Answer:that sugar dissolves faster in a warm liquid than in a cool
Explanation:
Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher ... Diffusion of solvents,
Answer: The law of conservation of mass states that mass is neither created or destroyed, so the combined mass of all the products after the reaction will be the same as the mass of all the reactants and never more, but since the flask is not closed, the gases produced from the reaction will move into the atmosphere and the product left behind , the solids and/or liquids, will be the only products that you’ll end up weighing, meaning it’ll be less weight than the original reactants. The reason I’m interchanging weight and mass is because although weight changes with gravity, so long as the gravitational force stays constant throughout the experiment, it’s pretty much the same.
Explanation:
Answer:
Amount of heat required = 153.62 J
Explanation:
Given:
Mass = 163.45 g
∆Hvap = 43.3 kJ/mol
Molar mass C₂H₅OH = 46.07 g/mol
Find:
Amount of heat required
Computation:
Amount of heat required = Number of moles x Molar mass C₂H₅OH
Amount of heat required = [163.45/46.07][43.3]
Amount of heat required = 153.62 J
Answer:
The correct option is;
b.Chemical bond
Explanation:
Chemical bonds are the attractive forces holding the atoms within a compound together. The concept of chemical bonding is fundamental to the explanation of chemical phenomena including reaction mechanism and molecular behavior
There are different chemical bonds such as ionic bonds formed by the attraction of oppositely charged ions, covalent bonds, formed by the sharing of electrons and polar covalent bonds.
