oee [108]

Answer:

Ingredient lists and nutritional facts

Explanation:

The packaged food, a consumer purchases has all its details written on the food package which is also verified by a trusted government institution.

  • <u>Ingredient List </u>

The list tells each ingredient in food product by the food's common or usual name in the descending order by the weight.

  • <u>Nutrition Facts Label </u>

FDA requires this label on most of the packaged foods and the beverages. At top of Nutrition Facts label, there is written total number of the servings in container and serving size of food or drink. Serving size on label is based on amount of the food which people eat typically at one time. Rest of nutrition information on label is based usually on one serving of food or beverage.

A sample of an unknown compound was decomposed and found to be composed of 1.36 mol oxygen, 4.10 mol hydrogen, and 2.05 mol carb
AfilCa [17]

We are given the number of moles:

O = 1.36 mol

H = 4.10 mol

C = 2.05 mol

 

To get the empirical formula, first divide everything by the smallest number of moles = 1.36 mol. So that:

O = 1 mol

H = 3 mol

C = 1.5 mol

 

Next step is to multiply everything by a number such that all will be a whole number. In this case, multiply by 2 to get a whole number for C, so that:

O = 2 mol

H = 6 mol

C = 3 mol

 

Therefore the empirical formula of the compound is:

C3H6O2

Perform the following operation and express the answer in scientific notation 8.6500x10^3+6.5500x10^5
Dafna1 [17]

Taking into account the scientific notation, the result of the sum is 6.6365×10⁵.

<h3>Scientific notation</h3>

First, remember that scientific notation is a quick way to represent a number using powers of base ten.

The numbers are written as a product:

a×10ⁿ

where:

  • a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.
  • n is an integer, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.

<h3>Sum in scientific notation</h3>

You want to add two numbers in scientific notation. It should be noted that when the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found.

In this case, the highest exponent is 5.

Then all the values ​​are expressed as a function of the base 10 exponent with the highest exponent. In this case: 8.6500×10³= 0.086500×10⁵

Taking the quantities to the same exponent, all you have to do is add what was previously called the number "a". In this case:

0.086500×10⁵ + 6.5500×10⁵= (0.086500+ 6.5500)×10⁵=  <u><em>6.6365×10⁵</em></u>

Finally, the result of the sum is 6.6365×10⁵.

What kind of statement is," Roller coasters are the best to use of Newton's laws of motions
Advocard [28]

Answer:

An opinion.

Explanation:

In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.

The statement, "Roller coasters are the best use of Newton's laws of motions" is an opinion because it is not based on any evidence, facts or has a proof to back it up.

In English literature, an opinion is considered to be more like a claim.

A claim can be defined as a statement that is used by a writer to prove, substantiate or support an argument. Thus, a claim is an assertive statement expressed by a writer to prove that an argument is true or real.
