The force of gravity is the force with which massively large objects such as the earth attracts another object towards itself. All objects of the earth exert a gravity that is directed towards the center of the earth. Therefore, the force of gravity of the earth is equal to the mass of the object times acceleration due to gravity.
<span>F = ma </span>
<span>4.9N = m (9.8 m/s^2), note that N (newtons) = kg-m/s^2 </span>
m = 0.5 kg
<span>The mass of the object is 0.5kg.</span>
Answer:
Answer is attached but read below for full explanation.
Explanation:
This reaction is called Hydrolysis of Amides. Amides are carboxylic acid derivatives where the -OH of the carboxylic acid has been replaced by -NH2, -NHR, or -NR2 of an amine. Since the reaction between a carboxylic acid and an amine to give an amide also liberates water, this is an example of a "condensation reaction".
A solution with hydroxide ion concentration of 4.15 x10^-6 m is basic and has a hydrogen ion concentration of 2.41 x10^-9 M
we well know thaat (H^+) (OH^-) = 1 x10^-14
by making H^+ concentration the subject of the formula
H^+ = 1 x10^-14/OH^-
H^+= 1 x10^-14/4.15 x10^-6 = 2.41 x10^-9 M
the solution is basic since OH^- ion is for basic solution
Something that breaks with little force against it.
