CaCl₂ (aq) + K₂CO₃ (aq) → CaCO₃ (s) + 2 KCl (aq)
where:
(aq) - aqueous
(s) - solid
Explanation:
Calcium chloride (CaCl₂) will react with potassium carbonate (K₂CO₃) to produce solid calcium carbonate (CaCO₃) and potassium chloride (KCl).

Answer:
It is called the jet stream.
Answer:
False
Explanation:
Glucose is a monosachharide carbohydrate, with the molecular formula C₆H₁₂O₆.
Glucose molecule can exist in two forms-
1. Open chain form
2. cyclic form
The open chain form of the glucose is an unbranched 6 carbon atom chain. The carbon 1 of the molecule is an aldehyde group and the rest of the five carbon atoms have one hydroxyl group each.
The cyclic form of the glucose can be-
a. Pyranose: The pyranose form is a 6-membered cyclic ring, which consists of 5 carbon atoms and 1 oxygen atom in the ring.
b. Furanose: The furanose form is a 5- membered cyclic ring, which consists of 4 carbon atoms and 1 oxygen atom in the ring.
In an aqueous solution, 99% glucose molecule exists in the cyclic pyranose form as it is energetically more stable.
Therefore, in aqueous solution, the glucose molecule does not prefer the open-chain conformation.
Therefore, the statement is false.
