Answer:

11.25moles of CO2

Explanation:

First, let us generate a balanced equation for the reaction of propane to produce CO2. This reaction called Combustion. It is a reaction in which propane burns in air (O2) to produce CO2 and H20. The equation is given below:

C3H8 + 5O2 —> 3CO2 + 4H2O

From the equation,

1mole of C3H8 produced 3moles of CO2.

Therefore, 3.750 moles of C3H8 will produce = 3.750 x 3 = 11.25moles of CO2

Determine if the individual bonds in each compound are polar or nonpolar.

almond37 [142]

Answer:

See explanation

Explanation:

For SCl2

S = 2.8, Cl = 3.16 difference = 0.4 polar

H2S

H = 2.2 S= 2.8 difference = 0.6 polar

CF4

C = 2.55, F= 3.98 difference = 1.43

This compound is nonpolar irrespective of the difference in electronegativity because the molecule is symmetrical

PCl5

P= 2.19, Cl= 3.16 difference = 0.97

This compound is nonpolar irrespective of the difference in electronegativity because the molecule is symmetrical

CH4

C = 2.55 H = 2.2 difference = 0.35 the molecule is nonpolar

CaBr2

Ca= 1 Br= 2.96 difference = 1.96

The compound is not just polar but ionic in nature due to large electronegativity difference between the bonding atoms

SF2

S = 2.8 F= 3.98 difference = 1.18

The molecule is polar

CO2

C= 2.55 O= 3.44 difference = 0.89

This compound is nonpolar irrespective of the difference in electronegativity because the molecule is symmetrical

NH3

N= 3.04 H = 2.2 difference =0.84

The molecule is polar

NaS

Na= 0.93 S = 2.8 difference = 1.87

The compound is not just polar but ionic in nature due to large electronegativity difference between the bonding

1) what causes the magnetic fields on the sun?

mr Goodwill [35]

1) flows of hot plasma in the convection zone
2) dark spots that appear sometimes because of concentrations of magnetic field flux
3) "a brief eruption of intense high-energy radiation from the sun's surface"
4) gas extended out from the corona but is attached to the sun and can reach great distances
5) large area in cocrona which is less dense and has cooler temperature they occur when "the Sun's magnetic field is open to interplanetary space"

The principle applied to the design of an airplane wing was developed by

Bond [772]

Answer:

<h2>Bernoulli’s Principle</h2>

This states principle helps explain that an aircraft can achieve lift due to the shape of its wings.

They wings are shaped that way so that that air flows faster over the top of the wing and slower underneath the wing .

In simple terms ;

Fast moving air equals low air pressure while slow moving air equals high air pressure

Dolomite is a carbonate of magnesium and calcium. Analysis shows that 7.81 g of dolomite contains 1.70 grams of Ca. Fluorite is

andrew11 [14]

Answer:

The richer source of calcium is fluorite.

Explanation:

Percentage of element in compound :

$=\frac{\text{mass of element}}{\text{Mass of compound}}\times 100$

1. Dolomite is a carbonate of magnesium and calcium:

Given mass of dolomite = 7.81 g

Mass of calcium present in given mass of dolomite = 1.70 g

Percentage of calcium in Dolomite:

$=\frac{1.70 g}{7.81 g}\times 100=21.77\%$

2. Fluorite is a mineral of calcium and fluorine:

Given mass of fluorite = 2.76 g

Mass of fluorine present in given mass of fluorite = 1.34 g

Percentage of fluorine in fluorite :

$=\frac{1.34 g}{2.76 g}\times 100=48.55\%$

Percentage of calcium in fluorite = 100% - 48.55 % = 51.45%

Percentage of calcium in fluorite > Percentage of calcium in Dolomite

51.455 > 21.77%

So, the richer source of calcium is fluorite.
