Answer:
C
Explanation:
C because there is more in it than the rest of the idems
The amount (in pounds) the gasoline tank will hold when full is 153.76 lb
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
<h3>How to convert gallon to milliliters </h3>
1 gallon = 3785.412 mL
Therefore,
25 gallon = 25 × 3785.412
25 gallon = 94635.3 mL
<h3>How to determine the mass </h3>
- Density = 0.737 g/mL
- Volume = 94635.3 mL
- Mass =?
Mass = Density × Volume
Mass = 0.737 × 94635.3
Mass = 69746.2161 g
<h3>How to convert grams to pounds </h3>
453.592 g = 1 lb
Therefore,
69746.2161 g = 69746.2161 / 453.592
69746.2161 g = 153.76 lb

1. Energy can neither be created or destroyed.
2. Conduction. Putting a pot of water on a hot burner. Convection. Putting your wet shoes over an air vent to dry them quicker. Radiation. Sitting in front of the fire to warm your hands up.
3. renewable sources can be used again and again, but non renewable sources cannot.
4. I would recommend solar energy. I think solar energy should be considered because solar energy can be reused, and also because they can use it to power their houses and they wouldn't need fossil fuels to do so.
5. Turn off the lights and open the windows during the day and if something is left plugged into the wall and it is not being used, unplug it.

Answer:a) 11.34 g of ethane 
can be formed
b) 
is the limiting reagent
c) 3.44 g of the excess reagent remains after the reaction is complete
Explanation:
To calculate the moles :
1. 
2. 
According to stoichiometry :
1 mole of require 1 mole of 
Thus 0.378 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
moles of left = (2.10-0.378) = 1.72 moles
mass of left=
According to stoichiometry :
As 1 mole of give = 1 mole of 
Thus 0.378 moles of give = of
Mass of 
Thus 11.34 g of ethane is formed.
Answer:
it is endothermic change ..........
