Answer: The answer is D.
Explanation: The warm water will cause the sugar to dissolve quicker.
Answer:
A
Explanation:
Element A has 3 electrons in outermost shell so its valency is 3. It will loose 3 electrons to attain stability, as loss of 3 electrons is easier than gain of 5 electrons.
Valency of B is −2 as it will gain 2 electrons to attain stability and combine with other atom.
Valency of A⟶+3
Valency of B⟶−2
(Refer to Image)
Cross multiply valency of A and B
∴A2B3 compound will be formed.
A high - energy state of matter made up of a swirling, ionized gas
Halite crystal is growing and can attach very quickly and eventually form a smooth, stable faces where new atoms can easily attach themselves.
The mass of KCl that exists in 20.3 g of solution containing 1.14% by mass of KCl is 0.23 g
From the question given above, the following data were obtained:
Mass of solution = 20.3 g
Percentage of KCl = 1.14% = 1.14 / 100 = 0.0114
<h3>Mass of
KCl =?</h3>
Cross multiply
Mass of KCl = 0.0114 × 20.3
<h3>Mass of KCl = 0.23 g</h3>
Therefore, the mass of KCl in the solution is 0.23 g
