a_sh-v [17]3 years ago

The oxidation state of a free element (uncombined element) is zero. For a simple (monoatomic) ion, the oxidation state is equal to the net charge on the ion. For example, Cl– has an oxidation state of -1. When present in most compounds, hydrogen has an oxidation state of +1 and oxygen an oxidation state of −2.

What determines crystal size in minerals formed by lava or magma?
Burka [1]

Answer:

When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

A metal stand specifies a maximum load of 450 lb. Will it support an aquarium that weighs 59.5 lb and is filled with 37.9 L of s
DedPeter [7]

First solve the mass of 37.9 L seawater

M = 37.9 L ( 1000 ml / 1L ) ( 1.03 g / ml)

M = 39037 g

Then convert it to lb

M = 39037 g ( 1 lb / 453.592 g)

M = 86.06 lb

<span>Total weight = 86.06 lb + 59.5 lb = 145.56 lb so it can support the aquarium</span>

Water electrolysis of hcl ? Please
svp [43]

Answer:

Electrolysis (of hydrochloric acid) is a way of splitting up (decomposition) of the compound (hydrogen chloride in water) using electrical energy.

Explanation:

The electrical energy comes from a d.c. (direct current) battery or power pack supply. A conducting liquid, containing ions, called the electrolyte (hydrochloric acid), must contain the compound (hydrogen chloride) that is being broken down.
