Explanation:
MWQ means the minimum weighable quantity.
Mathematically, MWQ =
or, MWQ =
It is given that sensitivity is 4.5 mg and maximum permitted error is 3.6%.
Therefore, fraction error = = 0.036
Hence, we will calculate MWQ as follows.
MWQ =
=
= 125 mg
Thus, we can conclude that the MWQ of the given balance is 125 mg.

Here's what I get
Explanation:
SiO₂ + 4HF ⟶ SiF₄ + 2H₂O
The molar ratios are the same as the coefficients in the balanced equation.
Some of the molar ratios are
SiO₂:HF = 1:4
SiO₂:SiF₄ = 1:1
SiO₂:H₂O = 1:2
HF:SiF₄ = 4:1
HF:H₂O = 4:2
SiF₄:H₂O = 1:2

Answer:
Increase
Explanation:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
If the initial temperature and pressure is standard,
Pressure = 1 atm
Temperature = 273.15 K
then we increase the temperature to 400.0 K, The pressure will be,
1 atm / 273.15 K = P₂/400.0K
P₂ = 1 atm × 400.0 K / 273.15 K
P₂ = 400.0 atm. K /273.15 K
P₂ = 1.46 atm
Pressure is also increase from 1 atm to 1.46 atm.
