Reika [66]3 years ago
3 0

The rocket pushes the exhaust gases backward and there is an "equal and opposite reaction" that pushes the rocket forward.

Answer: Option (b)

<u>Explanation:</u>

Rocket is one of the propulsive unit functions similar to air-filled balloons and it works on the principle of newton thirds law of motion.

This law states that for every action there will be an equal and opposite reaction.

The fuel is burned inside the rocket and it releases the exhaust gas and these gases create an impact of force that propels the rocket into space.

Answer:

Explanation:

it's worth pointing out that the terms solute and solvent do not really apply here because sulfuric acid is miscible in water, meaning that the two liquids can be mixed in all proportions to form a homogeneous mixture, i.e. a solution.

Calculate the mass percent of calcium chloride in 8.87 g of calcium chloride in 65.1 g of water
zhannawk [14.2K]

Answer:

11.99 % ≅ 12.0%.

Explanation:

∵ mass % = [mass of solute/mass of solution] x 100.

mass of solute (CaCl₂) = 8.87 g & mass of solution = 8.87 g + 65.1 g = 73.97 g.

<em>∴ mass % of (CaCl₂) = [mass of solute/mass of solution] x 100 </em>= ( 8.87 g/ 73.97 g) x 100 = <em>11.99 % ≅ 12.0%.</em>
