The answer is low frequency and long wavelength
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:
1/10 or 0.1
Explanation:
Quantities at which equivalence can be obtained are:
95, 96, 97, 98, 99, 100, 101, 102, 103, 104
Number of quantities = N = 10
Probability that the equivalency is obtained exactly at 100 mL can be calculated as follows:
P(X = 100) = (Number of favourable outcomes) / (Total Number of Outcomes)
P(X = 100) = 1/10
P(X = 100) = 0.1
Answer:-
2.0 L
Explanation:-
Initial Volume = V 1 = 3.0 L
Initial Pressure P 1 = 4.0 atm
New pressure P 2 = 6.0 atm
Using boyle's law
P1 V1 = P2 V2
New Volume V2 = P1 V1 / P2
= 4.0 atm x 3.0 L / 6.0 atm
= 2 .0 L
