Week four Task: 20 factors
Resolve these ultimate gasoline legislation issues. Present all work for credit score.
1. A gasoline occupies 250 mL at 739 mmHg. For a gasoline at fixed temperature, decide the quantity of gasoline at 514 mmHg. (1.5 factors)
2. Use the molar quantity of a gasoline, at STP, to find out the variety of moles of CO2 in four.00 L of CO2 gasoline. (1.5 factors)
three. A pattern of nitrogen (N2) has a quantity of 50.zero L at a strain of two ATM. What’s the quantity of gasoline at a strain of 15 atm, if there is no such thing as a change in temperature? (1.5 factors)
four. A zero.6 L canister of Oxygen gasoline has a temperature of 297 Ok accommodates 21 mols of O2 gasoline. What’s the strain of this tank? (1.5 factors)
5. Calculate the strain, in atmospheres, of eight.67 mol CO(g) in a 2.zero L tank at 48 levels C. (1 factors)
6. In line with the Bronstead Lowery acid/base concept, what’s the definition of an acid and a base? (1 factors)
7. In line with the Bronstead Lowery acid/base concept, decide the acids and bases within the following chemical reactions: (1 level every, three factors complete)
HCl + NaOH ⟶ NaCl + H2O
NH4+ + H2O ⇌ H3O+ + NH3

eight. Title the next compounds and determine every of the next as a salt, sturdy acid, weak acid, sturdy base, or weak base. (zero.5 factors every, three factors complete)
a. HCl
b. KBr
c. NH3
d. LiOH
e. CH3COOH
f. Ca(OH)2
9. Rank the next options so as of how acidic they’re from most acidic to least acidic. (1 level)
Resolution A: [H3O+] of 1 x 10-2 M
Resolution B: pH 5
Resolution C: [H3O+] of 1 x 10-11 M
Resolution D: [H3O+] of 1 x 10-7 M
Resolution E: pH 9
10. Predict the merchandise of the reactions beneath and ensure every is balanced: (1.5 factors every, zero.5 factors for stability, zero.5 factors for every product)
HCl + Ca(OH)2 →
HBr + NaOH →
