<span>Heat would make the molecules move faster so they would spread out therefore making air less dense.
Less dense means less packed. Heat increase the kinetic energy</span>
Solution : As they have uniform composition throughout they are considered as homogeneous mixture. Both samples are mixture of two metals (gold and palladium) thus are alloys.
Yes, because beryllium is less dense and harder than oxygen.
When water chemically combines with carbon dioxide, a Carbonic acid is formed.
<u>Explanation</u>:
- Carbon dioxide responds with water in a solution to form a weak acid, carbonic acid. Carbonic acid disassociates into hydrogen particles and bicarbonate particles. The hydrogen particles and water respond with the most basic minerals modifying the minerals.
-
Carbon dioxide and the other atmospheric gases disintegrate in surface waters. Dissolved gases are in equilibrium with the gas in the atmosphere. Carbon dioxide responds with water in a solution to form the weak acid, carbonic acid. Carbonic acid disassociates into hydrogen particles and bicarbonate particles.
-
The hydrogen particles and water respond with the most basic minerals altering the minerals. The results of enduring are prevalently clays and soluble particles, for example, calcium, iron, sodium, and potassium. Bicarbonate particles additionally remain in solution; a remnant of the carbonic acid that was utilized to weather the rocks.
The substance is followed by H2O
