Iodine is a solid at STP (standard room temperature and pressure) as the intermolecular forces between the iodide compound is strongly held by bonds such as electrostatic forces of attraction if its a ionic compound. Therefore STP is so sufficient enough to breakthrough these bonds hence its a solid. However, chlorine’s a gas as its intermolecular bonds are weak, and STP is strong enough to break these bonds of where chlorine is a gas
NOTE: they should really give you a compound so you can identify between covalent and ionic bonds and talk about it in more depth
Answer: enzymes.
Explanation:
Microbial products are products derived from microorganisms. They may be primary or secondary metabolites. They are known to be environment friendly since they have biological origin. They are often degraded by enzymes which are also biological molecules. Degradation of materials using enzymes typically generates nontoxic products.
Arsenic is a pure element. Elements (atoms) are the simplest building blocs excluding smaller elementary particles such as electrons, neutrons, quarks, protons etc.
This means that Arsenic can not be broken down any further by chemical change, only nuclear decay can cause the breakdown of large elements into smaller ones. Chemical change would be the combination of multiple elements into a compound or the decomposition of a molecule/compound into pure elements or smaller compounds.
<u><em>Answer: South America's climate is dominated by relatively warm regions, yet the continent can generally be grouped into 4 zones, tropical, cold, dry and temperate. Along the Equator, running from the Pacific Ocean eastward to the Atlantic Ocean is a wide climate zone of the continent that is tropical, humid and wet.</em></u>

Explanation:
Answer: The new volume that the air occupies at this temperature is 5.5 L
Explanation:
To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,

where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:

Putting values in above equation, we get:

Thus the new volume that the air occupies at this temperature is 5.5 L
