Answer:
Cr(NO₃)₂(s) → Cr⁺²(aq) + NO₃⁻(aq)
Explanation:
A strong electrolyte is a substance that dissolves in water, dissociating in its ions, and making the solution an electric conductor. The conduction will happen because of the presence of the ions. The dissociation will be complete and irreversible.
The chromium (II) nitrate is formed by the cation chromium (II), Cr⁺², and the anion nitrate, NO₃⁻, so it is the compound Cr(NO₃)₂.
Cr(NO₃)₂(s) → Cr⁺²(aq) + NO₃⁻(aq)
Answer:
as beaker is open so
As ψof solution is lower than the root tissue so water will move out of the root to the solution
Explanation:
Thus 174 protons would make at most 6 copper atoms. However, it would take 174 extra electrons (29 per atom) and even more neutrons than that to construct neutral copper atoms with stable nuclei.
Answer:
2.4x10² kcal
Explanation:
As the serving of fish contains 50g of protein that is 4.0kcal/g:
50g × (4.0kcal/g) = <em>200kcal</em>
<em> </em>
And in 4g of fat that is 9.1kcal/g:
4g × (9.1kcal/g) = <em>36.4kcal</em>
<em />
That means the kcal of the serving are:
200kcal + 36.4kcal = 236.4kcal
In 2 significant figures: <em>2.4x10² kcal</em>
<em></em>
I hope it helps!
