3 0

Answer:

<h3>The answer is 1.93 g/mL</h3>

Explanation:

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

density =  \frac{mass}{volume}\\

From the question

mass = 8.32 g

volume = 4.3 mL

So we have

density =  \frac{8.32}{4.3}  \\  = 1.934883720...

We have the final answer as

<h3>1.93 g/mL</h3>

Hope this helps you

What is a substance consisting of two or more elements?
bixtya [17]
When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound<span>. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).

Hope this helps.</span>

_Fe2O3 + 2CO —&gt; _Fe + _CO2
soldi70 [24.7K]
<h3>Answer:</h3>

Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g)

<h3>Explanation:</h3>

Concept tested: Balancing of chemical equations

  • A chemical equation is balanced by putting appropriate coefficients on the products and reactants of the equation.
  • Balancing chemical equations ensures that chemical equations obey law of conservation of mass.
  • In this case; to balance the above equation we put the coefficients, 1, 3, 2, and 3 on the reactants and products.
  • Therefore; the balanced chemical equation for the reaction is;

      Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g)

How can the speed of solvent molecules be slowed down?
Darina [25.2K]

Explanation:

The speed of molecules increases when temperature is increased as it will result in more number of collisions between the molecules. Thus, there will be  increase in kinetic energy of molecules and increase in the speed of solvent molecules.

Whereas on decreasing the temperature, the kinetic energy of molecules will decrease. This will result in less number of collisions between the molecules. Therefore, the speed of solvent molecules will slow down.
