Answer:
The correct answer will be " RbF > RbCl > RbBr > Rbl".
Explanation:
The size of the given ions will be:
<u>RbCl:</u>
⇒ 689kJ/mol
<u>RbBr:</u>
⇒ 660kJ/mol
<u>Rbl:</u>
⇒ 630kJ/mol
<u>RbF:</u>
⇒ 785kJ/mol
Now according to the size, the arrangement will be:
⇒ (785kJ/mol) > (689kJ/mol) > (660kJ/mol) >(630kJ/mol)
⇒ RbF > RbCl > RbBr > Rbl
The bond among all opposite charging ions seems to be strongest whenever the ions were indeed small.
Missing question: <span>A 5.00 L sample of O2 at a given temperature and pressure contains a 1.08x10^23 molecules. How many molecules would be contained in each of the following at the same temperature and pressure? </span>
a) 5.00 L H2.
<span>b) 5.00 L CO2.
Use </span>Avogadro's Law: The Volume Amount Law: <span>equal </span>volumes<span> of all gases, at the same temperature and pressure, have the same </span>number<span> of molecules. Because hydrogen and carbon(IV) oxide are gases, number of molecules are the same as number of oxygen molecules, so:
a) N(H</span>₂) = 1.08·10²³.
b) N(CO₂) = 1.08·10²³
I think the correct answer from the choices listed above is option A. The additional piece of information needed to determine the molecular formula would be percent composition of carbon. A molecular formula is <span>a formula that gives the number of atoms of each of the elements present in one molecule of a specific compound.</span>
Answer:
Explanation:
A covalent compound is made when two or more nonmetal atoms bond by sharing valence electrons. The shared valence electrons between two nonmetal atoms is called a covalent bond. Covalent bonds are formed when two atoms begin sharing electrons
Answer:
Venus
Explanation:
its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth.
