Explanation:

<em>The</em><em> </em><em>answer</em><em> </em><em>is</em><em> </em><em>directly</em><em> </em><em>proportional</em><em>, </em><em>because</em><em> </em><em>when</em><em> </em><em>there</em><em> </em><em>is</em><em> </em><em>more</em><em> </em><em>concentration</em><em> </em><em>their</em><em> </em><em>will</em><em> </em><em>more</em><em> </em><em>reactants</em><em> </em><em>to</em><em> </em><em>react</em><em> </em><em>fast</em><em> </em><em>diring</em><em> </em><em>the</em><em> </em><em>chemical</em><em> </em><em>reaction</em><em> </em><em>which</em><em> </em><em>increases</em><em> </em><em>the</em><em> </em><em>rate</em><em> </em><em>of</em><em> </em><em>chemical</em><em> </em><em>reaction</em><em>. </em>

<em>So</em><em>,</em><em> </em><em>we</em><em> </em><em>can</em><em> </em><em>state</em><em> </em><em>that</em><em> </em><em>the</em><em> </em><em>relationship</em><em> </em><em>between</em><em> </em><em>them</em><em> </em><em>are</em><em> </em><em>directly</em><em> </em><em>proportional</em><em>. </em>

A sample of gas has a volume of 400 liters when its temperature is 20.C and its pressure
ikadub [295]

Answer:

V₂ = 145.35 L

Explanation:

Given data:

Initial volume = 400 L

Initial pressure = 300 mmHg (300/760 =0.39 atm)

Initial temperature = 20 °C (20 +273 = 293 K)

Final temperature = 273 K

Final volume = ?

Final pressure = 1 atm

Solution:

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

P₁V₁/T₁ = P₂V₂/T₂  

V₂ = P₁V₁T₂  /T₁ P₂

V₂ =  0.39 atm × 400 L × 273 K / 293 K × 1 atm

V₂ = 42588 atm.L.K /293 K.atm

V₂ = 145.35 L

If you add 14.22ml of 2.97m hcl (42.2mmol) to an antacid, then neutralize the excess acid with 5.00ml of 0.1055 m naoh (0.528mmo
Vinvika [58]

Given data:

Volume of HCl = 14.22 ml

Molarity of HCl = 2.97 M

mmoles of HCl = 14.22 * 2.97 = 42.2 mmoles

Volume of NaOH = 5.00 ml

Molarity of NaOH = 0.1055 M

mmoles of NaOH = 5.00 *.1055 = 0.5275 mmoles

Since HCl and NaOH combine in a 1:1 ratio

# moles of NaOH = # moles of excess HCl that is neutralized = 0.5275 moles

Now, the total moles of HCl taken = # mmoles HCl neutralized by antacid + # mmoles of excess HCl

42.2 = mmoles HCl neutralized by antacid + 0.5275

Therefore,

mmoles of HCl neutralized by antacid = 42.2 - 0.5275 = 41.6725 mmoles = 41.7 mmoles

Based on the kinetic molecular theory (KMT), which statement is true?
nataly862011 [7]

Statement 1 is false because heat is the movement of molecules.

Statement 2 is true because matter is composed of elementary particles which are VERY small.

Statement 3 is false because the kinetic energy of a particle determines its heat and it is impossible for a particle to be completely motionless.

Statement 4 is false because neutrons do not have a charge and make up a large portion of all matter.
