To arrange these elements according to the atomic radius (smallest to largest) would be:
Be, Mg, Ca, Sr, Ba
Answer:
, The partial pressure of O2 is = 21 atm
Explanation:
The concept is the pressure exerted by each gas is independent of one another or in other words independent of the pressure exerted by all other gases present.
This means that total pressure is the sum of the individual pressure of each gas by dalton's law.
So, putting the given values we get
43 = P_O2 +15+7
P_O2 = 21 atm
Therefore, The partial pressure of O2 is = 21 atm
Answer: 25°C=77°F
Explanation:
FORMULA
F=9/5 C+32
-----------------------------------
Given: C=25°
F=9/5 C+32
F=9/5 (25)+32
F=45+32
F=77°
Hope this helps!! :)
Please let me know if you have any question
Answer is: Reactants: 2VCl2 and 3Cl2; product: 2VCl5.
Balanced chemical reaction: 2VCl₂ + 3Cl₂ → 2VCl₅.
According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.
There are ten chlorine atoms and two vanadium atoms on both side of balanced chemical reaction.
2.17 x 10²³molecules
Explanation:
Given parameters:
Number of moles of water = 0.36moles
Unknown:
Number of molecules in a water sample = ?
Solution:
A mole of substance is the amount of substance that contains the Avogadro's number of particles which is 6.02 x 10²³ particles.
The particles are molecules, formula units, number of protons, neutrons, electrons, e.t.c;
Since 1 mole of any substance = 6.02 x 10²³ molecules
0.36 moles of water = 0.36 x 6.02 x 10²³ = 2.17 x 10²³molecules
