Answer:
1 and 2 only
Explanation: These will make a bad impact on water.
Answer:
Factors affecting a system in equilibrium are;
- concentration
- temperature
- pressure
Explanation:
A chemical equilibrium occurs when there is a proportion in mixtures of reactants and products.
For concentration, where some of the reactants are removed from an equilibrium reaction, the contents in the product side will be unbalanced thus the system will not be equilibrium and according to the Le Chatelier's principle, a system will shift in a manner to return balance in the reaction.
In temperature, in endothermic reactions, energy is considered as a reactant where as in exothermic reactions, energy is considered as a product.In exothermic reactions increase in temperature increases the reaction causing unbalanced reaction. A decrease in temperature causes a backward reaction which is endothermic
Increase in pressure causes the equilibrium to shift to the side of reaction with fewer moles of the reacting gas, where as a decrease in pressure forces the equilibrium to shift to the side of reaction with more moles of gas.
Answer:
See explanation.
Explanation:
Hello!
In this case, we can proceed as follows:
1. Here, the undergoing chemical reaction is:
Thus, the moles and mass of water turn out:
2. Here, the undergoing chemical reaction is:
So the required moles of HCl and the yielded of water are:
3. Here, the undergoing chemical reaction is:
Now, we apply each mole ratio obtain:
A.
B.
Best regards!
Answer:
The answer to your question is:
a) 36 g of water
Explanation:
MW SO₂ = 32 + 32 = 64 g
MW Br = 80 g
MW H₂O = 18 g
MW HBr = 81 g
MW H₂SO₄ = 98
Balanced reaction:
SO₂ + 2Br + 2H₂O ⇒ 2HBr + H₂SO₄
64g 2(80) 2(18) 2(81) 98
64.1 159.9 161.9 98.1
Rule of three with Br and H2O
160 g ---------------- 36 g
160 ------------------- x
x = 160(36)/160 = 36 g oh water
Magnification is the ability to make small objects seem larger, such as making a microscopic organism visible. Resolution is the ability to distinguish two objects from each other.
