To do this, you would first add together the molar mass of all involved elements, to find how many grams are in a mole of Cu(OH)2. Keep in mind, the molar mass is equal to the atomic mass of an element in grams. For example the molar mass of copper (Cu) would be 63.55 (with 2 sig. figs.)
Therefore, now we add together the mass of all elements involved.
Cu: (63.55)+O2(15.99x2=31.98)+H2(1.01x2=2.02)
63.55+31.98+2.02= 97.55g per mole of Cu(OH)2.
Now, divide what we have by how much it takes to get a mole of the stuff.
68.1/97.55= 0.698mol Cu(OH)2
Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water's unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies
Answer:
Volume = 75 inch³
Explanation:
Given data:
Area = 12.5 inch
Height = 6 inch
Volume =?
Solution:
Volume = height × length × width
Volume = Area × height
Now we will put the values in formula;
Volume = 12.5 inch² × 6 inch
Volume = 75 inch³
In a reaction, molecular entity that is formed from the reactants. For example, consider this hypothetical stepwise reaction: A + B → C + D.
Answer:- Solubility of the gas at 759 torr is 0.00753 g/L.
Solution:- From given data, 0.00327 g of gas is soluble in 0.376 L of water at 876 torr.
Solubility of gas at 876 torr pressure is = 0.00327g/0.376L = 0.00869 g/L
Solubility of gases is directly proportional to the pressure. It means, grater is the pressure, more is the solubility of gases.
So, 0.00869/876 = X/759
Where, X is the solubility of the gas at 759 torr.
X = 0.00869(759)/876
X = 0.00753 g/L
