Using these Elements. Here would be the 4 ionic compounds.
CaF2
VF5
CaS
V2S5
B. alcohol
Hydroxyl group is an -OH branch
so,
R - OH is alcohol
I found a similar problem to this as shown in the attached picture to helpme answer the problem. We use the M₁V₁ = M₂V₂ formula, wherein M₁ is the concentration of the original CuSO₄ solution, V₁ is the volume of CuSO₄ in the cuvette, M₂ is the concentration of Cu²⁺ in the cuvette, and V₂ is the total volume in the cuvette.
For cuvette 1:
M₁V₁ = M₂V₂
(0.06)(4 mL) = (M₂)(6+4 mL)
M₂ =
<em>0.024 M Cu²⁺</em>For cuvette 2:
M₁V₁ = M₂V₂
(0.06)(7 mL) = (M₂)(7+3 mL)
M₂ =
<em>0.042 M Cu²⁺</em>
Climate can determine a lot of things, but it especially determines what kind of plants and animals can live in an area. For example, polar bears need a cold climate. They would be terribly hot and would die quickly in the desert. When climates start to change, animals and plants become endangered.
Winds are generally in the same direction in certain places over the oceans. They have names like the North East Trade winds and Westerlies. These winds are important in climates and were also important to ancient sailing ships which needed the power of the wind to travel.

Answer:
All matter consists of indivisible particles called atoms. Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms. Hope that helps : )
