Answer:
Acetamide
Explanation:
The reaction can be expressed as:
CH₃COOH + NH₃ → CH₃CONH₂ + H₂O
It's worth mentioning that this reaction would have a better yield if we use an appropiate catalyst such as DCC, in order to prevent an acid-base reaction and instead have the previous <em>amidation</em> reaction.
Answer:
25.8
Explanation:
Let's write the reaction between magnesium-phosphide and potassium:
Mg3P2 + K = Mg + K3P
And now let's balance this equation:
Mg3P2+6K=3Mg+2K3P
We see that the ratio of magnesium-phosphide and potassium is 1:6, which means that for every mole of magnesium-phosphide there need to be 6 moles of potassium.
Since we have 4.3 moles of Mg3P2, there need to be 6 • 4.3 = 25.8 moles of potassium.

A double-edged stainless steel can float on water. Without surface tension, the blade would sink because its weight is greater than its buoyant surface.
Answer: The blade doesn't sink because of the surface tension of the water.
