<span>Ans : You know the mass of KHC8H4O4, therefore you know the moles of it. No matter how much water you add to the KHC8H4O4 the number of moles will never change. However, if you add water to NaOH that changes the concentration which would effect the number of moles used titrating.</span>

What happened to a balloon when it is put in freezer
e-lub [12.9K]

The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.

How can a charged atom (an ion) attract a neutral atom? 1. the charged atom can hit the neutral atom and make it positively char
Ivan
The answer would be 2. <span>an ion polarizes a nearby neutral atom, so that the part of the atom nearer to the ion acquires a charge opposite to the charge of the ion, and the part of the atom farther from the ion acquires a charge of the same sign as the ion

In neutral atoms, the negative and positive charge spread evenly. The charge from an ion could create an electric field that will attract the charge of the neutral atoms.
The neutral atoms charge sum still zero, but the distribution of charge could be changed.</span>

How much copper is present in a cube that measures 3.20cm on each side, if the density of copper is 8.96 g/mL
Ainat [17]

Answer:

290.32 g

Explanation:

First we <u>calculate the volume</u> of the cube:

  • Volume = (3.20 cm)³ = 32.768 cm³

Now we <u>convert cubic centimeters to mililiters</u>:

  • 32.768 cm³ * 1 mL / 1 cm³ = 32.768 mL

Finally we <u>calculate the mass</u>, using the <em>equation for density</em>:

  • Density = mass / Volume
  • mass = Density * Volume
  • mass = 8.86 g/mL * 32.768 mL = 290.32 g
