Explanation:

The net ionic equation of a reaction is obtained from the complete ionic equation after removing the spectator ions.

The balanced chemical equation for the reaction of sodium bicarbonate with acetic acid is shown below:

$NaHCO_3(aq)+CH_3COOH(aq)->CH_3COONa(aq)+H_2O(l)+CO_2(g)$

The complete ionic equation is:

$Na^+(aq)+HCO_3^-(aq)+CH_3COO^-(aq)+H^+(aq)->CH_3COO^-(aq)+Na^+(aq)+H_2O(l)+CO_2(g)$

The net ionic equation is:

$HCO_3^-(aq)+H^+(aq)->H_2O(l)+CO_2(g)$

Answer:The net ionic equation is shown below:

$HCO_3^-(aq)+H^+(aq)->H_2O(l)+CO_2(g)$

From goal line to goal line, a football field is 300 ft long. If a player catches the ball while standing on one goal line, runs

KATRIN_1 [288]

Answer:

The player ran 91.44m.

Explanation:

The problem gives you the total distance between goal line to goal line in feet, and the answer must be given in meters, so you should convert the distance the player run from ft to m, because the player run the same distance from goal line to goal line to scores the touchdown.

So, you should apply the following conversion factor:

$300ft*\frac{0.3048m}{1ft}= 91.44m$

The player ran 91.44m.

How does the process of waste removal in a unicellular organism compare to the waste removal in a multicellular organism

Sonja [21]

The digestive system of multicellular is made up of several organs that work together to break down food so that it may be used in the body. Unicellular organisms have organelles, similar to organs, which help to digest food that will be used by the cell

That's just the tip of the iceberg" is a popular expression you may have heard. It means that what you can see is only a small p

puteri [66]

Answer:

B 1.23 g/cc

Explanation:
For something to float on seawater, the density must be less than 1.03 g/mL. If the object sinks, the density is greater than 1.03 g/mL.

Let’s examine the answer choices. Keep in mind, the ice berg is mostly below the water level.

A. 0.88 g/cc
This is less than 1.03 g/cc, which would result in floating.

B. 1.23 g/cc
This is the best answer choice. The iceberg is mostly beneath the water, but some of it is exposed. The density is greater than 1.03 g/mL, but not so much greater that it would immediately sink.

C. 0.23 g/cc
This is less than 1.03 g/cc, which would produce floating.

D. 4.14 g/cc
This is much greater than 1.03 g/cc and the result would be sinking.

If you start with 6 moles of N2 and 6 moles of H2 (meaning you won't have enough of 1 of the ingredients), how many moles of NH3

Ivahew [28]

Answer:

$4molNH_3$

Explanation:

Hello there!

In this case, according to the given information it will be firstly necessary to set up the chemical equation taking place:

$N_2+3H_3\rightarrow 2NH_3$

We infer we need to calculate the moles of NH3 by using both of the moles of N2 and H2 at the beginning, in order to identify the limiting reactant:

$n_{NH_3}=6molN_2*\frac{2molNH_3}{1molN_2}=12molNH_3\\\\ n_{NH_3}=6molH_2*\frac{2molNH_3}{3molH_2}=4molNH_3\\$

Thus, since hydrogen yields the fewest moles of ammonia, we conclude that we are just able to yield 4 moles of NH3.

Regards!
