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.

Explanation:

You have to check a 12 year olds respiration rate by Siting them down and trying to relax.  It's best to take the respiratory rate while sitting up in a chair or in bed.  Measure their breathing rate by counting the number of times their chest or abdomen rises over the course of one minute.  Then Record this number. Now you have to answer the first few  questions based on that.

Heart rate, blood pressure, respiratory rate and temperature are the big four vital signs.

8.  Secondary assessments are used in order to determine the injury, how the injury occurred, how severe the injury is, and to eliminate further injury and that is why it is important.

9. It should only be performed when a person shows no signs of life or when they are unconscious, unresponsive, not breathing or not breathing normally.  

In order to perform CPR, you need to check the scene and the person. Make sure the scene is safe, then tap the person on the shoulder and shout "Are you OK?" to ensure that the person needs help. Then pen the airway,  Check for breathing,  Push hard, push fast, deliver rescue breaths, continue CPR steps.

An athlete completes 1 laps around a track with a radius of 25 meters in 180 seconds. What is the magnitude of the athlete's tan
DanielleElmas [232]

Answer:

0.872<em>m/s</em>

Explanation:

Tangential velocity is given by the formula,

v= 2\pi r/ t

In the question given,

radius= 25meters

time= 180secs

pie= 3.14

number of laps= 1

The magnitude of tangential velocity equals;

\frac{1lap* 2 *3.14 *25m}{180secs}

<em>v </em>= 157<em>m</em>/180<em>secs</em>

Therefore, the magnitude of the tangential velocity

=0.872<em>m/secs</em>
