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
Nitrogen (like70ish % and oxygen like 20%)
Answer:
A 26m
Explanation:
firstly the answer will not be part c as distance unit will be meters (m)
next, substitute the values of a and t as shown
the answer rounded off to 2 significant figures will be hence 26m
The answer is the last option
Explanation:
Escape velocity is the minimum velocity required for an object to come out of the gravity of earth or any planet !
for earth , it is 11.2 km/sec
