Computers don’t have the ability to see as much as we do and in Construction sites this can be very dangerous if your driverless car has not been properly updated in an area where there’s a lot of construction you can we put into harms way. The lanes may have changed and they will not have the data to be able to recognize this in time and you could get into a serious car crash.

Enough of a monoprotic acid is dissolved in water to produce a 0.0121 M solution. The pH of the resulting solution is 6.49. Calc

Hitman42 [59]

Calculate the H positive from the pH equation: pH equals -log (H positive). This would be 10 to the -6.49. Let's call the acid HA. To calculate Ka in this equation, Ka equals H positive times A- over HA. HA is going to be the 0 0121. So, Ka=(10^-6.49)^2/0.0121. This equals 1.05*10^-13/0.0121. Ka then equals 8.65*10^-12.

What quantity is the same among atoms of the same element?

Vedmedyk [2.9K]

Answer:

Neutrons or Neutral atoms

Explanation:

Neutral atoms of each element contain an equal number of protons and electrons. The number of protons determines an element's atomic number and is used to distinguish one element from another.

Which of the following has the greatest electronegativity difference between the bonded atoms? a. A strong acid made of hydrogen

NARA [144]

Answer: Option (d) is the correct answer.

Explanation:

Electronegativity value of hydrogen is 2.2.

Electronegativity value of chlorine is 3.16.

Electronegativity value of carbon is 2.55.

Electronegativity value of oxygen is 3.44.

Electronegativity value of nitrogen is 3.04.

Electronegativity value of sodium is 0.93.

Electronegativity value of iodine is 2.66.

Therefore, calculate the electronegativity difference between the bonded atoms as follows.

Electronegativity difference of HCl = Electronegativity value of chlorine - electronegativity value of hydrogen

= 3.16 - 2.2

= 0.96

Electronegativity difference of CO = Electronegativity value of oxygen - electronegativity value of carbon

= 3.44 - 2.55

= 0.89

Electronegativity difference of $N_{2}$ = Electronegativity value of nitrogen - electronegativity value of nitrogen

= 3.04 - 3.04

= 0

Electronegativity difference of NaI = Electronegativity value of iodine - electronegativity value of sodium

= 2.66 - 0.93

= 1.73

So, we can see that highest electronegativity difference is 1.73 and it is shown by NaI molecule.

Thus, we can conclude that a group 1 alkali metal bonded to iodide, such as NaI has the greatest electronegativity difference between the bonded atoms.

<h3>Answer:</h3>

4.3 miles

<h3>Explanation:</h3>

We are given;

Distance of 22,704 feet

We are required to determine the number of miles in 22,704 feet

To convert one unit to another we use conversion factors
Therefore, we need to know the suitable conversion factor.
That is, 1 mile/5,280 feet
Thus, to determine the number of miles we multiply the number of feet with the conversion factor.

That is;

= 22,704 feet × 1 mile/5,280 feet

= 4.3 miles

Therefore, there are 4.3 miles in 22,704 feet
