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:
Stars and gas in the galactic disk moves in a roughly circular path about the center of the galaxy
Answer:
9830 J
Explanation:
(Just a tip, you should use the degree symbol ° instead of *)
That being said we know W = F*d*cos(θ). In this case θ = 35°.
W = F*d*cos(θ) = 600*20*cos(35)
= 12000*cos(35)
= 9829.925 Joules
Solution: Work ≈ 9830 J
