How many sigma and pi bonds are there in phenol?

Answers

Answer 1
Answer: In the most simple phenol, 
sigma bond = 7
pi bond = 3

Higher classes of phenol may have more number of bonds. so, don't confuse from that!

Hope this helps!

Mercury is often used as an expansion medium in a thermometer. The Mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary as the temperature rises. Suppose a Mercury thermometer contains 3.550 g of mercury and has a capillary that is 0.190 mm in diameter. How far does the Mercury rise in the capillary when the temperature changes from 0.0 degrees Celsius to 25.0 degrees Celsius? The density of Mercury at these temperatures is 13.596 g/cm^3 and 13.534 g/cm^3, respectively.

The light intensity of a source is 100 candelas. The illuminance on a surface is 4 lux. How far is the surface from the source?

Answers

The answer is 5 meters.

The illuminance on a surface (E) is equal to the light intensity (I) divided by the square distance from the light source (d):
E = I ÷ d² [=] candela/ square meters = lux.
The unit of the illuminance is lux.

So, it is given:
E = 4 lux
I = 100 candelas
d = ?

If:
E = I ÷ d²
Then
d² = I ÷ E
⇒ d² = 100 ÷ 4
⇒ d² = 25

If we put both sides of the equation under the square root, then:
d² = 25
⇒ d = 5 meters.

Therefore, the surface is 5 meters far from the light source.

For the following reaction: Fe2O3 + 3CO --> 2Fe + 3CO2 how many grams of Fe2O3 is needed to produce 111 g of Fe?

Answers

You need 158.70 grams of Fe2O3 to produce 111 grams of Fe. This is calculated by using the molar masses and stoichiometric relationship of the two compounds.

Solution:

MM Fe = 55.845 g/mol
MM Fe2O3 = 159.69 g/mol
Fe: Fe2O3 = 2 mol:1 mol

11 g FE (1 mol Fe/55.845 g Fe) (1 mol Fe2O3/2 mol Fe) (159.69 g Fe2O3 / 1 mole Fe2O3) = 158.70 grams Fe2O3

What is a solution for deforestation



(full sentences please)

Answers

The best solution to deforestation is to curb the felling of trees by enforcing a series of rules and laws to govern it. Deforestation in the current scenario may have reduced; however, it would be too early to assume. The money-churner nature of forest resources can be tempting enough for deforestation to continue.

The material you should use in the windshield washer container is? usually a special windshield washing solution

Answers

The material you should use in the windshield washer container is a special windshield washing solution.

Using the wrong material in the windshield washer container can cause damage to the windshield and the washer system itself. A special windshield washing solution is specifically designed to clean the windshield effectively and safely, without leaving streaks or residue.

There are several types of special windshield washing solutions available in the market, each with its own set of benefits and features. Some of the most common types include:

1. Deionized water: This type of solution is distilled and purified to remove impurities and minerals that can leave streaks on the windshield. Deionized water is gentle on the windshield and the washer system, and it is effective in removing dirt and grime.

2. Isopropyl alcohol: This type of solution is a mixture of isopropyl alcohol and water. It is effective in removing dirt and grime, and it also helps to dry the windshield quickly. However, it can be too harsh on some types of windshields, so it is important to use it with caution.

3. Glycerin-based solution: This type of solution is made with glycerin, which is a natural humectant that helps to prevent the windshield from drying out. It is also effective in removing dirt and grime, and it leaves the windshield streak-free.

When choosing a special windshield washing solution, it is important to consider the type of windshield you have, as well as the climate and weather conditions in your area. For example, if you live in an area with high humidity, a glycerin-based solution may be the best choice, as it helps to prevent the windshield from fogging up.

It is also important to note that some special windshield washing solutions may not be compatible with certain types of windshields, such as those made of polycarbonate or acrylic. It is always a good idea to consult the manufacturer's instructions before using any solution in your windshield washer container.

In summary, the material you should use in the windshield washer container is a special windshield washing solution that is specifically designed for the type of windshield you have and the climate and weather conditions in your area. It is important to choose a solution that is gentle on the windshield and the washer system, and that is effective in removing dirt and grime.
