Answer:
41.56 g
Explanation:
Given data:
Mass of NH₄Cl = 15.50 g
Actual yield of AgCl = 35.50 g
Theoretical yield of AgCl = ?
Solution:
Chemical equation:
NH₄Cl + AgNO₃ → AgCl + NH₄NO₃
Number of moles of NH₄Cl:
Number of moles = mass/ molar mass
Number of moles = 15.50 g/ 53.491 g/mol
Number of moles = 0.29 mol
Now we will compare the moles of NH₄Cl with AgCl .
NH₄Cl : AgCl
1 : 1
0.29 : 0.29
Theoretical yield of AgCl:
Mass = number of moles × molar mass
Mass = 0.29 mol ×143.32 g/mol
Mass = 41.56 g
Answer:
They represent the valence electrons, so s and p sublevels only! This does not include the d block!
Answer:
Ionic bonds result from the mutual attraction between oppositely charged ions. They tend to be stronger than covalent bonds due to the coulombic attraction between ions of opposite charges.
Explanation:
Answer:
an article on the beneficial bacteria in yogurt, featured in Medical Journal of Gastroenterology
Explanation:
This article is published in a Medical Journal, which means the contents must be credible, informative, and accurate. In order to be these things, the author most likely had others review their writing to remain objective and ensure quality work. The other articles are not meant to solely inform and are featured in less credible magazines. Therefore, the third option is correct.
It's sodium chloride.
sodium chloride is table salt which is a pure substance. it's a compound but not a mixture.
note that iodized salt is a mixture, but we're just talking sodium chloride here.
