Answer:

BaI2

Explanation:

Barium gives a green flame test. When the halide test is conducted, a yellow precipitate indicates the presence of the iodide ion.

Also, BaI2 reacts with ammonium carbonate as shown below:

BaI2(aq) + (NH4)2CO3(aq) → BaCO3(s) + 2(NH4)I(aq)

The BaCO3(s) separates from the reaction system as a precipitate.

a truck start from attains a velocity of 20m/s after 10 second , calculate the acceleration. plz help with this ​
Marysya12 [62]

Answer:

= u +at

20m/s = 0 + a*10s

a = 20m//10s

a = 2m/s²

From the data given , it is not possible to calculate the displacement , because no direction of motion is given

But it is possible to calculate the distance travelled

Distance = ut + ½ *a*t²

distance = 0 + ½ * 2m/s * 10²s

distance = 100m
