A bubble of helium gas has a volume of 0.65 L near the bottom of a large
Flura [38]

Answer:

0.73L

Explanation:

The following data were obtained from the question :

V1 = 0.65 L

P1 = 3.4 atm

T1 = 19°C = 19 + 273 = 292K

V2 =?

P2 = 3.2 atm

T2 = 36°C = 36 + 273 = 309K

The bubble's volume near the top can be obtain as follows:

P1V1 /T1 = P2V2 /T2

3.4 x 0.65/292 = 3.2 x V2 /309

Cross multiply to express in linear form as shown below:

292 x 3.2 x V2 = 3.4 x 0.65 x 309

Divide both side by 292 x 3.2

V2 = (3.4 x 0.65 x 309) /(292 x 3.2)

V2 = 0.73L

Therefore, the bubble's volume near the top is 0.73L

Write the empirical formula of a list for binary ionic compounds that could be formed from the following ions
klasskru [66]

Answer:

CaBr₂, CaO, FeBr₂, FeO

Explanation:

Per binary compound, there must be 1 cation (Ca²⁺, Fe²⁺) and 1 anion (Br⁻, O²⁻). The compound should have a charge of 0 (neutral). For this to occur, there sometimes needs to be more than one cation/anion present in the compound. Below I have included the math that displays why there are more ions necessary in some compounds.

CaBr₂

-----> Ca = +2 and Br = -1

-----> +2 + (-1) + (-1) = 0

CaO

-----> Ca = +2 and O = -2

-----> +2 + (-2) = 0

FeBr₂

-----> Fe = +2 and Br = -1

-----> +2 + (-1) + (-1) = 0

FeO

-----> Fe = +2 and O = -2

-----> +2 + (-2) = 0
