What is Metallic bond ?
- Metallic bond is a force that holds atoms together in a metallic substance.
Explanation:
Molar mass of Hg = 200.59g/mol.
Therefore Moles = Mass / Molar mass
= 100g / (200.59g/mol) = 0.499mol.
Mass of CO₂ = 33 g
<h3>Further explanation </h3>
Complete combustion of Hydrocarbons with Oxygen will be obtained by CO₂ and H₂O compounds.
If O₂ is insufficient there will be incomplete combustion produced by CO and H and O
Reaction
CH₄ + 2O₂⇒CO₂ + 2H₂O
mol CH₄ :
mol O₂ :
A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients
Because O₂ ratio smaller then O₂ becomes the limiting reactants
So mol CO₂ from limiting reactants
mol CO₂ :
mass CO₂ :
Answer: 400° kelvin
Explanation:
400° k translates to about 260° fahrenheit, and 260 > 100!
just ask if you need it in celsius :3
Answer:
a) The metal with the higher heat capacity.
Explanation:
The heat (Q) absorbed by a metal can be calculated using the following expression.
Q = c × m × ΔT
where,
c is the specific heat capacity of the metal
m is the mass of the metal
ΔT is the change in the temperature
Q = c × m × ΔT
ΔT = Q/ c × m
Considering both metals have equal mass (m) and are subject to the same amount of heat (Q), the change in the temperature is inversely proportional to the specific heat capacity. The metal with the higher specific heat capacity will undergo the smallest change in temperature.
