A student finds the mass of an empty 50-mL beaker to be 36.52 g. She then uses a 25.0- mL volumetric pipet to transfer a sample of an organic liquid to the beaker. The beaker and its contents now have a mass of 53.25 g. what is the density of the liquid?
Answers
Answer:
density = 0.669 but see below.
Explanation:
Mass of Beaker and the liquid = 53.25
Mass of just the beaker = 36.52 Subtract
Mass of the liquid 16.73
Density = mass / volume
mass = 16.73
volume = 25.0 mL
You have to assume that the pipette was filled right to the top.
Density = 16.73 / 25.0 = 0.6692 grams / mL
Since this only has 3 places of accuracy, the answer should be 0.669

Calculate the mass of chromium produced from 50g of Cr2O3.
Answers
Answer: 34 gram of chromium produced from 50g of [tex]Cr_2O_3[/tex]
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Cr_2O_3=\frac{50g}{152g/mol}=0.33moles[/tex]
The decomposition of [tex]Cr_2O_3[/tex] follows the equation :
[tex]2Cr_2O_3\rightarrow 4Cr+3O_2[/tex]
According to stoichiometry :
2 moles of [tex]Cr_2O_3[/tex] produce = 4 moles of [tex]Cr[/tex]
Thus 0.33 moles of [tex]Cr_2O_3[/tex] will produce=[tex]\frac{4}{2}\times 0.33=0.66moles[/tex] of [tex]Cr[/tex]
Mass of [tex]Cr=moles\times {\text {Molar mass}}=0.66moles\times 52g/mol=34g[/tex]
Thus 34 gram of chromium produced from 50g of [tex]Cr_2O_3[/tex]

Consider this reaction mechanism:
Step 1: C4H9Br C4H9+ + Br- (slow)
Step 2: C4H9+ + OH- C4H9OH (fast)
Which rate law is consistent with the mechanism?
Answers
The slow step is always the rate-determining step. In the slow step, C4H9Br is the only reactant and has a coefficient of 1, so it is first order in the rate law.

3. Consider the reaction of methane, CH4, burning in the presence of oxygen at constant pressure. Given the following equation, how much heat could be obtained by the combustion of 8.0 grams CH4? Given the thermochemical equation: CH4(g)+2O2→CO2(g)+2H2O(l); ΔH0=890.3kJ;
Answers
Answer: 445.15 kJ of heat could be obtained by the combustion of 8.0 grams [tex]CH_4[/tex]
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} CH_4=\frac{8.0g}{16.04g/mol}=0.50moles[/tex]
The given thermochemical equation is:
[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)[/tex] [tex]\Delta H=890.3kJ[/tex]
According to stoichiometry :
1 mole of [tex]CH_4[/tex] on combustion produce heat = 890.3 kJ
Thus 0.50 moles of [tex]CH_4[/tex] on combustion produce heat =[tex]\frac{890.3}{1}\times 0.50=445.15kJ[/tex]
Thus 445.15 kJ of heat could be obtained by the combustion of 8.0 grams [tex]CH_4[/tex]

What is the [SO32-) in the 0.080 M H2SO3 .080 M Solution?
Answers
Answer:
0.080 M
Explanation:
From the question given above, the following data were obtained:
Concentration of H₂SO₃ = 0.080 M
Concentration of SO₃²¯ =…?
The concentration of SO₃²¯, can be obtained as follow:
H₂SO₃ (aq) <==> 2H⁺ (aq) + SO₃²¯ (aq)
From the balanced equation for above,
1 mole of H₂SO₃ produced 1 mole of SO₃²¯.
Therefore, 0.080 M H₂SO₃ will also produce 0.080 M SO₃²¯.
Thus, the concentration of SO₃²¯ is 0.080 M

100.0g Ca3(PO4)2
Answers
Answer:
0.322 moles
Explanation:
Given Mass, m = 100 g
The molar mass of Ca₃(PO₄)₂
Ca₃(PO₄)₂ = (3 x 40.08) + (2 x 30.97) + (8 x 16.00)
M = 310.18 g/mol
Let there are n number of moles,
n = given mass/ molar mass
[tex]n=\dfrac{100 }{310.18 }\\\\n=0.322\ mol[/tex]
So, there are 0.322 moles.

“anodization” followed by “electroplating”
“electroplating” followed by “electrometallurgy”
Answers
Answer: A. “electrometallurgy” followed by “electroplating”
Explanation:
Right on edge :)
Answer:
It would be A. “electrometallurgy” followed by “electroplating”
Explanation:
Electrometallurgy is the reduction of metals from compounds to obtain the pure form of metal using electrolysis. In other words, a process in which ores are converted into the pure form of that certain metal through electrolysis.
Electroplating is a process of depositing a thin layer of metal onto an object in an electrolytic cell for strengthening or decorative purposes.
Also in case you are wondering, anodization is a process that makes the surface of metals resistant to corrosion, making the answers containing this process incorrect.
