Answer:

B. The temperature of the liquid will rise.

Explanation:

As the molecules present in the beaker will increase their speed that will result in rise in the temperature of the liquid.

This is so because as the movement or motion of molecules increases, atoms vibrate faster, and its collision with each other and with the wall of the beaker increases that causes a rise in the temperature of the liquid. If the molecules move slowly then the temperature will fall down.

Hence, the correct answer is "B. The temperature of the liquid will rise.".

An organic acid is composed of carbon (45.45%), hydrogen (6.12%), and oxygen (48.44%). Its molar mass is 132.12 g/mol. Determine
Andreas93 [3]

Answer:

C4H8O4

Explanation:

To determine the molecular formula, first, let us obtain the empirical formula. This is illustrated below:

From the question given, we obtained the following information:

C = 45.45%

H = 6.12%

O = 48.44%

Divide the above by their molar mass

C = 45.45/12 = 3.7875

H = 6.12/1 = 6.12

O = 48.44/16 = 3.0275

Divide by the smallest

C = 3.7875/3.0275 = 1

H = 6.12/3.0275 = 2

O = 3.0275/3.0275 = 1

The empirical formula is CH2O

The molecular formula is given by [CH2O]n

[CH2O]n = 132.12

[12 + (2x1) + 16]n = 132.12

30n = 132.12

Divide both side by the coefficient of n i.e 30

n = 132.12/30 = 4

The molecular formula is [CH2O]n = [CH2O]4 = C4H8O4

For a gas sample containing equimolar amounts of carbon monoxideand heliumat 300 K, heliumhas _____________average speed and ___
igor_vitrenko [27]

Answer:

Option C (a higher; the same) is the appropriate response.

Explanation:

Given:

Temperature,

T = 300 K (both N_2 and H_2)

As we know,

Average speed of a molecule,

⇒ \bar v=\sqrt{\frac{8RT}{\pi  M} }

Thus, the average speed of N_2 will be lower as its molar mass is greater than H_2.

Now,

⇒ Average \ kinetic \ energy = \frac{3}{2} \ KT (not depend on molar mass)

Hence, it will be the same.

The other three alternatives aren't connected to the scenario given. So the above is the correct answer.
