No, many liquids have surface tension such as mercury.

Mkey [24]3 years ago

Answer:

Water has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds. That means a drop of water will "want" to have the smallest possible surface area.

What volume of 2.0 NaOH is required to neutralize 25.0 ml of 2.70 N H2SO4?<br>​
Viktor [21]

Write the equation for the reaction and balance it. In this case the equation is: 2NaOH + H2SO4 → Na2SO4 + 2H2O

Convert the given amount to moles. Molarity, “M” is moles per liter. The given amount is 25 ml of 1.2 M H2SO4. Since Molarity uses Liters, the volume must be converted from ml to L.

Use the mole ratio in this case 2 moles of NaOH to ! mole of H2SO4

Convert the moles to the required units. In this case the required units are grams. The formula weight in grams er mole.

25 ml H2SO4 * 1L/1000 ml * 1.2 Moles/L * 2 moles NaOH/1 mole H2SO4 * 40 g NaOH/ 1 Mole NaOH

Perform these calculations and you have the answer! Timothy, When doing homework, the answer is NOT the important thing, the METHOD is! These 4 steps, combined with required changes in units will sove ANY stoichiometric problem easily.

A ball has a 17 j of kinetic energy and its mechanical energy is 25 j. Calculate its potential energy
ycow [4]

The potential energy of the ball is 8 J.

<h3>What is mechanical energy?</h3>

Mechanical energy is given as the energy possessed by an object to do work. It is given as the sum of the kinetic energy and potential energy.

Mechanical energy = Kinetic energy + Potential energy

The given ball has:

  • Mechanical energy = 25 J
  • Kinetic energy = 17 J

The potential energy is given as;

25 J = 17 J + Potential energy

Potential energy = 25 J - 17 J

Potential energy =  8 J

The potential energy of the ball is 8 J.
