</span>You wiil find in periodic table :)
1: China is agreeably a third world country because they do not know what they should eat, they think that beating an animal and causing it pain and suffering makes the meat taste better which is very, very unjust and cruel. This disease was started where a Bio-Disease plant was, and considering coronavirus is spreading so fast and killing so many people, ( not unlike the swine flu that ALSO originated in China ) This indicates it is very possible that this disease could have been engineered. ( not unlike the swine flu either )
2: The person itself is smart, people are stupid, fearmongering, and have been weakened through the years. The moment the media said there was a pandemic, everyone ran to the nearest convenience store to buy toilet paper, then they locked themselves in their houses because people said to do so, they bought surgical masks ( that only help you if you have secondary breathing problems, because you go to take them off and touch your face ) that they HEARD will help them. MY opinion is do what makes YOU feel comfortable, you can't help other people, but you can help yourself.
3: I don't exactly understand this question, so if you could rewrite this part I could give you an answer.
Hope this helps, if not, comment below please!!!
Answer:
1.99 x 10²³ formula units
Explanation:
Given parameters:
Mass of AgF = 42.15g
Unknown:
The amount of formula units
Solution:
To solve this problem, we set out by find the number of moles in this compound from the given mass.
Number of moles = 
molar mass of AgF = 107.9 + 19 = 126.9g/mol
Number of moles = 
= 0.33 moles
1 mole of a substance = 6.02 x 10²³ formula units
0.33 moles of AgF = 0.33 x 6.02 x 10²³ = 1.99 x 10²³ formula units
11 × 44 = 484 g
mol × molar mass
If a hypothesis is stated and outcome of the experiment is what was predicted, then it supports the hypothesis. if the experiment does not support the hypothesis, then the outcome was not what was predicted.
