Answer:
8.58 g/cm3
Explanation:
density = mass / volume
be attention that the question gives u the length of
one side of the cube so u should calculate the volume
of the cube using your information of math .
1st we calculate the volume of the cube :
V of cube = a 3= axaxa
= 0.250 x0.250 x0.250
= 0.0156 cm3
2nd step
density = mass/volume
= 0.134/ 0.0156 = 8.58 g/cm3
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
The elements combine with other elements in order to complete their octet and attain stability. The combination can take place either by transfer of electrons or by sharing of electrons. The sharing of electrons results in formation of covalent bond whereas transfer of electrons results in the formation of ionic bonds. The loss of electrons will result in the formation of cation whereas the gain of electrons results in formation of anion. The two oppositely charged ions are held together by electrostatic force of attraction between them.
Hence, an ionic is a force that holds two oppositely charged ions together.
