The answer is D. This is because liquids take up the shape of the container they are in, so it is never definite. Where as solids stay the same shape.
Yes because plants are a source of food for some animals
Answer:
d
Explanation:
they either gain valence electrons or share them depending on what elements or compound they are reacting with
The balanced chemical reaction would be:
FeS(s)+2HCl(aq)→FeCl2(s)+H2S(g)
We are given the amount of the reactants to be used for the reaction. We use these amounts. First, we determine the limiting reactant of the reaction. From the data, we can say that FeS is the limiting ad HCl is the excess reactant. We calculate as follows:
Amount of HCl used: 0.240 mol FeS x 2 mol HCl / 1 mol FeS = 0.48 mol HCl
0.646 - 0.48 = 0.166 mol HCl left
