Answer:
Anhydride, any chemical compound obtained, either in practice or in principle, by the elimination of water from another compound. Examples of inorganic anhydrides are sulfur trioxide, SO3, which is derived from sulfuric acid, and calcium oxide, CaO, derived from calcium hydroxide
Explanation:
<h3>
<em><u>examples</u></em><em><u>.</u></em></h3>
1)acid anhydride.
2)basic anhydrides.
<h3>
<em><u>reactions</u></em><em><u>. </u></em></h3>
1)reaction with water
(CH3CO)2O + H2O → 2 CH3CO2H.
Molas mass C6H12O6 = 180.15 g/mol
1 mole C6H12O6 -------------- 180.15 g
?? molesC6H12O6 ------------ 3.10x10⁻³ g
3.10x10⁻³ x 1 / 180.15 => 0.00001720 moles
1 mole ------------------------- 6.02x10²³ molecules
0.00001720 moles ---------- ??
0.00001720 x (6.02x10²³) / 1 => 1.035x10¹⁹ molecules

Answer:
Tides: the rise and fall of sea levels due to gravitational forces
Tidal bulges: two ocean bulges created on opposite sides of the earth due to the moons gravitational pull and the oceans resistance
Spring tide: tides where there is the greatest difference between high and low tide
Neap tide: tides where there is the least difference between high and low tide
When thermal energy is added, the motion of particles increases.
This can be thought of when thinking of a gas. We know that a gas includes particles that move fast and are spaced far apart from each other. On the opposite side of the spectrum, we know that a solid includes particles that are closely packed together with limited movement.
Using those examples, we know that a solid usually occurs at colder temperatures (with low thermal energy), and gases occur at warmer temperatures (with high thermal energy).
Therefore, when thermal energy is added, particle motion increases.
