Answer:
32.4 K
Explanation:
Initial pressure P1= 50.0mmHg
Initial temperature T1= 540K
Final temperature T2=????
Final pressure P2= 3 mmHg
From
P1/T1= P2/T2
P1T2= P2T1
T2= P2T1/P1
T2= 3×540/50.0= 1620/50.0
T2= 32.4 K
When perfume or cologne is sprayed into the air, it turns into a gas and its particles mix with other air particles that quickly move around the room. This is because gas is the least dense of the three states of matter. It moves quickly into any space or volume because it has the least density. This is called diffusion, when molecules or particles move from areas with high concentration to low concentration areas.
Answer:
The last choice.
Explanation:
It does not conduct electricity in any form.
They have no free electrons and do not ionise.
The statement which correctly describe the relationship between the reactants and the yield is this: 'the theoretical yield is calculated from the amount of the limiting reactants present'. The theoretical yields is the ideal maximum amount of a product that can be produced during a chemical reaction while the limiting reactant is the reactant that determines the maximum amount of product that can be formed.
Answer:
13 nuclei
Explanation:
From the question, the fission of one nucleus produces three neutrons which causes more nuclei to undergo fission.
This implies that, after the first fission, three neutrons cause three nuclei to undergo fission. The three nuclei that underwent fission produces nine neutrons which causes the fission of nine nuclei.
All together we the number of nuclei that underwent fission as;
1 + 3 + 9 = 13 nuclei.
