Answer:
Explanation:
Hydrocarbon:
a = An organic compound made up of only carbon and hydrogen.
Such as alkane, alkene, alkyne.
Cyclic hydrocarbon:
c = Carbon chain that form rings.
Such as benzene, cyclo heptane etc
Isomers:
d = Compounds with same molecular formula and different structural formula.
Alkanes:
e = refers to saturated hydrocarbons, no matter the shape
such as methane, ethane, propane etc.
Alkene:
f = Any hydrocarbon that have at lest one carbon carbon double bond.
such as ethene, propene, butene
Saturated hydrocarbons:
b = Carbon atoms are saturated with so many hydrogen atoms that no more bonds may be formed
such alkanes.
Answer:
1) The power of Niagara Falls is 1.176 × 10⁹ W
2) The number of 15 W LED light bulbs it could power is 78.4 × 10⁶ light bulbs
Explanation:
1) The Niagara falls water mass flow rate = 2,400,000 kg/s
The height of the fall = 50 meters
The gravitational potential energy = Mass (kg) × height (m) × gravity (9.8 m/s²)
The power = The energy converted per second = Mass flow rate (kg/s) × height (m) × gravity (9.8 m/s²)
Therefore;
The power of Niagara Falls= 2,400,000 kg/s × 50 m ×9.8 m/s²= 1.176 × 10⁹ W
The power of Niagara Falls = 1.176 × 10⁹ W
2) The number, n, of 15 W LED light bulbs it could power is given by the relation;
n × 15 W = 1.176 × 10⁹ W
∴ n = 1.176 × 10⁹ W/(15 W) = 78.4 × 10⁶ light bulbs
The number of 15 W LED light bulbs it could power = 78.4 × 10⁶ light bulbs.
Answer:
3
Explanation:
Atoms are made of 3 parts.
- The protons and Neutrons form together creating a sun, or nucleus at the center
- The electrons orbit this sun like planets.
The element with Th is Thorium. It is a metallic chemical element that when exposed to air, hardens.
