- The student weighs out 0.0422 grams of the metal magnesium, thus we can figure that the more's, the magnesium he used, is the mass of the magnesium over the more mass, which is 0.024422.
- That is approximately 0.001758.
- Furthermore, it claims that too much hydrochloric acid causes the metal magnesium to react, producing hydrogen gas.
- The volume of collected gas is 43.9 cc, the mastic pressure is 22 cc, and a sample of hydrogen gas is collected over water in a meter.
<h3>Is it true that calculations made utilizing experimental and gathered data result in a percent error? </h3>
- Consequently, we are aware that magnesium and chloride react.
- We create 1 as the reaction ratio is 1:2.
- The hydrogen and 1 are more.
- Magnesium chloride is more.
- Therefore, based on this equation, we can infer that the amount of hydrogen that would be created in this scenario is greater than the amount of magnesium present here, or 0.001758 more.
- Among hydrogen, there is.
- \Once we convert the temperature from 32 Celsius to kelvin, we can tell you that the temperature is actually about 5.15 kelvin.
- The gas has a volume of 43 in m, which is equal to 0.0439 liter and indicates that the pressure is approximately 832 millimeter.
- Mercury, which is 2 times 13332 plus ca, or roughly 110922.24 par, is a mathematical constant.
- So, in this instance, we are aware that p v = n r t.
- The r in this case equals p v over n t, thus we want to determine the r.
- So p is 110922.24. The temperature is 305.15 and the V is 0.04 over the n is 0.001758.
- Let's proceed with the calculations right now.
- In this instance, you will discover that the solution is 9.077 times 10; that is all there is to it.

First we have to refer
to the reaction between the acid and the base: <span>
H2SO4 + 2 NaHCO3 ---> 2 H2O + 2 CO2 + Na2SO4
From this balanced equation we can see that for every 1 mol
of acid (H2SO4), we need 2 mol of base (NaHCO3) to neutralize it. Given 28 ml
of 5.8 M acid, we need to find out how many mols of acid that is:
<span>28mL * (1L/1000mL) * 5.8 mol/L = 0.1624 mol H2SO4</span></span>
<span>
Since we need 2 mol of base per mol of acid, we need:</span>
<span> 2*0.1624 mol = 0.3248 mol NaHCO3 </span><span>
MolarMass of NaHCO3 is 84.01 g/mol
<span>0.3248 mol*(84.01g/mol) = 27.29 g NaHCO3</span></span>
Answer:
Check Explanation
Explanation:
In this case the Mushroom would get energy from decomposing dead plants and animals in the soil/ground
The plant would get energy from the sun (simplified)
the rabbit would get energy from eating the plant
in this case the wolf would energy from eating the rabbit but in a normal setting the wolf could get energy from eating any animal
