Answer:

What is the difference between pools and fluxes?

Image result for Is industry pool or flux

Fluxes describe the movement of energy and matter between different pools. When you pour a glass of juice for yourself, the juice bottle and the glass are both “pools” for the apple juice. The act of pouring it from the bottle to the glass is the flux

Mg(OH)2 + 2 HBr à MgBr2 + 2 H2O

AnnyKZ [126]

Explanation:

The balanced equation of the reaction is given as;

Mg(OH)2 (s) + 2 HBr (aq) → MgBr2 (aq) + 2 H2O (l)

1. How many grams of MgBr2 will be produced from 18.3 grams of HBr?

From the reaction;

2 mol of HBr produces 1 mol of MgBr2

Converting to masses using;

Mass = Number of moles * Molar mass

Molar mass of HBr = 80.91 g/mol

Molar mass of MgBr2 = 184.113 g/mol

This means;

(2 * 80.91 = 161.82g) of HBr produces (1 * 184.113 = 184.113g) MgBr2

18.3g would produce x

161.82 = 184.113

18.3 = x

x = (184.113 * 18.3 ) / 161.82 = 20.8 g

2. How many moles of H2O will be produced from 18.3 grams of HBr?

Converting the mass to mol;

Number of moles = Mass / Molar mass = 18.3 / 80.91 = 0.226 mol

From the reaction;

2 mol of HBr produces 2 mol of H2O

0.226 mol would produce x

2 =2

0.226 = x

x = 0.226 * 2 / 2 = 0.226 mol

3. How many grams of Mg(OH)2 are needed to completely react with 18.3 grams of HBr?

From the reaction;

2 mol of HBr reacts with 1 mol of Mg(OH)2

18.3g of HBr = 0.226 mol

2 = 1

0.226 = x

x = 0.226 * 1 /2

x = 0.113 mol

which of the following is a balanced chemical equation for the reaction of magnesium with nitrogen gas to form magnesium nitride

ioda

So the unbalanced equation would be Mg + N^2 --> Mg^3N^2

Which means the balanced equation would be 3Mg + N^2 --> Mg^3N^2

This is balance the equation out since you now has 3 magnesium and 2 nitrogen on the left side, and 3 magnesium on 2 nitrogen on the right. Double check my work though, it's been awhile.

A scientist has isolated a fatty acid that has 26 carbons. most of the carbon atoms in the fatty acid chain are connected by sin

Shtirlitz [24]

Answer:
Based on giveninformation, the compound is a Poly Unsaturated fatty acid.

Explanation:
Fatty acids are carboxylic acids with -COOH functional group and a chain of hydrocarbons.

Fatty Acids are classified as,

i) Saturated Fatty Acids:
Those Fatty Acids in which there is no double bond between the carbon chain are called as saturated fatty acids.

Examples:
Lauric Acid CH₃(CH₂)₁₀COOH

Myristic Acid CH₃(CH₂)₁₂COOH

Palmitic Acid CH₃(CH₂)₁₄COOH

ii) Unsaturated Fatty Acids:
Those Fatty Acids in which contain a single double bond (mono-unsaturated) or more than one double bond (poly-unsaturated) d between the carbon atoms in a chain are called as unsaturated fatty acids.

Examples:
Linoleic acid

Vaccenic acid

Palmitoleic acid

The saturated fatty acid containing 26 carbon atoms is called as Cerotic acid. While cerotic acid containing a double bond at position 3 and 9 has a IUPAC name Hexacosa-3,9-dienoic acid with following structure.

andreyandreev [35.5K]

Cylinder A - Adding 25 grams raised the water level by roughly 3.2 mL

Cylinder B - Adding 25 grams raised the water level by roughly 2.8 mL

Cylinder C - Adding 25 grams raised the water level by roughly 3.5 mL

Calculate grams/mL (density)

A. 25 g/3.2 mL = 7.8125 g/mL = Iron
B. 25 g/2.8 mL = 8.9286 g/mL = Nickel
C. 25 g/3.5 mL = 7.1429 g/mL = Zinc

Hope I helped!
