Answer:

U A G C C A U C G G A U C C G A U

Explanation:

In DNA, A=T, C=G, and vice versa. RNA has U instead of T. So dna to rna: adenine = uracil, thymine = adenine, cytosine = guanine, and guanine = cytosine.

Which of these are equal to 6.02 x 1023 particles? 12.01 g carbon (C) 44.08 g of silicon dioxide (SiO2) 16 g of ozone (O3) 16.04

ki77a [65]

It is known that 1 mol of a substance is equal to 6.02x10^3 particles. This is called the Avogadro's number. From this knowledge, we convert the mass of the substances given above into units of moles by using the molar mass.

12.01 g C ( 1 mol / 12.01 g) = 1 mol
44.08 g SiO2 ( 1 mol / 60.08 g ) = 0.73 mol
16 g of O3 (1 mol / 48 g) = 0.33 mol
16.04 g CH4 (1 mol / 16.05 g ) = 0.99 mol

So, the answers are carbon and carbon tetrahydride.

The pOH of a solution is 6.0. Which statement is correct? Use p O H equals negative logarithm StartBracket upper O upper H super

Katen [24]

Answer:

The pH of the solution is 8.

Explanation:

To which options are correct, let us determine the concentration of the hydroxide ion, [OH-] and the pH of the solution. This is illustrated below:

1. The concentration of the hydroxide ion, [OH-] can be obtained as follow:

pOH = –Log [OH-]

pOH = 6

6 = –Log [OH-]

–6 = Log [OH-]

[OH-] = Antilog (–6)

[OH-] = 1x10^–6 mol/L

2. The pH of the solution can be obtained as follow:

pH + pOH = 14

pOH = 6

pH + 6 = 14

pH = 14 – 6

pH = 8.

From the calculations made above,

[OH-] = 1x10^–6 mol/L

pH = 8.

Therefore, the correct answer is:

The pH of the solution is 8

3. Methane (CH4) behaves as an ideal gas under standard temperature and pressure conditions. What volume is occupied by 1 kg of

AlekseyPX

Answer:

1711.11L

Explanation:

Given parameters:

Mass of methane = 1kg = 1000

Temperature of gas = 35°C

Pressure of the gas = 0.9atm

Converting to the temperature to kelvin, we have:

35+ 273 = 308k

Solution

From the given parameters, we can solve this problem using the ideal gas equation which is combination of the gas laws. It is expressed below:

PV = nRT .......................(i)

Where P is the pressure of the gas

V is the volume of the gas

n is the number of moles

R is the gas constant

T is the temperature

Now, from the above parameters, we have two unknowns which are n and V.

To find the number of moles n, we use the expression below:

number of moles = $\frac{mass}{molar mass}$

molar mass of methane = 12 + (4x1) = 16g/mol

Number of moels of methane = $\frac{1000}{16}$ = 62.5mole

Now that we know the number of moles, we can make the unknown Volume the subject of the formula:

V = $\frac{nRT}{P}$

V = $\frac{62.5 x 0.082 x 308}{0.9}$ = 1711.11L
