Answer: polar solvent
Explanation:
Polarity can be said to mean, charge separation. Thus, polar solvents are solvents that have charge separation and the ability to solvate i.e dissolve ions.
A polar solvent molecule has slight electrical charge as a result of its shape. A typical and most common example is water, with an oxygen and two hydrogen atoms. The two hydrogen atoms are at an angle to the single oxygen atom. Water is the classic polar solvent. The oxygen atom tends to polarize electron density to itself.
Answer: The metalloids are a unique group of elements that share properties of both metals and nonmetals.
Explanation: They're also called the semimetals because of the shared properties of these elements along the dividing line between metals and nonmetals.
Answer:
Left or up, either one of those
Explanation:
Answer: 118.5 grams
Explanation:
Molarity 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 = 500 ml

moles = 0.75
moles of solute =
0.75 =
mass of
= 118.5 grams
Thus mass of
needed to prepare 500 mL of this solution iis 118.5 grams
Answer:
Classification will be Potassium, Bromine, and Argon
Explanation:
- Potassium is more likely to lose electrons and form positive ion
- Bromine actually gain electrons and forms negative ion
- Argon does not lose or gain electrons
