I’m not sure but I think the answer is substance . Because you can change the temperate of a substance but it will still be that substance . You can change all of these things except the substance itself

Carbon monoxide and chlorine combine in an equilibrium reaction to produce the highly toxic product, phosgene (COCl2 ) CO(g) Cl2

Answer:

Reaction will proceed towards forward direction.

Explanation:

Balanced reaction: $CO+Cl_{2}\rightleftharpoons COCl_{2}$

Reaction quotient ( $Q_{c}$ ) for this reaction is represented as:

$Q_{c}=\frac{[COCl_{2}]}{[CO][Cl_{2}]}$

Here, [CO] = [ $Cl_{2}$ ] = 0.010 M and [ $COCl_{2}$ ] = 0.070 M

So, $Q_{c}=\frac{0.070}{(0.010)^{2}}$ = 700

As $Q_{c}$ > $K_{c}$ therefore reaction will proceed towards forward direction i.e. more $COCl_{2}$ will be produced.

Answer:

8.3334%

Explanation:

You have two masses. To find the percent of sodium chloride in water by mass, you divide the mass of NaCl by water. First, make both units the same. Easiest is to convert kg into g. 1.5kg = 1500g

125g NaCl/1500g H2O = 0.0833333333 ==> 8.3334%
