Chemistry
1 answer:
Kamila [148]3 years ago

Answer:

Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

The volume of a gas is decreased from 100 liters at 173.0°C to 50 liters at a constant pressure. After the decrease in volume, w
Minchanka [31]

Answer:

223.08 K

Explanation:

First we <u>convert 173.0 °C to K</u>:

  • 173.0 °C + 273.16 = 446.16 K

With the absolute temperature we can use <em>Charles' law</em> to solve this problem:

  • T₁V₂=T₂V₁

Where in this case:

  • T₁ = 446.16 K
  • V₂ = 50 L
  • T₂ = ?
  • V₁ = 100 L

We <u>input the data</u>:

  • 446.16 K * 50 L = T₂ * 100 L

And <u>solve for T₂</u>:

  • T₂ = 223.08 K

Calculate the number of atoms in 4.8 dm^3 of neon gas at rtp
WINSTONCH [101]

No of atoms in 4.8 dm³ of neon gas is determined in the following way.

Explanation:

We have given

Neon Gas=4.8dm³

At STP

1 mole of an ideal gas occupies 22.4 L(dm³) of volume.

which means that  number of molecules occupy 22.4 L of volume.

So

4.8 dm³x 1 mole/22.4 dm³ = 0.214 moles Neon

0.214 moles x 6.02x10²³ atoms/mole = 1.29x10²³ atoms of Neon

No of Atoms in 4.8dm3 neon gas =1.29x10²³ atoms of Neon

Pls help! 2CO + O2 → 2CO2
jok3333 [9.3K]

The bond energy of each carbon-oxygen bond in carbon dioxide is d. 736 kJ

Since the chemical reaction is 2CO + O₂ → 2CO₂ and the total bond energy of the products carbon dioxide CO₂ is 1,472 kJ.

Since from the chemical reaction, we have 2 moles of CO₂ which gives 1,472 kJ and there are two carbon-oxygen, C-O bonds in CO₂, then

2 × C-O bond = 1,472 kJ

1 C-O bond = 1.472 kJ/2

C-O bond = 736 kJ

So, the bond energy of each carbon-oxygen bond in carbon dioxide is d. 736 kJ
