How do electronegativity values help us determine the type of bond created?

Ann [662]

Answer: The difference between the electronegativity or (∆EN) of two different atoms indicates the type of bond created.

Explanation: For ionic bond compounds the difference between their electronegativity is 1.7 or greater. Covalent bond compounds have a difference of 0.4 but not greater than 1.7 on their electronegativity.

Answer:

The best way to admit you like him would be to act normal. Don't be someone your not and just admit to him that you like him. Yolu could do it while ya'll are talking but don't just suddenly spring it on him. If he is a true friend, your friendship will remain even if he doesn't like you back.

A slice of pizza has 500 kcal. If we could burn the pizza and use all the heat to warm a 50-L container of cold water, what woul

gayaneshka [121]

Answer:

10°C

Explanation:

Heat gain by water = Heat lost by the slice of pizza

Thus,

$m_{water}\times C_{water}\times \Delta T=Q$

<u>For water: </u>

Volume = 50.0 L

Density of water= 1 kg/L

So, mass of the water:

$Mass\ of\ water=Density \times {Volume\ of\ water}$

$Mass\ of\ water=1 kg/L \times {50.0\ L}$

Mass of water = 50 kg

Specific heat of water = 1 kcal/kg°C

ΔT = ?

For slice of pizza:

Q = 500 kcal

So,

$50\times 1\times \Delta T=500$

ΔT = 10°C

Increase in temperature = 10°C
