Answer:

Fourth Stroke.

Explanation:

There are four strokes in a car engine

a) Intake stroke: In this stroke the air and fuel is being pumped into the compressor from intake valve.

b) compression stroke: The piston moves upward and the fuel air mixture undergoes compression.

c)combustion stroke: The spark plug generates a spark and the fuel undergoes combustion. The energy produced push the piston backwards or downwards.

d) Exhaust stroke: the exhaust gases like carbon dioxide , water, carbon monoxide etc are forced up by the piston.

Using 25 micromoles, pmoles, of CO2 consumed how many grams of glucose (MW = 180 g/mole) were produced?

Sladkaya [172]

Grams of glucose = 0.7488 mg=748.8 μg

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

6CO₂+6H₂O⇒C₆H₁₂O₆+6O₂

25 micromoles, μmoles, of CO₂ :

moles CO₂ : moles glucose - C₆H₁₂O₆ = 6 : 1, so :

$\tt moles~glucose=\dfrac{1}{6}\times 25\mu~moles=4.16\mu~moles=4.16\times 10^{-6}~moles$

mass of glucose

$\tt mass=mol\times MW\\\\mass=4.16\times 10^{-6}\times 180\\\\mass=7.488\times 10^{-4}g=0.7488~mg=748.8\mu g$

Answer:

C) 0.457

Explanation:

The ratio between O2 and H2O is 1:2 according to the balanced equation. You can find how many moles is O2 by : 5.12/22.4 = 0.22857 ( 1 mole = 22.4 litters)

Moles of H2O will be 0.22857 * 2 = 0.457142.

Therefore answer C)
