How many liters of the antifreeze ethylene glycol [CH2(OH)CH2(OH)] would you add to a car radiator containing 6.50 L of water if

the coldest winter temperature in your area is -10.°C? (The density of ethylene glycol is 1.11 g/mL. Assume the density of water at -10.°C is 1.00 g/mL.)

Answer: 2.04L

Explanation:

coldest temperature = -10°C

mass of solvent = 6.50kg

freezing point depression = kb*m

Where kb = molar freezing point depression constant, 1.86

10 = 1.86 * molality of ethylene glycol

10 = 1.86 * moles of ethylene glycol/mass of solvent

10 = 1.86 * moles of ethylene glycol/6.5

10*6.5 = 1.86 * moles of ethylene glycol

Moles of ethylene glycol = 65/1.86

Moles of ethylene glycol = 36.11

36.11 mol * 62.1 g/mol = 2242.43g = 2.24kg

1 L = 1000 mL x 1.11 g/mL = 1100 g = 1.1 kg

2.24 kg / 1.10 kg/L = 2.04 L

When an oxidant is present, vitamin C can be converted to a product described as (5R)-5-[(1S)-1,2-dihydroxyethyl]-3,4-dihydroxy-
Step2247 [10]

Answer:

D) Vitamin C is oxidized to yield a furan ring with 3 carbonyl groups and no double bonds

Explanation:

We can tell that the compound " (5R)-5-[(1S)-1,2-dihydroxyethyl]-3,4-dihydroxy-furan-2,3,4(5H)-trione " has 3 carbonyl groups due to it having "trione" in the name (and it lacking other carbonyl group names, like amide or carboxylic acid).

As there is no "-ene" part of the name referencing a double bond, the only option left is option D).

Q, R, S, P is the order of apparent magnitude of the stars, starting from the least to the greatest.

Answer: Q, R, S, P

<u>Explanation:</u>

The apparent magnitudes of the star is the brightness calculated by an observer at a particular distance from the Earth. The smaller the distance between the star and the Earth, the greater the apparent brightness.

So , from the given distance (in light years), Q,R,S,P is the answer (least to the greatest apparent magnitude) (distance is greatest to least).

compare and contrast neap tides and spring tides discuss when they occur as well as the alignment of the earth moon sun system
seropon [69]
Spring tides is when the daily tidal range is greatest and neap tides are when the daily tidal range is the smallest. As for alignment, spring tides occur when the earth, moon, and sun are directly in alignment with each other. Neap tides occur when the earth is in alignment with the sun, but the moon is at a 90 degree angle from that
