Increasing order of magnitude of lattice energy is rbi <K2s< Mgs < Ga2O3.

Lattice energy is the energy change upon the formation of one mole of a crystalline ionic compound from its constituent ions. It depends upon the charges of the ion and the distance between the center of the ion when they are packed in the form crystal. Basically lattice energy is determined by the charge of the atom and the atomic radii of the atoms.

In Ga2O3, Ga has 3+ and O has 2- ions .so it has the lattice energy of 6.this is calculated by multiplying q1 and q2 .this attracts strongly.

In rbI , R has +1 and i has -1.so it ha lattice energy of -1.ther is no strong attraction nor lattice energy.

In Mgs, Mg has +2 and s has -2 .this is not as strong as Ga2o3 but stronger than rbi.

In K2S, k has =1 and s has 2-.this is stronger than rbi.

A substance in which light can travel through such as air,glass, or water

Stels [109]

Answer:

The correct answer is - transparent medium.

Explanation:

A transparent substance or medium is the substance that allows light to pass through it. Light moves through these substances as they do not absorb the light and do not reflect too.

The example of such substances is glass, air or water. These substances allow light to pass through them.

Thus, The correct answer is - transparent medium.

3. What is the mass of HI used to create 2.50L of a 0.48 M solution of hydroiodic acid?

Daniel [21]

Answer:

Mass = 153.48 g

Explanation:

Given data:

Volume of solution = 2.50 L

Molarity = 0.48 M

Mass required = ?

Solution:

Molarity = number of moles / volume in litter

Number of moles = Molarity × volume in litter

Number of moles = 0.48 M × 2.50 L

Number of moles = 1.2 mol

Mass of HI:

Number of moles = mass/molar mass

Mass = Number of moles × molar mass

Mass = 1.2 mol × 127.9 g/mol

Mass = 153.48 g

What is missing from the temperature and volume graph shown at right?

Kaylis [27]

Answer: Three things are missing:

i) Graph title.

ii) Label for the vertical axis.

iii) The scale and the units for the horizontal axis.

Justification:

1) Find the graph in the image attached.

2) What does the graph represent? You cannot tell because it does not show the tittle.

Since you are told in the statement that it is a temperature and volume graph, the appropiate title would be:

Temperature vs. Volume.

3) The vertical axis also must be properly labeled, including the units.

A good label for the vertical axis of this graph might be: Volume (cm³). It migh also be liters, gallons, or other volume unit.

4) Although the horizontal axis is labeled, it does not indicate the units and the scale. So, you know neither if the temperature shown is celsius, (°C), farenheti (°F), kelvin (K), or rankine (R) (those are the four major scales of temperature), nor how much each division represent (1, 5, 10, 10, 50, 100?)
