See the answer below
Explanation:
<em>Aqueous solution of copper II nitrate contains solute of copper II nitrate dissolved in water</em>. The equation for the reaction is as below:
+ 
--> 
Hence, the solute chemical is copper II nitrate while the solvent is water.
Chemical formula of copper II nitrate - 
Chemical formula of water - 
Answer:Use the Law of Sines to solve the triangle ABC if it exists: a) A= 68.41°, B = 54.23”, a = 12.75 ft. b = b = b = a sub ź111347.
Explanation:
Answer:
the vapor pressure of this solution would increase if some of the water were allowed to evaporate
Endothermic means it absorb energy from surrounding and its sign is positive so when it absorb this energy the flask or the container become colder
Answer:
The answer to your question is 245.9 g of Fe₂O₃
Explanation:
Data
grams of Fe₂O₃ = ?
grams of Fe = 172 g
Balanced chemical reaction
Fe₂O₃ + 3H₂ ⇒ 2Fe + 3H₂O
Process
1.- Calculate the molar mass of of Iron Oxide and Iron
Fe₂O₃ = (2 x 56) + (3 x 16) = 112 + 48 = 160 g
2Fe = 2 x 56 = 112 g
2.- Use proportions and cross multiplication to solve this problem
160 g of Fe₂O₃ --------------- 112 g of Fe
x ---------------- 172 g of Fe
x = (172 x 160)/112
x = 27520/112
x = 245.9 g of Fe₂O₃
