Zepler [3.9K]3 years ago
6 0

Explanation:

B. 1) Tritium is the isotope of <u>Hydrogen</u><u> </u><u>(</u><u>H)</u><u>.</u>

2) Mass of an Electron is <u>9.10938356 × 10-³¹ </u> Kg.

3) Molecular mass of Carbon dioxide (CO2)

=><u> Molecular mass of carbon = 12g</u>

<u>Molecular mass of oxygen= 16g</u>

<u>molecular mass of CO2 = [12 + (16 X 2)]g</u>

= <u>(12 + 32)g</u>

= <u>44 g</u>

4) Dalton has given its Atomic Theory in the year <u>1803.</u>

5) Nucleus is discovered by

= <u>Ernest Rutherford discovered the nucleus of the atom in 1911.</u>

<em><u>hope</u></em><em><u> this</u></em><em><u> helps</u></em><em><u> you</u></em><em><u>.</u></em>

How many electrons occupy p orbitals in a bismuth atom?
Ahat [919]
Atomic number Bi = 83 
electron configuration Bi : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p3 

p orbitals = 3p6, 4p6, 5p6 and 6p3 
so, 6 + 6 + 6 + 3 = 21 electrons

Seawater, which covers the majority of the earth, is composed primarily of molecules of H2O and equal numbers of Na ions and Cl-
Vsevolod [243]

Explanation:

Species present are H_{2}O(l), Na^{+}(aq) and Cl^{-}(aq). Now, we will calculate the number of componenets present as follows.

                C = n - E

where,   E = number of independent equations

              n = number of phases present

Therefore, we will calculate the number of components as follows.

                        C = 3 - 1

                            = 2

Since, sodium chloride (NaCl) will tend to form a homogeneous mixture in water. Therefore, phase will be equal to 1.

Therefore, it means that there are two components present in one phase.
