Water (H 2 O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding.

Answer:
Analyzing the wavelength of maximum absorbance
Explanation:
Using spectrophotometry during the course of the reaction can confirm that the reaction took place.
The complex [Cu(NH₃)₄]²⁺ has a characteristic wavelength of maximum absorbance ( ), which can be looked up in literature. This characteristic λmax is <u>different</u> from the characteristic λmax of the reagents, as [Cu(NH₃)₄]²⁺ absorbs red-orange light and thus appears with a deep blue-violet color.
Answer:
P₂ = 592.7 torr
Explanation:
Given data:
Initial Pressure = 215 torr
Initial volume = 51.0 mL
Final pressure = ?
Final volume = 18.5 mL
Solution:
P₁V₁ = P₂V₂
P₁ = Initial Pressure
V₁ = Initial volume
P₂ = Final pressure
V₂ = Final volume
Now we will put the values in formula.
P₁V₁ = P₂V₂
215 torr × 51.0 mL = P₂ × 18.5 mL
10965 mL. torr = P₂ × 18.5 mL
P₂ = 10965 mL. torr /18.5 mL
P₂ = 592.7 torr
Ummmm i think you probly can reaserch it on google
