Answer: Amount of sodium chloride produced is 25.43 grams.
Explanation:
To calculate the moles:
Given: Mass of sodium = 10 g
Molar mass of sodium = 23g/mol
The balanced equation is:
By Stoichiometry of the reaction,
2 moles of sodium produces 2 moles of sodium chloride
So, 0.4347 moles of sodium will produce = of sodium chloride.
Molar mass of sodium chloride = 58.5 g/mol
Putting values in equation 1, we get:
Hence, amount of sodium chloride produced is 25.43 grams.
I think that, considering that a mole contains an Avogadro's number of elements, there should be 6.2× an Avogadro's Number of atoms of Al. 6.2×6.022×1023=3.733×10<span>24 atoms</span>
Answer:
3.
Explanation:
Hello,
In this case, it is convenient to write the chemical reaction as:
Which balanced turns out:
Thus the number that should be in front of the calcium sulfate is 3 in order to balance the reaction.
Best regards.
Answer:
0.447 pounds
Explanation:
The density of Mercury in grams/mL is 13.55 - I multiplied that by the volume and got approximately 203.25 grams, I then turned it into Kilograms and multiplied by 2.2 lbs / kg.
Acidity is caused by a losing <span>H+</span><span> ions. How acidic a substance is depends on how easily it will split with the hydrogen ions in water.
In your question, carboxylic acids are the most acidic because they have two oxygen atoms on the carbon to which the carboxyl group is attached, whereas the alcohol only has one and the alkyne has none, like I said earlier, this makes the hydrogen ion partially positive and therefore easier to lose.
