Nuclear fission is used enable to release energy in power plants. The constant collision of particles within the reactor, create most of the plants energy.
Answer: Option (b) is the correct answer.
Explanation:
State of a substance changes when heat is provided to a substance.
This is because when we heat water then intermoleclar forces present within its molecules tend to break down. Due to this molecules start to move away from each other.
As a result, kinetic energy of molecules increases and they collide rapidly. Hence, solid state of water changes into liquid state and upon excessive heating liquid state of water changes into vapor state.
Thus, we conclude that temperature of water needs to change in order to change its state of matter.
Answer:
an alkali
Explanation:
an alkali is a base that is slightly soluble in water
Answer:
7.5 moles of CaBr2 are produced
Explanation:
Based on the equation:
2AlBr3 + 3CaO → Al2O3 + 3CaBr2
<em>2 moles of AlBr3 produce 3 moles of CaBr2 if CaO is in excess.</em>
<em />
Using this ratio: 2 moles AlBr3 / 3 moles CaBr2. 5 moles of AlBr3 produce:
5 moles AlBr3 * (3 moles CaBr2 / 2 moles AlBr3) =
<h3>7.5 moles of CaBr2 are produced</h3>

1. 
Explanation:
2. <em>Seismic</em> <em>waves</em> vibrate from side to
side and up and down. They go through solids only, travel slower than <em>Pressure</em> [or <em>Primary</em>] <em>waves</em>, which arrive second, and shake the ground violently.
1. A <em>Ritcher</em><em> </em><em>scale</em><em> </em>senses the magnitude of earthquakes.
