Chemistry
1 answer:
Vadim26 [7]2 years ago
3 0

Answer:

C3 H6 O2

Explanation:

first divide their mass by their respective molar mass, we get:

30.4 moles of C

61.2 moles of H

20.25 moles of O

now divide everyone by the smallest one of them then we get

C= 1.5

H= 3

O= 1

since our answer of C is not near to any whole number so we will multiply all of them by 2

so,

C3 H6 O2 is our answer

How many moles of silicon are in 5.9 X 10 to the 24 power atoms of silicon​
Dimas [21]

Answer:

9.79740949850 moles

Explanation:

  • 1 mole = Avogardo's Number <<6.022 E 23 <<particles, atoms, etc.>>
  • This problem can be solved using dimensional analysis by multiplying atoms (5.9E24 atoms) by (1) mole and then dividing the number by Avogardo's number (6.022 E 23 atoms).
  • Note: E = * 10

Side Note: Please let me know if you need any clarifications about this!

What is the best conclusion according to the energy diagram of the chemical reaction?
Mariulka [41]

"The reaction will absorb energy" is the best conclusion according to the energy diagram of the chemical reaction.

<u>Option: B</u>

<u>Explanation:</u>

The chemical bonds in the reactions are broken and formed as per process and contributed by three major steps: reactants, transition phase and product formation. Here transition phase is in equilibrium stage drived by activation energy, where bond is partially formed and partially broken, located at higher energy level then the starters.

The reactant's energy level is less relative to the products as seen in the endothermic reactions' energy diagram, which depicts that  the products are less balanced than reactants. Here when the reaction is forced to the forward direction, then it direct towards the more unbalance entities. As energy is absorbed in the endothermic reaction from surrounding, thus the enthalpy change (ΔH) for the reaction is positive.
