<u>Explanation:</u>

<u>1. Have many moons:</u>

  • Jupiter is the fifth planet from the Sun and the biggest in the Solar System and it has fifty-three moons which are confirmed and twenty-six provisional moons and totally it has seventy-nine moons and it is the only planet which has many moons.

<u>2. Have a rocky composition:</u>

  • The planets which have rocky composition are also called the terrestrial planets.
  • The planets which have rocky composition are listed below mercury, venus, earth, and mars and they are smaller in size.

<u>3. Revolve quickly around the Sun: </u>

  • Mercury is the quickest planet, which rushes around the sun at 47.87 km/s. And it revolves around the sun quickly.

<u> 4. Rotate quickly on their axes: </u>

  • The giant gas planets like Jupiter, Saturn, etc... spin more quickly on their axes than the other planets

IgorC [24]
<span>Answer: 2 C8H18 + 25 O2 => 16 CO2 + 18 H2O 1.0 kg = 1000 g C8H18 = 1000 g / 114.2293 g/mole = 8.75 moles C8H18 8.75 moles C8H18 produce (16/2) (8.75) = 70 moles CO2 70 moles CO2 = (70 moles) (44.0096 g/mole) = 3081 g CO2 = 3.1 kg CO2</span>

Leo carefully pipets 50.0 mL of 0.500 M NaOH into a test tube. She places the test tube
Bess [88]

Let's consider the neutralization reaction between HCl and NaOH.

NaOH + HCl ⇒ NaCl + H₂O

To determine the pH of the resulting mixture, we need to determine the reactant in excess. First, we will calculate the reacting moles of each reactant.

NaOH: 0.0500 L × 0.500 mol/L = 0.0200 mol

HCl: 0.0750 L × 0.250 mol/L = 0.0188 mol

Now, let's determine the reactant in excess and the remaining moles of that reactant.

                    NaOH    +     HCl ⇒ NaCl + H₂O

Initial           0.0200       0.0188

Reaction    -0.0188       -0.0188

Final         1.20 × 10⁻³          0

The volume of the mixture is 50.0 mL + 75.0 mL = 125.0 mL. Then, 1.20 × 10⁻³  moles of NaOH are in 125.0 mL of solution. The concentration of NaOH is:

[NaOH] = 1.20 × 10⁻³ mol/0.1250 L = 9.60 × 10⁻³ M

NaOH is a strong base according to the following equation.

NaOH ⇒ Na⁺ + OH⁻

The concentration of OH⁻ is 1/1 × 9.60 × 10⁻³ M = 9.60 × 10⁻³ M.

The pOH is:

pOH = -log [OH⁻] = -log 9.60 × 10⁻³ = 2.02

We will calculate the pH using the following expression.

pH = 14.00 - pOH = 14.00 - 2.02 = 11.98

The pH is 11.98. Since pH > 7, the solution is basic.
