A. represents a situation in which the person is not handling frustration well. In the other situations, the people found they weren't doing as well as they had hoped and so they actively found ways to maneuver around this to improve their lives. Leslie gave up her job simply the move back with her parents with no indication that she would be able to support herself until she got the job she wanted. It's important to keep a source on income while chasing down a dream job.
Hope this helps! :)
It's because every living cells do respiration. Respiration basically involves the oxidation of food(carbohydrate) to generate energy in form of ATP.
If a compound is made of one metal and one non-metal it's bond will be ionic, whereas if a compound is made of two non-metals, it's bond will be covalent.
C - Non-Metal
O - Non-Metal
CO = Covalent.
A) 0.875 M of MgBr2 is 0.875 mol/L
B) 23.7 mL = 0.0237 L
0.875 mol => 1 L
x mol => 0.0237 L
Cross multiply
1x = 0.875 × 0.0237
x = 0.0207 mol
>> In 23.7 mL of 0.875 M MgBr2 solution there is 0.0207 moles of MgBr2
C) Molar mass of MgBr2 (*) = 24.305 + (2 × 79.904) = 184.113 g/mol
184.113 g => 1 mol
x g => 0.0207 mol
Cross multiply
1x = 184.113 × 0.0207
x = 3.8111 g
>> 0.0207 moles of MgBr2 is equivalent to 3.81 g of MgBr2
>> In 23.7 mL of 0.875 M MgBr2 solution there is 3.81 g of MgBr2

Answer:Option (b) is the correct answer.
Explanation:
When a neutral element loses an electron then it acquires a positive charge and it is known as a cation.
For example, when a neutral iron atom loses three electrons then it forms a ion.
On the other hand, when a neutral element gains an electron then it acquires a negative charge and it is known as a anion.
For example, a sulfate ion means ion.
Thus, we can conclude that out of the given options sulfate is not a cation.
