1 mole tungsten ------------- 6.02 x 10²³ atoms
0.0845 moles ---------------- ( atoms tungsten )
atoms tungsten = 0.0845 x ( 6.02 x 10²³) / 1
atoms tungsten = 5.08 x 10²² / 1
= 5.08 x 10²² atoms of tungsten
hope this helps!
Answer:
0 g.
Explanation:
Hello,
In this case, since the reaction between methane and oxygen is:

If 0.963 g of methane react with 7.5 g of oxygen the first step is to identify the limiting reactant for which we compute the available moles of methane and the moles of methane consumed by the 7.5 g of oxygen:

Thus, since oxygen theoretically consumes more methane than the available, we conclude the methane is the limiting reactant, for which it will be completely consumed, therefore, no remaining methane will be left over.

Regards.
The correct answer is option 4. One benefit of nuclear fission reactions is the production of energy. Fission reaction is one type of nuclear reaction. This type occurs when a nuclei is being divided. <span>Fission reaction takes place in any of the heavy nuclei after
capture of a neutron. </span>
They release spores into the air, often carried by the wind. They allow spore bearing plants to replicate themselves in a form of cloning.
Answer : The correct option is, 
Explanation :
- Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. That means, the loss of electrons takes place.
Or we can say that, oxidation reaction occurs when a reactant losses electrons in the reaction.
- Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.
Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.
According to the electrochemical series,
most likely to be reduced because
Hence, the ion most likely to be reduced is
.
