Answer: Your answer will D

Explanation: The element which can bond with titanium to form a polar covalent bond is Nitrogen. Polar covalent bond is formed between two elements whose electronegativity difference is in the range of 0.4-1.7.

Answer: Option (A) is the correct answer.

Explanation:

A polar covalent bond is formed due to unequal sharing of electrons between the combining atoms.

Hence, when two metals combine together then there could occur sharing of electrons. But when a metal combines with a non-metal then there will occur transfer of electrons due to which there will be formation of an ionic compound.

So, more is the difference in electronegativity of combining metal atoms more will be unequal sharing of electrons.

Electronegativity of Ti is 1.54, Be is 1.57 and electronegativity of Mn is 1.55. As there is more difference between electronegativity of Ti and Be. So, they will form a polar covalent bond.

Thus, we can conclude that Be is the element which bond with titanium (Ti) to form a polar covalent bond.

A block has a mass of 30g and dimensions of 1.5cm by 4.8cm by 2.3 cm. Will the block float or sink in

zimovet [89]

The block will sink

Explanation:

In general, an object with a higher density than water will sink in it, and one with a lower density will float. Now, to know if the block will float or sink, the first step is to calculate the density of the block, and to do this, the volume and mass of the block are required.

Mass of the block: 30 grames

Volume of the block:

The volume of the block is not provided, but this can be found using the dimensions given.

V (Volume) = s (side) x s x s

V = 1.5 cm x 4.8 cm x 2.3 cm

V = 16.56 $cm^{3}$

Density of the block:

To find the density simply divide the mass into the volume

D (density) = M (Mass) ÷ V (Volume)

D = 30 grams ÷ 16.56 $cm^{3}$

D = 1. 811 grams/ $cm^{3}$

The density of the block is 1. 811 grams/ $cm^{3}$

Additionally, the density of the water is 1 gram/ $cm^{3}$ or 1 gram/mL. According to this, the density of the block is higher than the density of the water, and therefore this is the block sinks.

Which one of the following solutions will have the greatest concentration of hydroxide ions?

jek_recluse [69]

Answer:

e = 0.250 M calcium hydroxide

it will produce 0.5 M [OH⁻].

Explanation:

A = 0.100 M HCl

HCl is an acid it would produce negligible amount of OH⁻.

B = 0.100 M magnesium hydroxide

Mg(OH)₂ + H₂O → Mg²⁺ + 2OH⁻

The ration of Mg(OH)₂ and OH⁻ is 1:2.

[OH⁻] = 2× 0.100 = 0.200 M

C =0.100 M ammonia

NH₃ + H₂O → NH₄OH → NH₄⁺ + OH⁻

The Kb expression will be written as,

Kb = [NH₄⁺] [OH⁻] / [NH₃]

Kb = 1.8 ×10 ⁻⁵

Now we will put the values:

1.8 ×10 ⁻⁵ = [NH₄⁺] [OH⁻] / 0.100

[NH₄⁺] [OH⁻] = x²

1.8 ×10 ⁻⁵ = x² / 0.100

x² = 1.8 ×10 ⁻⁵ × 0.100

x² = 1.8 × 10 ⁻⁶

x = 1.34 × 10 ⁻³

[OH⁻] = 1.34 × 10 ⁻³ M

d = 0.300 M rubidium hydroxide

RbOH + H₂O → Rb⁺ + OH⁻

The ratio of RbOH and OH⁻ is 1:1.

[OH⁻] = 0.300 M

e = 0.250 M calcium hydroxide

Ca(OH)₂ + H₂O → Ca²⁺ + 2OH⁻

The ration of Ca(OH)₂ and OH⁻ is 1:2.

[OH⁻] = 2× 0.250 = 0.5 M
