Answer and explanation :

DIFFERENCE BETWEEN HOMOGENEOUS AND HETEROGENEOUS MIXTURE :

In homogeneous mixture the component which are present in the mixture all are in the same proportion whereas in heterogeneous mixture the component which are present in the mixture don't have the same proportion
We can not pick out the component of homogeneous mixture but in heterogeneous mixture we can pick out the components from the mixture
Example of homogeneous mixture is water, oil ,water sugar solution, milk blood etc. And example of heterogeneous mixture is solution of sand and water ,concrete etc.

A 31 g sample of a compound that contained only

vfiekz [6]

The question is incomplete, the complete question is;

A 31 g sample of a compound that contains only the elements C,H and N is completely burned in O2 to produce 44.0 g of CO2, 45.0 g of H2O, and 92.0 g of NO2. Determine the empirical formula of the compound.

Answer:

CH5N2

Explanation:.

Mass of C = 44.0g/44.0 g/mol = 1 mol * 1 = 1 mole of C

Mass of H = 45.0 g/18 g/mol = 2.5 moles * 2 = 5 moles of H

Mass of N = 92.0 g/46 g/mol = 2 moles * 1 = 2 moles of N

Dividing through by the lowest mole ratio;

1/1, 5/1, 2/1

1 : 5 : 2

Hence the empirical formula is;

CH5N2

Answer:

$NH^{+} _{4}$ ammonium ion.

Explanation:

Check the box next to each molecule on the right that has the shape of the model molecule on the left: model molecules (check all that apply X 5 ? | O CH20 CNH, You can drag the slider to rotate the model molecule. + 1 O Brf 4 CH2Cl2 Note for advanced students: the length of bonds and size of atoms in the model is not necessarily realistic. The model is only meant to show you the general geometry and 3D shape of the molecule.

when you look at the diagram from the source page

one can conclude that the diagram is tetrahedral and the angle between the molecules is 109.5 deg

There is one central atom bonded to four atoms in a tetrahedral molecule .it has no lone electron pairs.m

NH4+ is the answer

Other molecules that are tetrahedral in shape are methane ion and phosphate ion.
