Answer: b) closer to F because fluorine has a higher electronegativity than hydrogen.

Explanation:

Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms.

electronegativity of flourine = 3.98

electronegativity of hydrogen = 2.1

As electronegativity of flourine is greater than that of electronegativity of hydrogen, the electron pair lie towards flourine , thus creating a partial negative charge on flourine and a partial positive charge on hydrogen.

How do you convert from Fahrenheit to Celsius temperatures
balu736 [363]
Well, 1st, you need to take the Fahrenheit temperature and subtract it from 32, make sure you put it in parentheses. Then, 2nd, you multiply it by it by 5/9. Here's an example of my explanation didn't make since:
T(°C) = (68°F - 32) × 5/9 = 20 °C
And that's how you convert Fahrenheit to Celsius temperatures.

How many moles of gallium chlorate, Ga(ClO3)3, must react in order to produce 674 kJ of energy according to the following reacti
Valentin [98]

Answer:

10.3 mol Ga(ClO₃)₃

Explanation:

Let's consider the following balanced thermochemical equation.

2 Ga(ClO₃)₃(s) ⇒ 2 GaCl₃(s) + 9 O₂(s)  ΔH = - 130.4 kJ

According to the balanced thermochemical equation, 130.4 kJ of heat are released when 2 moles of gallium chlorate react. The number of moles of gallium chlorate that must react to produce 674 kJ of energy is:

674 kJ × 2 mol Ga(ClO₃)₃/130.4 kJ = 10.3 mol Ga(ClO₃)₃

andrew-mc [135]

Answer:

I assume your talking about carbon when you say 12 so it'd be 12 grams if you are

Explanation:

The molar mass of any substance in grams per mole is numerically equal to the mass of that substance expressed in atomic mass units.

Hope this helps you some
