Answer:
6116g
Explanation:
2SO2(g) + O2(g) + 2H2O(ℓ) −→ 2H2SO4(ℓ)
We want to find the mass in grams of SO2 that is needed to react with 1527 g of O2. First we must convert the grams of O2 to moles of O2 then to moles of SO2 and then to grams of SO2
So first lets find the molar mass of O2
The mass of oxygen according to a periodic table is 15.999
Using this the mass of O2 would be 15.999(2) = 31.988g
Next we need to identify the mole ratio of O2 to SO2
Looking at the equation for 1 mole of O2 there are two moles of SO2
Next we need to find the molar mass of SO2
Again the mass of oxygen is 15.999g and the mass of Sulfur is 32.066
So the mass of SO2 would be 15.999(2) + 32.066 = 64.064g
Now that we have found all the needed conversions :
1 mol O2 = 31.988g 1 mol O2 = 2 mol SO21 mol SO2 = 64.064gWe can now use dimensional analysis to calculate the answer.
Kindly check the attached image to see the table. ( sorry if its a bit blurry )
Explanation : The conversions are used to cancel out the units to get to the final unit which is gSO2.
Once the units are cancelled out except for the gSO2 we mutliply and divide based off of what the table says to do.
Here first we divide 1527 by 31.988. We than multiply by 2. Finally we multiply by 64.064 to get the final answer which is 6116gSO2

Answers
The woman that has 7.9 * 10-3 mol of hemoglobin in her blood has 509.20 grams of hemoglobin in her blood.
How to calculate mass?The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass. That is;
mass = no. of moles × molar mass
According to this question, a woman has 7.9 × 10-³ mol of hemoglobin in her blood. The mass of hemoglobin in her blood is as follows:
mass = 7.9 × 10-³ × 64,456 g/mol
mass = 509.2grams.
Therefore, the woman that has 7.9 * 10-3 mol of hemoglobin in her blood has 509.20 grams of hemoglobin in her blood.

If 70.0g of manganese (IV) fluoride reacts with 70.0g ammonium sulfide, which reactant is
the limiting reactant and how many grams of the excess reactant is left over?
MnF_4(aq)+2(NH_4)_2S(aq)-> MnS_2(s)+4NH_4F(aq)
Answers
The limiting reactant would be the ammonium sulfide and the amount of the excess manganese (IV) fluoride would be 1.96 grams
Limiting reactantsFrom the equation of the reaction:
[tex]MnF_4(aq)+2(NH_4)_2S(aq)- > MnS_2(s)+4NH_4F(aq)[/tex]
The mole ratio of [tex]MnF_4[/tex] to [tex](NH_4)_2S[/tex] is 1:2
Mole of 70 g [tex]MnF_4[/tex] = 70/130.93
= 0.53 moles
Mole of 70 g [tex](NH_4)_2S[/tex] = 70/68.154
= 1.03 moles
Equivalent mole of [tex](NH_4)_2S[/tex] = 0.53 x 2
= 1.06 moles
Thus, [tex](NH_4)_2S[/tex] seems to be limiting while [tex]MnF_4[/tex] is in excess.
Excess [tex]MnF_4[/tex] = 0.53 - 1.03/2
= 0.015 mole
Mass of 0.015 mole [tex]MnF_4[/tex] = 0.015 x 130.93
= 1.96 grams

If 16.4 grams of copper (II) bromide react with 22.7 grams of sodium chloride, how many grams of sodium bromide are formed?
Answers
The amount of sodium bromide that would be formed from the reaction will be 7.5524 grams
Stoichiometric calculationLooking at the equation of the reaction:
[tex]CuBr_2 + 2NaCl --- > CuCl_2 + 2NaBr[/tex]
The mole ratio of CuBr2 and NaCl is 1:2.
Mole of 16.4 grams of CuBr2 = 16.4/223.37
= 0.0734 moles
Mole of 22.7 grams of NaCl = 22.7/58.44
= 0.3884 moles
Equivalent mole of NaCl = 0.1468 moles
Thus, NaCl is in excess while CuBr2 is limiting.
Mole ratio of CuBr2 and NaBr = 1:1
Mass of 0.0734 mole NaBr = 0.0734 x 102.894
= 7.5524 grams

Based on the titration curve, the titration is of a strong acid strong base and pH at equivalence point is 7.
What is equivalence point?The equivalence point in an acid-base titration is the point at which equal amount of acid and base have reacted.
The equivalence point in a strong acid-strong base titration is at pH 7.
In a weak acid-strong base titration, the pH is greater than 7 at the equivalence point.
In a weak base-strong acid titration, the pH is less than 7 at the equivalence point.

What is a mass number (A)?
Answers
Answer:
The mass number in a nucleus is the combined number of protons and neutrons, so it's protons and neutrons, and A symbolizes it. So A is the number of masses, which is equal to the number of protons, that is the number of atoms that we symbolized by Z, plus the number of neutrons.
The mass number, also called atomic mass number or nucleon number, is the total number of protons and neutrons in an atomic nucleus. It is approximately equal to the atomic mass of the atom expressed in atomic mass units.
