Answer:
The correct option is (a).
Explanation:
We need to find the product of given numbers.
First number = 29.5
Second number = 240
Product of two numbers = 29.5 × 240
=
Zeroes from numerator and denominator get cancelled.
So,
Hence, the correct option is (a).
Answer: BaCO3(s) + 2H+(aq) --> Ba+2 + H2O(l) + CO2(g)
Explanation: Net ionic equations show only the species or atoms that participate in the reaction, in this case gas-forming
When solid barium carbonate is combined with excess aqueous hydroiodic acid the reaction that take place is.
BaCO3(s) + 2HI(aq) --> BaI2 (aq) + H2O(l) + CO2(g)
To write a ionic equation is necesary to separte the species that are dissociated in water (ag) and expresed it as ions showing the charge
BaCO3(s) + 2I-(aq) + 2H+(aq) --> Ba+2 + 2I- (aq) + H2O(l) + CO2(g)
Since I- is present in both sides of the reaction, it's eliminated in the net ionic equation, and the final expression is:
BaCO3(s) + 2H+(aq) --> Ba+2 + H2O(l) + CO2(g)

Answer:
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.
Explanation:
They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.
