Meso−2,3−butanediol is the product of the top reaction
Answer:
2Al + 6HBr → 2AlBr₃ + 3H₂
Explanation:
2Al + 6HBr → 2AlBr₃ + 3H₂
2 Al in reactant side
2 Al in product side
6 Br in reactant side
6 (2x3) Br in reactant side
6 H in reactant side
6 H in product side (3x2)
An empirical formula is a molecular formula D. reduced to the ratio of atoms involved.
An empirical formula has simplefied ratios, which makes it easier to work with. However, the accuracy is not that good
hope this helps
Answer:
aluminum oxide will be produced from the complete reaction of 1.87L of oxygen gas at 793.0mmHg and 28.0 Celsius. answer: 5.36g
Explanation:
Answer:
a) 742.1 mm Hg O2
b) 0.4434 g O2
c) 0.01386 mol O2
Explanation:
<u>Step 1:</u> Data given
Mass of the sample = 3.6349 grams
volume of oxygen = 346.2 mL
Temperature = 23.6 °C
atmospheric pressure = 763.4 mmHg
<em><u>Step 2:</u></em><em> </em><em>What is the partial pressure of the oxygen? </em>
<em><u /></em>
763.4 mmHg - 21.3 mmHg = 742.1 mm Hg O2
<em>b. What mass of oxygen was liberated?</em>
All of the mass lost by the reactants was due to oxygen being liberated.
(3.6349 g) - ( 3.1915 g) = 0.4434 g O2
<em>c. How many moles of oxygen were produced?</em>
(0.4434 g O2) / (32 g O2/mol) = 0.01386 mol O2
