___________________is the rate that an object moves in a certain direction. Question 3 options:

Speed

Displacement

Direction

Velocity

Answers

Answer: Velocity

Explanation:

i just took the quiz for k12

Velocity is the rate at that an object moves in a certain direction. The correct option is d.

What is velocity?

The directional speed of an item in motion, as measured by a specific unit of time and observed from a certain point of reference, is what is referred to as velocity. A vector is a velocity. It comprises both magnitude and direction.

The size of velocity is speed. In still air, a particle gravitationally settles and quickly reaches its terminal velocity. The term "settling velocity" refers to a particle's final speed in a still fluid (also known as the "sedimentation velocity").

The particle settling velocity in the foreshore region plays a significant role in understanding fluctuations in the hydraulic regime and interactions between sediment and fluid in the surf zone.

Therefore, the correct option is d, Velocity.

Which of the following is the smaller atom: magnesium or chlorine?

Answers

Answer:

Chlorine atoms are smaller

Explanation:

Magnesium have more electrons than chlorine.

Answer: Chlorine

Explanation: Since chlorine's 17 protons are greater than magnesium's 12 protons, chlorine will have a greater effective nuclear charge to draw chlorine's valence electrons closer to the nucleus and, thus, chlorine is expected to have the smaller atomic radius, while magnesium with the lower effective nuclear charge is expected to have the larger atomic radius.

     

A cold can of soda is taken out of the refrigerator. It slowly warms up until it is at room temperature. Once the soda has warms up, it has more thermal energy than it had in the refrigerator. Where did this additional thermal energy come from?

Answers

Answer:

See explanation

Explanation:

We know that the thermal energy of a substance largely depends on the temperature of the body. This implies that the hotter a substance is, the greater its thermal energy and vice versa.

When you bring a cold can of soda out of the refrigerator, the molecules of air at room temperature gradually loose energy to the can and condense around it. This transfers thermal energy from the air particles to the molecules in the cold can of soda and the soda warms up pretty soon!

When energy is released by the pack, what happens to the energy of the surroundings (outside the pack)?
a. The energy increases
b. The energy decreases
c. The energy stays the same

Answers

Answer:

a

Explanation:

i hope that's correct

The energy of the surroundings (outside the pack) will:

a. The energy increases, when energy is released.

Energy in the surroundings:

Energy is delivered to create bonds, which is the reason the enthalpy change for it is positive to break bonds. Energy is expected to break bonds. Particles are a lot more joyful when they are "wedded" and discharge energy since it is simpler and more steady to be seeing someone.

When energy is released, the energy in the surroundings will increase.

Thus, option a is correct.

Explanation:

how many molecules of water are produced when 3.14 grams of ammonium nitrate are decomposed

Answers

Answer:

See the last entry

Explanation:

Remark

Ammonium Nitrate decomposes as follows.

NH4NO3 → N2O + 2H2O

If this does not agree with the reaction you have, let me know.

Step One

Find the molecular Mass of Ammonium Nitrate.

N =  1 * 14  =  14

H =  1 * 3 =     3

N =  1 * 14     14

O3 = 3*16  = 48

Molar Mass =69

Note: the masses used are approximate. Every periodic table is different. When you answer this question use the masses on your periodic table. My numbers are just guides.

Step Two

Find the number of mols in Ammonium Nitrate.

Formula

mols = given mass / molar mass

Givens

given mass = 3.14

Molar Mass = 69

mols  = 3.14 / 69

mols = 0.0455

Step 3

moles of water.

1 mol of Ammonium Nitrate = 2 mols of water

0.0455 mols of Ammonium Nitrate = x mols of water

x = 2* 0.0455 mols of water.

x = 0.091 mols of water

Step 4

Find the molecules of water.

1 mol of water = 6.02*10^23 molecules of water

0.091 mol water= x

x = 0.091 * 6.02*10^23

x = 5.48 * 10^23
