Ca(NO3)2(aq) + Na2CO3(aq) → 2NaNO3 + CaCO3⬇. NaNO3 is solution so CaCO3 is the precipitate formed.

Answer:The precipitate formed is calcium carbonate.

Explanation:

double replacement reaction is the chemical reaction in which two reactant exchanges their respective ions to give new substance as a product.

AB+CD→CB+AD

In a given reaction:

$Ca(NO_3)_2(aq)+Na_2CO_3(aq)\rightarrow 2NaNO_3(aq)+CaCO_3(ppt)$

When calcium nitrate reacts with sodium carbonate in aqueous they give white colored precipitate of calcium sulfate and aqueous solution of sodium nitrate.

Answer:

2.24 seconds

Explanation:

xf = xo + vo t + 1/2 at^2

45 = 0 + 15 t + 1/2 (4.5) t^2

2.25 t^2 + 15t - 45 = 0 Quadratic formula shows t = 2.24 seconds

If the velocity of a moving object decreases from 60 m/s to 30 m/s, what happens to its momentum?

amid [387]

Hello!

momentum is p=mv so if the velocity is decreased by a factor of 2, which is 1/2 the value, then the momentum of that object will decrease by the same factorial.

Hope this helps, any questions please ask. Thank you!
