There are three stable atoms of Argon (Atomic Number 18): Argon-36, Argon-38 andArgon-40. What would the atoms of these isotopes have in common? What would
be different about their atoms? (4 points)
HELP ASAP

Answers

Answer 1
Answer:

On the periodic table, argon has an average atomic weight of 39.948 amu. This number is really near 40. This suggests that Ar-40 is the isotope of argon (Ar) that is most prevalent in the natural world.

What characteristics do argon-36, argon-38, and argon-40 share?

If all three argon atoms are neutral, they would each contain 18 protons and 18 electrons. In comparison to one another, the three isotopes will each have a distinct number of neutrons (18, 20, and 22 neutrons respectively).

Why is potassium a 39 positioned before argon, atomic number 40, in the current periodic table?

Atomic number, not atomic mass, is used to categorise the elements. As the atomic number of argon (18) is less than that of potassium (19)

If an element, X, can form an oxide that has theformula X2O3, then element X would most likely be located on the Periodic Table in the same group as(1) Ba (3) In
(2) Cd (4) Na

Answers

Answer: (3) In

Explanation: As the given compound is X_2O_3, it can be said that X has a valency of 3.

1)Barium (Ba): Atomic no: 56: Xe6s^2 : In order to complete its octet, it needs to donate 2 electrons, and thus the valency is 2.

2) Cadmium (Cd) : Atomic no: 48: Kr5s^24d^(10) : In order to complete its octet, it needs to donate 2 electrons, and thus the valency is 2.

3) Indium (In): Atomic no: 49: Kr5s^25p^(1) : In order to complete its octet, it needs to donate 3 electrons, and thus the valency is 3.

4) Sodium (Na): Atomic no: 11: Ne3s^1 : In order to complete its octet, it needs to donate 1 electron, and thus the valency is 1.

So the given element could only belong to the group containing Indium (In) as all the elements in the same group exhibit similar valency.
In! This is becasue it has a valency of 3

How much CaCl2, in grams, is needed to make 2.0 L of a 3.5M solution?

Answers

find the number of moles: 2•3.5=7 moles

and do dimensional analysis. to convert moles of solution to moles of cacl2 and moles of cacl2 to grams of cacl2 (molar mass)

If you use half as many moles of reactant *then: you'll make twice as much money
the reaction won't happen 
the reaction will release half as much heat 
the reaction will absorb heat

Answers

The reaction will release half as much heat

Answer:

The reaction will release half as much heat

Explanation:

Because there are less reactants the amount of energy released will decrease. Because the reactants halves the amount of heat released also halves.

The two factors that affect the magnitude of the force are

Answers

The two factors that affect the magnitude of the force are magnitude of force and distance of line of action of force.

What is force?

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.
