Chemistry
1 answer:
spayn [35]3 years ago

Answer:

a)

Explanation:

When finding the element based on its electronic configuration the subscripts gives the number of electrons in the element.

In the given example total number of subscripts are 16. This means the element has 16 electrons which is equal to the atomic number of the element. hence, the element is Sulphur.

Here, s, p, d, and f are orbitals. So, as per the EC given, 3p orbital has 4 electrons in it. Hence, option (a) is correct.

Since, s, p, d, and f are orbitals and not shells, subshells. Therefore, other options are incorrect.

DanielleElmas [232]

Answer:

=1.36kg

Explanation:

First heat is absorbed to melt the ice- latent heat of fusion of ice then heat is absorbed to raise the temperature to 373K

The specific heat capacity of water is 4.187kJ/kg/K while  the latent heat of fusion of ice is 2230kJ/kg/K.

Letting the mass of the ice to be =x

x×2230kJ/kg/K + x×4.187kJ/kg/K×100K= 3600kJ

2230x+418.7x=3600

2647.8x=3600

x=1.36 kg

Can someone Summarize how the suns gravity affects the planets please.
egoroff_w [7]

The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.

Toothpaste contains Sodium fluoride which is used to prevent tooth decay. How many grams are in 1 mole NaF?
nikitadnepr [17]

The answer is 42 grams of NaF are there in 1 mole.

<h3>What is a mole ?</h3>

A mole is defined as 6.022 × 10²³ atoms, molecules, ions, or other chemical units.

and the molar mass of a substance is defined as the mass of 1 mole of that substance, expressed in grams per mole.

It is equal to the mass of 6.022 × 10²³ atoms, molecules, or formula units of that substance.

Molar Mass , i.e. mass of 1 mole of NaF is sum of molar mass of Na and F

23 + 19

42 grams

Therefore 42 grams of NaF Sodium-fluoride are there in 1 mole.
