Answer:
They all end up in the oceon
Explanation:
Answer:
A. Ba(NO₃)₂(aq) + Na₂CO₃(aq)
Explanation:
- The reaction between aqueous Ba(NO₃)₂ and Na₂CO₃ is a precipitation reaction.
- The complete equation for the reaction is;
Ba(NO₃)₂(aq) + Na₂CO₃(aq) → BaCO₃(s) + NaNO₃(aq)
- Barium carbonate is the precipitate formed during the reaction.
- All nitrates are soluble in water and all salts of sodium are soluble in water, therefore, Ba(NO₃)₂, Na₂CO3, and NaNO₃ are soluble in water.
- Precipitation reaction involves reaction of soluble salts to form a precipitate as one of the product.
Answer:
<h3>The answer is 8.98 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of cube = 150 g
volume = 16.7 cm³
We have
We have the final answer as
<h3>8.98 g/cm³</h3>
