A small amount of acid is added to a buffer solution, the ph of the solution will

A. increase

B. decrease  

C. stay about the same

D. become neutral


correct option is <u>option C </u>


Buffer is a solution which can resist the change in pH with small addition of acid or base.

Hence a small amount of acid when added to a buffer solution will not change its pH,or its <u>pH remains the same.</u>

Which of the following is a balanced equation?<br><br>Select one:<br>a. A<br>b. B<br>c. C<br>d. D​
Phantasy [73]

Answer:

B

Explanation:

Balanced equations have the same number of elements on both sides. If the number of elements are equal to each other for every element in the equation on both sides, then the equation is balanced.

Important concept : The big number before an element or compound represents how many molecules of that compound or element there are in a reaction. To find the number of atoms of each element you multiply the coefficient by the subscript ( small number ) which represents the number of atoms of that element in each molecule. Ex. 3H2O. There is a coefficient of 3 meaning that there are 3 molecules of H2O. There is a subscript after H meaning there are 2 atoms of hydrogen in each molecule. To find the total number of atoms we multiply the subscript of hydrogen by the coefficient of the whole molecule. 3 * 2 = 6 , so there are a total of 6 atoms of hydrogen in 3H2O

A) Cu + 2AgNO3 ==> CuNO3 + 2Ag

                    1   Cu  1

                    2   Ag  2

                     2   N  1

                     3  O   3

The amount of nitrogen atoms is different on both sides of the equation therefore this is not a balanced equation

B) CCl4 + O2 ==> CO2 + 2Cl2

                     1  C  1

                     4  Cl  4

                     2  O  2

The number of atoms of each element is the same on both sides of the equation therefore this is the balanced equation, however lets check the other answer choices just in case.

C)  2K + H2SO4 ==> K2SO4 + 2H2

                        2  K   2

                        1   H   4

                        1   S    1

                        4  O   4

The number of Hydrogen atoms are different on each side of the equation therefore this is not a balanced equation.

D) 2Al2O3 ==> 2Al + 3O2

              4  Al  2

              6  O  6
There are a different amount of aluminum atoms on both sides of the equation therefore this is not a balanced equation.

What is a hot spot? ( Must be in your own words) Pleaseeee Hurryy
Ilia_Sergeevich [38]

Answer:

A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.

Hope this is what you mean be hot spot!

I hope this helps you!  

Have a great day

Which of the following shows 3x + 15 + 6x – 7 + y in simplest terms?
prisoha [69]

Answer:

9x+y+8

Explanation:

We know this because you add 3x and 6x to get 9x

then we only have one y so put y by itself then subtract 15 and y which gets us 8
