If a molecule has four hybrid sp3 orbitals, it can be concluded that the molecule has a TETRAHEDRAL GEOMETORY
When a gas is heated in a sealed container, the gas particles move faster and hit the sides of the container with more force leading to an increase in the pressure of the gas.
An increase in the temperature of a gas increases the collision rate of the molecules of the gas according to the kinetic theory.
With increased kinetic energy, the molecules of the gases collide more frequently with each other and the walls of the container.
The collision creates an increase in the magnitude of pressure inside the container.

NaOH
Na=23
O=16
H=1
SO,NaOH=23+16+1
NaOH=40g/mol
42% of 40=42/100x40
oxygen is the compound
density=mass/volume
1.30=mass/6
mass=7.8g
Answer:
168.56 mL
Explanation:
density = mass/volume, use basic algebra skills to replace the volume and solve
a. chain reaction
Explanation:
In a fission, a chain reaction is one where a neutron embeds itself in the nucleus of an U-235 atom and causes it to break apart. After this, more neutrons are created. The neutrons carry on the cycle by starting the fission process over and over again.
Chain reactions typifies most nuclear reactions taking place in the nucleus of an atom.
They are repeated loops that takes place until an atom reaches it state of stability.
- They are not exclusive to fission reactions alone.
- Chain reactions also takes place during nuclear fusion
- In fusion two atoms combines to produce a single nuclide.
- The steps goes on and on
- This why the sun keeps burning and bursting with energy
