Answer:
Ca(NO3)2 + 2 NaCl = 2 NaNO3 + CaCl2
Explanation:
On the left you have an original balance of Ca - 1, N - 2, O - 6, Na - 1, and Cl - 2, and on the right you have a balance of Ca - 1, N - 1, O - 3, Na - 1, Cl - 2.
Ca - 1 Ca - 1
N - 2 N - 1
O - 6 O - 3
Na - 1 Na - 1
Cl - 1 Cl - 2
In order to balance these, you'll have to make both sides equal. To get the N on the right to be equal to the N on the left, you'll have to multiply NaNO3 by 2, thus making it 2NaNO3. By doing this, you will offset the balance of both Na and O.
Ca - 1 Ca - 1
N - 2 N - 2
O - 6 O - 6
Na - 1 Na - 2
Cl - 1 Cl - 2
To balance the rest of the equation, you'll have to multiply both Na and Cl by 2. This will change NaCl to 2NaCl, making the balance look like this:
Ca - 1 Ca - 1
N - 2 N - 2
O - 6 O - 6
Na - 2 Na - 2
Cl - 2 Cl - 2
You will now be left with your final equation Ca(NO3)2 + 2 NaCl = 2 NaNO3 + CaCl2.

Answer:
P₂ = 13.9 atm (3 sig. figs.)
Explanation:
The pressure (P), Volume (V) relationship with Temperature (T) & mass (n) held constant is an inverse proportionality. That is Boyles Law ...
P ∝ 1/V => P = k/V => k = P·V
For two pressure-volume conditions, the proportionality constant (k) remains constant where k₁ = k₂ and P₁·V₁ = P₂·V₂ => P₂ = P₁·V₁/V₂
Given:
P₁ = 1.31 atm.
V₁ = 5.51 L
P₂ = ?
V₂ = 0.520 L
V₂ = (1.31 atm)(5.51L)/(0.520L) = 13.88096154 atm (calc. ans.) = 13.9 atm (3 sig. figs.)
Methanol has severl uses few of which are discussed below.
<h3><u>Explanation</u>:</h3>
Methanol is the simplest alcohol with chemical formula CH3OH. Its nin drinkable because its toxic when consumed.
Methanol is used for preparing acetaldehyde, formaldehyde, butandiol, acetal resins etc which are used for production of furthur high specific chemicals with high rate of purity. Its also used widely in automobile industry.
Its used to produce acetic acid, solvent esters and acetates, terepthalic acid, etc which are used in automobiles, paint industry, ink industry etc.
Its used in preparation if zero emmision fuels. Its also used to produce antifreeze, lubricants, burning alcohol, spirit etc.
Its also used to produce different cleaners and canned heat.
Its used to dress wounds, for preparation of MMA, MTOs etc.
