Answer:

3.46*10⁻²² kJ

Explanation:

By the Avogadro's number, 1 mole of electrons at 1 mole of atoms correspond to 6.02x10²³ electrons. So it's necessary 208.4 kJ to remove 6.02x10²³ electrons. To remove a single electron:

6.02*10²³ electrons ---------------- 208.4 kJ

1 electron                  ---------------- x

By a simple direct three rule:

6.02*10²³ x = 208.4

x = 3.46*10⁻²² kJ

Answer:

8.38×10raise to power 23

Explanation:

mass of sugar=density ×volume

=. 1.59g/ml×25ml=39.75

no. of miles= given mass/ molar mass

= 39.75/342.3g / mole

1 mole of sugar =C12 H22 O11

contains

12× 6.023 × 10 ∆23=72.28× 10∆ 23 ×6.023×10²³

= 8.38× 10²³

2: Their big eyes help them to spy objects in dark depths where most other animals would see nothing

3: Until 2005, nobody had ever seen a giant squid that was alive.

4: According to the stories, an huge squid would wrap its arms around a whale, causing a terrible fight to start. 
5: Giant squid have small fins at the rear of their mantles used for locomotion. 


Human IMPACT

Not only can squids and octopuses sense sound, but as it turns out, these and other so-called cephalopods might be harmed by growing noise pollution in our oceans—from sources such as offshore drilling, ship motors, sonar use and pile driving.
