He should measure 27g

Explanation:

Zachary should measure out 27g of Aluminum.

27g of aluminium is the same as one moles of the element.

  • A mole is a substance that contains the avogadro's number of particles.

To do this, we know that the molar mass of aluminium is 27g/mol

This implies that it contains 27g of matter in 1 mole

Mass of a substance = number of moles x molar mass

Mass of a substance = 1 mole x 27g/mole = 27g

What is the complementary DNA sequence for C G T T A C C G in chargaff's rule?
djverab [1.8K]

Answer:

Chargaff's rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine.

Explanation:

In these nucleotides, there is one of the four possible bases: adenine (A), guanine (G), cytosine (C), or thymine (T) (Figure below). Adenine and guanine are purine bases, and cytosine and thymine are pyrimidine bases. Chemical structure of the four nitrogenous bases in DNA✔✔

What is the pH at the half-equivalence point in the titration of a weak base with a strong acid? The pKb of the weak base is 7.9
ValentinkaMS [17]

Hey there!

Given the reaction:

B + H⁺   => HB⁺


At half-equivalence point :  [B] = [HB⁺]

=> [B] / [HB⁺] = 1

Henderson-Hasselbalch equation :


pH = pKa + log ( [B] ) / ( HB⁺)]

pH = 14 - pKb + log ( 1 )

pH = 14 -  7.95 + 0

pH = 6.05


Answer C


Hope that helps!

Jokes from Savannah~

A man goes to the doctor, concerned about his wife’s hearing. The doctor says, “Stand behind her and say something and tell me how close you are when she hears you.”

The man goes home, sees his wife in the kitchen, cutting carrots on the countertop. About 15 feet away he says, “Honey, what’s for dinner?” Nothing. He gets halfway to her and repeats the same question. Nothing. Very concerned, he gets right behind her and asks again “What’s for dinner?”

She turns around and says “For the THIRD time, beef stew!”
