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

Answer:
pollination is the proces called
Answer:
Explanation:
This question seeks to test the knowledge of separation techniques.
From the narration in the question, the first separation to be done is the removal of Iron fillings by the use of magnet (magnetic separation). Since Iron is magnetic, the iron fillings will be attracted by the magnet hence removing the iron fillings from the mixture.
The second constituent to be removed will be the copper pieces by the use of a sieve (sieving). Copper pieces have relatively larger sizes than sand and common salt, hence a sieve (which separates particles based on size) can be used to remove the copper pieces from the mixture.
What will be left in the mixture after the processes above will be salt and water. This mixture will have to be dissolved in water; the salt will dissolve in water while the sand will not. After which, filtration will be done to remove the sand which will be collected on the filter paper as filtride and the salt solution will pass through the filter paper as filtrate.
The salt solution can then be evaporated to dryness to retrieve the solid salt from the solution.
The amount of salt in the mixture can then be measured using a weighing balance.
Some of safety measures to be taken during the course of this experiment includes performing the experiment in an airtight and controlled environment. Lab coat and hand gloves should be worn during the course of the experiment. The evaporation to dryness should not be done close to an inflammable material/substance
Answer:2 AL + FEN2 = 2 ALN + FE
Explanation: AL might be an improperly capitalized: Al. One of your compounds is AL (A and L). Did you mean Al (aluminum)?
FEN2 might be an improperly capitalized: FeN2. ALN might be an improperly capitalized: AlN
FE might be an improperly capitalized: Fe
Explanation:
Speed and velocity are both used to describe the motion of a body. But there are differences between the two terms.
- Velocity is the rate of change of displacement with time. It is mathematically expressed below:
Velocity = 
The unit of velocity is m/s or km/hr.
Velocity is a vector quantity that shows magnitude and direction.
- Speed is the rate of change of distance with time. It is concerned with the total length of path a body moves.
Speed = 
It has the same unit as velocity
It is a scalar quantity that has only magnitude.
