Answer:
Mass of solid = 189.141 gram
Explanation:
Given:
Total volume = 93 ml
Mass of liquid = 33.7 gram
Density of liquid = 0.865 g/ml
Density of solid = 3.50 g/ml
Find:
Mass of solid = ?
Computation:
Volume of liquid = Mass of liquid / Density of liquid
Volume of liquid = 33.7 / 0.865
Volume of liquid = 38.9595 ml
Volume of solid = Total volume - Volume of liquid
Volume of solid = 93 - 38.9595
Volume of solid = 54.0405 ml
Mass of solid = Volume of solid × Density of solid
Mass of solid = 54.0405 ml × 3.50 g/ml
Mass of solid = 189.141 gram
Answer:
-OOH
Explanation:
This forms an acid if it comes in contact with a metal
The acid yields H+ ions while the base yields OH- ions
Yes you balanced it correctly : CH₃CH₂CH₃ ₍g₎ + 5O₂ ₍g₎ -------> 3CO₂ ₍g₎ + 4H₂O ₍g₎
A hack to checking if its correct when they give you the structural formula of one of the species (CH₃CH₂CH₃) is to convert it to the molecular formula and if you get the same answer then it's correct.
So CH₃CH₂CH₃ is the struct-formula for the molec-formula C₃H₈
C₃H₈ + 5O₂ --------> 3 CO₂ + 4H₂O (which means your correct =D)
Answer:
C2H4 + 3O2 --> 2CO2 + 2H2O
Explanation:
For an equation to be balanced, it must have an equal number of atoms on each side. C2H4 + 3O2 --> 2CO2 + 2H2O is the only equation out of these four the fulfills this requirement.
