Answer:

Molarity = 0.5 M

Osmolarity = 0.5 x 2 = 1 Osmpl.

Molecules of Cl2 = 6.02 x 10^{23} / 4= 1.505 x 10^{23} no. of molecules

Explanation:

If we add half mole in 1L volume than molarity will obviously be 0.5 M.

The osmolarity is molarity multiplies by number of dissociates of solute that for CaCl2 are 2. So, 2 x 0.5 = 1

Half will be molecules of Ca and half will be of Cl2 for 0.5M.

A) what is hydrogen's carrying capacity? <br> b) what is lithium’s carrying capacity?
sladkih [1.3K]

Answer:

A)Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C.

B) carrying capacity of the lithium reserve will reach 10 million EV and 90 billion CE's RLBs for 50% recycling of lithium-containing waste, and 15 million EV and 150 billion CE's RLBs for 90% recycling.

Which of the following is the best name for a compound made from nitrogen and oxygen? (N2O3) nitrogen oxide nitrogen II oxide ni
sergejj [24]

The best name for the compound is DINITROGEN TRIOXIDE.

Each chemical compound is always represented by a chemical symbol, which shows the ratio at which each atom of the elements of the compound are combine together and this is often used in naming the compound. Looking at the compound given in the question, the compound is made up of two atoms of nitrogen and three atoms of oxygen and this fact was used in naming the compound. In naming chemical compounds, 'Di' stands for 2 while 'Tri' stands for 3. Since there are two nitrogen and three oxygen atoms in the compound, that was why it was named dinitrogen trioxide.
