A pure chemical substance

Explanation:

A pure substance is any substance made up of only one kind of matter and has definite properties.

Matter is anything that has weight and occupies space

On a broad basis, matter can be categorized as pure or distinct substances and impure substances or mixtures.

Pure substances have the following properties;

  • All parts of a pure substance remains the same throughout i.e homogeneous.
  • Their composition is definite
  • They cannot easily be broken or separated down into simpler substances by physical means.

They have a unique set of chemical properties.

Pure substances are elements and compounds.

When 1.5 grams of magnesium burns, how many grams of magnesium oxide will be formed?
SashulF [63]
The balanced chemical reaction for this would be written as:

2Mg + O2 = 2MgO

We use this reaction and the amount of the reactant given to calculate for the amount of magnesium oxide that is produced. We do as follows:

1.5 g Mg (1 mol / 24.31 g) ( 2 mol MgO / 2 mol Mg ) (40.30 g /1 mol ) = 2.49 g MgO produced

Jason ran 5/7 of the distance around the school track sara ran 4/5 of Jason distance what fraction of the total distance around
FrozenT [24]
Let x represent the total distance around the track
Jason's distance: (5/7)x
Sara ran (4/5) of Jason's distance,
so she ran (4/5)*(5/7)x = (4/7)x
Sara ran 4/7 of the total distance

The dissolution of 0.200 l of sulfur dioxide at 19 °c and 745 mmhg in water yields 500.0 ml of aqueous sulfurous acid. The solut
aivan3 [116]

Answer:

Molarity=1.22\ M

Explanation:

Given:  

Pressure = 745 mm Hg

Also, P (mm Hg) = P (atm) / 760

Pressure = 745 / 760 = 0.9803 atm

Temperature = 19 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T₁ = (19 + 273.15) K = 292.15 K  

Volume = 0.200 L

Using ideal gas equation as:

PV=nRT

where,  

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value = 0.0821 L.atm/K.mol

Applying the equation as:

0.9803 atm × 0.200 L = n × 0.0821 L.atm/K.mol × 292.15 K  

⇒n = 0.008174 moles

From the reaction shown below:-

H_2SO_3+2NaOH\rightarrow Na_2SO_3+2H_2O

1 mole of H_2SO_4 react with 2 moles of NaOH

0.008174 mole of H_2SO_4 react with 2*0.008174 moles of NaOH

Moles of NaOH = 0.016348 moles

Volume = 13.4 mL = 0.0134 L ( 1 mL = 0.001 L)

So,

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Molarity=\frac{0.016348}{0.0134}\ M

Molarity=1.22\ M

Which measure of a gas does the expression
Usimov [2.4K]

Answer:

A. volume

Explanation:

Generally the equation for the  ideal gas  is mathematically given as  

PV=nRT

Where  

P=pressure  

V=volume  

R=gas constant  

n=Number of Moles  

T=Temperature

 

Therefore  

V=nRT/P  

Option A
