Naya [18.7K]3 years ago
8 0

Answer: 18 atoms

Explanation: the reactant contains 6O2 and 6O and this gives a total of 18

8 0

Answer:

The correct option is 18

Explanation:

There are two reactant specie in the equation; carbon dioxide (CO₂) and water (H₂O). From the equation, there are 6 molecules of CO₂, hence the number of oxygen atoms from CO₂ is <em>6 × 2 = 12</em> and there are also 6 molecules of H₂O, hence the number of oxygen atoms from H₂O is <em>6 × 1 = 6</em>.

The total number of oxygen atoms in the reactants is therefore 12 + 6 = 18

If an area has high air pressure and low humidity, what type of weather will it most likely have?
elixir [45]

Aloha~! My name is Zalgo and I am here to help you out today. Those sort of conditions could be fore-boding/foreshadowing/warning that there will soon be a storm or that it will rain quite a lot. In the case of it being a storm, you should be a small room where there are no windows and nothing that is small that will fly towards you that could kill you.

I hope that this helps! :D

Determine the energy in joules of a photon whose frequency is 3.55 x10^17 hz
zaharov [31]
The equation for energy of a photon is E=hv where v equals frequency and h equals the Planck constant (6.626X10^-34). So since you've been given frequency you can just plug in frequency to find the total energy in joules.

E=(3.55X10^17)(6.626X10^-34)
E=2.35223X10^-16

Not sure how many significant figures you needed. Hope this helped.

Assuming equal concentrations and complete dissociation, rank these aqueous solutions by their freezing points. K2SO4 NH4I CoCl3
katrin [286]
The substance that releases the greatest amount of ions will have the greatest attractive forces within its solution, resulting in a reduced freezing point.
K₂SO₄ yields 3 ions
NH₄I yields 2 ions
CoCl₃ yields 4 ions

Freezing points:
CoCl₃ < K₂SO₄ < NH₄I
