Autism is a disability that results from a disorder in the central nervous system. It has been speculated that the increasing number of cases of autism in recent years is due to the increase in the number of vaccinations given to young children. What might be another possible explanation for this phenomenon?

Answers

Answer:

Explanation:

As described in the question, autism is a disability that arises from a disorder in the central nervous system which is actually characterized by abnormality in the brain structure and then function. Autism is known for symptoms such as challenges with communication and interaction and some obsessive behaviors. While there is generally no known scientific cause for autism but trends have suggested that vaccination in young children causes autism.

However, genes could also be involved in this phenomenon because there have been reports of unusual genetic sequence in children that have autism. Hence, there is a possibility that vaccination actually triggers this genetic sequence which is then expressed as autism in the children.

Please note this isn't a scientific fact and just a possibility as requested in the question.

Answers

Answer:

Ionic compounds conduct electricity when dissolved in water, because the dissociated ions can carry charge through the solution. Molecular compounds don't dissociate into ions and so don't conduct electricity in solution.

A brick delivery truck parks on a roadside scale that measures 4 m by 6 m. If the brick truck weighs 60 000 N, what pressure does the scale put on the spring below?

Answers

Explanation:

Area = Length × Breadth

A = 4 × 6

A = 24m square/ 24m sq.

Force = Pressure × Area

Force = 60,000 N/ 60,000 Newton

Pressure = Force/ Area

P = 60,000/24

P = 2500 Pa

A piece of aluminum has a mass of 12.0 g. When it is placed into a graduated

of aluminum?
0 2.66667g/ml
O 2.67 g/mL
O 2.667g/mL
O 2.7 g/mL

Answers

Answer:

The answer is 2.7 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 12 g

volume = final volume of water - initial volume of water

volume = 18.5 - 14 = 4.5 mL

So we have

[tex]density = \frac{12}{4.5} \\ = 2.66666666...[/tex]

We have the final answer as

2.70 g/mL

A hiker tries to prepare a hard-boiled egg on the high slopes of Mount Everest. The base camp is located 5,300 meters above sea level. The hiker observes that the water begins to boil at 82⁰C, much lower than the 100⁰C needed to cook the raw egg. He hopes that just leaving the egg in the boiling water longer will let the egg cook. Will he have hard-boiled eggs for breakfast?

Answers

Answer:

He will not have hard-boiled eggs for breakfast

Explanation:

The given parameters are;

The elevation at which the base camp of the hiker is located = 5,300 meters

The boiling point of water at the elevation of the base camp = 82°C

The temperature required to cook the raw egg = 100°C

Therefore, we have;

The temperature of the boiling water at the given elevation of the base camp 82°C < The temperature required to cook the raw egg 100°C

Therefore, the eggs will not be hard boiled.

The hiker won't have hard-boiled eggs for breakfast as a result of the

boiling point of water being less than 100⁰C.

The boiling point decreases with an increase in altitude. The hiker was at

5,300 meters above sea level which made the boiling point of water to be

decreased to 82⁰C.

Since the water isn't able to achieve the boiling point of 100⁰C, then the raw

egg won't be hard boiled for breakfast.

Chemical  formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols  of elements. It also makes use of brackets and subscripts.

Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form  is called empirical formula.

It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.They are used to describe the chemical reactions.

Chelsea adds a 65% acid solution to 25 milliliters of a solution that is 30% acid. How much of the 65%
acid solution should be added to create a solution that is 40% acid?

Answers

Answer:

10 ml

Explanation:

The concentration of the acid solution Chelsea adds to the 25 milliliters of 30% acid solution = 65%

The concentration of the acid solution Chelsea requires = 40%

The volume, X, of the 65% acid solution required is given as follows;

65% × X + 30% × 25 = 40% × (25 + X)

As fractions, we have;

0.65 × X + 0.3 × 25 = 0.4 × (25 + X)

0.65·X + 7.5 = 10 + 0.4·X

0.65·X  - 0.4·X = 10 - 7.5

0.25·X = 2.5

X = 2.5/0.25 = 10

X = 10 ml

The volume of the 65% acid that should be added to create a solution that is 40% acid = 10 ml.

How many atoms of aluminum (Al) are contained in 3.73 moles of alumni

Answers

Number of atoms : 2.245 x 10²⁴

Further explanation  

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

n= 3.73 moles

If 4.7 moles of oxygen gas are allowed to react with 3.9 moles of iron according to the following equation:
4 Fe + 3 O2 → 2 Fe2O
How many moles of Fe2O3 can be formed?​

Answers

Moles of Fe₂O₃ formed : 1.95

Further explanation

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

[tex]\tt 4Fe+3O_2\rightarrow 2Fe_2O_3[/tex]

We find the limiting reactant from the ratio of the mole and the reaction coefficient

Fe ⇒ 3.9 : 4 = 0.975

O ⇒ 4.7 : 3 = 1.56

Because the ratio of Fe is smaller, then Fe becomes the limiting reactant

Reaction

4Fe + 3O₂ ⇒ 2Fe₂O₃

mol Fe₂O₃ from mol of Fe as limiting reactant

mol ratio Fe₂O₃ : Fe = 2 : 4, then mol Fe₂O₃ :

[tex]\tt =\dfrac{2}{4}\times 3.9=\boxed{\bold{1.95}}[/tex]
