Carbon and fluorine have the same shielding effect True or False

Chemistry
1 answer:
iragen [17]3 years ago
7 0

Answer:

true

Explanation:

There are two electrons (in the 1s orbital) on both carbon and fluorine “shielding” the outer electrons from the full force of the nucleus and due to both atoms being approximately the same size (both period two) then it is this shielding effect and proton difference that is causing the electronegativity difference

What do the following results from the TEST FOR LIFE tab indicate about the sample?
Tcecarenko [31]

The result for TEST FOR LIFE is that the sample produces ATP. The sample is plant.
D Is going to be your answer

Explanation:
The chloroplasts are cell structures that are photosynthesis. The Golgi apparatus is the site transport of substance out of the cell. Mitochondria is the site of cellular respiration.
The two main functions of organelle is that it stores the herediatary material, DNA and it coordinates the cell's activities like growth, intermediary metabolism, protein synthesis, and reproduction. Eukaryotes are the cells of advanced organisms have a nucleus.
The results of the sample produces ATP, the sample is plant and the plant cells have an envelope surrounding the nucleus.

Hope this helps.!!! And please mark brainliest thank you!!

How many moles are 21.67 L of NH4CI?
Gnoma [55]

Answer:

0.967mole

Explanation:

Given parameters:

Volume of NH₄Cl  = 21.67L

Unknown:

Number of moles  = ?

Solution:

If we assume that the volume was taken at standard temperature and pressure,

 Then;

  Number of moles  = \frac{volume }{22.4L}  

 Number of moles  = \frac{21.67}{22.4}   = 0.967mole

Calculate the work (kJ) done during a reaction in which the internal volume contracts from 85 L to 12 L against an outside press
butalik [34]

Answer:

The work done on the system is 17.75_KJ

Explanation:

To solve this question we need to know the required equations from the given variables, thus

Initial volume = 85L

Final volume = 12L

External pressure = 2.4 atm.

work done = - PΔV

2.4×(85-12) = 175.2L×atm

Converting from L•atm to KJ is given by

1 L•atm = 0.1013 kJ

(175.2 L•atm) * (0.1013 kJ / 1 L•atm)

= 17.75 kJ

The work done on the system is 17.75_KJ
