REALLY NEED HELP!!! Chemistry
kicyunya [14]

Answer:

C.) 2

Explanation:

The pH equation is:

pH = -log[H⁺]

In this equation, [H⁺] is the molarity of the acid. In this case, the acid is HCl. Molarity can be found using the equation:

Molarity (M) = moles / volume (L)

Since you were given moles and volume, you can find the molarity of HCl.

Molarity = moles / volume

Molarity = 0.01 moles / 1.00 L

Molarity = 0.01 M

Now, you can plug the molarity of the acid into the pH equation.

pH = -log[H⁺]

pH = -log[0.01]

pH = 2

How much heat is required to change the temperature of 100 grams of water from 25 to 55oc?
marysya [2.9K]
Hthe heat required  to change the temperfature  of 100 grams of water  from 25 to 55 c is calculated as below

Q(heat) = M(mass) x C(specific heat capacity) x delta T(change  in temperature)

M= 100 grams
C= 4.18 j/g/c
delta T= 55-25 =30c

Q=100 g x4.814 j/g/c x  30c = 12552  joules

How does silicon dioxide become a covalent bond. (explain)
tatuchka [14]
Silicon dioxide is SiO2.  Silicon has 4 valence electrons, while each oxygen has 6 valence electrons.  This can be shown as 
     **             *                   *
**  O *       *  Si   *        *   O  **
      *               *                 **
At points where there is one valence electron, represented by a lone *, the electrons will be 'shared' between the atoms.  This will make silicon dioxide appear as
   **           *--------------- *
**  O *--*  Si   * ------ *   O  **
      *------- *                 **
, as the lines with no arrows indicate that each electron moves between the atoms, and does not stay with one forever.
