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.
Answer:
103.4 moles of hydrogen
Explanation:
Given data:
Moles of C₁₂H₂₂O₁₁ = 4.70 mol
Number of moles of hydrogen present = ?
Solution:
one mole of C₁₂H₂₂O₁₁ contain 22 moles of hydrogen. Thus in order to determine total number of moles in 4.70 moles of C₁₂H₂₂O₁₁ we will multiply the 22 moles of hydrogen with 4.70 moles of C₁₂H₂₂O₁₁.
1 mole of C₁₂H₂₂O₁₁ = 22 moles of Hydrogen
4.70 × 22 moles
103.4 moles of hydrogen
Nature is full of wonders and one of the most impressive of them are symbiotic relationships (mutually beneficial relationships). Despite the competition in the kingdom of life, here 2 actors help each other to gain more than they could individually. Let's look at the answers. The sea anemone can't possibly fertilize the clownfish's eggs, only another clownfish can do that. The 4th choice might be correct but it does not help the clownfish; The 5th choice is also correct but it is not related to the offspring of the clownfish. For the 3rd choice, we have that the anemone sometimes provides leftovers for the fish, but the fish' eggs cannot use this source of nutrients. However, we know that the 1st assertion holds; the poisonous tentacles of the sea anemone protect the eggs from potential predators.
