The atomic mass of magnesium is the weighted average of the atomic masses of
Debora [2.8K]

Answer:

2. All the naturally occurring isotopes of Mg.

Explanation:

You want to know the atomic mass of the magnesium you use in the lab. That’s “natural” magnesium. So, you must use the weighted average of all the naturally occurring isotopes in natural Mg.

1. and 3. are <em>wrong</em>. You won’t get the correct mass for natural Mg if you use only the artificial isotopes for your calculation.

4. is <em>wrong</em>. You must use all the naturally occurring isotopes. The two most abundant isotopes of Mg account for only 90 % of the atoms. If you ignore the other 10 %, your calculation will be wrong.

Where is energy stored in a carbon-based molecule like glucose? responses the space between atoms the space between atoms the hy
Alik [6]

Food is made up of organic (carbon-containing) molecules that contain chemical bonds between their atoms that act as energy storage units. In addition to using the energy in food to fuel life processes, organisms construct larger organic molecules, such as proteins, DNA, and fats (lipids), using the atoms from food molecules.

What is glucose ?

The primary form of sugar in the blood, glucose serves as the body's cells' main source of energy. Glucose can be produced by the body from other chemicals or it can be obtained from the meals we eat. The bloodstream carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.

What relationship is described by the formula below? (mass of the element/mass of the compound) x 100
Fiesta28 [93]
Introduction
empirical formula
A table of values shows a list of the values for an independent variable, x, matched with the value of the dependent variable, y. In many cases, an equation can be used to relate the two values. If you know the equation, you can easily generate a table of values.


If you are given the table of values, you must determine how the two values are related and then write an equation that shows the relationship.

xy-2-1-100112When looking at the relationship between the y-values and the x-values, it's easy to see that each y-value is 1 more than the x-value. Therefore, the equation that describes this relationship is y = x + 1.

 

Develop a Rule When Given a Table of Values

Writing an Equation for a Table of Values

Look at the table below. There does not appear to be a constant rate of change.



In this example, we look at the ratio of the change in the pattern of y-values and x-values.









Even though there did not appear to be a constant rate of change, there is actually a constant rate of change of 2.

We're almost ready to write our equation.

We now know the value for m (the slope) in the equation y = mx + b is 2. Since m is 2, we know that each x-value is being multiplied by 2.

What else is happening to the x-value to get the corresponding y-value?

xProcessy-32(-3) + 3-3-12(-1) + 3132(3) + 3962(6) + 31572(7) + 317

We also need to add 3 to the product in order to get the corresponding y-value.

The equation that represents this table of data is y = 2x + 3.
