Answer:

C=O

Explanation:

We are given that

H-H

C-Cl

C=O

N-N

We know that single bonds are weaker than the double bonds. It can says that the double bonds are stronger than the single bonds.The single bond is formed between two electrons and double bonds are formed between four electrons.

When double bonds are formed between two atoms then one is sigma bond and other is pi bond .Sigma bonds are formed by hybridization between s- s orbital and pi bonds are formed between un-hybridized p- orbitals.

Therefore, Double bonds are stronger than the single bond.Hence, C=O is strongest bond.

Answer: In C=O the bond is strongest bond.

Double bonds are stronger than single bonds. So C=O.

An irregular chunk of iron has a density of 7.87 g/cm3. A 14.5 gram chunk is added to a graduated cylinder. If the final volume

bulgar [2K]

Answer:

37.96 mL

Explanation:

From the question given above, the following data were obtained:

Density (D) of iron = 7.87 g/cm³

Mass (m) of iron = 14.5 g

Volume of Cylinder + Iron = 39.8 mL

Volume of Cylinder =?

Next, we shall determine the volume of the chunk of iron. This can be obtained as follow:

Density (D) of iron = 7.87 g/cm³

Mass (m) of iron = 14.5 g

Volume (V) of iron =?

D = m/V

7.87 = 14.5 /V

Cross multiply

7.87 × V = 14.5

Divide both side by 7.87

V = 14.5 / 7.87

V = 1.84 cm³

Recall:

1 cm³ = 1 mL

Therefore,

1.84 cm³ = 1.84 mL

Therefore, the volume of the chunk of iron is 1.84 mL.

Finally, we shall determine the starting volume of the cylinder as follow:

Volume of Cylinder + Iron = 39.8 mL

Volume of Iron = 1.84 mL.

Volume of Cylinder =?

Volume of Cylinder = (Volume of Cylinder + Iron) – Volume of Iron

Volume of Cylinder = 39.8 – 1.84

Volume of Cylinder = 37.96 mL

Therefore the starting volume of cylinder is 37.96 mL

Initially, a particular sample has a total mass of 200 grams and contains 128 x 1010 radioactive nuclei. These radioactive nucle

lubasha [3.4K]

Explanation:

Formula to calculate how many particles are left is as follows.

N = $N_{0} (\frac{1}{2})^{l}$

where, $N_{0}$ = number of initial particles

l = number of half lives

As it is given that number of initial particles is $128 \times 10^{10}$ and number of half-lives is 3.

Hence, putting the given values into the above equation as follows.

N = $N_{0} (\frac{1}{2})^{l}$

= $128 \times 10^{10}(\frac{1}{2})^{3}$

= $16 \times 10^{10}$

or, $1.6 \times 10^{11}$

Thus, we can conclude that $1.6 \times 10^{11}$ particles of radioactive nuclei remain in the given sample.

In five hours we've gone through 5 half lives so the answer is:

particles

Zns (zinc sulfide) (Zn = 65.38; S = 32.06] *

irakobra [83]

The question is incomplete, the complete question is;

Zinc and sulfur react to form zinc sulfide by the equation shown below. How many grams of ZnS can be formed when 12.0 g of Zn reacts with 6.50 g of S? (Atomic mass: Zn = 65.38, S = 32.06).

Answer:

17.5 g of ZNS

Explanation:

The equation of the reaction is;

Zn(s) + S(s) ------->ZnS(s)

Number of moles of Zn = 12.0/65.38 = 0.18 moles

Number of moles of S = 6.50/32.06 = 0.20 moles

Hence Zn is the limiting reactant

If 1 mole of Zn yields 1 mole of ZnS

Then 0.18 moles of Zn also yields 0.18 moles of ZnS

Mass of ZnS produced = 0.18 moles * 97.44 g/mol = 17.5 g of ZNS
