The first part of the scientific method is the observation. Therefore, 2. is the first step.

The second step is the hypothesis. Therefore, 1. is next.

The third step is the experiment. Therefore, 3. is next.

The final step is the conclusion. Therefore, 4. is last.

The order is:
2.
1.
3.
4.

What is the acceleration of a ball traveling horizontally with an initial velocity of 20 meters/second and, 2.0 seconds later, a
Pepsi [2]

Answer: <em>Acceleration of the ball in the given system is 5 meter per Second Square</em>

<em>The laws of motion are used to determine various aspects of an object in motion</em>.

Explanation:

Applying the first law of motion to calculate acceleration; if formula used in first law is given as v=u+at

Here we have a final velocity as 40 meter per second and initial velocity as 20 meter per second and time span is given as 2 second applying the given values in the given equation and finding the value of a

What is the OH in a solution made by adding 0.060 mole of calcium oxide to 500.0ml
Alex73 [517]

Answer:

0.24 mol/L.

Explanation:

  • Ca(OH)₂ dissociates in solution according to the equation:

<em>Ca(OH)₂ → Ca²⁺ + 2OH⁻.</em>

<em></em>

Every 1.0 mol of Ca(OH)₂ dissociates to give 2.0 moles of OH⁻.

∴ The no. of moles of OH⁻ produced from 0.06 mol of Ca(OH)₂ = (2 x 0.06 mol) = 0.12 mol.

<em>∴ [OH⁻] = no. of moles / V of the solution</em> = (0.12 mol)/(0.5 L) = <em>0.24 mol/L.</em>

Indicate the types of forces that are involved between the solute and solvent when forming a homogeneous solution between CH3CH2
Sliva [168]

Answer:

London dispersion forces

Explanation:

Intermolecular forces are the forces that facilitate interaction between solute and solvent molecules and thereby impact their solubility. These forces are broadly classified into four types arranged below from the strongest to the weakest:

1) Ionic > 2) Hydrogen bonding >3) Dipole-dipole >4) London dispersion

The hydrocarbons n-pentane CH_{3}CH_{2}CH_{2}CH_{2}CH_{3} and n--hexane CH_{3}CH_{2}CH_{2}CH_{2}CH_{2}CH_{3} are non-polar molecules. Therefore the only type of interaction that exists between them when forming a homogeneous solution are the weak london dispersion forces.
