Lelu [443]3 years ago

Answer:

See below.

Step-by-step explanation:

We call this conversion factor the <em>molar ratio.</em>

1. Start with the <em>balanced equation </em>

NiCO₃ + 2HCl ⟶ NiCl₂ + H₂O + CO₂

2. Note the <em>coefficients</em> of the substances

The equation tells you that 1 mol of NiCO₃ reacts with 2 mol of HCl·

Thus, the conversion factor is either (1 mol NiCO₃/2 mol HCl) or (2 mol HCl/1 mol NiCO₃).

You choose the one that gives the correct units for the answer.

<em>For example</em>, if the question was, "How many moles of HCl will react with x mol of NiCO₃," you would write

x mol NiCO₃ × (2 mol HCl/1 mol NiCO₃) ⟶ 2x mol HCl

Notice that putting "mol HCl" in the numerator and "mol NiCO₃" in the denominator cancels "mol NiCO₃" and gives you the desired units of "mol HCl" in the answer .

My name is Ann [436]

Answer:

The cooler water is denser

Explanation:

Convection drives the boiling of water placed on a stove in a kettle.

During convection, heat is circulated by density differences in portions of a fluid.

Convection is a form of heat transfer in fluids especially gas and liquid.

  • In boiling water, the heat is supplied to the base of the stove.
  • The water at the bottom on heat becomes lighter as the molecules gain more kinetic energy.
  • The colder part of the water on top sinks to replace the less dense on below.
  • This exchange sets up convection cells in the kettle.

e-lub [12.9K]

Answer:

C6H12O6 —> 2C2H5OH + 2CO2

Explanation:

The equation for the reaction is given below:

C6H12O6 —> C2H5OH + CO2

We can balance the equation above as follow:

There are 12 atoms of H on the left side and 6 atoms of the right side. It can be balance by putting 2 in front of C2H5OH as shown below:

C6H12O6 —> 2C2H5OH + CO2

There are 6 atoms of C on the left side and 5 atoms on the right side. It can be balance by putting 2 in front of CO2 as shown below:

C6H12O6 —> 2C2H5OH + 2CO2

Now the equation is balanced.
