Answer:

chemical energy

In this case plants convert light energy into chemical energy, (in molecular bonds), through a process known as photosynthesis. Most of this energy is stored in compounds called carbohydrates. The plants convert a tiny amount of the light they receive into food energy.

Answer: Chemical energy

Explanation: In this case plants convert light energy (1) into chemical energy, (in molecular bonds), through a process known as photosynthesis. Most of this energy is stored in compounds called carbohydrates. The plants convert a tiny amount of the light they receive into food energy.

Answer:

- Ammonium perchlorate: acidic, so its pH will be less than 7.

- Sodium fluoride: basic, so its pH will be greater than 7.

- Calcium chloride: neutral, so its pH will be approximately equal to 7.

- Calcium nitrate: neutral, so its pH will be approximately equal to 7.

Explanation:

Hello,

In this case, we can foresee whether the given bases are acidic, neutral or basic by knowing both the acid and base they come from. In such a way, if a strong acid reacts with a strong base, the resulting salt is neutral, next, if a strong acid reacts with a weak base the resulting salt is acidic and if a weak acid reacts with a strong base the resulting salt is basic. Therefore, we have:

- Ammonium perchlorate: it comes from ammonium hydroxide or ammonia that are weak bases and perchloric acid which is a strong acid, therefore the salt is acidic so its pH will be less than 7.

- Sodium fluoride: is comes from sodium hydroxide which is a strong base and hydrofluoric acid which is a weak acid, therefore the salt is basic so its pH will be greater than 7.

- Calcium chloride: it comes from calcium hydroxide and hydrochloric acid which are both strong, for that reason the resulting salt will be neutral so its pH will be approximately equal to 7.

- Calcium nitrate: it comes from calcium hydroxide and nitric acid which are both strong, for that reason the resulting salt will be neutral so its pH will be approximately equal to 7.

Best regards.

The substance used by homeowners and municipal workers to melt ice on sidewalks and roadways is usually calcium chloride rather

Verizon [17]

Answer:

1. It dissolves much more ice faster than sodium chloride

2. Calcium chloride is more effective in melting ice at lower temperatures.

Explanation:

Salts are used to melt ice on roadways and sidewalks because they help to lower the freezing point of water.

Sodium chloride and calcium chloride are both salts used for this purpose but calcium chloride is usually preferred for the following two reasons:

1. It dissolves much more ice faster than sodium chloride: Calcium chloride dissolves much more ice faster than sodium chloride because when it dissociates, it produces three ions instead of the two produced when sodium chloride. Therefore, the heat of hydration of its ions is greater than that of sodium chloride.

2. Calcium chloride is more effective in melting ice at lower temperatures. It lowers the freezing point of water more than sodium chloride. Calcium chloride is able to lower the freezing point of water to about -52°C while sodium chloride only lowers it to about -6°C.

How many moles are present 560.0 g of iron (lll) sulfate

xxMikexx [17]

Answer:

1.400 mol

Explanation:

To convert grams to moles, you will need the molar mass. The molar mass of iron(iii) sulfate is 399.88 g/mol. Divide grams by the molar mass to find moles.

(560.0 g)/(399.88 g/mol) = 1.400 mol

There are 1.400 mol present in 560.0 g of iron(iii) sulfate.
