I would i have think it is either a) east or c) west b/c couldn’t go by it self
Answer:
The correct option is: 2.50 g
Explanation:
Reaction involved: Mg(s) + 2 HCl(aq) → MgCl₂(aq) + H₂(g)
Molar mass: Mg = 24.305 g/mol, HCl = 36.461 g/mol
In the given reaction, 1 mole Mg reacts with 2 moles HCl.
Given: mass of HCl = 7.50 g
So, the number of moles of HCl = given mass ÷ molar mass = 7.50 g ÷ 36.461 g/mol = 0.2057 moles
Therefore, the<u> number of moles of Mg</u> that reacts with 0.2057 mole HCl = 0.2057 ÷ 2 = 0.1028 moles
Therefore, <u>the mass of Mg in grams</u> = molar mass × number of moles = 24.305 g/mol × 0.1028 mole = 2.5 g
Answer: C) Heat
What I know so far is that heat makes it harder for the electrons to reach the source, thus making it hard to collide with the nucleus, but I’m not sure so you can see if it’s correct.
<span>Ethane reacts with oxygen to yield carbon dioxide and liquid water. I believe the correct answer from the choices listed above is option B. The correct equation for this reaction would be as follows:
