Answer:
it natural gas or fossil fuels
Answer:
1.15 g/mL
Explanation:
The following data were obtained from the question:
Mass (m) = 55.6 g
Volume (V) = 48.5 mL
Density (D) =?
Density is simply defined as the mass of the substance per unit volume of the substance. It is represented mathematically as:
Density (D) = mass (m) /volume (V)
D = m/V
With the above formula, we can obtain the density of the object as follow:
Mass (m) = 55.6 g
Volume (V) = 48.5 mL
Density (D) =?
D = m/V
D = 55.6/48.5
D = 1.15 g/mL
Therefore, the density of the object is 1.15 g/mL
Answer:
An increase in temperature indicates that the molecules of gas speed up.
Explanation:
The molecular kinetic theory states that the average kinetic energy of gas particles (molecules) is proportional to the absolute (Kelvin) temperature of the gas, and all gases at the same temperature have the same average kinetic energy.
Therefore, as the temperature increases so the kinetic energy increases.
It is also known that the kinetic energy is proportional to the squared speed of the particles, therefore the higher the kinetic energy the average speed of the molecules:
- higher temperature → higher kinetic energy → higher average speed
Mass of carbon monoxide : 0.95 g
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂
MW Fe₂O₃ : 159,69 g/mol
mol Fe₂O₃ :
mol ratio Fe₂O₃ : CO = 1 : 3, so mol CO :
mass CO (MW = 28,01 g/mol) :
