Answer:Density (ρ) = 7.1538461538462 kilo
Explanation:ρ =
m
V
=
9.3 gram
1.3 liter
= 7.1538461538462 gram/liter
= 7.1538461538462 kilogram/cubic meter
Compared to sulphuric acid, carboxylic acids are much weaker, this is because of their overall characteristic with respect to pKa, they do not dissociate completely as to all be in their conjugate base form but will have equal amounts in both.
Sulfuric acid is a strong polyprotic acid, and has a pKa value that is even smaller than the carboxylic acid.
Use stoichiometry to solve this problem. We know that 1.00 mole of CuO is (about) 45g, and we also know that the ratio of CuO to Cu is 1:1, meaning that 1 mole of CuO can be used to produce 1 mole of Cu. Look up the molar mass of Cu on the periodic table to see the answer.
The answer is friction. It oppose the ball's forward motion. The cause for a ball rolling across a rug to slow to a stop is that friction resists the ball's forward motion. Friction<span> can cause a </span>moving<span> object, such as a </span>ball<span>, to slow down and eventually stop.</span>
