Does sodium have a positive or negative charge after ionization?
lions [1.4K]
Sodium Chloride also known as table salt, the sodium has a positive charge and the chloride a negative so after ionization that leaves you with two negative charges because it takes the salt away. possibly disforming the atoms.<span />

How many particles of Na are there in 1.43g of a molecular compound with a Molar mass of 23g?
Olin [163]

Answer:

3.74 x 10²² particles

Explanation:

Given parameters:

Mass of compound  = 1.43g

Molar mass of compound  = 23g

Unknown:

Number of particles of sodium = ?

Solution:

To find the number of particles of Na in the compound, we need to obtain the mass of sodium from the total mass given;

          Mass of sodium  = \frac{molar mass of Na}{molar mass of compound} x mass of sample

                                      = \frac{23}{23}  x 1.43g

                                       = 1.43g

Now find the number of moles of this amount of Na in the sample;

          Number of moles  = \frac{mass}{molar mass} = \frac{1.43}{23}  = 0.062mole

Now;

                    1 mole of substance  = 6.02 x 10²³ particles

                       0.062 mole of substance  =  0.062 x 6.02 x 10²³ particles

                                                                     = 3.74 x 10²² particles

Why does one beach have purple sand and another beach have pink sand?
Gnesinka [82]
Ok so I’m going to break it up so it’s a bit easier to read through:

The colours are from the different rocks and minerals that make up the sand.

The little fragments of rock come from for example surrounding mountains.

It could also because sand is simply the product from erosion of the rocks rubbing each other under the action of the waves.

So if the bottom of the ocean is made of black lava for example in Hawaii, there’s a good chance of the sand being black.

In California, the sand usually looks white because it has minerals like quartz and pieces of shell that are made of calcium carbonate.

Hope this helps :)
