439.3 g CO2
Explanation:
First find the # of moles of CO2 that results from the combustion of 3.327 mol C3H6:
3.227 mol C3H6 × (6 mol CO2/2 mol C3H6)
= 9.981 mol CO2
Use the molar mass of CO2 to determine the # of grams of CO2:
9.981 mol CO2 x (44.01 g CO2/1 mol CO2)
= 439.3 g CO2

How many moles of hypomanganous acid, H3MnO4, are contained in 22.912 g?
Answers
Answer:
0.188mol
Explanation:
Using the formula as follows:
mole = mass/molar mass
Molar mass of hypomanganous acid, H3MnO4 = 1(3) + 55 + 16(4)
= 3 + 55 + 64
= 122g/mol
Mass of H3MnO4 is given as 22.912 g
Hence;
moles = 22.912 ÷ 122
number of moles = 0.188mol

milk sours because of a chemical reaction that takes place between some of the chemicals that make up the milk. Why does a carton of milk left out on a countertop sour sooner than a carton of milk left in the refidgerator
Answers
Answer: A lower temperature slows down the reaction that causes souring, making the milk last longer in the refrigerator.
Explanation:
Milk is made up of different constituents which includes:
--> water,
--> fat,
--> proteins,
--> lactose (milk sugar) and minerals (salts).
Milk is also considered to be a heterogeneous mixture because of the presence of fat and water which are two immiscible liquid phases that are present.
Milk contains a sugar called lactose. It also contains harmless bacteria called lactobacillus, which uses lactose for energy and creates lactic acid as a by-product. It is the lactic acid which makes milk taste sour. Therefore when milk is kept at a LOWER temperature, these bacteria growths are limited but at a HIGHER temperature such as room temperature, the growth is increased. As they increase in growth, the bacteria makes use of the lactose for energy and creates lactic acid as a by-product as earlier mentioned, leading to the sour taste observed.

How many miles are in 27.4 g of NO2
Answers
Answer:
0.59 moles
Explanation:
Given mass = 27.4 g
Molar mass of NO₂ = 46 g/mol
We need to find the number of moles. We know that,
No of moles = given mass/molar mass
Put all the values,
[tex]n=\dfrac{27.4}{46}\\\\n=0.59[/tex]
Hence, there are 0.59 moles of NO₂ .
A gas at 200 K occupies a volume of 350 ml. What temperature is needed to increase the volume
to 500 mL?
Answers
Answer: Temperature in constant pressure is 286 K
Explanation: If pressure remains constant, then V/T = constant.
V1 = 350 ml and T1 = 200 K and V2 = 500 ml. V1/T1 = V2/T2
and T2 = T1· V2 / V1 = 200 K · 500 ml / 300 ml = 285,7 K

What is the molarity when 25.0 g of the compound NaClO3 is placed in 85.0 mL of solution?
Answers
Answer: Molarity when 25.0 g of the compound [tex]NaClO_{3}[/tex]is placed in 85.0 mL of solution is 294.12 M.
Explanation:
Given: Mass = 25.0 g
Volume = 85.0 mL (1 mL = 0.001 L) = 0.085 L
Molarity is the number of moles of a substance divided by volume in liter.
Hence, molarity of given solution is calculated as follows.
[tex]Molarity = \frac{mass}{Volume (in L)}[/tex]
Substitute the values into above formula as follows.
[tex]Molarity = \frac{mass}{volume (in L)}\\= \frac{25.0 g}{0.085 L}\\= 294.12 M[/tex]
Thus, we can conclude that molarity when 25.0 g of the compound [tex]NaClO_{3}[/tex]is placed in 85.0 mL of solution is 294.12 M.
If the half-cell containing 1.00 M Fe(NO3)2(aq) in galvanic cells Y and Z is replaced with a half-cell containing 5.00 M Fe(NO3)2(aq), what will be the effect on the cell voltage of the two galvanic cells
Answers
The details of the galvanic cells are missing so i have attached it.
Answer:
The voltage will increase in cell Y and decrease in cell Z.
Explanation:
Looking at the reaction, in half cell 3, we see that reduction takes place in galvanic cell Y while oxidation takes place in galvanic cell Z.
In galvanic cell Y, aluminum gains electrons which is reduction while in galvanic cell Z, Copper loses electrons which is oxidation.
Now, electricity involves movement of electrons and where there is a loss of electrons, it means a decrease in electricity and when there is a gain in electrons, it means there is an increase in electricity.
Now, in electricity, Voltage is directly proportional to electric power.
Thus, the higher the voltage, the higher the electric power.
Thus, in galvanic cell Y that undergoes gain in electrons, there will be an increase in voltage while in galvanic cell Z that undergoes loss of electrons, there will be a decrease in voltage.
