Answer:
They usually lose electrons to form ions with 2 positive charges
Explanation:
To determine the total charge of the protons in the gas, we need to know the number of protons that are present. We use Avogadro's number to know such value. We do as follows:
2.2 mol ( 6.022x10^23 protons / 1 mol ) = 1.325x10^24 protons
Total charge = 1.6021766208×10^−19 C (1.325x10^24) = 212262.77 C
Common insoluble (sparingly soluble) salts are carbonates, hydroxides<span>, sulfates, and sulfides.</span>
In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.
