Answer:

Attached in the photo.

Explanation:

Hello,

The answers in the attached photo. Just three things:

- In the second point a parenthesis is missing to properly understand the molecule (after the oxygen), nevertheless, I assumed it was an ether.

- In the sixth point, there's a missing hydrogen for it to be an ether as well.

- In the tenth point the second parenthesis is not clear, it seems there's a missing subscript, nevertheless I draw it assuming complete octates.

Best regards.

A compound is 40% carbon, 6.7% hydrogen, and 53.3% oxygen. What is the empirical formula? (4 points)
Elis [28]

Answer:

CH2O

Explanation:

Dividing by the atomic masses:

40 / 12 = 3.333

6.7 / 1 = 6.7

53.3 / 16 = 3.331

The ratios are

3.333/ 3.333 : 6.7 / 3.333 : 3.331/3.333

= 1:2:1.

So it is CH2O.

maxonik [38]

Answer:

Convection

Explanation:

Convection is a mode of heat transfer that involves the actual movement of particles. In this case the particles are air particles.

Since hot air is less dense, it is pushed up by the denser cool air. This process may continue indefinitely and a convection current is set up.

What is the approximate temperature of 1.4 moles of a gas with a pressure of 3.25 atmospheres in a 4.738-liter container
attashe74 [19]

Answer:

134K

Explanation:

Using the ideal gas law equation;

PV = nRT

Where;

P = pressure (atm)

V = volume (Litres)

n = number of moles (mol)

R = gas constant (0.0821 Latm/Kmol)

T = temperature (K)

Based on the information provided, n = 1.4moles, P = 3.25atm, V = 4.738L, T = ?

3.25 × 4.738 = 1.4 × 0.0821 × T

15.3985 = 0.11494T

T = 15.3985/0.11494

T = 133.969

Approximately;

T = 134K
