This can cause wild fires which impact the growth of trees.They cause the tree the release carbon dioixide rather than store!
