Answer:
the reason why Mars is red is because of its regolith, or surface material, contains lots of iron oxide — the same compound that gives blood and rust their hue
<u>Answer:</u> The half life of the reaction is 1190.7 seconds
<u>Explanation:</u>
The equation used to calculate rate constant from given half life for first order kinetics:

where,
k = rate constant of the reaction = 
= half life of the reaction = ?
Putting values in above equation, we get:

Hence, the half life of the reaction is 1190.7 seconds
Answer:
Hexane
Explanation:
You have a carbon structure with only single bonds. This means that the name will end in -ane.
There are 6 carbon atoms. This means that the name will begin with hex-.
The structure is hexane.
That depends on the wave, if you're talking about sound, it makes matter move in a similar wavelength as them, a mountainous shape. Light however would make whatever matter it hits start to move in the same direction as the light's angle of approach.
Answer:
-The mole is appropriate only for counting things that are very small.
-One mole is a very large number of something.
-A molecule of water is much smaller than a grain of sand.
