Question 2

Chemistry
1 answer:
Alenkinab [10]3 years ago

Answer:

1.53 atm

Explanation:

From the question given above, the following data were obtained:

Volume = constant

Initial pressure (P₁) = stp = 1 atm

Initial temperature (T₁) = 273 K

Final temperature (T₂) = 144 °C = 144 °C + 273 = 417 K

Final pressure (P₂) =?

Since the volume is constant, the final pressure can be obtained as follow:

P₁ / T₁ = P₂ / T₂

1 / 273 = P₂ / 417

Cross multiply

273 × P₂ = 417

Divide both side by 273

P₂ = 417 / 273

P₂ = 1.53 atm

Therefore, the final pressure (i.e the pressure inside the hot water bottle) is 1.53 atm.

Allisa [31]

Explanation:

(1).  It is known that in a reaction equation, reactants are placed or written on left hand side and products are written on the right hand side.

For example, N_{2} + 3H_{2} \rightarrow 2NH_{3}

Hence, in a reaction equation you start with the reactants and end up with the products.

(2).  The number of atoms in a reaction will remain the same because according to the law of conservation of mass, mass of reactants will be equal to the mass of products.

Therefore, number of atoms on the reactant side will be equal to the number of atoms on product side.

Convert 190 mmHg to a) kilopascals<br> b) atmospheres
DochEvi [55]
<h3>Answer:</h3>

#a. 25.33 kPa

#b. 0.25 atmospheres

<h3>Explanation:</h3>
  • Pressure may be measured using several units which include pascals, atmospheres, mmHg and kilopascals.
  • These units of measuring pressure may be converted from one unit to another using a conversion factor.

For example;

1 kPa = 7.5 mmHg

Thus, in our case,

#a. To convert 190 mmHg to kPa

we divide 190 mmHg by 7.5 mmHg

   = 190 mmHg ÷ 7.5 mmHg

  = 25.33 kPa

Hence, 190 mmHg is equivalent to 25.33 kilopascals

Another conversion factor is;

1 atm = 760 mmHg

Therefore, in our case,

#b. To convert 190 mmHg to atmospheres

we divide 190 mmHg by 760 mmHg

That is; 190 mmHg ÷ 760 mmHg

            = 0.25 atm

Thus, 190 mmHg is equivalent to 0.25 atm
