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
Answer:
The answer is "Choice B and Choice C".
Explanation:
In this question, the two features, which make electromagnetic waves effective for interaction, which they don't really need a method of travel of data and move information quite fast. The motion among magnetic and electrical forces is generated by electromagnetic radiation. These waves will spread without the need for a source for their movement, and they have high speed and also the electromagnetic waves it has the same frequency as light.
B. The sound of the engine will get louder and the pitch higher.
