Answer:
Mixture of two elements
Explanation:
You can tell that it is an element since the atoms are only bonded to atoms of the same type. It is a mixture since the molecules are together in solution but aren't bonded together.
A. 4 mm.......0.5 mm
B. 1.5 mm......same size
Answer:
Bq/m3 (becquerels per cubic meter) or pCi/l (picocuries per litre)
Explanation:
The unit of the International System of Units identified to measure radioactive activity is Becquerelio (Bq) and equivalent to one decay per second.
The Curio (Ci) is also a radioactivity unit, which is still being used in some countries. It owes its name to chemists and chemists Pierre and Marie Curie.
It represents the amount of material in which 3.7 × 1010 atoms per second, or 3.7 × 1010 nuclear decays per second, which is roughly the activity of 1 g of 226Ra (isotope of the chemical chemical element).
The equivalence between the two is:
1Ci= 3,7 × 1010Bq
The specific radioactive activity of a radioactive gas such as radon gas is measured per unit volume and measured in Bq/m3 or pCi/l.
In this case the equivalence is:
1pCi/l= 37Bq/m3
Answer:
I hope it help you the wavelength is 1.9130E-28
Answer:
the molecules of each substance attract each other through dispersion (London) intermolecular force.whether a substance is solid, liquid or gas depends on the balance between the kinetic energies of the molecules and their intermolecular attractions.
thank you.
