Alex17521 [72]

The Number of moles required for MTBE is 2 as per molarity based chemistry theories.

  1. A flammable liquid with a distinct, unpleasant smell is called methyl tert-butyl ether (MTBE).
  2. Since the 1980s, it has been added to unleaded gasoline as a fuel additive to promote more effective burning.
  3. It is created by mixing chemicals like isobutylene and methanol. Gallstones can be removed with MTBE as well.
  4. In this type of treatment, surgically inserted special tubes are used to deliver MTBE directly to the gall bladders of the patients.
  5. Methyl tert-butyl ether is a colorless liquid with a distinct anesthetic-like smell. Vapors are narcotic and heavier than air. 131 °F boiling point. 18 °F is the flash point.
  6. It is miscible in water and less dense than water. Boosts the octane of gasoline.
  7. Therefore it has 2 moles of oxygen.

Silver nitrate reacts with calcium to make calcium nitrate and silver. The reaction is exothermic and produces 18.7 kJ/mol of en
denis-greek [22]

Answer:

1.63 kilo Joules of energy will be produced when 14.8 g of silver nitrate react.

Explanation:

AgNO_3+Ca\rightarrow Ag+CaNO_3,\Delta H_{rxn}=-18.7 kJ/mol

Mass of silver nitrate = 14.8 g

Moles of silver nitrate = \frac{14.8 g}{170 g/mol}=0.08706 mol

According to reaction, when 1 mole of silver nitrate reacts with 1 mole of calcium it gives 18.7 kJ of heat.

Then amount of heat released when 0.08706 moles of silver nitrate reacts :

0.08706\times 18.7 kJ=1.628 kJ\approx 1.63 kJ

1.63 kilo Joules of energy will be produced when 14.8 g of silver nitrate react.

The following balanced equation shows the formation of ethane (C2H6).
Pavlova-9 [17]

Answer:

We need 27.56 moles hydrogen to produce 13.78 mol of ethane. (option 3)

Explanation:

Step 1: Data given

Moles ethane produced = 13.78 moles

Step 2: The balanced equation

C2H2 + 2H2 → C2H6

Step 3: Calculate moles of hydrogen

For 1 mol acetylene (C2H2) we need 2 moles hydrogen (H2) to produce 1 mol of ethane (C2H6)

For 13.78 moles ethane produced we need 2*13.78 = 27.56 moles hydrogen (H2)

We need 27.56 moles hydrogen to produce 13.78 mol of ethane. (option 3)
