Answer:

The answer is: carbon

Explanation:

Organic molecules contain the chemical element carbon (C) in its structure. In this type of molecules, carbon is usually bonded to hydrogen (H), oxygen (O) and, with less frecuency, nitrogen (N). Therefore, in these molecules, carbon forms simple, double and triple bonds with itself. Examples of organic molecules that are very important in biology are carbohydrates, lipids, proteins and nucleic acids.

When road contractors are laying cement,they first place a series of steel rods in a specific patterns. the they pour the cement

Anna11 [10]

The steel rods will enable the concrete to form without any bumps and it will add shape to the cement and strength, so no odd massive lumps are formed.

That is what I think anyways :)

above shows a balloon full of gas which has a volume of 120.0ml at 300.0k assuming pressure remains constant , what is the voume

trasher [3.6K]

128 ml is the voume of the balloon if the temperature of the gas increases to 320.0k.

Explanation:

given that:

T1 (initial temperature) = 300K

V1 ( initial volume) = 120ml

T2 (final temperature) = 320 K

V2 (final volume) = ?

Pressure remained constant throughout the process.

From the equation

$\frac{P1V1}{T1}$ = $\frac{P2V2}{T2}$

Since pressure is constant the equation will be:

$\frac{V1}{T1}$ = $\frac{V2}{T2}$

V2 = $\frac{V1 X T2}{T1}$

Putting the values in the above formula:

V2 = $\frac{120 X 320}{300}$

= 128 ml

128 ml is the volume of the gas if temperature increases from 3OO K to 320k

Which of the following conversion factors would be used to calculate the number of moles of Cl2 produced if 11 moles of HCl were

MissTica

Answer: The moles of chlorine gas produced is 5.5 moles

Explanation:

We are given:

Moles of HCl = 11 moles

For the given chemical reaction:

$4HCl+O2\rightarrow 2Cl_2+2H_2O$

By Stoichiometry of the reaction:

4 moles of HCl produces 2 moles of chlorine gas

So, 11 moles of HCl will be produced from $\frac{2}{4}\times 11=5.5mol$ of chlorine gas

Hence, the moles of chlorine gas produced is 5.5 moles

Why are plant oils important in our diet?

Lesechka [4]

Plant oil or also called as vegetable oils are considered as important part of our diet because it is the source of energy in our diet. Foods that are cooked using vegetable oils produce more energy than to those foods that are cooked using other oil. Vegetable oils also contains saturated and unsaturated fats and oils.
Vegetable oil or plant oil are healthier compare to the other oil. It also lessen the unwanted and unhealthy fats of an oil and gives only proper health diet to our body.
