I think it is c I'm only in 7th grade but I'm pretty sure that the answer is c
I believe it’s false, I think I had this before
2Na⁺ + CO₃²⁻ -> Na₂CO₃- the molecular formula for sodium carbonate
Ca²⁺ + 2NO₃⁻ -->Ca(NO₃)₂ - formula for calcium nitrate -
Ca²⁺ + CO₃²⁻ --> CaCO₃ - it forms calcium carbonate with formula
Na⁺ + NO₃⁻ -->NaNO₃ -formula for sodium nitrate -
the balanced chemical equation for the reaction is;
Na₂CO₃(aq) + Ca(NO₃)₂(aq) --> CaCO₃(s) + 2NaNO₃(aq)
correct answer is 4
Explanation:
The asked in the Question is missing, although i am assuming the number
as ÷.
The given expression contains an irrational number. So, the quotient will also be an irrational number.
Solving
Which is an irrational number.
