it would be 0.75 atm
Answer:
Unit rate at which Martin paints in walls per gallon is .
Explanation:
Rate is defined as ratio between two quantities with different units.
Gallons of paint used by Martin = gallons
Portion of wall Martin wishes to pint = wall
Rate at which Martin paints the wall:
Unit rate at which Martin paints in walls per gallon is .
Answer:
B. Two chlorine atoms
Explanation:
This electronic configuration shows that the given atom is magnesium.
Electronic configuration of magnesium:
Mg¹² = 1s² 2s² 2p⁶ 3s²
There are two valance electrons of magnesium that's why it would react with two atoms of chlorine. Chlorine is present in seventeen group. It has seven valance electrons. It required just one electron to get complete octet. While magnesium needed to lose two electrons to get complete octet. That's why two chlorine atoms bonded with one magnesium atom. Thus both would get complete octet.
Mg + Cl₂ → MgCl₂
a. distillation
b. chromatography
c. filtration
d. crystallization
Answer:
c.filtration is the answer
Explanation:
Number of moles consisting in a liter of solution is known as molarity.
Mathematically, Molarity = \frac{\text{no. of moles}}{\text{Volume in one liter}}[/tex]
It is given that volume is 10 liter and there is 5.0 moles of solute. Hence, we will calculate the molarity as follows.
Molarity =
=
= 0.5 mol/L
Thus, we can conclude that molarity of the given solution is 0.5 mol/L.
