Na2CO3 + 2HCl ---------> 2NaCl + CO2 + H2O How many moles of NaCl are produced from the reaction of 1.67 x 1022 molecules of Na2CO3 with excess HCl?

Answers

Answer 1

Answer:

0.0554 moles of NaCl are produced from the reaction of 1.67*10²² molecules of Na₂CO₃ with excess HCl.

Explanation:

The balanced reaction is:

Na₂CO₃ + 2 HCl → 2 NaCl + CO₂ + H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

Na₂CO₃: 1 mole HCl: 2 moles NaCl: 2 moles CO₂: 1 mole H₂O: 1 mole

On the other hand, Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number applies to any substance.

In this case, you can apply the following rule of three: if 6.023*10²³ molecules of Na₂CO₃ are contained in 1 mole, 1.67*10²² molecules will be contained in how many moles?

[tex]amount of moles=\frac{1.67*10^{22}molecules*1mole }{6.023*10^{23}molecules}[/tex]

amount of moles= 0.0277 moles

In this case, you can apply the following rule of three: if by stoichiometry 1 mole of Na₂CO₃ produces 2 moles of NaCl, 0.0277 moles of Na₂CO₃ will produce how many moles of NaCl?

[tex]amount of moles of NaCl=\frac{0.0277 moles of Na_{2} CO_{3}*2 moles of NaCl }{1 mole of Na_{2} CO_{3}}[/tex]

amount of moles of NaCl= 0.0554 moles

0.0554 moles of NaCl are produced from the reaction of 1.67*10²² molecules of Na₂CO₃ with excess HCl.

Lewis structures are also called as electron dot structures and can be drawn if the molecular formula of a compound is known. It provides information regarding the nature of bond and the position of atoms .

They are also capable of exhibiting the lone pair if any present in a molecule or compound.Lewis defined a base to be an electron pair donor and an acid to be an electron pair acceptor.

They are capable of reflecting electronic structure of elements and even the pairing of electrons . In the diagram, each dot represents an electron while a pair of dots represent a bond between the atoms.It helps in understanding the  bonding between the two atoms.

How many liters of CH4 gas are there in 1.20 moles of CH4 when the gas is held under standard conditions?

Please answer quickly!

Answers

Answer:

26.88 L

Explanation:

When any gas is held under standard conditions, one mol will occupy 22.4 liters.

With the above information in mind, we can calculate how many liters would 1.20 moles of CH₄ gas occupy under standard conditions:

1.20 mol * 22.4 L/mol = 26.88 L

So 1.20 moles of CH₄ would occupy 26.88 liters.

In a chemical reaction, the reactants (beginning elements or compounds) but have the same number and type of atoms as the products (the new substance created). This is an example of...
a) law of conservation of mass
b) law of conservation of energy
c) covalent bonding
d) product synthesis

3 Mg + N2 Mg3N2




Round answer to 4 sig-figs.

Answers

Answer:

0.1011 moles of N₂

Explanation:

This is the reaction:

3 Mg + N₂ → Mg₃N₂

3 moles of magnesium can react to 1 mol of nitrogen in order to produce 1 mol of magnesium nitride.

We can solve this by a rule of three:

3 mol of Mg need 1 mol of N₂ for the reaction

Then, 0.3034 moles of Mg may react to (0.3034 . 1) / 3 = 0.1011 moles of nitrogen.

Which change does not increase the speed of reaction between zinc and hydrochloric acid?

Answers

When solid zinc is dropped into hydrochloric acid solution, it falls to the bottom due to its higher density. The reaction occurs at the surface of the zinc metal and generates hydrogen gas that bubbles up through the solution. You can tell that the rate increases because the rate of bubble formation increases. This will naturally occur because the reaction is exothermic and will warm the solution around the zinc metal. The higher temperature will increase the reaction rate.

If you want a more quantitative analysis of reaction rate, you can perform the experiment in a eudiometer tube that is inverted and completely filled with liquid. As the hydrogen gas collects in the tube you can measure its accumulated volume with time. That will allow you to determine an approximate kinetic rate law for the process. The rate law determined in this manner will suffer from error due to temperature and surface area changes as well as gas volume error due to water vapor. But, it is an interesting application of chemical kinetics.

By adding the decreasing the temperature, the speed of the reaction will not be increased.

What is speed of the reaction ?

The reaction rate, which is a measure of how quickly reactants are consumed as well as products are created, determines the speed of a reaction.

When the temperature is lowered, the molecules move more slowly and collide less. The reaction's speed is slowed as the temperature drops.

Therefore, by adding the decreasing the temperature, the speed of the reaction will not be increased.
