Answer:
Remaining the same
Explanation:
By the Lavoisier's principle the matter can't be created nor destroyed, but always transformed.
It means that in an ecosystem, the matter, and also the energy, is not increasing and not decreasing, the total amount remains the same, but in different forms.
The geometry of the double bond is almost always a cis configuration in natural fatty acids<span>. These molecules </span>do<span> not "stack" very well. The intermolecular interactions are much weaker than </span>saturated <span>molecules. As a result, the melting </span>points<span> are much </span>lower<span> for </span>unsaturated fatty acids<span>.

<span>Ca(NO3)2 + Na2CO3 = CaCO3 + 2NaNO3
Yes a precipitate of Calcium Carbonate is formed since it is insoluble in water.
Mol Wt of Calcium Nitrate is 164. And that of Calcium Carbonate is 100.
One mole of Calcium Nitrate produces one mole of Calcium Carbonate.
i.e. 164 gms will produce 100gms of precipitate
So, 1.74gms of Calcium Carbonate will be obtained from 2.85gms Calcium Nitrate present in the original solution.</span>
C. Sulfur and oxygen (non metals) forms a covalent bond while the magnesium (a metal) will react with both non metals to form an ionic bond
When waters salinity increases it’s freezing point will decrease. This is one of the reasons why people salt the roads after a snow storm.
