Answer:
30 moles of CO₂
Explanation:
balanced equation ,
CS₂+3O₂ → CO₂+2SO₂
From equation, 3 moles of O₂ are needed to make 1 mol of CO₂.
This means to produce 1 mol of CO₂, we need 3 moles of O₂, then how many moles of CO₂ will be produced from 90 moles of O₂ ?
Use unitary method to solve such problems,
Number of moles of CO₂ that will be produced:
=
=
= 30 moles of CO₂
Answer:
The isotope notation for an ion of silver-109 with a charge of positive 1 is .
Explanation:
The elements with same atomic number with different mass numbers are called isotopes.
The isotopes of silver is as follows.
From the above two isotopes have same atomic number and different mass number.
From the given,the isotope notation for an ion of silver-109 with a charge of positive 1
It can be represented is as follows.
General representation of isotope is as in attachment.
