<em>Answer:</em>
- At 60 centigrade, the kinetic energy of the substance will be greatest.
<em>Explanation:</em>
As we know, the kinetic energy of substance is directly proportional to Temperature.
The total Kinetic energy can be calculated as follow
K.E = 3/2 n.R.T
From the equations, it is cleared that Temperature is directly proportional to temperature.

</span>The balanced reaction is:<span>
Mg (s) + 2HCl (aq)
--> MgCl 2 (aq) + H 2 (g)
We
are given the amount hydrochloric acid to be used for the reaction. This will
be the starting point of the calculation.
40.0 g
HCl ( 1 mol HCl / 36.46 g HCl)
(1 mol H2 / 2 mol HCl) (2.02 g H2 / 1 mol H2) = 1.11 g H2</span>
Answer:
The answer is
<h2>22 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of liquid = 44 g
volume = 2 mL
The density of the liquid is

We have the final answer as
<h3>22 g/mL</h3>
Hope this helps you
Answer and Explanation:
a. The equation of K of this reaction is shown below:-
3 A + 5 B + 4 C↔5 D + 7 E + F

b. The moles of compound F is shown below:-
3 A + 5 B + 4 C↔5 D + 7 E + F
2 moles
Now, the mole of produced is

Now, we will the value of c by using the above equation

After solving the above equation we will get
0.5 moles
