The combines law of gas is:
P1 * V1 P2 * V2
---------- = -----------
T1 T2
So, you can obtain many equivalent valid forms depending on the variable that you solve for.
These are some examples:
Solve for T1:
T1 = T2 * (P1 * V1) / (P2 * V2)
Solve for V2:
V2 = V1 * (T2 / T1) * (P1 / P2)
Solve for P1:
P1 = P2 * (T1 / T2) * ( V2 / V1)
Photosynthesis is the process by which CO₂ is converted to an organic compound. The complete reaction is as follows;
6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂
stoichiometry of CO₂ to C₆H₁₂O₆ is 6:1
For 1 mol of C₆H₁₂O₆ to be formed - 6 mol of CO₂ is required
Therefore for 3.21 mol of C₆H₁₂O₆ to be formed - 6 x 3.21 mol of CO₂ required
Number of moles required are - 19.26 mol of CO₂
Answer:
the answer is d which is soap solution because it's a soap solution that can measure the degree of hardness of a water if the water forms with this soap solution then the water is hard but if the water forms foam with soap then it is soft
Answer:
All isotopes have 24 protons.
Explanation:
Isotope:
The isotope of an element have same number of protons but different number of neutrons.
In given question chromium has four isotopes Cr-50, Cr-52, Cr-53 and Cr-54.
In each isotope the number of protons are 24 but the number of neutrons are different.
The number of protons are also equal to the number of neutrons and it is also the atomic number so the atomic number of all chromium isotope is same.
The number of neutrons in Cr-50 = 50-24= 26
So, chromium 50 has 26 neutrons.
The number of neutrons in Cr-52 = 52-24= 28
So, chromium 52 has 28 neutrons.
The number of neutrons in Cr-53 = 53-24= 29
So, chromium 53 has 29 neutrons.
The number of neutrons in Cr-54 = 54-24= 30
So, chromium 54 has 30 neutrons.
