hope it helpsss

This repulsion is stronger than the repulsion between the lone pair and the three bond pairs on the nitrogen atom. Since the repulsions on the bond pairs in H2O molecule are greater than that in NH3, the bond angle in water is less than that of ammonia.also thats the reaso why ammonia has hig bond angle than water.

A 200.-milliliter sample of CO2(g) is placed in a sealed, rigid cylinder with a movable piston at 296 K and 101.3 kPa. Determine

bagirrra123 [75]

Answer:

The final volume of the sample of gas $V_{2}$ = 0.000151 $m^{3}$

Explanation:

Initial volume $V_{1}$ = 200 ml = 0.0002 $m^{3}$

Initial temperature $T_{1}$ = 296 K

Initial pressure $P_{1}$ = 101.3 K pa

Final temperature $T_{2}$ = 336 K

Final pressure $P_{2}$ = K pa

Relation between P , V & T is given by

$P_{1} \frac{V_{1} }{T_{1} } = P_{2} \frac{V_{2} }{T_{2} }$

Put all the values in the above equation we get

$101.3 (\frac{0.0002}{296} )= 152 (\frac{V_{2} }{336} )$

$V_{2}$ = 0.000151 $m^{3}$

This is the final volume of the sample of gas.

Solnce55 [7]

Answer:

ust use the equation

M1 X V1 = M2 X V2

where M1 is the initial concentration, V1 the volume of M1, M2 the final concentration and V2 the final volume. Here you are looking for V1 so, first solve for V1 and put in the numbers.

V1 = (M2 X V2)/M1 = (3 X 0.5)/18 = 0.5/6 = 0.083 L or 83 mL

Describe how you might prepare disodium phosphate given a solution of phosphoric acid, 0.500 molar and a solution of sodium hydr

PilotLPTM [1.2K]

Explanation:

When 2 moles of sodium hydroxide (NaOH) reacts with 1 mole of phosphoric acid (H3PO4) it gives 1 moles disodium phosphate Na2HPO4 and 2 moles of water.

0.5 molar solution indicates half moles of molecules are present in per ltr solution.

to prepare disodium phosphate you need to dilute phosphoric acid solution to 0.25 molar and add equal quantity of 0.5 molar solution.

$2 NaOH + H_3PO_4 \: \rightarrow \: Na_2HPO_4 + 2 H_2O$
