Answer:

pOH = 1.3, pH = 12.7

Explanation:

Since NaOH is a strong base, it will completely ionize; further, since it completely ionizes, our hydroxide concentration (a product of the ionization) will be the same as the given concentration of NaOH.

NaOH -> Na⁺ + OH⁻, [OH⁻] = 5.0 x 10^-2 M

pOH is the negative log of the hydroxide concentration, so plug our hydroxide concentration in:

pOH = -log[OH⁻] = -log[5.0 x 10^-2 M] = 1.3

Since pH + pOH = 14, we can plug in pOH and solve for pH:

pH + 1.3 = 14

pH = 14 - 1.3 = 12.7

Thus, our pOH = 1.3 and pH = 12.7.

Explanation:

answer: the earth orbits around the sun for 365 while getting older to the young theory.

Answer:

The older theory was that the sun (and other planets) revolved around earth and the new theory is that the earth (and other planets) revolved around the sun.

Eukaryotes

Explanation:

Answer:

94.1 %

Explanation:

We firstly determine the equation:

2H₂O + O₂ →  2H₂O₂

2 moles of water react to 1 mol of oxygen in order to produce 2 moles of oxygen peroxide.

We convert the mass of oxygen to moles:50 g . 1mol /32g = 1.56 mol

Certainly oxygen is the limiting reactant.

2 moles of water react to 1 mol of oxygen.

13 moles of water may react to 13/2 = 6.5 moles. (And we only have 1.56)

As we determine the limiting reactant we continue to the products:

1 mol of O₂ can produce 2 moles of H₂O₂

Then 1.56 moles of O₂ will produce (1.56 . 2) = 3.125 moles

We convert the moles to mass: 3.125 mol . 34 g/mol= 106.25 g

That's the 100% yield or it can be called theoretical yield.

Percent yield = (Yield produced / Theoretical yield) . 100

(100g / 106.25 g) . 100 = 94.1 %

Given :

A sample of unknown gas has a temperature of 378 K.

[tex]T_i = 378 \ K , \ T_f = 546 \ K[/tex]

When the temperature is increased to 546 K, the volume also increases to 1047 ml.

[tex]V_f - V_i = 1047 \ ml[/tex]

Solution :

We know, temperature is directly proportional to volume.

[tex]\dfrac{T_i}{T_f}=\dfrac{V_i}{V_f}\\\\\dfrac{T_i}{T_f} = \dfrac{V_i}{1047 + V_i}\\\\\dfrac{V_i}{1047+V_i}=\dfrac{378}{546}\\\\546V_i = 378V_i + 378\times 1047\\\\168V_i = 3,95,766\\\\V_i = 2,355.75\ ml[/tex]

Therefore, the original volume is 2.355.75 ml.

Answer:

the mass of the glycerine needed in the given solution is  23.92 g

Explanation:

Given;

molarity of the solution (C₃H₈O₃), C = 2.60 M

Volume of the solution, V = 100 mL = 100 x 10⁻³ L = 0.1 M

The molarity of a solution is given as follows;

[tex]Molarity = \frac{amount \ of \ solute \ (moles)}{volume \ of \ solution \ (L)} \\\\amount \ of \ solute \ (moles) = Molarity \ \times volume \ of \ solution \ (L)\\\\amount \ of \ solute \ (moles) = 2.6 \times 0.1 \\\\amount \ of \ solute \ (moles) = 0.26 \ mole[/tex]

The molecular mass of the given solution;

molecular mass = (12 x 3) + (8 x 1) + (16 x 3)

molecular mass = 92 g/mol

The mass of the glycerine needed in the given solution is calculated as follows;

reacting mass = amount of solute (moles)   x   molecular mass (g/mol)

reacting mass = 0.26 x 92

reacting mass = 23.92 g

Therefore, the mass of the glycerine needed in the given solution is  23.92 g

Answer:

This lifespan began roughly 4.6 billion years ago, and will continue for about another 4.5 – 5.5 billion years, when it will deplete its supply of hydrogen, helium, and collapse into a white dwarf.

Answer:

It's D. Francium

Explanation:

Atomic radii vary in a predictable way across the periodic table. The atomic radius increases from top to bottom in a group and decreases from left to right across a period. Thus, Helium is the smallest element, and Francium is the largest.

Answer:

1st Diagram (at the left) → Mid-Atlantic Ridge

2nd Diagram (at the right) → Andes Mountains

3rd Diagram (below) → San Andreas Fault

Explanation:

I have been able to label the diagram with the correct information.

The 1st diagram at the left is the Mid-Atlantic Ridge. This is a divergent plate boundary that is found at the floor of the Atlantic Ocean. It is also seen as part of the mountain range in the world. The Mid-Atlantic Ridge also includes a deep rift valley. This rift valley runs along the axis of the ridge. This is along nearly its entire length.

The Andes Mountains is found along the Pacific Ring of Fire. It is seen in a Mesozoic–Tertiary orogenic belt of mountains. The Andes rises due to the compression of the western rim of the South American Plate. It is a result of tectonic plate processes.

San Andreas Fault is known to form the tectonic boundary which exists between the Pacific Plate and the North American Plate. The motion of the fault is right-lateral strike-slip. It divides into three segments.
