In the nucleus, a sodium atom (Na) has 11p+ and 12 nºo. How would you write the
Hatshy [7]

Answer:

Na⁺

Explanation:

Given parameters:

         Number of protons = 11

         Number of neutrons  = 12

Writing the expression based on sodium ion that lost one electron;

In a neutral sodium atom, the number of protons and electrons are the same. Number of protons are the the positively charged particles in an atom.

Number of electrons are the negatively charged particles.

If an atom loses electron for instance sodium:

           Number of electrons  = 10

           Number of protons  = 11

Charge on the atom  = 11  - 10  = 1+

So, the symbol of the atom is Na⁺

How many hydrogen atoms are in 3.90 mol of ammonium sulfide?
lozanna [386]

Answer:

First, the number of ammonium sulfide molecules should be calculated:

N = NA × n,

where NA - the Avogadro number, n - number of moles.

N (ammonium sulfide) = 6.022 × 1023 × 8.5 mol = 51.187 × 1023.

The moelcular formula of ammonium sulfide is (NH4)2S. It means that each molecule contains 8 hydrogen atoms.

As a result, 8.5 mol of (NH4)2S contain:

51.187 × 1023 × 8 = 41 × 1024 hydrogen atoms.

Answer: 41 × 1024 hydrogen atoms

Describe the process of evaporation.
saveliy_v [14]

Hopefully this helps, this is basically simplified but you could ask me for a more detailed explanation. But evaporation works by water on the ground(puddles, lakes, etc) turn into a vapor, which means the water tunrs into gas, which is invisible. Then that water goes up and is stored in the clouds which would then become water and fall into a puddle and the cycle repeats! Hope this Helped!

How many atoms are present in 0.529 moles of Li?
nirvana33 [79]

Answer:

<h2>3.18 × 10²³ atoms</h2>

Explanation:

The number of atoms can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 0.529 × 6.02 × 10²³

We have the final answer as

<h3>3.18 × 10²³ atoms</h3>

Hope this helps you
