2H2 + O2 \rightarrow 2H2O

PV = nRT

since assuming that the reactants and product are all at the same temperature and pressure, the molar ratio of reactants = volume ratio of reactants.

The chemical reaction between Hydrogen and oxygen is as follows:

2H2 + O2 ---> 2H2O

2.......1........2 (volume ratio = molar ratio at same condition of temperature and pressure)

Given that  

oxygen volume = 22.5L

Volume of H2O =22.5 L volume oxygen  * 2 volume H2O /  1.0 L volume oxygen

= 45 L water

Answer:

45 L

Explanation:

Assuming normal temperature and pressure (NTP) and ideal gas behaviour, 22.5 L are equivalent to:

PV = nRT

n = PV/RT

n = (1*22.5)/(0.082*273.15)

n = 1 mol

Oxygen and hydrogen react to form water as  follows:

2 H2 (g) + O2 (g) -> 2 H2O (g)

From the balanced equation, we know that 1 mol of Oxygen produces 2 moles of water. The volume occupied by these 2 moles is:

PV = nRT

V = nRT/P

V =  2*0.082*273.15/1

V = 45 L

Know we can see the assumption of NTP conditions was unnecessary, the ratio between moles of oxygen consumed and moles of water produced is 1:2, so the ratio between volumes.

Intensive properties are useful for identifying a substance simply because these properties do not depend on the amount of sample, nor do they change according to conditions.

The correct answer choice which is a physical property of matter is boiling point.

Polymers are long chains of <u>molecules</u>

The method which I would use to separate two liquids with different boiling points is <u>distillation</u>

The particles are located in the nucleus of an atom are protons and neutrons

The type of molecular model which is used to represent very large molecules like proteins is ribbon diagram

The methods which is used to separate a mixture according to the size of the particles are filtration and chromatography

<h3>What is a mixture?</h3>

A mixture is a substance which contains two or more constituents which can easily be separated by physical means

So therefore, the methods which is used to separate a mixture according to the size of the particles are filtration and chromatography

The combustion of one mole of liquid ethanol, CH3CH2OH, produces 1367 kJ of heat. Calculate how much heat is produced when 235.0
deff fn [24]

Answer:- 6984 kJ of heat is produced.

Solution:- From given information, 1367 kJ of heat is produced by the combustion of 1 mole of ethanol. We are asked to calculate the heat produced by the combustion of 235.0 g of ethanol.

Let's convert given grams to moles and multiply by the heat produced by one mole of ethanol to get the total heat produced. Molar mass of ethanol is 46 grams per mole. The set will be:

235.0g(\frac{1mole}{46g})(\frac{1367 kJ}{1mole})

= 6984 kJ

So, 6984 kJ of heat is produced by the combustion of 235.0 g of liquid ethanol.

Calculate the Molarity of 89.94 g NaCl is dissolved in 1249 mL of solution.<br><br> e
Dmitriy789 [7]

Answer:

Molarity = 1.23 M

Explanation:

Given data:

Molarity of NaCl = ?

Mass of NaCl = 89.94 g

Volume of solution = 1249 mL ( 1249/1000 = 1.249 L)

Solution:

First of all we will calculate the number of moles of NaCl.

Number of moles = mass/molar mass

Number of moles = 89.84 g/ 58.5 g/mol

Number of moles = 1.54 mol

Molarity:

Molarity = Number of moles of solute / volume of solution in L

Molarity = 1.54 mol / 1.249 L

Molarity = 1.23 M
