Suspensions

Explanation:

Suspensions are heterogeneous mixtures that contains large particles that can settle out or be filtered.

  • Suspensions are mixtures of small insoluble particles of a solid in a liquid or gas.
  • Examples are:
  1.  powdered chalk in water
  2. muddy water
  3. harmattan

The particles in suspension can settle on standing

The ion p3− has _____ protons and _____ electrons. enter your answers as integers separated by a comma.'
katrin2010 [14]

The symbol P is for phosphorus having atomic number 15. That means it has 15 protons and 15 electrons in its neutral state.

The given symbol P^{3-} has a -3 charge that means it has gained 3 electrons so, the number of electrons in the P^{3-} is: 15+3 = 18. The number of protons will remain same that is the number of protons = 15.

So, the ion P^{3-} has 15 protons and 18 electrons that gives 15-18=-3 charge on the P^{3-} ion.

So, the answer is 15 , 18.

How many moles of LiOH are required to make 4.2 liters of a 0.98 M
ASHA 777 [7]

Answer:

4.12 mol  

Explanation:

Given data:

Moles of LiOH  required = ?

Volume of solution = 4.2 L

Molarity of solution = 0.98 M

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

we will calculate the moles from above given formula.

0.98 M = number of moles / 4.2 L

0.98 M × 4.2 L = number of moles

Number of moles = 0.98 M × 4.2 L

Number of moles = 4.12 mol     (M = mol/L)
