Answer:
Mg is oxidized and Pb is the oxidizing agent
Explanation:
Answer:
- The molar mass of the solute, in order to convert from moles of solute to grams of solute.
- The density of solution, to convert from volume of solution to mass of solution.
Explanation:
Hello,
In this case, since molarity is mathematically defined as the moles of solute divided by the volume of solution and the weight/weight percent as the mass of solute divided by the mass of solution, we need:
- The molar mass of the solute, in order to convert from moles of solute to grams of solute.
- The density of solution, to convert from volume of solution to mass of solution.
For instance, if a 1-M solution of HCl has a density of 1.125 g/mL, we can compute the w/w% as follows:

Whereas the first factor corresponds to the molar mass of HCl, the second one the conversion from L to mL of solution and the third one the density to express in terms of grams of solution.

Selena can change from burning fossil fuel in her home to using solar energy.
<h3>What causes climate changes?</h3>
Climate change is caused by the release of the greenhouse gases which is gotten through the use and burning of fossil fuels such as coal.
The use of solar panels and solar energy by Selena in her house can help adjust the climate changes by decreasing the amount of greenhouse gases released into the atmosphere.
