How much water must be evaporated from 240 gallons of a 3 salt solution?

Chemistry
1 answer:
Greeley [361]3 years ago
4 0
THERE IS A TOTAL OF 240*.03=7.2 GALLONS OF SALT IN THE 240 GALLONS.
TO GET A 5% SOLUTION YOU MUST DRAIN ENOUGH TO GET LEAVE THE FOLLOWING
.05X=7.2
X=7.2/.05
X=144 GALLONS OF WASTER WITH 7.2 GALLONS OF SALT IS A 5% SOLUTION.
THEREFORE YOU MUST EVAPORATE
240-144=96 GALLONS OF WATER.

Which is not true about enantiomers?
Yanka [14]

Answer:

C

Explanation:

Enantiomers are molecules that are mirror images of one another. This means they have the same connectivity of the same atoms in the molecules but have an opposite 3-dimensional orientation – like the two palms of the hand.  This means they polarised light in opposite directions but with equal effect.

A comparison often made between solids and
Mandarinka [93]

The density of a plasma can be described as : ( A ) Low density

<h3><u>Density </u></h3>

Density is the mass per unit volume of a substance, it is used for comparison between substances because the mass and volume which are scalar quantities of substances are applied.

The density of plasmas are low when compared to solids because the volume occupied by a plasma of the same mass as a solid, is greater when compared to the volume occupied by a solid.

Hence we can conclude that The density of a plasma can be described as Low density.

What is produced during the replacement reaction of ba(no3)2 and na2so4? 2bana 2no3so4 2nano3 baso4 nano3 baso4 bana2 (no3)2so4
Cloud [144]

2NaNO3(aq) + BaSO4 = Ba(NO3)2(aq) + Na2SO4(aq) (s)

Procedures involved:

The cations or anions may transfer positions in this twofold replacement/displacement reaction, which results in AB + CD AD + CB. In such a reaction, water, an insoluble gas, or an insoluble solid must be one of the byproducts (precipitate). The reaction in question has the following molecular equation:

2NaNO3(aq) + BaSO4 = Ba(NO3)2(aq) + Na2SO4(aq) (s)

Double displacement:

When two atoms or groups of atoms swap positions, a double displacement reaction occurs, creating new compounds. Typically, aqueous solutions are where it happens.

Na2SO4 + BaCl2 BaSO4 + 2NaCl is an example of a double displacement reaction.
