Determine the charge on the cation and anion. If the cation has a Roman numeral after it, that is the charge on that cation. ...
Determine formula.
Answer:
5.5 moles of sodium are produced
Explanation:
Given data:
Number of moles of hydrogen = 2.75 mol
Number of moles of Na produced = ?
Solution:
Chemical equation:
H₂ + 2NaCl → 2HCl + 2Na
Now we will compare the moles of hydrogen and sodium from balance chemical equation:
H₂ : Na
1 : 2
2.75 : 2/1×2.75 = 5.5 mol
Thus, 5.5 moles of sodium are produced.
300g because it’s more water to heat, meaning how easy would it be to boil a cup of water? Easy. What about a pool? See what I mean, bigger the area lesser the warmth it gets.
Answer:
An increase in temperature will result in increase in the average kinetic energy of the reacting particles(atoms). Which will therefore increase the frequency of their collision....
Using collision theory
The reaction rate increases......
That friend is not correct. Physical change is characterized by a change in appearance without any change in composition. So, if the appearance did not change in the situation, then there is no change in the system. This type of change affects the form of a substance but not the composition or the structure of the molecules. Examples of this type of change are ice melting, cutting a paper into half, clay is molded to a new shape, butter melting, water evaporating. The change that involves a change in chemical composition is classified a chemical change. In this type of change, chemical reactions would take place.
