If the sugar makes up 25% of the solution, that means the water makes up 75%, or 3/4, of the solution.
Set up a proportion to solve:

Cross multiply:


Therefore, there are 354 grams of water in the solution.
Answer: Diagram 4
Explanation: Diagram 1 represents a state in which particles are closely packed , thus cannot be a representation of gas.
Diagram 2 represents a state in which particles are loosely packed , thus can be a representation of gas.
Diagram 3 represents a state in which particles are closely packed , thus can be a representation of a solid.
Diagram 4 represents a state in which particles are loosely packed , thus can be a representation of gas. It also represents the particles in ionized form. Particles are existing as ions bearing positive and negative charges.
Answer:
Because of the less reactivity of copper.
Explanation:
As well as being resistant to the elements and thereby less likely to be affected by rainfall, hail, and mildew than other types of roofing, copper is also one of the most fireproof materials available. Copper is also highly resistant to thermal changes and thereby doesn't deteriorate quickly.
Magnesium would also corrode PDQ. Magnesium sheeting would also pose an unacceptably high fire hazard.
The answer would have to be letter b. Energy
