Answer:

downwelling also allows for deep ocean oxygenation to occur because these waters are able to bring dissolved oxygen down from the surface to help facilitate aerobic respiration in organisms throughout the water column

Which is not a reason why mass of an atom is expressed in atomic mass units rather than in grams?
Tasya [4]
What are your answer choices? Scientists express the weight in AMU’s so that they can easily think about the weight of the atom. If it is expressed in grams, they’re constantly dealing with a weight that’s around 10^-24 grams, which is hard to deal with.

A 1.450 g sample of an unknown organic compound , X, is dissolved in 15.0 g of toluene
muminat

Answer:

Molecular weight of the compound = 372.13 g/mol

Explanation:

Depression in freezing point is related with molality of the solution as:

\Delta T_f = K_f \times m

Where,

\Delta T_f = Depression in freezing point

K_f = Molal depression constant

m = Molality

\Delta T_f = K_f \times m

1.33 = 5.12 \times m

m = 0.26

Molality = \frac{Moles\ of\ solute}{Mass\ of\ solvent\ in\ kg}

Mass of solvent (toluene) = 15.0 g = 0.015 kg

0.26 = \frac{Mole\ of\ compound}{0.015}

Moles of compound = 0.015 × 0.26 = 0.00389 mol

Mol = \frac{Mass\ in\ g}{Molecular\ weight}

Mass of the compound = 1.450 g

Molecular\ weight = \frac{Mass\ in\ g}{Moles}

Molecular weight = \frac{1.450}{0.00389} = 372.13\ g/mol

How does skin protect the body from pathogens?
andreev551 [17]
Skin is a barrier that serves as one of the body's first lines of defense against harmful microbes. Specialized immune cells within skin tissue help to fight invading organisms. Yet the skin hosts diverse communities of beneficial bacteria, collectively known as the skin microbiota.

why is iodine is a solid at STP but chlorine is a gas at STP? explain in terms of intermolecular forces.
Lerok [7]
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
