Chemistry
1 answer:
GREYUIT [131]3 years ago
3 0

Answer:

Atoms were impenetrably hard, meaning they could not be divided. In Greek, the prefix "a" means "not" and the word "tomos" means cut. Our word atom therefore comes from atomos, a Greek word meaning uncuttable.

What happens when chlorine forms an ion?
zmey [24]

The chlorine usually forms a Chloride ion.

The Chlorine gains an electron leaving it 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.

What do you mean by Chlorine forming an ion?

Chlorine has one electron when it forms an ion to be an anion with a charge of -1. The charge of an ion, and thus the number of electrons the atom will gain or lose. If an atom has less than four valence electrons, it will lose them to become a cation.

The chloride ion is the anion  Cl− which is formed facilitating important chemical reactions coupled with its usage in the everyday world.

In a recent Grand Prix, the winner completed the race with an average speed of 299.8 km/h. What was his speed in miles per hour,
scoundrel [369]

Answer :

(a) The speed is, 186.287 mi/hr

(b) The speed is, 83.277 m/s

(c) The speed is, 273.22 feet/s

Explanation :

(a) We are given the speed is, 299.8km/hr

As we know that,

1km=\frac{1}{1.60934}mi

By using both the conversion, we get:

299.8km/hr

\Rightarrow \frac{299.8km}{1hr}\times \frac{1mi}{1.60934km}

\Rightarrow 186.287mi/hr

The speed is, 186.287 mi/hr

(b) We are given the speed is, 299.8km/hr

As we know that,

1km=1000m

and,

1hr=3600s

By using both the conversion, we get:

299.8km/hr

\Rightarrow \frac{299.8km}{1hr}\times \frac{1000m}{1km}\times \frac{1hr}{3600s}

\Rightarrow 83.277m/s

The speed is, 83.277 m/s

(c) We are given the speed is, 299.8km/hr

As we know that,

1km=3280.84feet

and,

1hr=3600s

By using both the conversion, we get:

299.8km/hr

\Rightarrow \frac{299.8km}{1hr}\times \frac{3280.84feet}{1km}\times \frac{1hr}{3600s}

\Rightarrow 273.22feet/s

The speed is, 273.22 feet/s
