Identify the electronegative element in each of the molecules:
faust18 [17]
Electronegativity means how strongly an atom can attract electrons. The more positive charge an atom has, the better it attracts the negatively charged electrons. However, distance is a factor too, so if the nucleus (where the protons are) starts becoming too large, the strength of the positive charge isn't as large as it would otherwise be.

Basically this means that fluorine is the most electronegative element since it has the most positive charge for its relative size. Elements closer to fluorine have higher electronegativities than elements further from it on the periodic table.

so in other words F is most electro, bc it attracts more electrons to its atom making other atoms Positive

The quantity (current times voltage ) is
maksim [4K]

Answer:

Electrical power

Explanation:

An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.

Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, etc.

The electrical power of an electric circuit can be defined as a measure of the rate at which energy is either produced or absorbed in the circuit.

<em>Mathematically, electrical power is given by the formula;</em>

Electrical \; power = current * voltage

This ultimately implies that, the quantity (current times voltage ) is electrical power and it is measured (S.I units) in Watt (W).

The air pressure for a certain tire is 113 KPa. What is the pressure I’m atmosphere
Fynjy0 [20]

Answer: 1.11 atm

Explanation:

The unit of pressure include kilopascal (kPa), atmospheres (atm), mmHg etc

Now, given that:

Air pressure = 113 KPa

Convert kPa to atm

If 101.325 kPa = 1 atm

113 kPa = Z atm

To get the value of Z, cross multiply

Z atm x 101.325 kPa = 1 atm x 113 kPa

Z = ( 1 atm x 113 kPa) / 101.325 kPa

Z = 1.11 atm

Thus, the pressure is 1.11 atm
