The following experiment was performed: A white solid was added to a test tube containing water. The solid completely dissolved
Morgarella [4.7K]

Answer:

Potassium iodide

Explanation:

The white solid introduced into the solution is potassium bromide. This is an ionic solid thus it quickly dissolves in water to yield a colorless solution.

When chlorine is added to this solution, the iodine is displaced since chlorine is above iodine in the electrochemical series.

When mixed with hexane, the color of the solution changes to purple.

Element R and Element Q have the same number of valence electrons.These elements both haves similar chemical behavior, but Eleme
vovangra [49]

Answer:

This question is incomplete

Explanation:

This question is incomplete, however, element R and element Q having the same number of valence electrons means they belong to the same group in the periodic table which is the reason for there similar chemical behavior (as elements in the same group tend to have the same chemical properties).

Element R having fewer energy level (or electron shell) than element Q shows element R has fewer number of electrons than element Q and can be found earlier in the periodic table (or group in particular) when compared to element  Q

Balance this chemical formula<br> Fe + Cl2 = FeCl3
san4es73 [151]
First you find out how much each element has

Fe=1 * 2                    Fe=1
Cl=2  *3                   Cl=3 *2

now we multiply each so we can balance each side.

So now we get our balanced equation
2 Fe + 3 Cl2 = 2 FeCl<span>3</span>

A latex balloon at sea level and room temperature (25°C) has a volume of 2.42 L. When the balloon is released by the child holdi
yarga [219]

Answer:

The answer to your question is: V2 = 1.94 l

Explanation:

Data

V1 = 2.42 l

T1 = 25°C

P1 = 1 atm

V2 = ?

T2 = 25 -11 = 14°C

P2 = 1(0.7) = 0.7 atm

Formula

P1V1/T1 = P2V2/T2

Clear V2 from the equation

V2 = P1V1T2/ P2T1

V2 = (1)((2.42)(14) / (0.7)(25)

V2 = 33.88 / 17.5

V2 = 1.94 l
