Mass of the <span>solvent (H2O) in kg
D = m / V
1.02 = m / 125
m = 1.02 x 125
m = 127.5 g of H2O
127.5 / 1000 => 0.1275 kg
mass of solute in mg:
1000 x ( 1.86 x 10</span>⁻⁵ ) = 0.0186 mg
<span>
ppm = mass of solute in mg / mass of solvent in kg
ppm = 0.0186 / </span><span>0.1275
</span><span>
= 0.1458 ppm
hope this helps!

A blue whale will have the largest Schwarzschild radius, as it has larger mass than the other. Thus option A is correct.
<h3>
What is Schwarzschild radius?</h3>
Schwarzschild radius is defined as the radius below which the gravitational pull between a body's particles causes it to collapse gravitationally.
It can also be defined as the radius of a collapsing astronomical object at which gravitational forces necessitate an escape velocity greater than the speed of light, resulting in a black hole.
The Schwarzschild radius is solely determined by the object's mass, hence the larger the mass, the larger the Schwarzschild radius.
Thus. a blue whale will have the largest Schwarzschild radius, as it has larger mass than the other. Thus option A is correct.

CH4 + O2 -> H2O + CO2
Then balance:
CH4 + 2 O2 -> 2 H2O + CO2
Because they are both broke apart over time
Answer:
All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. In some chemical reactions, called exothermic reactions, more energy is released when new bonds form in the products than is needed to break bonds in the reactants. The opposite is true of endothermic reactions. In an endothermic reaction, it takes more energy to break bonds in the reactants than is released when new bonds form in the products. This is all an ethemic reaction.
