Explanation:
Answer:
The answer to your question is: mass = 0.760 g
Explanation:
Data
V = 0.285 L
T = 57°C = 330°K
P = 1 atm
R = 0.082 atm L/mol°K
mass = ?
Formula
PV = nRT
n = PV / RT
Substitution
n = (1)(0.285) / (0.082)(330)
n = 0.285 / 27.06
n = 0.011
mW Pentane = (12 x 5) + (12 x 1) = 72 g
72 g of pentane ----------------- 1 mol
x ----------------- 0.0105 mol
x = (0,0105 x 72) / 1
x = 0.756 g ≈ 0.760 g
Answer:
nonmetal
Explanation:
In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
(3) empirical, molecular, structural is the correct answer.
Group (1) shows the little factors to form substances and compounds. Group (2) shows the types of elements. Group (4) shows the types of chemical reaction.
