Answer:
83.33ml
Explanation:
Firstly, let's notice that 200ml are equal to 0.2L
M=number of moles of the solute ÷ number of liters. Let's call the number of liter by x:
2.5=x÷0.2
x=2.5×0.2
x=0.5
It means you'll need 0.5 mol of HNO. But your solution have 6 moles per liter, so how much do you need? Divide the moles by 12 to have 0.5, so now you need to divide the liter per 12 too. The liter is equal to 1000ml, so:
1000ml÷12=83.33ml
<span>The balanced chemical ionic equarion of MgS(aq)+CuCl2(aq) = CuS(s)+MgCl2(aq) would be as follows:
</span><span>Mg2+ + S2- + Cu 2+ + 2 Cl- ==> CuS + Mg2+ + 2 Cl-
Therefore, the net equation would be:
</span><span>Cu 2+ + S 2- ===> CuS
</span><span>
Hope this helps.

Answer:
New temperature T2 = 16.59°C Approx
Explanation:
Given:
Old volume V1 = 2.36 L
Old temperature T1 = 27°C
New volume V2 = 1.45 L
Find:
New temperature T2
Computation:
Using Charles's Law;
V1T2 = V2T1
(2.36)(T2) = (1.45)(27)
New temperature T2 = 16.59°C Approx
Answer:
c a reaction that requires energy
Explanation:
because it's moving kind of like a human is being more spontaneous by running and or movement it just sounds spontaneous if you think about energy and if you think about the way it works or away human being moved it's hard to explain but it just makes sense why would it be because it's more ordered that one is definitely the one that don't make sense I just don't think it has nothing to do with what it's trying to ask you this answer just makes sense and has a better understanding
