Answer:
1) S2N
2)ClI
Explanation:
A chemical formula shows the relative ratio of atoms present in a compound. When we write a chemical formula, we have an idea of the ratio in which atoms combine in the compound of interest. This is a great clue when we are attempting to elucidate the structure of the compound.
For hexasulphur mononitride,the formula of the compound must be S6N3, this reduced to lowest terms to give S2N.
Similarly, the formula for chlorine monoiodide is ClI as shown in the answer above.
P4(s) + 6Cl2(g) → 4PCl3(l)
n P4 = m P4 / Mr P4
n P4 = 18.74 / 123.88
n P4 = 0.151 mol
n Cl2 = m Cl2 / Mr Cl2
n Cl2 = 9.6 / 70.9
n Cl2 = 0.135 mol
Cl2 act as <u>limiting reactant</u>
n PCl3 = (coef. PCl3)/(coef. Cl2) • n Cl2
n PCl3 = (4/6) • 0.135
n PCl3 = 0.09 mol
m PCl3 = n PCl3 • Mr PCl3
m PCl3 = 0.09 • 137.33
m PCl3 = 12.36 gr

<span>Barometric pressure is just the same as
atmospheric pressure. It is called barometric pressure because the instrument
used to measure is called barometer. It is the pressure exerted by the air at a
certain altitude. Since it is the pressure exerted by the air, it is also known
as the weight of the air above the Earth. Depending on the altitude at which
the measurement is done, barometric or atmospheric pressure varies, but the
barometric pressure at sea level is 1 atm (atmosphere). It is equivalent to
101325 Pa (Pascal), 760 torr, 760 mm Hg and 1.01325 bar.</span>
