Given the mass of CO2 =15.02 g
Moles of 
=
Mass of H2O = 2.458 g
Moles of 
=
Moles of C = 
Moles of H = 
Mass of C in the sample = 
Mass of H = 
=0.275 gH
Mass of O in the sample = 5.467 g - (4.095 g +0.275 g) = 1.097 g O
Moles of O = 
Simplest mole ratios of the elements in the compound:
Therefore the empirical formula of the compound is 
Answer:
The sun.
Explanation:
It is closer to Earth, therefore bigger to us, and not just a small point of light.
Answer:
Hello There!
Explanation: Your Answer will be, D) conduct electricity in water.
Both acids and bases conducts electricity and water.
When acid dissolves in water, they are good electrolytes.
When bases dissolves in water they are good electrolytes.
Electrolytes are liquid or molten substances that are able to conduct electricity.
they conduct electricity by the use of their ions in solution.
Since acid and bases ionize in solution, they will conduct electricity.
An acid is a substance that produces excess hydroxonium ion in solution.
A base produces excess hydroxyl ions in solution. Hope This Helps!
Answer:
The volume of gold is 3.3 cm³.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m³.
Other units are given below,
g/cm³, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Mass of gold = 63 g
Density of gold = 19.32 g/cm³
Volume of gold = ?
Solution:
d = m/v
v = m/d
v = 63 g/ 19.32 g/cm³
v = 3.3 cm³.
