Chromium nitride
Chromium nitride is a chemical compound of chromium and nitrogen with the formula CrN.
Answer:
In engineering and science the common stand is two places.
For example if you get a calculation of 4.567 round up and give the result of 4.57
Greenhouse gases act to <u>increase</u> temperatures by <u>absorbing</u> thermal infrared radiation.
We have already learned that Earth's atmosphere is composed often of nitrogen and oxygen. Those gases are transparent to incoming solar radiation. they may be also transparent to outgoing infrared radiation, which means that they do not take in or emit sun or infrared radiation.
The multiplied quantities of greenhouse gases human sports are adding to the environment have dissatisfied the balance that has been in location for the reason that ceases of the closing ice age, including greater greenhouse gases decreases the amount of infrared radiation energy leaving the atmosphere.
Greenhouse gases inside the ecosystem time and again absorb and re-radiate infrared radiation (warmth). strength radiated from Earth's surface as warmth, or infrared radiation is absorbed and re-radiated by using greenhouse gases, impeding the loss of warmth from our surroundings to area.

Answer:
81.26% is the percent yield
Explanation:
Based on the reaction:
CaCl₂ + Na₂CO₃ → 2NaCl + CaCO₃
<em>Where 1 mole of CaCl₂ in excess of sodium carbonate produces 1 mole of calcium carbonate.</em>
<em />
To solve this question we must find the moles of CaCl2 added = Moles CaCO₃ produced (Theoretical yield). The percent yield is:
Actual yield (0.366g) / Theoretical yield * 100
<em>Moles CaCl₂ = Moles CaCO₃:</em>
0.0500L * (0.0900moles / L) = 0.00450 moles of CaCO₃
<em>Theoretical mass -Molar mass CaCO₃ = 100.09g/mol-:</em>
0.00450 moles of CaCO₃ * (100.09g / mol) = 0.450g of CaCO₃
Percent yield = 0.366g / 0.450g * 100
81.26% is the percent yield
Li+ has a smaller ionic radius than K+
and smaller molecules have more collisions/interactions between each other
<h3>What is ion-solvent interaction ?</h3>
In the case of ion-solvent interactions, the state in which the interac-tions exist is an obvious one; it is the situation in which ions are inside the solvent.
- Ions are charged particles, and charges interact with other charges. So there will also be ion-ion, as well as ion-solvent, interactions in the solution.
- In the process of solvation, ions are surrounded by a concentric shell of solvent. Solvation is the process of reorganizing solvent and solute molecules into solvation complexes.
