Answer:
No, bubbles would not be produced.
Explanation:
Catalase is an enzyme that catalyses the decomposition of hydrogen peroxide into water (H2O) and oxygen gas (O2). Since oxygen (O2) is a gas, it is physically noticeable as BUBBLES. However, catalase as an enzyme is substrate-specific i.e. it solely acts/breaks down on hydrogen peroxide.
Hence, If one were to add glucose to catalase instead of hydrogen peroxide, oxygen gas observed as BUBBLES will not be produced because catalase will not act on glucose.

How many moles of Fe2+ are there in a 2.0g sample that is 80% by mass of FeCl2?
The number of moles of [tex]Fe^{2+}[/tex] in the [tex]2.0g[/tex] sample of [tex]FeCl_{2}[/tex] is [tex]0.0157[/tex] moles.
The following points should be noted about the number of moles:
The number of moles of any substance can be calculated using the mass and molar mass of the substance. [tex]n = \frac{mass}{molarmass}[/tex], where n is the number of moles.Mass of the sample given as [tex]2.0g[/tex] and the molar mass of the sample as [tex]126.75g/mol[/tex].
Therefore, the number of moles of [tex]Fe^{2+}[/tex]is obtained by dividing the mass by the molar mass.
Hence the number of moles is obtained as [tex]0.0175[/tex] moles.

what is the dilution factor if you add a 0.1ml aliquot of a specimen to 9.9 dilutent
The dilution factor : 100
Further explanationThe dilution factor(DF) : ratio of concentration of stock solution and diluted solution or ratio of the volume of final solution to the initial volume from stock solution
From equation of dilution :
M₁V₁=M₂V₂
[tex]\tt DF=\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}[/tex]
Volume of aliquot = 0.1 ml
Volume of diluent = 9.9 ml
So final volume :
[tex]\tt V_f(final~volume)=volume~aliquot+volume~diluent\\\\V_f=0.1+9.9=10~ml[/tex]
The dilution factor (DF) :
[tex]\tt D_f=\dfrac{V_f}{V_i}\\\\D_f=\dfrac{10}{0.1}=100[/tex]

If I change the volume of a solution from 5.00 L to 10.0 L, what was the new
concentration if the original concentration was 4.0 M? Please help me as soon as possible with explanation.
The new concentration = 2 M
Further explanationDilution is a process of decreasing the concentration of a solution by adding a number of solvents
Can be formulated
M₁V₁=M₂V₂
M₁ = Initial Molarity
V₁ = Initial volume
M₂ = Final Molarity (after dilution)
V₂ = Final volume (after dilution)
V₁=5 L
V₂=10 L
M₁=4 M
The new concentration(M₂) :
[tex]\tt M_2=\dfrac{V_1.M_1}{V_2}\\\\M_2=\dfrac{5\times 4}{10}\\\\M_2=2~M[/tex]

Answer:
sulfur
Explanation:
In oxygen family sulfur has yellow color and also having stinky smell. Thus given statements are about sulfur.
It is present in oxygen family.
It has six valance electrons.
Its atomic number is 16.
Its atomic weight is 32 amu.
The electronic configuration of sulfur is given below,
S₁₆ = 1s² 2s² 2p⁶ 3s² 3p⁴
We can see the valance shell is third shell and it have six electrons thus sulfur have six valance electrons. (3s² 3p⁴ )
Sulfur is used in vulcanisation process.
It is used in bleach and also as a preservative for many food.
it is used to making gun powder.

Your car has 1.95 gallons of gasoline (octane, d = 0.6916 g/mL), which reacts with oxygen
according to the balanced reaction below. Your car uses the energy produced by this reaction
at a rate of 115 kJ per second while traveling at a speed of 65 miles per hour. Calculate the
distance (in miles) the car can travel using this amount of octane.
2 C8H18(g) + 25 O2(g) -----> 16 CO2(g) + 18 H2O(g) ΔHrxn = -10,900 kJ
Answer:
38.3 miles
Explanation:
First, we convert 1.95 gallons to mililiters:
1.95 gallons * [tex]\frac{3.785 L}{1gallon}*\frac{1000mL}{1 L}[/tex]= 7380.75 mLThen we calculate how many grams of octane are available for the reaction, using its density:
0.6916 g/mL * 7380.75 mL = 5104.53 g C₈H₁₈Now we convert octane grams into octane moles, using its molar mass:
5104.53 g C₈H₁₈ ÷ 114 g/mol = 44.78 mol C₈H₁₈Then we calculate how many kJ are produced from the combustion of 44.78 mol C₈H₁₈, if 2 moles produce 10900 kJ:
44.78 mol * 10900 kJ / 2 mol = 244032 kJWe calculate how many seconds is the car available to keep going, if it spends 115 kJ per second:
244032 kJ * 1 s / 115 kJ = 2122.02 sWe convert seconds to hours:
2122.02 / 3600 = 0.59 hoursFinally we calculate the distance:
65 mi/hour * 0.59 hour = 38.3 mi
