Answer:
D) hydrochloric acid.
Explanation:
- The balanced equation for the mentioned reaction is:
<em>Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g),</em>
<em></em>
It is clear that 1.0 moles of Zn react with 2.0 moles of HCl to produce 1.0 moles of ZnCl₂ and 1.0 mole of H₂.
- From stichiometry; Zn reacts with HCl with (1: 2) molar ratio.
<em>∴ 2.0 mol of Zn (the remaining 2.0 mol is in excess) react completely with 4.0 mol of HCl with (1: 2) molar ratio.</em>
<em />
So,
the limiting reactant is HCl and the excess reactant is Zn.
<em>Thus, the right choice is: D) hydrochloric acid.</em>
Answer:
See the answer below, please.
Explanation:
Take as an example a light bulb inside a lamp to illuminate a room. When you plug it in a plug and turn it on, light is generated. More precisely, heat (Joule effect) is produced inside the lamp by its internal filament (conductive material) when it passes through the electrical energy, generated by the friction of the atoms that are inside it when it encounters a resistance.
Answer:
Explanation:
A chemical bond is a lasting attraction between atoms, ions molecules that enables the formation of chemical compound.
Hey there!
The elements in this equation are K, N, O, H, and C.
Let's count how many of each are on each side to see if it is balanced.
K: 2 on the left, 2 on the right.
<em>N: 2 on the left, 4 on the right. </em>
<em>O: 9 on the left, 6 on the right. </em>
<em>H: 2 on the left, 4 on the right. </em>
C: 1 on the left, 1 on the right.
Notice that there are different amounts of N, O, and H on the left side and the right side.
This means that the equation is not balanced.
Hope this helps!
Answer: Newtons
Explanation:
Force equals mass times acceleration. Force is measured in Newtons, N. Mass is measured in kilograms, kg. Acceleration is measured in meters per second squared, m/s2.
