Water is made of polar molecules, and oil is made of nonpolar molecules. Based on your observations, which molecules attract eac

victus00 [196]

Based on observation of polar and non-polar molecules, polar molecules would attract each other more strongly.

<h3>What are polar and non-polar molecules?</h3>

Polar molecules are those molecules that can ionize or dissociate into their respective positive and negative ions when in an aqueous solution.

Nonpolar molecules, on the other hand, are not ionic i.e. not dissociating into ions when dissolved in water.

Polar molecules like water (H2O) contains an uneven distribution of cations (+) and anions (-), hence, would be more attracted to one another than nonpolar molecules that have an even distribution of ions.

Peroxyacylnitrate (PAN) is one of the components

coldgirl [10]

C – 19,9%, H – 2,2%, N – 11,6%, O – x%

$M=120\frac{g}{mol}$

1 percentage

The entire molecule is 100% and all the components of the compound add up to 100%.

100% - 19,9% - 2,5% - 11,6% = 66,1%

The compound contains 66,1% oxygen.

2 molar masses

$M_{C}=12,01\frac{g}{mol}$

$M_{H}=1,008\frac{g}{mol}$

$M_{O}=15,999\frac{g}{mol}$

$M_{N}=14,007\frac{g}{mol}$

3 masses

The compound has a molar mass of 120g/mol. So one molecule weighs 120 g. To find out how much the percentage of a component weighs, you have to calculate it using the molar mass.

carbon

19,8% of 120g

$m=120g*0,198\\m=23,76g$

One molecule contains 23,76g of carbon.

hydrogen

2,5% of 120g

$m=120g*0,025\\m=3g$

One molecule contains 3g of hydrogen.

oxygen

66,1% of 120g

$m=120g*0,661\\m=79,32g$

One molecule contains 79,32g of oxygen.

nitrogen

11,6% of 120g

$m=120g*0,0,116\\m=13,92g$

One molecule contains 13,92g of nitrogen.

4 amount of substance

carbon

$n=\frac{23,76g}{12,01\frac{g}{mol} }\\n=1,98mol$

The compound contains about 2 moles of carbon.

hydrogen

$n=\frac{3g}{1\frac{g}{mol} }\\n=3mol$

The compound contains about 3 moles of hydrogen.

oxygen

$n=\frac{79,32g}{15,999\frac{g}{mol} }\\n=4,96mol$

The compound contains about 5 moles of oxygen.

nitrogen

$n=\frac{13,92g}{14,007\frac{g}{mol} }\\n=0,99mol$

The compound contains about 1 moles of nitrogen.

5. molecular formula

The formula results from the ratio of the amounts of substance.

$n_{C} :n_{H} :n_{O} :n_{N} =2:3:5:1\\C_{2}H_{3}NO_{5}$

Correctly identify the generic formula for a double replacement reaction.

devlian [24]

Answer:

AB + CD → AC +BD

Explanation:

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

Example:

The following reaction is double replacement reaction.

CaCO₃ + 2HCl → CaCl₂ + H₂CO₃

While,

A + B → AB

Synthesis reaction:

It is synthesis reaction. The reaction in which two or more simple substance react to give one or more complex product.

AB → A + B

Decomposition:

It is the decomposition reaction. The reaction in which one reactant is break down into two or more product.

AB + C → AC + B

Single replacement:

It is the reaction in which one elements replace the other element in compound.

Convert 88.2°C into °F

prisoha [69]

The formula for converting Celsius to Fahrenheit is:
Let Celsius be C

(C * 1.8) + 32 = the value in Fahrenheit.

(88.2*1.8) + 32 = 190.76 degrees Fahrenheit.

Hope this helps!
