Suppose you are riding in a car. Describe your motion relative to the car, the road and the sun
Answers
The relative motion of a person riding in a car has been stationary with car, uniform constant with road, and sun.
The motion has been defined as the change in position of an object with respect to another.
Relative motion
The relative motion has been observed by considering an object at rest and assuming the displacement with the another.
The relative motion has been assessed from car, thus car has been assumed at rest.
- The relative motion of the person ridding in the car with respect to the car has been stationary. It has been no motion of person with respect to car.
- The relative motion of the person riding the car with the road has been constant. The car has been moving along the road in the motion.
- The relative motion of person riding car with the sun has been constant as there has no change in the motion of the sun as soon as we are riding in straight path.
Thus, the relative motion of a person riding in a car has been stationary with car, uniform constant with road, and sun.

Every atom of the same
element has the same
atomic number.
Answers
Answer: True
Explanation: Every atom of the same element has the same atomic number of number of protons in its core. This is why chemists say that an atom is defined by its atomic number of the number of protons.
Unlike neutrons and electrons, you can't change protons. You can change the number of neutrons and it will still be the same element, but one is going to be a little bit heavier or a little bit lighter than another.
In addition, you can change electrons which creates
ions or charged atoms.
However, you can't change the protons.
For example, hydrogen has 1 proton in its nucleus no matter what and helium has 2 protons in its nucleus no matter what and so on.
Final answer:
The statement is true. Every atom of the same element has the same atomic number, which is the number of protons in an atom's nucleus. This is a unique value defining an element.
Explanation:
The statement 'Every atom of the same element has the same atomic number' is True. The atomic number of an element is unique to that element and determines its position on the Periodic Table. It represents the number of protons in an atom's nucleus and is the fundamental property that defines an element. All atoms of the same element will have the same number of protons, and therefore the same atomic number.

Which variables are given?
Answers
0.24 moles of oxygen must be placed in a 3.00 L container to exert a pressure of 2.00 atm at 25.0°C.
The variables given are Pressure, volume and temperature.
Explanation:
Given:
P = 2 atm
V = 3 litres
T = 25 degrees or 298.15 K by using the formula 25 + 273.17 = K
R = 0.082057 L atm/ mole K
n (number of moles) = ?
The equation used is of Ideal Gas law:
PV = nRT
n =
Putting the values given for oxygen gas in the Ideal gas equation, we get
n =
= 0.24
Thus, from the calculation using Ideal Gas law it is found that 0.24 moles of oxygen must be placed in a container.
Ideal gas law equation is used as it tells the relation between temperature, pressure and volume of the gas.

Answers
Answer:
(2) parts per million
Explanation:
Concentration of a solution can be expressed in terms of parts-per-million (ppm).
ppm is usually used in the context of measuring very small concentrations particularly the amount of contaminants. It represents 1 part of the contaminant in 100000 parts of the total.
It is expressed as:
1 ppm = 1 mg / L
1 ppm = 1 mg/ Kg
