There are materials embedded in rocks forming it shape and properties
Answer:
D) single replacement
Explanation:
Given reaction:
Mg + 2HCl → MgCl₂ + H₂
The reaction shown above is a single displacement reaction.
In a single displacement reaction, a more reactive atom displaces another from a given compound.
The comparison here is between Mg and H.
On the activity series, Mg is higher and more reactive, it will displace H from the solution of HCl. This
This reaction type is called a single replacement reaction.
I think that it is true to the bone
For the answer to the question above,
322Joules of heat energy is added to the system (gold bar) while no work is done on the gold bar, this is an isochoric/isovolumetric process, thus
<span>ΔU = 322J + 0 </span>
<span>=322J </span>
<span>Therefore the internal energy increase by <u>322J
