Dalton postulated that atoms of the same elements had the same mass while atoms of different elements had different masses.
The discovery of isotopes revealed that atoms of the same element did not necessarily have same masses, they could have different masses.
Therefore, the modern periodic table that we use nowadays contains the average atomic mass of all the isotopes found for a given element.
The carbon dioxide and water are formed, for example:
CH₄ + 2O₂ = CO₂ + 2H₂O
methane
2C₂H₆ + 7O₂ = 4CO₂ + 6H₂O
ethane
C₃H₈ + 5O₂ = 3CO₂ + 4H₂O
propane
We can relate the mass to the number of moles by using the compound's molar mass as a direct conversion factor
Answer:
b cation
Explanation:
that plus means it is positively charged. ions that are positively charged are cations. negatively charged ions are called anions
Answer:
The correct option is;
(b) 0.8 Tm
Explanation:
Sintering is a form of heat treatment given to introduce a material in powdery form in order to introduce the properties of integrity and strength
by the application of heat to the powder at a temperature below its melting point.
With regards to imparting favorable metal properties in the metal to undergo sintering such as ductility, toughness, porosity, hardness, strength it is required to select a sintering temperature higher than 0.6 - 0.8 Tm.
