The table provides the number of valence electrons for each of the two atoms that form an ionic and a covalent compound. Which o

f the following statements is true about one of the compounds? Compound C is ionic because both atoms are in need of electrons. Compound D is covalent because both atoms are in need of electrons. Compound D is ionic because one atom is in need of electrons and the other needs to lose electrons. Compound C is covalent because one atom is in need of electrons and the other needs to lose electrons.

Here we have to choose the correct statement among the given statements.

The true statement is-

Compound D is covalent because both atoms are in need of electrons.

The covalent compounds are those in which both the atom needs electrons and on the other hand ionic compounds are those in which one atom loose electron and other gain electron.

The atoms of the noble gas (except He) contains 8 electrons in their outermost shell. The high stability of the 8 electrons in the outermost shell of any atoms leads to the formation of covalent compound between two atoms.

Here the compound C posses two atoms atom 1 and atom 2 which posses 7 and 2 electrons respectively so atom 1 and atom 2 both needs electrons to get the 8 electrons in the outer shell. Thus it will be more ionic in nature.

The compound D posses two atoms having 6 and 5 valence electrons respectively. Thus atom 1 need 2 electrons and atom 2 needs 3 electrons to get the 8 electrons in the valence shell. so both the atom need electrons it will be covalent in nature.

<span>Because as you add energy levels, the electrons are drawn to the nucleus of the atoms giving them a lesser charge. Thus its atomic size also increases. </span>

At a certain temperature the rate of this reaction is first order in HI with a rate constant of :0.0632s
Shalnov [3]

Answer : The time taken for the reaction is, 28 s.

Explanation :

Expression for rate law for first order kinetics is given by :

k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}

where,

k = rate constant  = 0.0632

t = time taken for the process  = ?

[A_o] = initial amount or concentration of the reactant  = 1.28 M

[A] = amount or concentration left time 't' = 1.28\times \frac{17}{100}=0.2176M

Now put all the given values in above equation, we get:

0.0632=\frac{2.303}{t}\log\frac{1.28}{0.2176}

t=28s

Therefore, the time taken for the reaction is, 28 s.

Oxygen is killing us This isnt for science this is real talk the reason oxygen kills us because it damages our cells as we dont
siniylev [52]
I can tell you're not very educated because everyone knows that breathing pure oxygen for long periods of time can sometimes hurt us. Oxygen in lower levels, such as levels found in atmosphere are just right for us to breathe. Get a life and stop trying to scare young kids that just want help on their homework.

Hypochlorous acid decays in the presence of ultraviolet radiation. Assume that degradation occurs accord- ing to first-order kin
Dennis_Churaev [7]

Answer:

35.75 days

Explanation:

From the given information:

For first-order kinetics, the rate law can be expressed as:

\mathsf{In \dfrac{C}{C_o} = -kt}

Given that:

the rate degradation constant = 0.12 / day

current concentration C = 0.05 mg/L

initial concentration C₀ = 3.65 mg/L

\mathsf{In( \dfrac{0.05}{3.65})= -(0.12) t}

㏑(0.01369863014) = -(0.12) t

-4.29 = -(0.12)

t = -4.29/-0.12

t = 35.75 days
