The factor in determining the average atomic mass of an element is: 
B or 2 relative abundance of each isotope because the by looking at how many protons , electrons and neutrons the most isotope is of the element has relative abundance.

Answer: The correct option is 2.

Explanation: Average atomic mass of an element is the summation of the relative abundance of each isotope multiplied by its atomic mass.

Mathematically,

\text{Average Atomic Mass}=\sum_{i=1}^n(\text{Relative Abundance})_i\times (\text{Mass number})_i

From the above relation, it is visible that the average atomic number of an element is dependent on relative abundance of each isotope.

Cocaine selectively blocks na+ (sodium) channels, which is the mechanism that leads to
anzhelika [568]
Cocaine selectively blocks sodium channels which is the mechanism that leads to local anesthetic effects. 
Voltage gated sodium channels play very important roles in the body as they are responsible for action initiation and propagation in excitable cells, such as nerves, muscles and neuroendocrine cells. Like other sodium ion channels blockers such as lidocaine, Cocaine selectively blocks sodium ion channels which denies entry of sodium ions in the cell, thus leading to local anesthetic effects.

Tell how many moles of each element are in the following amounts of each compound
qwelly [4]
Take note of the subscript written for each element in the compound. To find the total number of moles, make sure to multiply the subscript with the number of moles of compound. The answer for each is written below:

a. 3*1 = 3 moles Nitrogen; 3*3 = 9 moles Hydrogen
b. 0.25*2 = 0.5 moles Hydrogen; 0.25*1 = 0.25 moles Oxygen
c. 5*2 = 10 moles Hydrogen; 5*1 =5 moles Sulfur; 5*4 = 20 moles Oxygen
d. 0.75*1 = 0.75 moles Calcium; 0.75*1*2 = 1.5 moles Nitrogen; 0.75*3*2 = 4.5 moles Oxygen

If you were to mass the reactants before a reaction and then mass the products after the reaction what would you expect to find
TiliK225 [7]

Answer:

No change...

Explanation:

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
