I think it’s C since the ice changes from solid to a liquid which is physical and then it reacts with calcium metal making the calcium hydroxide which is chemical change. And another sign of it being chemical was the release of gas.
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.
The chemical formula C₂H₆O, which is designated as option D, is equivalent to this structural formula.
<h3><u>What is a Chemical Formula ?</u></h3>
Chemical element symbols, numbers, and occasionally additional symbols like parentheses, dashes, brackets, commas, and plus (+) and minus () signs are used in a chemical formula to represent information about the chemical proportions of the atoms that make up a certain chemical compound or molecule.
- An empirical formula represents by symbols, such as Na for sodium and Cl for chlorine, with subscripts that show the relative number of atoms in each.
- The composition of any member of an entire class of compounds can be represented by a general formula, a sort of empirical formula.
