Vaccanation against the flu should not be required

1 answer:

4 0

Vaccination against the flu should not be required because:
- There have been recalls on vaccinations due to problems which will harm you more than the thing they are trying to prevent
- They are pure estimate since there are hundreds of forms of the flu, the percentage rate for success goes from about 50-80%, there have been years where they had 20% rates (aka nothing was prevented)
- Antibiotic resistance is growing and we are running out of vaccinations that work, lowering the amount of users would let the effects of a certain vaccination last longer

Write a scientific explanation that compares the electrical forces of ethanol, hexane, and water.

olchik [2.2K]

Answer:

"Water and ethyl alcohol will both have dipole-dipole interactions.

Technically they will both have Hydrogen bonding, which is a type of dipole-dipole. This is due to the high electronegativity values of oxygen atoms compared to the carbon and hydrogen atoms the oxygens bond to. This causes regions of both of these molecules that have partial negative charges and other regions wind up with partial positive charges.

Hexane will not have any dipole-dipole interactions because it is a non-polar molecule. The intermolecular forces between hexane molecules will be dispersion forces."

A baby weighs 7 pounds, 4 ounces at birth and 7 pounds, I ounce at discharge. What percent of weight did the baby lose

Aloiza [94]

Answer:

2.6%

Explanation:

As, 1 ounce (oz) = 0.0625 pounds (lb)

Therefore, weight of baby at discharge = 7 lb,1 oz = 7+0.0625 lb = 7.0625 lb

Since, 1 oz = 0.0625 lb

⇒ 4 oz = 4×0.0625 = 0.25 lb

Therefore, weight of baby at birth = 7 lb,4 oz = 7+0.25 lb = 7.25 lb

The amount of weight lost is equal to the difference of weight of the baby at birth and discharge.

Therefore, weight lost = 7.25 lb - 7.0625 lb = 0.1875 lb

Now, the percentage of weight lost by the baby is given by the amount of weight lost divided by the weight of the baby at birth.

Therefore, the percentage of weight lost = weight lost ÷ weight at birth = 0.1875 lb ÷ 7.25 lb × 100 = 2.6%
