Among the options, iodine is a solid ,bromine is liquid while fluorine and chlorine are gases.
Chlorine is greenish yellow colored gas while fluorine is pale yellow, chlorine is used as a disinfecting agent and oxidizing agent as well.
Answer:
The half-life of Material 1 and Material 2 are equal.
Explanation:
Material 1 disintegrates to half its mass three times in 21.6 s, to go from 100g
to 12.5g. That is,
100g - 50g - 25g - 12.5g
Material 2 disintegrates to half its mass three times in 21.6 s, to go from 200g to 25g. That is,
200g - 50g - 25g - 12.5g.
This means that regardless of their initial masses involved, material 1 and material 2 have equal half-life.
Their half-life is 21.6 ÷ 3 = 7.2 sec
Kr 4d10 5s2 5p2 would be your answer.
In chemistry for an chemical equation to be complete it has to be balanced using appropriate coefficients and state symbols such similar atoms are equal in both sides of the equation. The reaction between hydrogen sulphide and oxygen gas yields sulphur iv oxide and water as indicated by equation.
2H2S (g) + 3O2 (g) = 2SO2(g)+ 2H2O(l).
therefore the correct answer is 2,3,2,2
Answer:
There is no picture but the one that is in motion in the picture has kinetic energy.
Explanation:
Kinetic energy is the energy of motion.
