Find the density of a material given that a 5.03g sample occupies 3.24ml

Verizon [17]

Formula for density:

D = Mass / Volume

Mass = 5.03g

Volume = 3.24ml

Formula in our case:

D = 5.03 / 3.24

$D = 0.31~g/m^{3}$

Explain what happens in the reaction between sodium hydroxide and hydrochloric acid.Explain how protons are donated and accepted

Artyom0805 [142]

Answer:

Hydrochloric acid and sodium hydroxide interact, resulting in salt and a release of heat. As we can see, the result of the interaction of two highly aggressive compounds is table salt and water – compounds that are ultimately harmless, even beneficial, to human beings.

2) An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond.A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids. A reaction between an acid and base is called a neutralization reaction.
