The digestive system is a group of organs working together to convert food into energy and basic nutrients that are transported

throughout the body. Food passes through a long tube inside the body known as the alimentary canal, made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Once food is chewed, the bolus is moved into the stomach for further digestion. Examine the Interconnections chart and select the body system that is responsible for moving the food from the start to the finish of the digestive system.
A) nervous system
B) muscular system
C) integumentary system

PLEASE HELP!! What is the concentration [H3O+] of a solution with a pH of 13.2? Is the solution acidic, basic, or neutral?
Ilya [14]

The  concentration of [H3O+] will be 6.3 x 10^{-14} M

<h3>pH</h3>

Mathematically, pH = -log [H+] or -log [H3O+]

With a pH of 13.2:

      -log [H3O+] = 13.2

                     log [H3O+] = -13.2

                         [H3O+] = 6.3 x 10^{-14} M

The two naturally occurring isotopes of antimony, 121Sb (57.21 percent) and 123Sb (42.79 percent), have masses of 120.904 and 12
Alex

Answer:

The correct answer is option c.

Explanation:

Formula used to determine an average atomic mass :

\text{Average atomic mass }=\sum_{i=1}^n\text{(Atomic mass of an isotopes)}_i\times \text{(Fractional abundance})_i

Mass of isotope Sb-121 = 120.904 amu

Fractional abundance of Sb-121 = 57.21% = 0.5721

Mass of isotope Sb-123 = 122.904 amu

Fractional abundance of Sb-123 = 42.79% = 0.4279

Average atomic mass of Sb:

120.904 amu\times 0.5721+ 122.904 amu\times 0.4279=121.7598 amu \approx 121.76 amu

A compound with chemical formula na2cx3 has formula mass 106 amu .. what is the atomic mass of element x
maria [59]

The element "X" is "O" (oxygen).

<h3>Calculation:</h3>

Given,

Chemical formula = Na₂CX₃

Formula mass = 106 amu

Molar mass of Na = 23 amu

Molar mass of C = 12 amu

To find,

Element X =?

We will equate the equation as follows,

2(23) + 12 + 3(y) = 106

46 + 12 + 3y =106

58 + 3y = 106

3y = 106 - 58

3y = 48

y = 48/3

y = 16

We know that Oxygen has molecular mass of 16. Therefore the element "X" is "O".

Why does nuclear charge increase as you go left to right across a period
MariettaO [177]

 The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.
