Answer:
The number of mole is 0.04167mole
Explanation:
To convert gram to mole, we need to calculate the molecular weight of the compound
C6H12O6
C - 12
H - 1
O - 16
Molecular weight = 6 * 12 + 1 *12 + 6 * 16
= 72 + 12 + 96
= 180g/mol
To covert gram to mole
Therefore,
= 7.50g/ 180g/mol
= 0.04167 mole of glucose
The correct answer are
identify the positive ion and charge
balance the charges
identify the negative ion and charge
Answer: 0.428%
Explanation: % Error = [(measured - Actual)/Actual]*100%
(93.9g - 93.5 g)/93.5g = 0.428%
Explanation:
Chemical equilibrium is the reaction state where the rate of reactants reacting is equal to rate of products deteriorating.
1. Adding benzoate ions to the mentioned equation will shift the equilibrium towards reactant side making more benzoic acid.
2. Adding NaOH to remove hydrogen ions will make the benzoic acid ionize more and hence shift the equilibrium towards products.
3. Adding benzoic acid more will shift the equilibrium towards products.
4. Increasing the hydrogen ion concentration will shift the equilibrium towards reactant, thereby crystalizing the benzoic acid.
5. Cooling the solution will also shift the equilibrium towards reactant side making effective crystals.
Answer:
A neutralized solution in chemistry refers to the reaction between an acid and base that results in a neutral balance, or a measure of 7 on the pH scale.
