Answer:
Both technicians A and B are right
Explanation:
A mass flow sensor (MAF sensor) is defined as a sensor which is normally used to estimate the mass flow rate of air that flows into an internal combustion engine. The estimated parameter is used at the engine control unit to ensure that the actual mass of fuel is supplied to the engine. A MAF sensor can also measures the density and amount of air flowing into the engine. In addition, a hot wire MAF sensor uses the electronics in the sensor itself to heat a wire 70°C above the temperature of the air entering the engine. Therefore, both technicians A and B are right.
Answer:
Q1) Distillation relies on evaporation to purify water
Explanation:
contaminated water is heated to form steam. inorganic compounds and large non-volatile organic molecules do not evaporate with the water and are left behind. The steam then cools and condenses to form purified water
Answer:
Structural formula shows the atoms and bondsin an organic compound.
Explanation:
Structural formula of methane shows
1 Carbon atom is singly bonded to 4 hydrogen atoms.

Answer:
1.27 moles (3 s.f.)
Explanation:
Mole ratio of water: C6H14
= 14:2
= 7:1
This means that to produce 7 moles of water, 1 mole of C6H14 is needed. Or 1/7 mole of C6H14 is needed to produce 1 mole of water. So if you need 8.86 moles of water, 8.86(1/7) moles of C6H14 is needed.
For 8.86mol of water, moles of C6H14 needed
= 8.86/7
= 1.27 moles (3 s.f.)
