A brick has a volume of 475 cubic centimeters and a mass of 912 grams. Calculate itsdensity.
Write your answer to the hundredths place

Answers

Answer 1
Answer:

Answer:

1.92 g/cm³

Explanation:

The density of a substance can be found by using the formula

density = (mass)/(volume) \n

From the question we have

density = (912)/(475) \n

We have the final answer as

1.92 g/cm³

Hope this helps you

The oxidation # (charge) of an element called "lindenium "Ld is + 1 and the oxidation # (charge) of an element called "mendezine symbol "Mz, is -2. What is the chemical formula for the compound called lindenium mendezide?

Answers

Answer:

Ld₂Mz

General Formulas and Concepts:

Chemistry - Compounds

  • Valence shells
  • Writing chemical compounds
  • Balancing charges

Explanation:

Step 1: Define

"Lindenium" Ld w/ oxidation charge of +1

"Mendezine" Mz w/ oxidation charge of -2

Step 2: Write Compound

To balance out the charges to be neutral (0), we must counter balance the amount of Ld's with Mz's. We need 2 Ld's with 1 Mz to create a compound with a neutral charge:

2Ld¹⁺ + Mz²⁻

2(+1) + (-2) = (+2) + (-2) = 0 (neutral charge)

Therefore, our compound must be Ld₂Mz.

Which of the following affects the rate of a chemical reaction?A. the presence of a catalyst
B. the temperature
C. the concentration of reactants
D. all of the above

Answers

The following that affects the rate of a chemical reaction is the presence of catalyst, temperature, and concentration of reactant. The correct option is D.

What is the rate of a reaction?

The rate of reaction is the speed of the reaction at which a reaction takes place.

The catalyst increases the rate of reaction.

The increase in temperature increases the rate of reaction.

Thus, the correct option is D. all of the above.

D. A ll of the above. catalyst reduces the activation energy thereby making the reaction faster. an increase in temperature  increases the kinetic energy and no of collisions making reaction faster for an endothermic reaction while decrease in temperature favors an exothermic reaction.
increase in concentration increases the molecules reacting so the reaction is faster and vice versa.

Why does salt dissolve in water?

Answers

The water dissolves the salt because the water molecules are able to interact with the salt-forming particles, called ions. When the water Interacts with the trainers of the salt ions, the solid salt crystal structure Suffers breakdown, until the trainers of the salt ions are completely surrounded by water molecules. At this time the salt is fully dissolved by water.
