The formula to convert from Celsius to Fahrenheit is F = 9/5C + 32 or F = (C*1,8)+32

F = 9/5*39 + 32 = 70,2 + 32 = 102,2° F

Which element has the highest electronegativity and why?
BigorU [14]

Answer:

See below

Explanation:

Hello there!

Electronegativity is the atom's tendency to attract electrons in a chemical bond

There are two trends to electronegativity:

  • Electronegativity increases from bottom to top in a group (Li has a greater electronegativity than Fr, for example)
  • Electronegativity increases from left to right across a period (the further right the group, the greater the electronegativity)

Looking at a period table, Sb, Sn, Te, and I are all in the same period, so we'll need to decide which element has the highest electronegativity based on the group.

  • Sn belongs to group 4A (group 14)
  • Sb belongs to group 5A (group 15)
  • Te belongs to group 6A (group 16)
  • I belongs to group 7A  (group 17)

As I belongs to group 7A, the group that is the farthest right based off of the options given, I has the highest electronegativity

Hope this helps!

Combustion reactions are a notable source of carbon dioxide in the environment. Using the following balanced equation, how many
iris [78.8K]

Answer:

Explanation:

Number of moles of propane:

=Mass in grams ÷ Relative molecular Mass

= 100/((12*3) + (1*8))

= 100 ÷ 44

= 2.2727

Mole ratio propane:carbon (IV) oxide = 1:3(from the equation)

Number of moles of CO2 = 3*2.2727 = 6.8181

Mass in grams = Relative molecular Mass * Number of moles

= 44 * 6.8181

= 299.9964 grams
