Thallium is the new element
TI is its symbol
Atomic no. Is 81
Mass is 204.38
Answer:
The correct answer is "D".
Explanation:
The synthesis consists of extracting the most important data from a text or any source of information. To be able to synthesize it is necessary to read, understand and interpret the message or arguments presented. Once these factors have been extracted, they are brought together to form a coherent text that in a few words explains the original text.
Have a nice day!
Answer:
a. BaCl2 is ionic compound.
b. CH4 is covalent compound.
b. MnO2 is ionic compound.
e. H2S is covalent compound.
c. H3AsO4 is ionic compound.
f. CH3OH is covalent compound.
Explanation:
BaCl2, MnO2 and H3AsO4 are ionic compounds due to the presence of ionic bond between the atoms while on the other hand, CH4, H2S and CH3OH are covalent compounds due to the presence of covalent bond between their atoms. In covalent bonds, sharing of electrons occur whereas in ionic bonds, complete transfer of electrons occur from one atom to another atom.

Answer:
5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
Explanation:
Given data:
Moles of NO formed = ?
Moles of N₂ reacts = 2.86 mol
Solution:
Chemical equation:
N₂ + O₂ → 2NO
Now we will compare the moles of nitrogen with nitrogen oxide from balance chemical equation.
N₂ : NO
1 : 2
2.86 : 2/1×2.86 = 5.72 mol
So 5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
