Do elements in a group on the periodic table have similar chemical properties because their atoms have the same number of electrons
A. same number of outermost electrons
Explanation:
Ethanol is made by the hydration of ethylene in the presence of a catalyst such as sulfuric acid (H 2SO 4).
Answer:
1837 electrons.
Explanation:
1837 electrons have the same mass as 1 proton.
Answer:
4C₈H₄OH + 35O₂ → 32CO₂ + 10H₂O
Explanation:
The unbalanced reaction expression is given as:
C₈H₄OH + O₂ → CO₂ + H₂O
To solve this problem, we use a mathematical approach.
aC₈H₄OH + bO₂ → cCO₂ + dH₂O
Conserving C: 8a = c
H: 5a = 2d
O: a + 2b = 2c + d
Let a = 1, c = 8, d =
, b = 35
4C₈H₄OH + 35O₂ → 32CO₂ + 10H₂O
Two properties of a star is luminosity and temperature.
