Answer:
<em>»</em><em> </em><em>λ </em><em>=</em><em> </em><em>0</em><em>.</em><em>0</em><em>2</em><em>m</em>
Explanation:
Given :
Velocity of the wave {v}= 12 m/s
Frequency {f} = 600 Hz
Apply Wavelength formula :
• 
→ λ = 
→ λ = 
→ λ = 0.02m

Answer:
carbon dioxide
Explanation:
Carbon burns in oxygen to form carbon dioxide. Since hydrocarbon fuels only contain two elements, we always obtain the same two products when they burn. In the equation below methane (CH 4) is being burned. The oxygen will combine with the carbon and the hydrogen in the methane molecule to produce carbon dioxide (CO 2) and water (H 2O).
Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide), CO2. ... When the air or oxygen supply is restricted, incomplete combustion to carbon monoxide, CO, occurs. 2C(s) + O2(g) → 2CO(g) This reaction is important. When one mole of carbon is exposed to some energy in the presence of one mole of oxygen gas, one mole of carbon dioxide gas is produced. This reaction is a combustion reaction.
Answer:
Compounds are pure substance consisting of two or more different atoms
Explanation:
The electrons in the outermost shell of an atom are the valence electrons. These electrons are the most loosely held in an atom.
The energy required to remove these electrons are not as great as those of the inner shell electrons.
- Atoms of some elements show no tendency to combine with other atoms because they have completely filled outer energy levels.
- Their outermost shell, valence shell and the electron numbers are complete for them. These are the noble gases.
- other atoms share or exchange their valence electrons in order to have a stable configuration.
- The valence electrons are involve in inter-atomic bond formation and interactions
- Also the distribution of these electrons determines inter-molecular interactions between molecules.
