For the purpose we will use solution dilution equation:
c1V1=c2V2
Where, c1 - concentration of stock solution; V1 - volume of stock solution needed to make the new solution; c2 - final concentration of new solution; V2 - final volume of new solution.
c1 = 100%
c2 = 75%
V1 = 1 gal
V2 = ?
When we plug values into the equation, we get following:
100 x 1 = 75 x V2
V2= 100/75 = 1.33 gal
Now we can determine the necessary volume of water:
V(water)= V2 - V1 = 1.33 - 1 = 0.33 gal water should be added
0.7(Btu/lbmoF) 2.9<span>(kJ/kg K)</span>
The slope would be 8.92g/cm^3.
<em>D = m/V</em>
<em>m = DV
</em>
The equation for a straight line is
<em>y</em> = m<em>x</em> +b, where m is the slope and b is the y-intercept. We have
<em>m</em> = D<em>V</em> + 0
Thus, a plot of <em>m</em> vs <em>V</em> will give a straight line with a slope of <em>D</em> and a
<em>y</em>-intercept at the origin.
Slope = <em>D</em> = 8.92g/cm^3
C. NO2 is covalent. Hope this helps!

True.
Explanation:
Organic compounds can be found pure, but generally, they are in mixtures, such as the petroleum, so it is possible to the compound received be impure;
Organic compounds can be found in the three states: solid, liquid or gas. The state will depend on the molecular forces in it and its molar mass. For example, gasoline is liquid in the ambient temperature, natural gas is a gas, and the glucose is solid;
The main characteristic of the organic compounds is the presence of C and H, the other elements can or can't be in the structure: O, N, halogens, and S;
Because of the carbon can form chains, there are several million possible known organic compounds;
The spectroscopic would give some results such as composition, molar mass, and diffraction, and with these results, it would be possible to identify some chemical properties and the tests needs more identification.
