Naming of Ionic compounds.

  1. Name the cation first and then write its oxidation number in roman numerical.
  2. Then name the anion or polyatomic ions without writing any prefix of the number of atoms present in it.
  3. The name of the anion should have a suffix '-ide' like for chlorine, the name will be chloride etc..
  4. For polyatomic ions, the suffix used will be '-ate' like for SO_4^{2-} the name will be sulfate etc..

Name of the given ionic compound is Gallium (III) Sulfate.

A student wants to prepare a solution of cobalt(II) fluoride with a known molarity.
swat32

Answer:

\large \boxed{\text{1.52 g}}

Explanation:

1. Calculate the moles of CoF₂ needed

n = \text{0.100 L} \times \dfrac{\text{0.157 mol}}{\text{1 L}}  = \text{0.0157 mol}

2. Calculate the mass of CoF₂

m = \text{0.0157 mol} \times \dfrac{\text{96.93 g}}{\text{1 mol}}  = \text{1.52 g}\\\\\text{ The student must measure out $\large \boxed{\textbf{1.52 g}}$ of cobalt(II) fluoride}

How many molecules are in 42.3g sample of water
Helga [31]

Answer:

The number of molecules is 1.4140*10^24 molecules

Explanation:

To know the number of molecules, we need to determine how many moles of water we have, water has molar mass of 18.015g/mol

This means that one mole of water molecules has a mass of 18.015g.

42.3g * 1 mole H2O/18.015g

= 2.3480 moles H2O

We are using avogadros number to find the number of molecules of water

2.3480 H2O * 6.022*10^ 23moles/ 1mole of H2O

That's 2.3480 multiplied by 6.022*10^23 divided by 1 mole of H2O

Number of molecules = 1.4140 *10^24 molecules

What is the weight of dark matter​
Ostrovityanka [42]

Answer:

Knowing this, researchers from the University of Southern Denmark decided to investigate the size of these hypothetical hidden particles. According to the team, dark matter could weigh more than 10 billion billion (10^9) times more than a proton.

Explanation:

If this is true, a single dark matter particle could weigh about 1 microgram, which is about one-third the mass of a human cell (a typical human cell weighs about 3.5 micrograms), and right under the threshold for a particle to become a black hole.
