In the reaction ___h2+n2 ->2 NH3, what coefficient should be placed in front of H2 to balance the reaction?
Nataly_w [17]
In order to balance this equation you need to count each element and how many of the individual elements are in the equation.
_H2+N2=2 NH3
You multiply the 2 (Which is the coefficient) by the 3 (which is the subscript) This would equal 6 which indicated there are 6 hydrogen atoms on the right side so the left side should also have 6 hydrogen atoms

The missing coefficient on the left side must multiple the 2 to become 6 hydrogen

Why does the pressure inside a container of gas increase?
yan [13]
Pressure is a scientific parameter that allows us to determine the amount of force being exerted per unit area. The increase in the pressure inside a container containing a gas may be brought upon by the decrease in volume, increase in temperature, or merely by additional of more gas molecules.

When hot lava reaches seawater, the salts in the water react with steam to form gaseous hydrochloric acid. You are given an unba
qaws [65]
Cl⁻ + H₂O(g) = HCl(g) + OH⁻

w - it is percent chloride ions in solid sea salt (as a rule 55%)

m - it is the mass of sea salt

m(Cl⁻)=mw/100

m(Cl⁻)/M(Cl)=V(HCl)/V₀

mw/{100M(Cl)}=V(HCl)/V₀

m=100M(Cl)V(HCl)/{wV₀}  (<span>the mass of solid sea salt)</span>

V₀=22.4 L/mol
M(Cl)=35.45 g/mol

for example:
V(HCl)= 1.0 L
w=55%

m=100×35.45×1.0/{55×22.4}=2.88 g
