Answer:
x is CO2
y is H2O
Explanation:
An organic compound that contains carbon and hydrogen is called a hydrocarbon.
When a hydrocarbon is burnt in air (combustion) only two products are obtained; carbon dioxide and water. The carbon dioxide comes from the carbon component of the molecule while the water comes from the hydrogen component of the molecule.
Therefore, for a hydrocarbon CxHy we obtain; xCO2 and (x + 1)H2O as products.
Answer:
Explanation: Rutherford model, also called Rutherford atomic model, nuclear atom, or planetary model of the atom, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford. The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun. Hope that helps!
Hydrogen burns with oxygen as in combustion reaction to form water.
H₂ + O₂ → H₂O
Answer:
d
Explanation:
Valence electrons are in the outermost shell. They form chemical bonds with other elements, not any other electrons. Hope this helps!
