According to Le Chatelier’s principle, if the dynamic equilibrium of a system is disturbed by any change in the conditions of the system then the equilibrium will adjust itself in such a way that new equilibrium moves to counteract the change.
Hence, when the concentration of reactants is doubled in a chemical reaction that was in equilibrium then the equilibrium shifts to the right to favor the formation of products.
Answer:
Ozon prevents us from UV rays of the sun. Ozone hole means that UV rays are entering the Earth. This results in cancer.
Explanation:
Chlorofluorocarbons are causing this
Answer:
1.17 grams of HCl can neutralize 2.7 grams sodium bicarbonate
Explanation:
Step 1: Data given
Mass of sodium bicarbonate = 2.7 grams
Step 2: The balanced equation
HCl + NaHCO3 ⇔ NaCl + H2O + CO2
Step 3: Calculate moles NaHCO3
moles NaHCO3 =2.7 g / 84 g/mol= 0.032 moles
Step 4: Calculate moles HCl
For 1 mol NaHCO3 we need 1 mol HCl
For 0.032 moles NaHCO3 = 0.032 moles HCl
Step 5: Calculate mass HCl
Mass HCl = moles HCl * molar mass HCl
mass HCl = 0.032 * 36.46 g/mol= 1.17 grams
1.17 grams of HCl can neutralize 2.7 grams sodium bicarbonate
