A valid Lewis structure of IF3 cannot be drawn without violating the octet rule.

Answer: IF3 (Iodine Trifluoride)

This is because, I (Iodine) and F (Fluorine) both have odd number of valence electrons (7) which also means that there are too many valence electrons in the valence shell.

Homogeneous series of n-propyl bromide?
goldenfox [79]

The homologous series ( not homogeneous series ) of n-propyl bromide is C3H7Br. It is also known as 1-Bromopropane

n-propyl bromide or 1-bromopropane, is a solvent that is used in cleaning metals, vapor degreasing and also for dry cleaning.

<h3>What is Homologous series?</h3>

Homologous series is a family of organic compound which follows a regular structural pattern and in which successive members differs from one another by a molecular formula of CH2

Below are some of their characteristics:

  • The general formula of all compounds in the series is the same.
  • They have the same functional group.
  • Their physical properties such as melting point, boiling point, density, generally show a gradual change with increase of molecular formula in the series.

A 2.40 kg block of ice is heated with 5820 J of heat. The specific heat of water is 4.18 J•g^-1•C^-1. By how much will it’s temp
MrMuchimi

Answer: The temperature rise is 0.53^0C

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=m\times c\times \Delta T

Q = Heat absorbed by ice = 5280 J

m = mass of ice = 2.40 kg = 2400 g   (1kg=1000g)

c = heat capacity of water = 4.18J/g^0C

Initial temperature  = T_i

Final temperature = T_f  

Change in temperature ,\Delta T=T_f-T_i=?

Putting in the values, we get:

5280J=2400g\times 4.18J/g^0C\times \Delta T

\Delta T=0.53^0C

Thus the temperature rise is 0.53^0C
