<h3>
Answer:</h3>
70.906 g
<h3>
Explanation:</h3>
We are given;
- Atoms of Chlorine = 1.2 × 10^24 atoms
We are required to calculate the mass of Chlorine
- We know that 1 mole of an element contains atoms equivalent to the Avogadro's number, 6.022 × 10^23.
- That is , 1 mole of an element = 6.022 × 10^23 atoms
- Therefore; 1 mole of Chlorine = 6.022 × 10^23 atoms
But since Chlorine gas is a molecule;
- 1 mole of Chlorine gas = 2 × 6.022 × 10^23 atoms
But, molar mass of Chlorine gas = 70.906 g/mol
Then;
70.906 g Of chlorine gas = 2 × 6.022 × 10^23 atoms
= 1.20 × 10^24 atoms
Thus;
For 1.2 × 10^24 atoms ;
= ( 70.906 g/mol × 1.2 × 10^24 atoms ) ÷ (1.20 × 10^24 atoms)
<h3>= 70.906 g </h3>
Therefore, 1.20 × 10^24 atoms of chlorine contains a mass of 70.906 g

Yes because when a ball has more air in it , it’s most likely to bounce higher than an inflated or one with less air because of the pressure which somehow changes the material of the ball to be less inflated and squishy
Answer:
This reaction is an hydration of alkenes and the major product is 3-ethyl-2-heptanol
Explanation:
In this reaction in the first step water is the nuclophile and the alkene is the electrophile. Then, the carbanion is the nucleophile and attacks a proton from the water forming the respective alcohol. This carbanionic compound is a reaction intermediary. You can see the mechanism in the picture.
Is that carbanionic compound who explained the major product because the more substituted carbanion the most stable intermediary. Thus, the 3-ethyl-2-heptanol intermediary is the most stable and this product is the major one.
I hope it helps!
Answer:
None of the above.
Explanation:
A nebula: A star forms from massive clouds of dust and gas in space, also known as a nebula. Protostar: As the mass falls together it gets hot. Main sequence star. Red giant star. White dwarf. Supernova, and the Neutron star or black hole are all apart of the life cycle of Sol.
Answer: Activation energy
Explanation:
In a chemical reaction, the reactants contains particles which must collide in order for a reaction to occur. The rate of reaction depends on the frequency of effective collision between the reacting particles. Effective collision are those that result in reactions, which when they occur the colliding particles become activated with increased kinetic energy.
This energy must exceed a particular energy barrier for a particular reaction if the reaction must take place. This energy barrier that must be overcome before a reaction takes place is known as the ACTIVATION ENERGY.
To explain further, when two particles or molecules A and B come in contact with each other, for a reaction to take place, they must collide with a sufficient force to break the bond that exists between them. The minimum combined kinetic energy these reactant particles must possess in order for their collision to result in a reaction is called the activation energy.
