What is the sequence of cases on dna strand b from left to right? (See picture)
Bas_tet [7]

Answer:Dna template- 5' ACTCCTGAA 3'

3' TGAGGACTT 5' complementary base

Explanation: Dna consist of a double stranded helix structure. Replication occurs to make extra copies of DNA strand. The DNA strand use to make extra copy is the template strand while the mirror image is the complementary base.

Replication occurs in 5' to 3' direction.

For complementary base in DNA Adenine complement thyamine

Cytosine complement Guanine

i.e A-T

C-G

Hence the complementary base in 3'-5' direction is 3' TGAGGACTT 5'

What will be the theoretcal yield of tungsten(s) ,W, if 45.0 g of WO3 combines as completely as possible with 1.50 g of H2? WO3(
7nadin3 [17]

Answer:

Theoretical yield of tungsten produced = 35.6836915592  ≈ 35. 68 g

Explanation:

The chemical equation can be expressed as follows;

WO3 (s) + 3H2(g) → W(s) + 3 H20(g)

Note that the equation is already balanced.

Molecular Mass of WO3= 183.84 + 15.999 × 3 = 183.84 + 47.997  = 231.837 g

From the equation 1 mole of WO3 reacts with 3 mole of hydrogen molecule.

Molecular mass of tungsten(W) = 183.84 g

1 mole of tungsten was produced from the chemical equation.

WO3 (s) + 3H2(g) → W(s) + 3 H20(g)

From the equation,

231. 837 g of WO3 produces 183.84 g of tungsten

45.0 g of WO3 will produce ?

grams of tungsten produced = 183.84 × 45 /231.837

grams of tungsten produced = 8272.8 /231.837

Theoretical yield of tungsten produced = 35.6836915592  ≈ 35. 68 g
