Answer:

Heat, temperature, and thermal energy are related because they all work with each other.

Explanation:

First of all, everything start's off with temperature. It starts off low. But when heat is added to it, it rises and the temperature goes up. This causes thermal energy to the objects touching it. The hotter it is the faster the particles move and the more kinetic energy they have.

Which balanced equation represents a redox reaction? a. AgNO3(aq) +NaCl(aq) →AgCl(s) +NaNO3(aq) b. H2CO3(aq) →H2O() + CO2(g) c.

Aleks [24]

Answer : The correct option is, (D) $Mg(s)+2HCl(aq)\rightarrow MgCl_2(s)+H_2(g)$

Explanation :

(A) $AgNO_3(aq)+NaCl(aq)\rightarrow AgCl(s)+NaNO_3(aq)$

This reaction is a double displacement reaction in which the cation and anion of two reactants are exchange their places to give two different products.

(B) $H_2CO_3(aq)\rightarrow H_2O(l)+CO_2(g)$

This reaction is a decomposition reaction in which the larger molecule decomposes to give two or more products.

(C) $NaOH(aq)+HCl(aq)\rightarrow NaCl(s)+H_2O(aq)$

This reaction is a neutralization reaction in which an acid and a base react to give a salt and water as a product.

(D) $Mg(s)+2HCl(aq)\rightarrow MgCl_2(s)+H_2(g)$

This reaction is a redox reaction in which the oxidation and reduction reaction occur simultaneously.

Oxidation reaction is the reaction in which a substance looses its electrons. In this oxidation state increases.

Reduction reaction is the reaction in which a substance gains electrons. In this oxidation state decreases.

In this reaction, magnesium shows oxidation due to change in oxidation number from (0) to (+2) and hydrogen shows reduction due to change in oxidation number from (-1) to (0).

Hence, the correct option is, (D)

So in general what rule can you make about substances that dissolve in solvent?

spin [16.1K]

In general, SOLUBILITY is an ability of a substance to dissolve. In the process of dissolving, the substance which is being dissolved is called a solute and the substance in which the solute is dissolved is called a solvent. A mixture of solute and solvent is called a solution.

What is the empirical formula for a compound that contains 38.77% Cl and 61.23% O?

Leno4ka [110]

W(Cl)=0.3877
w(O)=0.6123
M(Cl)=35.5 g/mol
M(O)=16.0 g/mol

ClₐOₓ
M(ClₐOₓ)=35.5a+16.0x

w(Cl)=35.5a/(35.5a+16.0x)
w(O)=16.0x/(35.5a+16.0x)

solve a system of two equations with two unknowns
35.5a/(35.5a+16.0x)=0.3877
16.0x/(35.5a+16.0x)=0.6123

a=2
x=7

Cl₂O₇ is the empirical formula

What would increase the amount of your carbon dioxide output?

SSSSS [86.1K]

Answer:

Consuming electricity: Burning fossil fuels emits CO2, with coal releasing twice as much of the gas as petroleum. Worldwide, fossil fuels generate 85 percent of electricity. The number of coal-burning plants will increase as China and India continue to industrialize.
