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:
- powdered chalk in water
- muddy water
- harmattan
The particles in suspension can settle on standing

To neutralize 1.65 LiOH , how the HCL needed is calculated as follows
calculate the moles of LiOH been neutralized
1.65/23.95 = 0.069 moles
write the reaction equation
HCl + LiOH = LiCl +H2O
by use of mole ratio between HCL to LiOH that is 1:1 the the moles of HCl is therefore = 0.069 moles
The HC needed is therefore = moles/ molarity
= 0.069/0.150 = 0.46 liters
Answer: iodine 131 iodine 132 isotopes
Explanation:
Answer:
Explanation:
<u>1. Molar masses of the two compounds</u>
i) Vitamin C:
Formula: C₆H₈O₆
ii) Sucralose
<u>2. Molarity of the solution:</u>
The osmotic pressure is a colligative property which can be calculated using the following equation:
Where:
- Π is osmotic pressure (atm) = 3.04 atm
- M is the molar concentration of dissolved species (mol/L).
- R is the ideal gas constant = 0.08206 L-atm/mol- K
- T is the temperature (Kelvin) = 295 K
You can solve for M:
<u>3. Number of moles</u>
You can calculate the number of moles of the dissolved species using the formula:
<u>3. Equation to find moles of each compound</u>
Number of moles of each compound:
i) Vitamin C
Let x be the mass in grams of vitamin C in the 1.124g sample. Then, 1.124g - x is the mass of sucralose.
- Number of moles = mass in grams / molar mass
- Number of moles = x / 176.13 g/mol = x / 176.13
ii) Sucralose
- Number of moles = (1.124g - x) / 397.64 g/mol = (1.124 - x / 397.64)
iii) Total moles equation:
Then,
And the mass percent of vitamin C and sucralose are:
