Explanation:

The atomic mass of an element is 32.07 u and its atomic number is 16. The number of protons contained in the nucleus of an atom of this element is (A) 16
(B) 31
(C) 32
(D) 48

Answers

I THINK IT IS 16 BECAUSE THE ATOMIC NUMBER AND THE NUMBER OF PROTONS ARE THE SAME

atomic number = number of electrons = number of protons( by JJ thomson's theory)

Thus, the number of protons is 16

making predictions, categorizing things, spotting something unusual, identifying themes, discovering connections, finding patterns are all apart of?

Which of the notations below is another way to write the name of the following nuclide?A.iodine-53

B.iodide-53

C.iodide-127

D.iodine-127

Answers

Answer: D.iodine-127:

Explanation:

1) As per the definition of nuclide, it is the atomic spieces (the atom) characterized by the nucleons (protons and neutros).

2) To notation for a nuclide is the name of the atom followed by a hypen (without blank spaces) and the mass number.

3) The mass number is the sum of protons and neutrons.

4) From that, you can tell this about the four choices given:

A.iodine-53: is not correct because that would mean that the mass number is 53, which cannot be right as the atomic number of iodine is 53 meaning that it has 53 protons, and so that notation is not including the neutrons.

B.iodide-53: is not correct because the name of the atom is iodine, not iodide (also the mass number cannot be for the same reason explained above)

The name iodide is reserved for the ions from iodine not for the atom.

C.iodide-127: incorrect due to the name iodide, for the same reason explained above.

D.iodine-127: this is correct choice. It is the name of the isotope of the iodine with mass number 127, which means that the atom has 53 protons and 74 neutrons (53 is the atomic number and 74 is calculated from 127 - 53)

iodine-127

Answers

Answer: The equilibrium concentration of $CH_4$ , expressed in scientific notation is $5.9* 10^(-2)M$

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

The given balanced equilibrium reaction is,

$CO(g)+3H_2(g)\rightleftharpoons CH_4(g)+H_2O(g)$
