Answer:O B. Weak acid breaks down minerals by reacting with them.
Explanation:
Chemical weathering is the process whereby rain water which sometimes can be acidic ( As rain falls down it reacts with CO2 in the atmosphere and form acid rain), This reacts with the minerals contained in rocks, dissolves and degrades them further to form entire new minerals.
An example of a rock that is greatly affected by overexposure of acid rain is limestone containing calcite which easily degrades by acid rain.
Other processes whereby Chemical weathering can occur are through reaction with water and oxygen.
Answer:
CO
Explanation:
Henry's law constant reflects the solubility of a gas in water. The larger the kH, the more soluble is the gas. There is a rule that states that "like dissolves like", meaning polar is soluble in polar and nonpolar is soluble in nonpolar. Since water is polar, we have to consider the nature of these gases.
<em>Xe</em> nonpolar
<em>Cl₂</em> nonpolar
<em>CO</em> polar
<em>CO₂</em> nonpolar
<em>CH₃CH₃</em> nonpolar
CO is the only polar gas, so it has the largest kH.
How does one determine the identity and structure of an unknown compound? This is not a trivial task. Modern x-ray and spectroscopic techniques have made the job much easier, but for some very complex molecules, identification and structure determination remains a challenge. In addition to spectroscopic information and information obtained from other instrumental methods, chemical reactions can provide useful structural information, and physical properties can contribute significantly to confirming the identity of a compound.
In this experiment, you will be asked to identify an unknown liquid, which will be either an alcohol, aldehyde, or ketone. Identification will be accomplished by carrying out chemical tests, called classification tests, preparing a solid derivative of the unknown and determining its melting point (MP), making careful observations, and analyzing the NMR spectrum of the unknown.

1.Strong basses dissociates into ions almost 100%.
But weak basses partially dissociates into ions.
2.Strong basses has pH value smaller but closer to 14 and weak basses has pH value greater but cloaer to 7.
3.strong basses ate highly reactive whereas weak basses are less reactive.
I believe it’s a because something cannot move unless a force is acted upon it
