Final answer:
In DNA, the nitrogenous bases are represented by A for Adenine, T for Thymine, C for Cytosine, and G for Guanine. Adenine pairs with Thymine, and Cytosine pairs with Guanine, through hydrogen bonds.
Explanation:
In DNA, there are four nitrogen bases represented by the letters A (Adenine), C (Cytosine), G (Guanine), and T (Thymine). These bases form complementary base pairs, with A pairing with T, and C pairing with G. The bases are held together by hydrogen bonds, with A and T sharing two hydrogen bonds, while C and G share three. These bases are differentiated by their ring structures: Adenine and Guanine are double-ringed structures called purines, while Cytosine and Thymine are single-ringed structures known as pyrimidines. The pairing always occurs between one purine and one pyrimidine, which helps maintain the uniform shape and structure of the DNA molecule.

Answer: a)
b) 92.1 g
Explanation:
To calculate the moles, we use the equation:
a) moles of
b) moles of
According to stoichiometry :
1 mole of require 2 moles of
Thus 1.173 require=
of
Thus is the limiting reagent as it limits the formation of product. Thus
will run out first.
is the excess reagent as (3.500-2.346)= 1.154 moles are left unreacted.
2 moles of require 1 mole of
3.500 moles of require=
of
Moles of required = (1.750-1.173) = 0.577
Mass of
Thus he should order 92.1 g of the limiting reactant.

d. protons, neutrons or electrons
Answers
When neutrons are added to an atomic nucleus, energy is produced and this is called a fusion reaction. The answer is letter B. To be exact, two nuclei combine to produce a more stable nucleus. The positive charge on both nuclei result in a large electrostatic energy barrier to fusion.
The correct answer is c because the nuc are combing more protns and neutrons. The answer suposed to be protons and neutrons NOT PROTONS OR NEUTRONS?!!
