Answer:
2.24 grams of CO2, assuming the reaction involves LiOH reacting with CO2.
Explanation:
0 grams, if you have a bottle of LiCO3 on the shelf.
Or should we assume we are reacting CO2 with a lithium compound?
We need to start with a balanced equation. That is why I added the perceptive, (but crass), remark of "get it from the shelf."
Here is one reaction that could be useful involving <em><u>lithium hydroxide</u></em>:
2LiOH + CO2 = Li2CO3 + H2O
This tells us that 1 mole of CO2 will produce 1 mole of Li2CO3. Lithium carbonate has a molar mass of 73.9 grams/mole. If we want 3.75 grams of the grimy stuff, we'll need (3.75g/73.9 g/mole) or 0.0508 moles of Li2CO3.
We'll need the same number of moles of CO2 to produce the Li2CO3, 0.0508 moles of CO2.
The molar mass of CO2 is 44 grams/mole. 0.0508 moles of CO2 is (0.0508 moles)*(44 grams/mole) = 2.24 grams of CO2.
If the reaction is different from the one I assumed here, do the same calculations using that balanced equation.
Balanced chemical reaction:
3K₂SO₄(aq) + Ca₃(PO₄)₂(s) → 2K₃PO₄(aq) + 3CaSO₄(s).
Ionic reaction:
6K⁺(aq) + 3SO₄²⁻(aq) + Ca₃(PO₄)₂(s) → 6K⁺(aq) + 2PO₄³⁻(aq) + 3CaSO₄(s).
Net ionic reaction: 3SO₄²⁻(aq) + Ca₃(PO₄)₂(s) → 2PO₄³⁻(aq) + 3CaSO₄(s).
aq(aqueous) means
dissolved in water.
s(solid) means that salt not dissolved in water.
This chemical reaction is double displacement
reaction - cations and anions of the two
reactants switch places and form two new compounds.
Temperatures in the central pacific ocean are warmer than usual and there is less rainfall. hope this helps! :)
In chemistry the need for standards when measuring quantities are in place for accurate measurement that is recognized world wide. This way, no matter what language people use, they will always understand there standards.
