Why do you think the transition metals are 10 columns wide?

2 answers:

The transition metals are 10 columns wide because they can hold no more than 10 electrons. This is why their width correlates with the number of electrons that are included in these metals. Transition metals include most commonly used metals, such as iron, copper, silver, and gold.

50.0 mL of an HNO3 solution were titrated with 36.90 mL of a 0.100 M LiOH solution to reach the equivalence point. What is the m

Xelga [282]

Following reaction takes place between LiOH and HNO3

LiOH + HNO3 → LiNO3 + H2O

Thus, 1 mole of LiOH reacts with 1 mole of HNO3 to form 1 mole of LiNO3.

Now,
Number of millimoles of LiOH consumed = 36.90 X 0.100 = 3.690

∴Number of millimoles of HNO3 present = 3.690

Now, Molarity of HNO3 = $\frac{\text{number of millimoles of HNO3}}{\text{volume of solution (ml)}}$
= $\frac{3.690}{50}$ = 0.0738 M

Thus, molarity of the HNO3 solution is 0.0738 M

How can you tell from the name the types of bonds present in a hydrocarbon?

Darya [45]

Answer:

Alkane

Alkene

Alkyne

Explanation:

Alkane=1 bond (Saturated hydrocarbon)

Alkene= 2 bonds (Unsaturated hydrocarbon)

Alkyne= triple bonds (Unsaturated hydrocarbon)

Formula of Alkane = CnH2n+2

Formula of Alkene = CnH2n

Formula of Alkyne = CnH2n-2

White raven [17]

Molar mass:

Atomic mass O = 16.0 a.m.u

O₃ = 16.0 x 3 => 48.0 g/mol

Therefore:

1 mole O₃ --------------- 48.0 g
0.020 mole O₃ ---------- ??

0.020 x 48.0 / 1 =

0.96 / 1 => 0.96 g

hope this helps!
