How many atoms are in 5 moles of CH4
Answers
1 mole CH4 ------------ 16 g
5 moles CH4 ---------- x g
x = 5 . 16
x = 80 g
16 g CH4 ------------------ 6,02.10²³ atoms
80 g CH4 ------------------ y atoms
16 . y = 80 . 6.02x10²³
16 y =
y =
y =
hope this helps

Answer:
The correct answer is option d: bacteria
Explanation:
Hello! Let's solve this!
Abiotic components are those that have no life and biotics are the factors that have life.
Let's see each option!
Nutrients: they have no life, they can be calcium, protasium, vitamins
sunlight: it has no life, it comes from the sun
rain: it has no life, it is condensed water and it falls to the earth in the form of drops
bacteria: they have life, they are cells so they are living beings.
We conclude that the correct answer is option d: bacteria

Answer : The structural formula of 2-pentyne is shown below.
Explanation :
Structural formula : In the structural formula, the bonding and type of bonds which holds the atoms in molecule together are shown.
The given name of compound is, 2-pentyne.
A suffix '-yne' present at the end of the name represent the alkyne group.
For the number of carbon atom, we use prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
In this compound, the parent chain is 5 membered and a triple bond is present at 2nd position of the parent chain.
Thus, the structural formula of 2-pentyne is shown below.
