The answer is Doppler Radar. Hope this helps!
The molarity of HCl is calculated as below
find the moles of mg used
moles = mass /molar mass
= 2.00g/24 g/mol=0.083 moles
write the reacting equation
Mg(s) +2HCl (aq)= MgCl2(aq) + H2(g)
by use of mole ratio between Mg to HCl which is 1 :2 the moles of HCl is therefore
= 0.083 x2 =0.166 moles
molarity of HCl = moles of HCl/ volume in dm^3
that is 0.166/50 x1000= 3.3 M of HCl
4.24 L i am taking the test rn and I am almost positive that 4.24 is the answer, hope this helps!
Answer:
The transfer of energy between the two substances stops when the two substances are at equilibrium. If the two substances were exchanging heat energy, then the transfer of energy stops when both are at the same temperatures and the net flow of heat energy between the two become zero.
Explanation:
A system is said to be in equilibrium when the forward forces are equal to the reverse forces and the equilibrium quotient is the same as the equilibrium constant. No further work is being done. Also, the entropy is at its highest and Gibbs free energy at its lowest.

The temperature dropped because B. energy was absorbed during the chemical reaction.
If energy was released, the temperature would rise. If there was no energy input, the temperature would stay the same. Since temperature dropped, it means that energy was absorbed.
