Drugs are substances that change a person's mental or physical state. They can affect the way your brain works, how you feel and behave, your understanding and your senses. This makes them unpredictable and dangerous, especially for young people. The effects of drugs are different for each person and drug.

Select ALL correct answers. The contact force is caused by: A. Atoms randomly crashing into each other B. The charged particles
Inessa [10]

Answer:

A. Atoms randomly crashing into each other

E. The force of one object pushing against the force of another object.

Explanation:

Forces can be classified into two categories based upon the the mode of transfer or application:

1. Contact forces

2. Non-contact forces

Contact forces are the ones which require the physical contact of the matter to get transferred and tend to create the affect. Whereas non-contact forces have the field property which transfers the affect of force from one point to another without any physical contact of the matter or the medium.

  • Atoms crashing onto each other have some mass and velocity which upon collision impacts the other atoms exerts a contact force.
  • The interaction between the charged particles due to their charges is always due to the electric field be it electron or proton, be it within an atom or out of an atom.
  • The force between any two objects pushing or pulling each other is also possible only due to contact.

Diethyl ether (C2H5 )2O vaporizes at room temperature. If the vapor exerts a pressure of 233 mm Hg in a flask at 25 °C, what is
Svet_ta [14]

Answer: The density of the given vapor is 0.939 g/L.

Explanation:

Given: Pressure = 233 mm Hg (1 mm Hg = 0.00131579 atm) = 0.31 atm

Temperature = 25^{o}C = (25 + 273) K = 298 K

According to the ideal gas equation,

PV = \frac{m}{M}RT

where,

P = pressure

V = volume

m = mass

M = molar mass

R = gas constant = 0.0821 L atm/mol K

T = temperature

This formula can be re-written as follows.

PM = \frac{m}{V}RT    (where, Density = \frac{mass (m)}{Volume (V)} )

Hence, formula used to calculate density of diethy ether (molar mass = 74.12 g/mol) vapor is as follows.

d = \frac{PM}{RT}

Substitute values into the above formula as follows.

d = \frac{PM}{RT}\\= \frac{0.31 atm \times 74.12 g/mol}{0.0821 L atm/mol K \times 298 K}\\= \frac{22.9772}{24.4658}\\= 0.939 g/L

Thus, we can conclude that the density of the given vapor is 0.939 g/L.

What element has a total of 3 p-sublevel electrons?
den301095 [7]

Elements with three p-electrons....


That would be N, P, As, Sb, and Bi -- elements in group 15


For example, energy diagram showing "empty" orbitals up through the 3p.

3s __

.....2p __ __ __

2s __

1s __


Energy diagram of phosphorous showing three unpaired electrons in 3p-sublevel

.....3p ↑_ ↑_ ↑_

3s ↑↓

.....2p ↑↓ ↑↓ ↑↓

2s ↑↓

1s ↑↓


According to Hund's rule, the electrons singly occupy the p-orbitals, and all have the same spin.

Cerrena [4.2K]

Answer:

Your answer will be 118 cm^3.

Explanation:

V1/T1 = V2/T2, so V2 = V1T2/T1. 60C = 333K and 120C = 393K.

V2 = (100cm3)(393K)/(333K) = 118 cm3
