Compared to the mass and the penetrating power of an alpha particle, a beta particle has(1) less mass and greater penetrating po
seropon [69]

Answer is (1) - less mass and greater penetrating power.


Alpha particle is a ₂⁴He nucleus while beta particles are electrons. Hence, the mass of alpha particle is greater than the mass of beta particle. But, the penetrating power is higher in beta particle than alpha particle. Alpha particles can be blocked by few papers but beta particles can go through those papers.

Initially, [NH3(g)] = [O2(g)] = 3.60 M; at equilibrium [N2O4(g)] = 0.60 M. Calculate the equilibrium concentration for NH3.
natima [27]

The question is incomplete, here is the complete question:

Consider the reaction  4NH_3(g)+7O_2(g)\rightarrow 2N_2O_4(g)+6H_2O(g)

Initially, [NH_3(g)]=[O_2(g)] = 3.60 M; at equilibrium [N_2O_4(g)]=0.60M  . Calculate  the equilibrium concentration for NH_3

<u>Answer:</u> The equilibrium concentration of ammonia is 2.8 M

<u>Explanation:</u>

We are given:

Initial concentration of [NH_3(g)] = 3.60 M

Initial concentration of [O_2(g)] = 3.60 M

For the given chemical equation:

                     4NH_3(g)+7O_2(g)\rightarrow 2N_2O_4(g)+6H_2O(g)

Initial:               3.60        3.60            

At eqllm:      3.60-4x     3.60-7x           2x             6x

We are given:

Equilibrium concentration of [N_2O_4(g)] = 0.60 M

Evaluating the value of 'x'

\Rightarrow 2x=0.60\\\\\Rightarrow x=\frac{0.60}{2}=0.2

So, equilibrium concentration of NH_3=(3.60-4x)=(3.60-(4\times 0.2))=2.8M

Hence, the equilibrium concentration of ammonia is 2.8 M

9) After lab, all of Darrel’s friends looked at his data and laughed and laughed. They told him that he was 30.8% too low in the
zaharov [31]
If he was 30.8% too low, it means that he was at 69.2% of the boiling point needed. So 50o C is 69.2% of total.

In order to know what 100% is, you can divide the number by it's percentage and then multiply it by a hundred.

So: 50/30.8=1.623
1.623*100=162.3
So the correct boiling point of the liquid he was working with in the lab is 162.3 oC

NH₄NO₃ → N₂O + 2H₂O When 45.70 g of NH₄NO₃ decomposes, what mass of each product is formed?
Anna007 [38]

Answer: 25.13 g of N_2O  and 20.56 g of H_2O will be produced from 45.70 g of NH_4NO_3

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} NH_4NO_3=\frac{45.70g}{80.04g/mol}=0.571moles

The balanced chemical equation is:

NH_4NO_3\rightarrow N_2O+2H_2O  

According to stoichiometry :

1 mole of NH_4NO_3 produce = 1 mole of N_2O

Thus 0.571 moles of NH_4NO_3 will require=\frac{1}{1}\times 0.571=0.571moles  of N_2O  

Mass of N_2O=moles\times {\text {Molar mass}}=0.571moles\times 44.01g/mol=25.13g

1 mole of NH_4NO_3 produce = 2 moles of H_2O

Thus 0.571 moles of NH_4NO_3 will require=\frac{2}{1}\times 0.571=1.142moles  of H_2O  

Mass of H_2O=moles\times {\text {Molar mass}}=1.142moles\times 18g/mol=20.56g

Thus 25.13 g of N_2O  and 20.56 g of H_2O will be produced from 45.70 g of NH_4NO_3
