What is the total number of valence electrons in a carbon atom in the ground state
kolbaska11 [484]
Carbon will have 4 valence electrons.  It will have 2 in the p orbital and 2 in the s orbital.  You can see this when you find the noble gas configuration of carbon which is [He]2s²2p² showing that carbon has 4 valence electrons.
I hope this helps.  Let me know if anything is unclear.

At a certain temperature, the ph of a neutral solution is 7.43. what is the value of kw at that temperature? express your answer
Delvig [45]

The formula for Kw is:

Kw= [H]*[OH]

where [H] and [OH] are concentrations 

We are given the pH so we can calculate the [H] concentration from the formula:
pH=-log[H] 
7.43 = -log[H]

[H] = 3.715x10^-8 M

In neutral solution, [H] = [OH], therefore: 

<span>[OH]= 3.715x10^-8 M

Calculating Kw:

Kw = (3.715x10^-8)*( 3.715x10^-8)</span>

<span>Kw = 1.38 x 10^-15 </span>

The weight of the buggy was 40N on Mars. When the buggy landed on Mars it rested on an area of 0.025 m2. Calculate the pressure
elena-s [515]

Answer:

The pressure exerted by the buggy on the surface of Mars is 1600 pascals.

Explanation:

The pressure is determined by the definition of stress, which is the force exerted by the buggy on the martian surface divided by the contact area of the latter:

\sigma = \frac{F}{A}

Where:

\sigma - Stress, measured in pascals.

F - Force, measured in newtons.

A - Area, measured in square meters.

The force is the weight of the buggy (40 N) and A = 0.025\,m^{2}, the stress is now calculated:

\sigma = \frac{40\,N}{0.025\,m^{2}}

\sigma = 1600\,Pa

The pressure exerted by the buggy on the surface of Mars is 1600 pascals.

Gastric acid pH can range from 1 to 4, and most of the acid is HCl.
erma4kov [3.2K]

Given the molarity of the solution is3.03*10^{-2}.

The volume of the solution is 10.9/1000 L

Number of moles of HCl = Molarity * volume of the solution in L

Number of moles of HCl =3.03*10^{-2}*\frac{1000}{10.9}

Number of moles of HCl = 2.7 moles.

Therefore number of moles of HCl in 10.9 ml of the stomach acid is 2.7 moles
