Answer:
6 chromosomes.
Explanation:
In a normal cell with 46 chromosomes, there are 23 chromosomes at the end of meiosis. So using that example we can determine that there will be 12 chromosomes at the beginning, and 6 chromosomes at the end.
Answer:
B. Reese's yard
Explanation:
Because Reese's yard is full of rocks, rock's don't absorb water, while Chris' yard is only soil, which will make his yard absorb water quicker.
1) Reaction:
Mg(s) + 2HCl (aq) ----> H2(g) + MgCl2(aq)
2) Analysis
An increase in pressure affects directly the rate of reaction involving reactiong gases. Changing the pressure where there are only solids or liquids does not affect the rate of reaction.
This reaction is not an equilibrium, the reaction is only forward. So, the reacting components, Mg(s) and HCl(aq) are a solid and a liquid.
Therefore, the reaction is not affected by the change in pressure.
Answer: the reaction is not affected at all.
Answer:
using the formula of numbers of molecules
Explanation:
mass /Mr 44/44=1 molecules of carbon dioxide present
(Mr of carbon dioxide is ( 2*16)+12=44
Now time by Abogadros constant 1*6.002*10^23
molecules of CO2 are present = 6.002*10^23
⇒ only atom consist of 1 electron and one proton
Rest atoms greater than 1 atomic number (neutral) have neutrons,electrons and protons.
