Answer:

Weight reduces

Explanation:

As you continue to move away form the earth to the moon, weight begins to reduce because the acceleration due to gravity reduces.

Weight is the force gravity on a body;

Weight = mass x gravity

Since mass is consistent and does not vary, the weight changes due to differences in gravity on the bodies.

On the moon, the gravity is lower than on the earth.
This also, makes the weight lower on the moon.

Is there massless ness in space?Why?

dangina [55]

If we are comparing two different things to each other on Earth, they are pulled the same by gravity and so the one with more mass weighs more. But in space, where the pull of gravity is very small, something can have almost no weight. It still has matter in it, though, so it still has mass.

An ionic compound has a solubility of 30 g per 100 mL of water at room temperature. A solution containing 70 g of the compound i

Llana [10]

Answer: A. unsaturated.

Explanation:

Unsaturated solution is defined as the solution in which more solute particles can be dissolved in the solvent.

Saturated solution is defined as the solution in which no more solute particles can be dissolved in the solvent.

Supersaturated solution is defined as the solution in which more amount of solute particles is present than the solvent particles.

Given: Solubility = 30g/100ml

If 100 ml can dissolve ionic compound = 30 g

300 ml can dissolve ionic compound = $\frac{30}{100}\times 300=90g$

Thus solubility is 90g/300 ml and dissolved salt is only 70 g , the solution is said to be unsaturated.
