We have 25cm^3 of 0.1mol AgNO3.
25cm^3 = 0.025L, so we have 0.025 x 0.1 = 0.0025mol AgNO3, so
0.0025AgNO3 + 0.0025NaCl = 0.0025AgCl + 0.0025NaNO3
Change in Free Energy: ΔG(20C) = -0.064kJ (negative, so the reaction runs)
Change in Enthalpy: ΔH(20C) = -0.110kJ (negative, so the reaction is exothermic)
This reaction produces 0.358g of AgCl and 0.213g of NaNO3

Answer:
Cl-
Explanation:
Neutral (Cl) have 7 electron, but Cl- have 8 electron due to gain of 1 electron
Answer: A
Explanation: Because a gas can turn into a liquid
Explanation:
“This new data set shows that as surface temperature increases, so does atmospheric humidity,” Dessler said. “Dumping greenhouse gases into the atmosphere makes the atmosphere more humid. And since water vapor is itself a greenhouse gas, the increase in humidity amplifies the warming from carbon dioxide."
The temperature that the balloon will expand to 3.50 l is 463.56 K
<em><u> calculation</u></em>
by use of Charles law formula
that is V1/T1 = V2/T2 where;
V1 = 2.25 l
T1= 298 k
V2= 3.50 l
T2=?
make T2 the subject of the formula T2 =(V2 xT1) /v1
T2= (3.50 l x 298 K) /2.25 L = 463.56 K
