To find the experimental value I believe we add up all the temperatures found by each trial and divide by the number of trials
When added up and divided up this is 50.7 C
Then we continue with accepted value minus experimental value over accepted
53.0 - 50.7 / 53.0 x 100
4.3% percent error
Answer:
Explanation:
Hello,
Here, by using the Dalton's law, we can quantify the total pressure of a gaseous mixture by knowing the partial pressure of each gas, in case, hydrogen, helium and argon:
In such a way, since we actually know the partial pressure of helium and argon, and the total pressure, we can compute the partial pressure of hydrogen as shown below:
Best regards.
What exactly is the project about ?????
If 3 neutrons and 89 Se are produced from the nuclear fission of 235 U, the other fission product is Cesium-143.
<h3>What is nuclear fission.</h3>
Nuclear fission is a nuclear reaction in which a large nucleus splits into smaller ones with the simultaneous release of energy.
According to this question, a radioactive element called Uranium-235 undergoes nuclear fission to produce 3 neutrons and selenium-89.
Neutron has the following chemical symbol: 1/0 n, hence, three neutrons will be 3/0n.
Therefore, the mass number of the other fission product will be 235 - 89 - 3 = 143, which is a radioactive element called Cesium.
Therefore, if 3 neutrons and 89 Se are produced from the nuclear fission of 235 U, the other fission product is Cesium-143.

Therefore the largest atoms are on the left and the smallest on the right. So sodium (Na) has the largest atomic radius, as the valence electrons are the least attracted to the nucleus
