Answer:
200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.
Explanation:
Mass of solution = M
Mass percentage of the solution of lime = 15%
Mass of lime or calcium hydroxide = m = 30 g
The Formula of mass percentage is given as :
On substituting the values in ab above formula :
200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.
Answer is (b)
2,3,1 is the stoichiometry
The values in front of the elements are the stoichiometric values
(Since Al2Br6 has no value in front, it's considered 1)
Kinetic energy is energy in motion. Which of these isn't in motion?
A lady walking slowly but surely down a street is moving, right? So that isn't right.
A hockey puck sliding on ice has motion.
A man running around a track definitely demonstrates kinetic energy.
But, a baseball glove doesn't. Maybe if it's moving on someone's hand, but by itself, it isn't moving.
With the increase in temperature, the state of matter of water will changed.
<h3>What happen if the temperature of the system is increased?</h3>
If the temperature of water is increased then the state of matter will change from liquid state to gaseous state because the temperature break down the bonds that is present between two water molecules.
So we can conclude that with the increase in temperature, the state of matter of water will changed.
