Answer:
Total number of water molecules produced after the reaction is 1.956×10^22 molecules of water.
Explanation:
By the reaction
H2+ 1/2 O2 → H2O
Moles of O2 = 5.2\32
⇒1 mole of O2 produce 1 mole of H2O
1 mole O2 will produce 2 mole of H2O
Therefore, 5.2\32 mole will produce 
⇒ Molecules of H2O will be
= 
= 1.956×10^22 moleculesof H2O.
Answer:
in a sold the particles are in a fixed position and can only vibrate on the spot but when it changes into a liquid the energy is used to weaken the bonds so there are weak forces of attraction between the particles, all particles are still touching each other but are now free to move around. Ina gas all the bonds are broken, the gas particles are free to move around anywhere and the more collisions there are, the more the pressure increases
There are only two possible structures for an octahedral
molecule with a formula of ax4y2. One is when the two y’s are next to each
other and the other one is when the two y’s are of the opposite side of the molecule.
Different structures can be drawn but only two types of molecule can be formed.
CS₂ + Cl₂<span> </span>→ CCl₄ + S₂Cl₂<span> [unbalanced equation]
</span>CS₂ + 3Cl₂ → CCl₄ + S₂Cl₂ [balanced equation]
∴ the mole ratio of Cl₂ : CCl₄ is 3 : 1 (option D)
Thermal energy can be converted into heat energy. Or thermal energy of steam can be converted to mechanical energy in the turbine.
LED (light-emitting diode) can also convert heat into light.
