Answer:

ATGGCCTA

Explanation:

For this we have to keep in mind that we have a specific relationship between the nitrogen bases:

-) When we have a T (thymine) we will have a bond with A (adenine) and viceversa.

-) When we have C (Cytosine) we will have a bond with G (Guanine) and viceversa.

Therefore if we have: TACCGGAT. We have to put the corresponding nitrogen base, so:

TACCGGAT

ATGGCCTA

Which of the following about a balanced chemical reactions is

gavmur [86]

Answer:

A balanced chemical equation must always include coefficients on every reactant and product.

Explanation:

A balanced chemical equation does not need to include coefficients on every reactant and product.

For example, below is a balanced chemical equation in which the reactants and the products have no coefficients whatsoever:

NaOH(aq) + HCl (aq) -----> NaCl (s) + H2O (l)

Of course, a properly written chemical equation must include the states of matter of all the substances in the reaction and the number of atoms of each element must balance both in the reactant and product sides of the equation. Generally, a balanced chemical equation must obey the law of conservation of matter which opines that matter can neither be created nor destroyed but can only be converted from one form to another.

Hence, that a balanced chemical equation must always include coefficients on every reactant and product is not true.

A cylinder of iron has a mass of 23.45 g. If it is placed on an electronic balance that reports all masses 18.00% too low due to

Ganezh [65]

For the answer to the question above asking what mass will the balance report for the cylinder of iron if a cylinder of iron has a mass of 23.45 g. If it is placed on an electronic balance that reports all masses 18.00% too low due to miscalibration,
A cube has a volume of 8.0 cm3 and a mass of 21.6 grams
Using an electronic analytical balance of graduated cylinder.
The density of iron is 7.87 g/mL.

While performing the Acid-catalyzed Hydrolysis of Epoxides experiment you used a solution containing 1.84 mL of cyclohexene oxid

Elenna [48]

Answer:

The moles of starting material is $1.8212 \times 10^{-2}$ mole

Explanation:

Given:

Cyclohexene oxide material is used

Density = 0.97 $\frac{g}{mL}$

Volume = 1.84 mL

Formula of Cyclohexene oxide = $C_{6} H_{10} O$

Molar mass is given by,

$C = 6 \times 12 = 72$

$H = 10 \times 1 = 10$

$O = 1 \times 16 = 16$

⇒ $m' = 96\frac{g}{mol}$

Mass $m = 0.97 \times 1.84 = 1.7848$ $g$

Moles is given by,

$n = \frac{m}{m'}$

$n = \frac{1.7848}{98}$

$n = 1.8212 \times 10^{-2}$ mol

Therefore, the moles of starting material is $1.8212 \times 10^{-2}$ mole
