The halogens and noble gases are alike because they are all non-metallic elements, with the exception of astatine, a radioactive
Hello there! Your answer is 58 g.
The weight of something on the moon is approximately 1/6th of it's weight on earth. To find the weight of an object on the moon when you are given the Earth value, divide the earth value by 6 to get 1/6th of it's value.
352/6 = 58 g
So, there is your final answer. Something that weighs 352 g on Earth weighs 58 g on the moon. I hope this helps and have a great rest of your day!
Answer:
Part A: 27.8 L; Part B: 0.500 mol
Explanation:
Part A
For an ideal gas, we can use the equation:
PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.
In the beggining:
P*48.0 = 1.90*RT
P/RT = 1.90/48.0
P/RT = 0.03958
For constants pressure and temperature, after 0.800 mol of gas leaks out: n = 1.90 - 0.800 = 1.10 mol
PV = 1.10*R*T
P/RT = 1.10/V
0.03958 = 1.10/V
V = 1.10/0.03958
V = 27.8 L
Part B
In the beginning
PV = nRT
P*70.0 = 2.00*RT
P/RT = 2.00/70.0
P/RT = 0.02857
After the gas leaked out:
PV = nRT
P*17.5 = nRT
P/RT = n/17.5
0.02857 = n/17.5
n = 0.500 mol
SO4 -2, or Sulfate
Hope this helps! :)
The rate of formation of water and the decomposition of hydrogen peroxide is double as compared to rate of formation of oxygen.
<h3>What is chemical reaction?</h3>
The chemical reaction is given as the reaction of the reactants in the process to form the new compound.
The chemical reaction with the decomposition of hydrogen peroxide is:
The rate of formation of water is given to be double the rate of formation of oxygen as 2 moles of water formed with 1 mole of oxygen.
The rate of disappearance of hydrogen peroxide is double with formation of oxygen as for decomposition of 2 moles of hydrogen peroxide, 1 mole of oxygen is formed.
