Answer:
If a neutral atom has 22 protons inside its nucleus, it will have 22 electrons orbiting the nucleus.
Explanation:
An atom is the smallest amount of matter that undergoes chemical changes and is made up mainly of subatomic particles: electrons, protons and neutrons. The atomic nucleus is made up of protons, with a positive electric charge, and neutrons, which have no charge, while electrons, with a negative electric charge, revolve around the nucleus.
A neutral atom is one that lacks an electrical charge due to a trade-off between the number of its protons and electrons. In other words, although it has an electric charge, it is balanced between protons, electrons and neutrons. So in a neutral atom, the number of electrons equals the number of protons because the negative charge of the electrons is offset by the positive charge of the protons.
<u><em>If a neutral atom has 22 protons inside its nucleus, it will have 22 electrons orbiting the nucleus.</em></u>
The answer is 71.5g of potassium sulfate
a. 0.137
b. 0.0274
c. 1.5892 g
d. 0.1781
e. 5.6992 g
<h3>Further explanation</h3>
Given
Reaction
2 C4H10 + 13O2 -------> 8CO2 + 10H2O
2.46 g of water
Required
moles and mass
Solution
a. moles of water :
2.46 g : 18 g/mol = 0.137
b. moles of butane :
= 2/10 x mol water
= 2/10 x 0.137
= 0.0274
c. mass of butane :
= 0.0274 x 58 g/mol
= 1.5892 g
d. moles of oxygen :
= 13/2 x mol butane
= 13/2 x 0.0274
= 0.1781
e. mass of oxygen :
= 0.1781 x 32 g/mol
= 5.6992 g
Answer : The rate for a reaction will be 
Explanation :
The balanced equations will be:
In this reaction, 
and 
are the reactants.
The rate law expression for the reaction is:
![\text{Rate}=k[A]^2[B]^1](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BA%5D%5E2%5BB%5D%5E1)
or,
![\text{Rate}=k[A]^2[B]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BA%5D%5E2%5BB%5D)
Now, calculating the value of 'k' by using any expression.
Now we have to calculate the initial rate for a reaction that starts with 1.48 M of reagent A and 1.32 M of reagents B.
![\text{Rate}=k[A]^2[B]^0[C]^1](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BA%5D%5E2%5BB%5D%5E0%5BC%5D%5E1)
Therefore, the rate for a reaction will be
