Answer:
Molecular formula for the gas is: C₄H₁₀
Explanation:
Let's propose the Ideal Gases Law to determine the moles of gas, that contains 0.087 g
At STP → 1 atm and 273.15K
1 atm . 0.0336 L = n . 0.082 . 273.15 K
n = (1 atm . 0.0336 L) / (0.082 . 273.15 K)
n = 1.500 × 10⁻³ moles
Molar mass of gas = 0.087 g / 1.500 × 10⁻³ moles = 58 g/m
Now we propose rules of three:
If 0.580 g of gas has ____ 0.480 g of C _____ 0.100 g of C
58 g of gas (1mol) would have:
(58 g . 0.480) / 0.580 = 48 g of C
(58 g . 0.100) / 0.580 = 10 g of H
48 g of C / 12 g/mol = 4 mol
10 g of H / 1g/mol = 10 moles
Answer:
ionic
it is a mixture of a nonmetal and a metal which is what makes ionic compounds
covalent is a nonmetal and nonmetal
Explanation:
If reactants eventually collide,
there is an occurrence of reaction.

Therefore, when there is an increase concentration of
reactant, meaning to say that there are several moles of it every unit volume. An
example of this is a room having hundred of people will absolutely get higher
concentration compared to a room with one individual only.
Pertaining to effective collisions, if ever there is an
increase of concentration, the frequency and rate of effective collisions among
reactants surges in such a way that the rate of reaction also surges. Same with
passing into a room with only 1 individual compared to hundred people blind
persons, you probably want to proceed to the room with several people.</span>
<span>This is the simple logic
behind that scientific existence.</span>
