These are 3 assumptions that i know for a fact. Hope this helped.
1.Gas particles are continuous, rapid, random motion. They therefore possess kinetic energy, which is energy of motion.
2.There are no forces of attraction between gas particles.
3.The temperature of a gas depends on the average kinetic energy of the particles of the gas.
Answer:
4.375 milligram
Explanation:
Applying,
A = A'(2ᵃ/ⁿ)............. Equation 1
Where A = original amount of actinium-228, A' = amount of actinium-228 left after decay, a = Total time, n = half life
make A' the subject of the equation
A' = A/(2ᵃ/ⁿ)........... Equation 2
From the question,
Given: A = 70 milligram, a = 24.52 hours, n = 6.13 hours
Substitute these values into equation 2
A' = 70/(2²⁴°⁵²/⁶°¹³)
A' = 70/(2⁴)
A' = 70/16
A' = 4.375 milligram
A.) Phosphate ion or Orthophosphate

D.) Ammonium
e.) Iron
C.) Nitrate
f.) Sulfur dioxide
Answer:
N2 + H20
Explanation:
chemical equation balancer
All of them are right except the neutron one. The neutrons is actually 176 because you subtract the number of protons from the atomic mass to find this.
