Explanation:
The flemish are an ethnic group which belong to the northern part of Belgium called Flanders. They also speak a language called flemish. The major population of Belgium are the flemish. The language they speak is a Low Franconian dialect cluster of the Dutch language.
There was a country called the flanders located in the lowlands of Europe. Any person from this country was considered as flemish previously.
Answer:
The pressure increases on all surfaces of the container. It begins to heat up. And depending on the strength of the container, it may just break.
Explanation:
Your body now has a static charge. When you touch the metal knob, electrons suddenly move from your body through your fingertips to the metal doorknob as a static discharge.
When the materials are heated they undergo a chemical change. The reaction is non reversible. The sugar, flour and eggs can no longer be separated. The properties of the materials have changed so it is a chemical change.
Answer:
a. The reaction associated with DHºf for an ionic compound
Explanation:
An exothermic process is a process that loses heat for the surroundings, so the temperature of the system must decrease, and ΔH must be negative.
DHºf or ΔHºf of an ionic compound is always negative because the final energy is always lower than the initial. It happens because of the stability of the bond, the system wants a lower energy state to be stable.
The ionization of a lithium atom occurs with the gain of energy, which is given to the electron, so it may give off the atom. So it's an endothermic process.
To change the state of a solid to a gas (sublimation), the compound must gain heat, its temperature must increase, so it's always an endothermic process.
To break a covalent bond it's necessary the gain of energy, so it's an endothermic process.
