Answer:
The two enzymes that are used during DNA replication is helicase and polymerase. Each enzyme has distinct role that made it a vital part of the replication. In the course of DNA replication, the initial stage is to unzip the double helix structure of the DNA molecule by the enzyme helicase, which breaks the hydrogen bonds that holds the complementary bases of DNA.
Moreover, the DNA polymerase has the ability to exactly copy a DNA template. This enzyme binds to the leading strand and then adding a new complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.

Let's do it like this...
The question says write a balanced equation for the reaction between aqueous lead(II) nitrite and aqueous potassium chloride to form solid lead(II) chloride and aqueous potassium nitrite...
Analysising
________________________________________________________
Aqueous Lead(II) Nitrate written as a Formula is Pb(NO3)2 and Aqueous potassium written as a Formula is KOH.......and.......here the statement says they form Solid lead(ll) chloride which is PbCl₂ and aqueous potassium nitrite which is KNOH3
so The unbalanced equation will be
Pb(NO3)2 + KCL ====> PbCl2 + KNOH3
________________________________________________________
New Balanced Equation
________________________________________________________
Pb(NO3)2 + 2KCL ====> PbCl2 + 2KNOH3
(Balanced) RHS = LHS
Explanation:
Balancing The Equation
Lead (Pb) Has a coefficient of 1 both side.(Balanced)
Nitrate (NO3) has 2 as their coefficient both sides. (balanced)
Potassium (K) has a coefficient of 2 in the left so in the right. (balanced)
Chlorine (Cl) has also a coefficient of 2 in the right so in the left. (balanced)
Therefore the equation is balance the LHS equals to the RHS
NB : There's no any balanced equation than this
Answer:
Are long chains of sugar units arranged to form starch or fiber.
Explanation:
The carbohydrates are compounds formed by carbon (C), hydrogen (H) and oxygen (O), and they are composed for single or multiple sugars. When composed by a single sugar (as glucose) it's called a simple carbohydrate, or monosaccharide. When it's composed of two units of sugar, it's called a disaccharide.
The carbohydrates that are composed of a long chain of sugar units are called polysaccharides, or complex carbohydrates, and they are the complex sugars used as energy reservations or as structural, so they from starch or fiber.
Explanation:
a.H2PO4 + 2KOH = K2PO4 + 2H2O
b. H2PO4 _ 2KOH
1(2) + 31 + 16(4) _ 2(23) + 2(16) + 2(1)
2 + 31 + 64 _ 46 + 32 + 2
97 _ 80
no of moles of H2PO4 = 2.5 ÷ 97
= 0.026mol
no of moles of 2KOH = 4 ÷ 80
= 0.05mol
2KOH is the limiting reactant
c. H2PO4 is the excess reactant
d. 1 mole H2PO4 weighs 2.5g
0.026mol H2PO4 weighs g
(0.026 × 2.5)
H2PO4 weighed 0.065g after reaction
