22. Mass=Force/acceleration or M=F/a. So the force of this equation would be 88N and the acceleration would be 4m/s^2 so the mass in the problem would be 22.

Sketch the structure of the nitrogen containing product that is formed when ethalymine reacts with water.

Igoryamba

Answer:

Here's what I get

Explanation:

Ethylamine has an N atom with a lone pair of electrons.

It can act as a Brønsted-Lowry base and accept a proton from water and become an ethylammonium ion.

The structure of the ion is shown below (there is a C atom at each of the four-way bond intersections).

Suppose you carry out a titration involving 3.00 molar HCl and an unknown concentration of KOH. To bring the reaction to its end

snow_tiger [21]

Answer: The concentration of the KOH solution is 1.01 M

Explanation:

According to neutralization law:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1$ = basicity of $HCl$ = 1

$n_2$ = acidity of KOH = 1

$M_1$ = concentration of HCl = 3.00 M

$M_2$ = concentration of KOH = ?

$V_1$ = volume of HCl = 35.3 ml

$V_2$ = volume of KOH = 105.0 ml

Putting the values we get:

$1\times 3.00\times 35.3=1\times M_2\times 105.0$

$M_2=1.01$

Thus the concentration of the KOH solution is 1.01 M
