Answer:

1520mmHg

Explanation:

Data obtained from the question include:

V1 (initial volume) = 600 mL

P1 (initial pressure) = 760 mmHg

V2 (final volume) = 300 mL

P2 (final pressure) =.?

Using the Boyle's law equation P1V1 = P2V2, the final pressure of the gas can easily be obtained as shown below:

P1V1 = P2V2

760 x 600 = P2 x 300

Divide both side by 300

P2 = (760 x 600) /300

P2 = 1520mmHg

The final pressure of the gas is 1520mmHg

Which of the following is the correctly balanced chemical equation for the reaction of Ca(OH)2 and HNO3?
sleet_krkn [62]

Answer : The correct option is D.

Explanation :

Balanced chemical equation : It is defined as the mass or component of each atom should be equal on both sides of the equation.

The balanced chemical equation for the reaction of Ca(OH)_2 and HNO_3 is,

Ca(OH)_2+2HNO_3\rightarrow 2H_2O+Ca(NO_3)_2

So, the correct option is D.

For the following gases, correct the volumes to the conditions indicated. A.654 cm3 at 6 degrees Celsius and 65.3 kPa to 4 degre
leva [86]

Initial pressure of the gas = 65.3 kPa  

Initial volume of the gas = 654 cm³

Initial temperature of the gas = 6⁰C = 273 + 6 = 279 K

Final pressure of the gas = 108.7 kPa

Final temperature of the gas = 4⁰C = 273 + 4 = 277 K

Using the combined gas law for ideal gases:

P₁V₁/T₁ = P₂V₂/T₂  

where P₁, V₁ and T₁ are the pressure, volume and temperature for the initial state and P₂, V₂ and T₂ are the pressure, volume and temperature for the final state.

Plugging the given data into the combined gas law we have,

(65.3 kPa x 654 cm³) / (279 K) = (108.7 kPa x V₂)/(277 K)

V₂ = (65.3 kPa x 654 cm³ x 277 K) / (279 K x 108.7 kPa)

V₂ = 390.1 cm³

When a neat, ordered chemical is changed into a more disordered chemical, there is an increase in what?
polet [3.4K]
When a neat, ordered chemical is change into a more disordered chemical, then there is an increase in ENTROPY.
Entropy refers to the degree of disorderliness in a reacting system. The degree of entropy is considered to be zero, when there is no disorderliness. The degree of entropy increases as the disorderliness increases.  <span />

If 70 mL of a 0.4 M Ba(NO3)2 solution is mixed with excess amount of a Na2CO3 solution, what is the theoretical yield of the pre
Sindrei [870]

The theoretical yield of BaCO3 is 5.5

<h3>What is theoretical yield?</h3>

The theoretical yield is the yield calculated from the stoichiometry of the reaction. The equation of the reaction is;

Ba(NO3)2(aq) + Na2CO3 (aq) ------> BaCO3(s) + 2NaNO3(aq)

Number of moles of limiting reactant: 0.4 M × 70/1000 = 0.028 moles

Since the reaction is 1:1,om;y 1 mole of BaCO3 is formed. Hence, mass of BaCO3 = 0.028 moles × 197 g/mol = 5.5g
