Answer:
true
Explanation:
all cells will have plasma membranes
Moles of cu = mass/Ar
= 5/Ar
=ans
1 mole = 24dm3
Vol of cu = ans/1 × 24dm3
=ans
sorry i have no calculator with me now
Answer: -
24 grams per kilogram.
Explanation: -
We know that
The mixing ratio = actual (measured) mass of water vapor (in parcel) in grams / mass of dry (non water vapor) air (in parcel) in kilogram
The saturation mixing ratio = mass of water vapor required for saturation (in parcel) in grams/ mass of dry (non water vapor) air (in parcel) in kilograms
Relative humidity = actual (measured) water vapor content/ maximum possible water vapor amount (saturation)
Thus saturation mixing ratio = Mixing ratio / relative humidity
= 6 / (25/100)
= 24
Under strongly acidic conditions aldoses become oxidised to dicarboxylic acids called aldaric acids
<h3>
What are aldaric acids?</h3>
The formula for aldaric acids is HOOC-(CHOH)n-COOH, and they are a kind of sugar acids in which the sugars' terminal hydroxyl and carbonyl groups have been substituted by terminal carboxylic acids.
Aldoses are often oxidised with nitric acid to produce aldaric acids. The open-chain (polyhydroxyaldehyde) form of the sugar interacts in this reaction.
Aldoses that have both the hydroxyl function of the terminal carbon and the aldehyde function of the first carbon completely oxidised to carboxylic acid functions are referred to as aldaric acids. (Aldonic acid is produced by oxidising just the aldehyde, whereas uronic acid is produced by oxidising only the terminal hydroxyl group.) Like unoxidized sugars, aldaric acids cannot produce cyclic hemiacetals, but they occasionally can form lactose.
