Help me. ASAP!!!!! 23 POINTS!!!!!!!

Alona [7]

a) Group 2 elements have 2 electrons on their outer shell, so they form a 2+ charge.

b) they lose 2 electrons as they are transferred to the non metal.

c)They obtain this charge as when they are made into an ionic compound the 2 electrons on the outer shell are transferred to the non metal, meaning there are 2 more protons that electrons, giving it a positive charge.

hope this helps! :)

A 8.00g of a certain Compound X, known to be made of carbon, hydrogen and perhaps oxygen, and to have a molecular molar mass of

Ne4ueva [31]

Answer:

C3H6.

Explanation:

Data obtained from the question:

Mass of the compound = 8g

Mass of CO2 = 24.01g

Mass of H2O = 13.10g

Next, we shall determine the mass of C, H and O present in the compound. This is illustrated below:

Molar Mass of CO2 = 12 + (2x16) = 44g/mol

Molar Mass of H2O = (2x1) + 16 = 18g/mol

Mass of C in compound = Mass of C/Molar Mass of CO2 x 24.01

=> 12/44 x 24.01 = 6.5g

Mass of H in the compound = Mass of H/Molar Mass of H2O x 13.1

=> 2x1/18 x 13.1 = 1.5g

Mass of O in the compound = Mass of compound – (mass of C + Mass of H)

=> 8 – (6.5 + 1.5) = 0

Next, we shall determine the empirical formula of the compound. This is illustrated below:

C = 6.5g

H = 1.

Divide by their molar mass

C = 6.5/12 = 0.54

H = 1.4/1 = 1.

Divide by the smallest

C = 0.54/0.54 = 1

H = 1/0.54 = 2

Therefore, the empirical formula is CH2

Finally, we shall determine the molecular formula as follow:

The molecular formula of a compound is a multiple of the empirical formula.

Molecular formula = [CH2]n

[CH2]n = 44

[12 + (2x1)]n = 44

14n = 44

Divide both side by 14

n = 44/14

n = 3

Molecular formula = [CH2]n = [CH2]3 = C3H6

Therefore, the molecular formula of the compound is C3H6

An oil company located a area of oil sands and began an analysis of two possible extraction methods. The oil is heavy oil, makin

Rus_ich [418]

The cost for CHOPS is in the sand and the extraction of the oil from sand.
The cost for SAGD is the generation of steam.
The benefit for CHOPS is the low cost.
The benefit for SAGD is high extraction efficiency.
The other factors that could affect the decision are fuel cost and the required purity of the oil.

If a barometer were built using ethanol () instead of mercury (), would the column of ethanol be higher than, lower than, or the

Semenov [28]

Answer:

The column of ethanol will be higher than the column of mercury.

Explanation:

The pressure (P) of a column of liquid can be calculated using the following expression.

P = ρ . g . h

where,

ρ: density of the liquid

g: gravity

h: height of the column

h = P / ρ . g

We can see that the height of the column is inversely proportional to the density of the liquid. The density of ethanol (0.789 g/mL) is lower than the density of mercury (13.6 g/mL). Then, under the same conditions, the column of ethanol will be higher than the column of mercury.
