Answer:
Mixture of two elements
Explanation:
You can tell that it is an element since the atoms are only bonded to atoms of the same type. It is a mixture since the molecules are together in solution but aren't bonded together.
Paul J. Chirik developed methods associated with chemistry catalysis and transition metals, which may result useful for the development of manufacturing technologies.
<h3>What is catalysis?</h3>
Catalysis refers to the chemical processes that increase the rate of different types of reactions by lowering its activation energy.
Proteins (enzymes) are biological catalysts that increase the rate of chemical reactions in biological systems.
Catalysis may be reached by using transition metals (e.g., actinium and rutherfordium), which result useful in the development of manufacturing technologies.

Answer:
It lets people prepare for future weather hazards:
- If, in certain months and on certain dates, the past data shows that there's a history of rain or heat stroke on those days, people can prepare in the future for those events.
- They can also expect wind speeds, temperatures and stuff like that!
Answer:
Are difficult to compress.
Explanation:
Answer:
pH value of a solution depends on the concentration of hydrogen ions
(pH = -log[H+(aq)].
Hydrochloric acid is a strong acid, while ethanoic acid is a weak acid. Strong acids ionize completely in water (to give ions which includes H+(aq)), while weak acids only ionize partially in water.
Therefore, even if both hydrochloric acid and ethanoic acid are monobasic acids (each molecule can ionize completely to give 1 hydrogen ion), since hydrochloric acid ionizes completely in water and ethanoic acid does not ionize completely, the concentration of hydrogen ions in hydrochloric acid is higher than that of ethanoic acid, leading to a lower pH value for hydrochloric acid, while higher for ethanoic acid.
