Answer:
2) Copper (II) Chloride
Explanation:
A precipitate will form if the resulting compound is insoluble in water. For example, a silver nitrate solution (AgNO3) is mixed with a solution of magnesium bromide (MgBr2).
Hello!
To answer this question you need to first write the chemical equation for this reaction:
2Na(s) + Cl₂ → 2NaCl
Now, you know that to react 1 mol of Chlorine gas you'll need 2 moles of sodium, this can be written as follows:
(1)So, the last step in solving this problem is to know how many moles of Chlorine you have. For that, you'll use the Ideal Gas Law which states that:
(2)Where P is pressure, V is volume, n is the amount of the gas in moles, R is the Constant of the Ideal Gases and T is the temperature.
The final step is replacing the expression
(2) in
(1) and you're good to go!
I won't give the answer to this problem, just leave the equation for you to replace the values.
Answer:
The only limiting reactant is the magnesium.
Explanation:
According to the 2 reactions that occur, oxygen intervenes in both.
2 Mg + O2 -----> 2 MgO + energy
CH4 + 2 O2 ------> CO2 + 2 H2O
Magnesium is the only limiting reagent in both reactions since it is the only one that is completely consumed, and as can be seen in the chemical reaction, 2 moles of magnesium and only 1 mole of oxygen are needed to react.
