The water in Glass A is cooler than the water in Glass B; therefore, the particles in Glass A move slower.
Option D
<h3>Chemical Reactions</h3>
Generally,the experiment shows that glass B temperature is higher than glass temperature A and this is given that observation that the solute dissolves faster in glass B than glass A.
Therefore,The water in Glass A is cooler than the water in Glass B; therefore, the particles in Glass A move slower.

1 W is equivalent to 1 J/s
So,
0.5 Wh = 0.5 (J/s) (h)
Converting h to s,
0.5 (J/s) (h) (60min/1h) (60s/1min) = 1800J
Thefore,
0.5Wh is 1800J or 1.8kJ of heat energy
Explanation:
Divide 67.6% by 201 of mercury
Divide 10.8% by 32 of sulfur
Divide 21.6% by 16 of oxygen
Then divide number by itself .
Example : Divide 2.97 by both sulfer moles and oxygen moles . Multiply by 2 to get whole number
The phenomenon is known as the Greenhouse Effect.
When the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere. The phenomenon is known as the Greenhouse Effect.
Answer:
Atomic number = 25 protons
Mass number = ( 25 + 30 ) = 55
