Can you send a picture of the work so I can help you out ?
ZnSO₄ + 3NH₃ = [Zn(NH₃)₃]SO₄ threeamminezinc sulfate
Zn²⁺ + 3NH₃ = [Zn(NH₃)₃]²⁺ threeamminezinc cation
Answer:
Molarity = 0.002 M
Explanation:
Given data:
Mass of calcium chloride = 0.321 g
Volume of water = 1.45 L
Molarity of solution = ?
Solution:
Molarity = number of moles / volume in litter.
We will calculate the number of moles of calcium chloride first.
Number of moles = mass/molar mass
Number of moles = 0.321 g/ 110.98 g/mol
Number of moles = 0.003 mol
Molarity:
Molarity = 0.003 mol / 1.45 L
Molarity = 0.002 M
The answer is both are made of cells that contain a nucleus. Since they made up of cells that have a nucleus enclosed within membranes, bees and flowers can be classified under Domain Eukarya. Animals are heterotrophic, have no cell walls and no cloroplasts, while plants are autotrophic, have cell walls with cellulose and have chloroplasts.
[ H₃O⁺] = 10 ^ - pH
[ H₃O⁺ ] = 10 ^ - 7.30
[ H₃O⁺ ] = 5.011 x 10⁻⁸ M
hope this helps!
