Answer: Option (D) is the correct answer.

Explanation:

When heat or energy is transferred through the space in the form of waves or through a material medium then it is know as radiation.

For example, when we take Sun bath then our body gets warm due to solar radiation.

For transfer of heat through radiation it is not necessary that the objects have to in contact with each other.

Thus, we can conclude that out of the given options, the transmission of heat without any contact.

A gas sample has volume 3.00 dm3 at 101
vivado [14]

Answer:

21.3dm³

Explanation:

Given parameters:

Initial volume of gas = 3dm³

Initial pressure  = 101kPa

Final pressure  = 14.2kPa

Unknown

Final volume  = ?

Solution:

To solve this problem, we use the Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

Mathematically;

                P₁ V₁  = P₂ V₂

P and V are pressure and Volume

1 and 2 are the initial and final states

Now insert the parameters and solve;

         101 x 3 = 14.2 x V₂  

                  V₂  = 21.3dm³

Consider the sulfur difluoridemolecule.What is the central atom? Enter its chemical symbol.How many lone pairs are around the ce
olchik [2.2K]

Answer:

a. The central atom is sulfur

b. SF2

c. The central atom has two lone pairs

d. The ideal angle between the sulfur-fluorine bonds is 109.5°

e.  I expect the actual angle between the sulfur-fluorine bonds to be less than 109.5° because unbonded pairs repel bonded pairs more than bonded pairs repel other bonded pairs. So the bonds here will be pushed closer than normal
