Answer:
2moles of H2
Explanation:
First, let us generate a balanced equation for the reaction between calcium and water. This is illustrated below:
Ca + 2H20 —> Ca(OH)2 + H2
From the equation,
2moles of H2O produced 1mole of H2.
Therefore 4moles of H2O will produce = 4/2 = 2moles of H2.
Answer:
36000 centimeters
Explanation:
If the average speed of a species of tortoise is 0.36 km/h, then it would be 36000 centimeters.
The change in the arrangement of particles as heat energy and temperature increase because of the increase in the kinetic energy of the particles.
Kinetic energy of any atom is calculated as:
K.E. = 1/2(mv²), where
v = velocity and m = mass
So, when we apply heat energy or increase the temperature of any system then the energy of the constitute particles is also increases which results in the increase of the average kinetic energy of the particle. Due to this kinetic energy particle will move with high velocity and disturbs the arrangement of the system.
Hence, due to increase in average kinetic energy, arrangement of the particles changes.
