<span>When c2h4 molecules polymerize, the name of the polymer formed is (b) Polyethylene. This is because the compound C2H4 is ethylene (common name) or ethene (IUPAC name) and polymerizing it would produce polyethylene. The other names are not applicable for C2H4.

Well, if you have a light bulb (turned on) n u put a little gulf ball in front of it it will make a shadow.
In this case the light bulb is the Sun and the gulf ball is the Moon.
So the Moon causes the shadow because it covers the light.
I really hope my explanation helps you out!

Answer:
See explanation
Explanation:
The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another. Hence, chemical energy in a battery can be converted to electrical energy.
Usually, the conversion of energy from one form to another is not 100% efficient according to the second law of thermodynamics. Some energy is wasted in the process, sometimes as heat.
Hence, in an ideal situation where no heat energy is produced; all the chemical energy is converted to electrical energy (100% energy conversion). There will be no energy loss if no heat is produced.
Answer:
0.238 M
Explanation:
A 17.00 mL sample of the dilute solution was found to contain 0.220 M ClO₃⁻(aq). The concentration is an intensive property, so the concentration in the 52.00 mL is also 0.220 M ClO₃⁻(aq). We can find the initial concentration of ClO₃⁻ using the dilution rule.
C₁.V₁ = C₂.V₂
C₁ × 24.00 mL = 0.220 M × 52.00 mL
C₁ = 0.477 M
The concentration of Pb(ClO₃)₂ is:
