An ionic compound is the attraction between a metal and a nonmetal!!
ElenaW [278]3 years ago
4 0

Lattice energy is a way to measure the bond strength in ionic compounds.

Ionic compounds tend to have high melting and boiling points.

Ionic compounds tend to be hard.

Ionic compounds have a range of solubilities.

Ionic compounds are not conductors in the solid state, but they are good conductors as liquids or in solution.

Which observation provided Albert Einstein the clue that he needed to explain the photoelectric effect? Light is made up of extr
Aliun [14]

The correct answer is

Energy of electrons depends on light’s frequency, not intensity.

As per photoelectric effect, if we incident a light on metal surface it will results into emission of electron from it

if we increase the number of photons the number of electrons will increase however if we increase the frequency the number of photons will not increase

While if we increase frequency the energy of electrons will increase as

Energy of photon = Work function of metal + kinetic energy of electrons

Why is it impossible to ever prove that a hypothesis is true?
maria [59]

Answer: A

Explanation:

Hypothesis have to be based on previous knowledge and have to be able to be tested but the problem is most hypothesis can’t be explained so it’s impossible to prove a hypothesis correct because science uses inductive reasoning

44.8% of a 250. mL acid solution is used in an experiment, what volume of acid (in mL) was used?
postnew [5]

Answer:

112 mL  

Explanation:

The formula for percent by volume is

\text{Percent by volume} = \dfrac{\text{Volume of solute}}{\text{Volume of solution}}\times 100 \, \%

If you have 250 mL of a solution that is 44.8 % v/v,

\begin{array}{rcl}44.8\, \% & = & \dfrac{\text{Volume of solute}}{\text{250 mL}}\times 100 \, \%\\\\44.8 \times \text{ 250 mL} & = & \text{Volume of solute} \times 100\\\text{Volume of solute} & = & \dfrac{44.8 \times 250\text{ mL}}{100}\\\\ & = & \textbf{112 mL}\\\end{array}

Please Explain. Why does salt water boil at a lower temperature than tap water?
nexus9112 [7]
We observe that heat capacity of salted water we will find that it is less than pure water. We now that it takes less energy to increase the temperature of the salt water 1°C than pure water. Which means that the salted water heats up faster and eventually reaches to its boiling point first.
hope it helps
