I agree with Omar because it depends on what the charge of the object and magnet is. If the magnet is negative and the object is positive, they will pull together. If the magnet is negative and the object is negative then they will pull apart.
Explanation:
Aqueous hydrochloric acid HCl will react with solid sodium hydroxide NaOH to produce aqueous sodium chloride NaCl and liquid water H2O. Suppose 15.7 g of hydrochloric acid is mixed with 27. g of sodium hydroxide. Calculate the maximum mass of sodium chloride that could be produced by the chemical reaction.
Answer:
25.155 gram
Explanation:
HCl(aq.) + NaOH(aq.) ⇒ NaCl + H2O
According the above equation equal number of moles of reactant are producing same number of moles of products.
Now, no. mole of HCl = 15.7/(1+35.5) = 0.43 moles
no. of moles of NaOH = 27/(23+16+1) = 0.675 moles
Since the amount of sodium hydroxide exceeds the amount of hydrochloric acid, the maximum amount of each substance participating in the reaction is HClν ν 0.43 moles .Therefore, the maximum amount of NaCl that can be produced is as follow
= (23+35.5)×0.43 = 25.155 gram

Consider the Fischer ester synthesis of methyl benzoate from benzoic acid and methanol in the presence of sulfuric acid as a catalyst. A reaction was performed in which 3.8 g of benzoic acid was reacted with excess methanol to make 2.0 g of methyl benzoate. Calculate the theoretical yield and percent yield for this reaction.
Answer:
48.8%
Explanation:
The reaction has a 1:1 mole ratio so;
Number of moles of benzoic acid reacted = mass/molar mass = 3.8 g/122.12 g/mol = 0.03 moles
So;
0.03 moles of methyl benzoate is formed in the reaction
Mass of methyl benzoate formed = 0.03 moles * 136.15 g/mol = 4.1 g
percent yield = actual yield/theoretical yield * 100/1
percent yield = 2.0 g/4.1 g * 100 = 48.8%

What is the percent yield of LiCl if I produced 30.85g LiCl and my theoretical yield was calculated to be 35.40g LiCl?
Answer:
87.15%
Explanation:
To find percent yield, we can use this simple equation
[tex]\frac{Actual}{Theoretical} *100[/tex]
Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.
They give us these values, so to find the percent yield, just plug the numbers in.
[tex]\frac{30.85}{35.40} *100\\\\ =87.15[/tex]
So, the percent yield is 87.15%
An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.

Hydrazine (N2H4) and dinitrogen tetroxide (N2O4) form a self-igniting mixture that has been used as a rocket propellant. The reaction products are N2 and H2O. Part A Write a balanced chemical equation for this reaction. Express your answer as a chemical equation. nothing A chemical reaction does not occur for this question. Request Answer Part B What is being oxidized, and what is being reduced
Answer:
2N₂H₄+N₂O₄→3N₂+4H₂O; N₂H₄ gets oxidized, N₂O₄ gets reduced.
Explanation:
Part AThey tell us what substances react to form what products, so we can write an unbalanced chemical equation from those substances.
N₂H₄+N₂O₄→N₂+H₂O
To balance this equation, we need to make it so there is an even amount of each element on both sides of the reaction. We can do this by multiplying the amount of each substance by adding a coefficient in front of it.
2N₂H₄+N₂O₄→3N₂+4H₂O
Part BTo identify what is being oxidized and what is being reduced, look at the oxidation charges of each element.
N₂H₄ gets oxidized, N₂O₄ gets reduced.
