Oh, no! You just spilled 85.00 mL of 1.500 M sulfuric acid on your lab bench and need to clean it up immediately! Right next to
vredina [299]

Explanation:

We will balance equation which describes the reaction between sulfuric acid and sodium bicarbonate: as follows.

   H_2SO_4(aq) + 2NaHCO_3(s) \rightarrow Na2SO_4(aq) + 2H_2O(l) + 2CO_2(g)

Next we will calculate how many moles of H_2SO_4 are present in 85.00 mL of 1.500 M sulfuric acid.

As,       Molarity = \frac{\text{moles of solute}}{\text{liters of solution&#10;}}

            1.500 M = \frac{n}{0.08500 L&#10;}

                    n = 0.1275 mol H_2SO_4

Now set up and solve a stoichiometric conversion from moles of H_2SO_4  to grams of NaHCO_3. As, the molar mass of NaHCO_3 is 84.01 g/mol.

 0.1275 mol H_2SO_4 \times (\frac{2 mol NaHCO_3}{1 mol H_2SO_4}) \times (\frac{84.01 g NaHCO_3}{1 mol NaHCO_3})

                 = 21.42 g NaHCO_3

So unfortunately, 15.00 grams of sodium bicarbonate will "not" be sufficient to completely neutralize the acid. You would need an additional 6.42 grams to complete the task.

How many grams of C3H8 would be needed to produce 6.39 grams of CO2?
just olya [345]

Answer:

2.13g

Explanation:

Atomic mass of CO2 =  12 + 32 = 44g/Mol

Atomic mass of C3H8 = 36 + 8 = 44g/Mol

Reaction

C3H8 + 5O2 --> 3CO2 + 4H2O

3CO2 = 6.39g

Required C3H8 = (6.39/(44 x 3)) x 44 = 2.13g

How many atoms are in 73.9g of potassium oxide
denis-greek [22]

Answer: 4.69(10)^{23} atoms

Explanation:

Firstly, we have to find the Molecular mass of potassium oxide (K_{2}0):

K atomic mass: 39 u

O atomic mass: 16 u

K_{2}O molecular mass: 39(2) g/mol+16g/mol=94 g/mol

This means that in 1 mole of K_{2}O there are 94 g and we need to find how many moles there are in 73.9 g K_{2}O:

1 mole of K_{2}O-----94 g of K_{2}O

X-----73.9 g of K_{2}O

X=\frac{(73.9 g)(1 mole)}{94 g}

X=0.78 mole This is the quantity of moles in 73.9 g of potassium oxide

Now we can calculate the number of atoms in 73.9 g of potassium oxide by the following relation:

N_{atoms}=(X)(N_{A})

Where:

N_{atoms} is the number of atoms in 73.9g of potassium oxide

N_{A}=6.0221(10)^{23}/mol is the Avogadro's number, which is determined by the number of particles (or atoms) in a mole.

Then:

N_{atoms}=(0.78 mole)(6.0221(10)^{23}/mol)

N_{atoms}=4.69(10)^{23} atoms This is the quantity of atoms in 73.9g of potassium oxide
