What does it mean when a covalent bond is polar? How can you tell if a bond is polar or nonpolar?

Answer:

If the covalent is polar its means that pair of electrons are unequally shared between both atoms.

Through electronegativity difference.

Explanation:

Covalent bond:

It is the bond which is formed by the sharing of electrons between the atoms.

It is weaker than the ionic bond. The both bonded atoms do not completely transfer the electrons but can only shares.

For example:

The bond between the both chlorine atoms Cl₂ is coavlent. Cl:Cl

The bond between the H₂ atoms is covalent. H:H

The covalent bond can be polar or non polar. When it is formed between the atoms of two different elements then electronegativity difference is created. The atom atoms with high electronegativity values attract more strongly the shared pair of electron towards it self and become partial negative while the other became partial positive. Thus bond become polar.

But this is only in case when the electronegativity difference between both atoms is 0.4 are greater. If the difference is less than 0.4 than bond is non polar.

For example:

HCl, H₂O

The polar covalent bond is present in HCl and water because of greater electronegativity difference between hydrogen and chlorine , oxygen and hydrogen.

A toxicity of folate can disguise a deficiency of which nutrient, resulting in nerve damage?
Ket [755]

Large dose of folate increase the symptom of vitamin B12 deficiency . the vitamin B12 deficiency can lead to permanent damage of the spinal cord nerves and brain.

It can cause severe birth defects which is called neural tube defects. this defects include spinal, pifida . folate deficiency can also increase your chance of placental abrupt ion is a condition in which placental separate from uterus.

High dose of folate typically be remedied by taking supplement of both folic acid and vitamin B12. vitamin B12 works closely with vitamin B9 also called folic and folate acid which is help to make red blood cells and iron work better in our body.

Claytonia virginica is a woodland spring herb with flowers that vary from white to pale pink to bright pink. Slugs prefer to eat
Lemur [1.5K]

Answer:

C) The percentage of pink flowers should increase over time.

Explanation:

According to the given information, the plants with pink flowers are able to reproduce more but are also have higher rates of herbivores as the slugs preferably eat the pink-flowered plants.

If slugs are removed from the system, the plants with pink flowers would have an absolute reproductive advantage over the plants with white flowers. This would increase the frequency of plants with pink flowers as they exhibit reproductive success over the plants with white flowers.

Julio wants to study the effect of water temperature on hatching of fish eggs in a lake which these experiment designs would be
almond37 [142]

Complete Question: Julio wants to study the effect of water temperature on the hatching of fish eggs in a lake. which of these experimental designs would be most practical for julio?

a. he should put fish eggs in aquariums of lake water kept at different temperatures and observe.

b. he should build a computer model of fish eggs in a lake that has many different water temperature settings.

c. he should use cameras to observe fish hatching in the lake and temperature probes to monitor water temperature.

d. he should take water samples from lakes of different temperatures and observe for eggs and newly hatched fish.

Answer: is <em>a). he should put fish eggs in aquariums of lake water kept at different temperatures and observe. </em>

Explanation:

By viewing all four options the most accurate and near to possible is <em>option A. </em>Other three techniques are not doable and have higher chances of inaccuracy. The results fetch from other techniques will contain various error which results in wrong findings. Instead of studying and controlling whole lake water temperature, a sample of water lake should be taken and adjusted it's temperature accordingly under observation in a controlled and monitored environment. By doing so, the eggs can be monitored and observed under an adjusted temperature with full accuracy. Hence option A is more suitable and more realistic approach in finding the desired results.
