Answer:

Kindly check Explanation

Explanation:

Given the chemical equation:

2 Mg(s) + O2(g) → 2 MgO(s)

2 molecules of Magnesium + Oxygen gas (Reactant)

→ ( yield)

2 molecules of magnesium oxide (product)

2 in Mg and MgO (coefficients)

2 in Oxygen gas (subscript)

Solid (s) - physical state of Reactant Mg

Gas (g) - physical state of Reactant O2

Solid (s) - physical state of product 2MgO

How much heat, in calories, is given off when 1.25 grams of silver is cooled from 100.0 degrees Celsius to 80 degrees Celsius? (
lapo4ka [179]
The heat required to raise the temperature of a certain mass of sample to a specific temperature change, we use the formula mCpΔT where m is mass, Cp is the specific heat of the substance and ΔT is the temperature change. In this case, we substitute and form 1.25 g x 0.057 cal/g C *20 C equal to 1.425 calories.

What effect does light have on plant growth?
Varvara68 [4.7K]

Explanation:

Light intensity influences the manufacture of plant food, stem length, leaf color and flowering. Generally speaking, plants grown in low light tend to be spindly with light green leaves. A similar plant grown in very bright light tends to be shorter, better branches, and have larger, dark green leaves.

which of the following best helps explain why an increase in temperature increases the rate of a chemical reaction?
NeTakaya

The given question is incomplete. The complete question is as follows.

Which of the following best helps explain why an increase in temperature increases the rate of a chemical reaction?

(a)   at higher temperatures, high-energy collisions happen less frequently.

(b)  at low temperatures, low-energy collisions happen more frequently.

(c)   at higher temperatures, less-energy collisions happen less frequently.

(d)  at higher temperatures, high-energy collisions happen more frequently

Explanation:

When we increase the temperature of a chemical reaction then molecules of the reactant species tend to gain kinetic energy. As a result, they come into motion which leads to more number of collisions within the molecules.

Therefore, chemical reaction will take less amount of time in order to reach its end point. This means that there will occur an increase in rate of reaction.

Thus, we can conclude that the statement at higher temperatures, high-energy collisions happen more frequently, best explains why an increase in temperature increases the rate of a chemical reaction.
