What is the molecular formula for C5H7 if its molar mass is 536 g/mol?
Answer:
(C5H7)8
Explanation:
It's empirical formula is given as; C5H7
Molar mass of carbon(C) = 12 g/mol
Molar mass of hydrogen(H) = 1 g/mol
We are told that it's molar mass is 536 g/mol.
To find the molecular formula;
Molecular formula = n × empirical formula
Thus;
n = 536/((12 × 5) + (1 × 7))
n = 8
Thus;
Molecular formula = (C5H7)8

A. ---, 2, 2, ---
B. 2, ---, ---, 2
C. 2, ---, 2, ---
Answer:
2 NaF + Br2 --> 2NaBr + F2
Explanation:
Well first I notice that there are two flourines on the products side so we need to put a 2 of NaF. Now there are 2 sodiums on the products side so we have to put another two in front of NaBr.
2 NaF + Br2 --> 2NaBr + F2
give two areas where the compressible nature of gas is applied
Answer:
1. Gases can be easily liquefied into very small volumes and stored in liquid form Eg in LPGA cylinders and used in homes.
2. Balloons can be easily filled with air.
The fact that a gas is easily compressible is applied in the colling devices such as air conditioners as well as in the pumping of tyres with air.
Are gases compressible?Gases are easily compressible because they do not have a definite volume. This is positively applied in many areas of life.

For the reaction 2NH3(g) + O2(g) -> 2NO(g) + 3H2O(g). The reaction is run using 824 g NH3 and excess oxygen. How many moles of NO are formed? How many moles of H2O are formed?
Answer:
Explanation:
Step One
Find the molar Mass of NH3
N = 14
3H = 3
Mass = 17
Step Two
Find the number of moles of NH3
mols = given mass / Molar Mass
given mass = 824 grams
molar mass = 17
mols = 824/17
mols = 48.47
Step Three
Find the moles of NO
Here you have to look at the balanced equation
Every 2 mols of HN3 produces 2 mols of NO
So the number of mols of NH3 = 48.47
The number of mols of NO = 48.47
Step Four
Find the mols of H2O
2 mols of NH3 produces 3 moles of H20
48.47 mols H20 produces x moles of H20
3/x = 2/48.47 Cross Multiply
2x = 3*48.47
2x = 145.41 Divide by 2
x = 145.41/2
x = 72.71 mols of water.
A cup of coffee is made in the morning by pouring water ov er ground up coffee beans in a piece of paper and by collecting the brown liquid that comes through. Which techniques used
Answer: Filtration technique
Explanation:
The technique used here is called filtration.
Filtration,is a physical separation process that separates a mixture of an insoluble solid from a liquid ( acting as the solvent) by the use of a filter barrier that allows only the fluid to pass through.
In the case from the question,
As water is poured over the ground coffee, it forms a mixture of which the insoluble solid is the coffee grounds, the water is the liquid and the filter barrier is the piece of paper which allows only the brown liquid coffee to pass through as the filtrate.

A gas at a pressure of 360 torrs and a volume of 750 ml. If the pressure becomes 1.5 atm what is the new volume?
Answer:
V₂ = 236.84 mL
Explanation:
The relation between pressure and volume is inverse.
We can write it as follows :
[tex]P_1V_1=P_2V_2[/tex]
We have,
P₁ = 360 torrs, V₁ = 750 mL, P₂ = 1.5 atm = 1140 torr.
So,
[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{360\times 750}{1140}\\\\V_2=236.84\ mL[/tex]
So, the new volume of the gas is 236.84 mL.

When kci dissolved in ethanol what is the intermolecular attraction between k+ ions and ethanol molecules
Answer:
ion-dipole interaction
Explanation:
Ethanol is a polar molecule due to the presence of the polar O-H group in the molecule. This means that the molecule has a dipole moment.
The positive end of the dipole lies on hydrogen while the negative end of the dipole lies on oxygen.
When KCl is dissolved in ethanol, K^+ ions can interact with the negative end of the dipole in ethanol by ion-dipole interaction.
