Answer:
Explanation:
a. the salt produced would be Mg3N2(magnesium nitride)
b. magnesium loses 2 electron to form Mg2+ ion and nitrogen gains 3 electron to form n3-
when several of these ions come together 3 Mg2+ ion combine with 2 n3- ion to form Mg3N2 thus Mg getting six electron from nitrogen to form a ionic bond.
c. the reaction is not balanced Mg + N2 = Mg3n2
to make it balanced the reaction should be 3 Mg + N2 = Mg3N2.
the reaction was not balanced before because the number of Mg on both side of the reaction was not equal.
d. magnesium nitrate has formula Mg(NO3)2 is formed when Mg combines with nitrogen and oxygen Mg + N2 + o2
Answer:
I'll take a gander at your question
Explanation:
If you mean the Earth's crust, your answer is The Mantle.
Protons have the same mass as B. Neutrons. They have almost the same exact mass.
Answer:
d- 7.58 L
Explanation:
According to Charles's law, the temperature in Kelvin is proportional to the volume of a dry gas when the pressure is constant.
Mathematically, V1/T1 = V2/ T2
V1= initial volume= 6.6 L
T1= Initial temperature= 115 °C= (115 °C +273)=388K
V2= final volume
T2= final temperature= 173 °C= ( 173 °C+ 273)= 446K
Substitute the values,
V2=( V1 × T2)/ T1
= (6.6×446)/388
= 2943.6/388
= 7.6L
Answer: will be five times higher
If 4 moles of gas are added to a container that already holds 1 mole of gas, the pressure inside the container
will be five times higher due to the change in the amount of gas.
Explanation:
4 moles of gas + 1 mole of gas = 5 moles of gas.
Also, the ideal gas equation pV = nRT
show that pressure is directly proportional to number of moles; so, if 1 mole of gas contains molecules that move randomly and freely under pressure inside the container; addition of 4 extra moles will sum up to 5moles of gas molecules moving randomly under pressure, and that is five times higher as well.
