Answer: The molarity of
anions in the chemist's solution is 0.0084 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,
n = moles of solute
= volume of solution in ml
moles of
= 
Now put all the given values in the formula of molality, we get

As 1 mole of
gives = 3 moles of 
0.0028 moles of
gives =
of 
Thus the molarity of
anions in the chemist's solution is 0.0084 M

Answer:
Positively Charged
Explanation:
The is a group XVI and period 4 element of the periodic table with similar physical and chemical to that of tellurium and sulfur. Selenium exist in different allotropic forms, which have different solubility including selenate, selenite and selenium in elemental form
The Se ion in selenate has a positive charge of +6, while the selenate ion has a charge of -2
The Se ion in selenite has a charge of +4, while the selenite ion has a negative charge of -2.
The charge of Se in elemental selenium is 0.
Carbon dioxide, when excess in number, becomes a greenhouse gas According to sources, the most probable answer to this query is that carbon dioxide is one of the greenhouse gases that traps heat affecting climate. This increase in heat turns the temperature higher. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
