Answer: 21.5kg in grams is 21,500 grams
21.5kg in mg is 215,000,00
Explanation:
MgCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MgCl2 that dissolves.
MgCl2(s) --> Mg+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.87 mol MgCl2/1L × 2 mol Cl⁻ / 1 mol MgCl2 = 1.7 M
The answer to this question is [Cl⁻] = 1.7 M
NaCl is correct answer of your question
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.
