What is the mass of 22.4 L of H2 at STP?
Vanyuwa [196]

A. 1.01 is the right answer

Since

The formula is Pv= nRT

P=1 atm

V= 22.4 L

N= x

r= 0.0821

t = 273 k (bc it’s standard temperature)

So (1)(22.4)=(x)(0.0821)(273)

X= 1.001

The reaction of nitrogen gas and oxygen gas to form nitrogen monoxide gas is shown below. If the measured concentrations of all
Anettt [7]

Answer:

The forward reaction is occurring at a faster rate than the reverse reaction.

Explanation:

Reaction quotient (Q) of the given reaction is -

                                     Q=\frac{[NO]^{2}}{[N_{2}][O_{2}]}

where [NO], [N_{2}] and [O_{2}] represents concentrations of respective species at a certain time.

Here [N_{2}]= 0.80 M, [O_{2}]= 0.050 M and [NO] = 0.10 M

So, Q=\frac{(0.10)^{2}}{(0.80)\times (0.050)}=2

Hence Q> K

It means that forward reaction is faster than reverse reaction at that point. Because then only concentration of NO is higher than concentrations of [N_{2}] and [O_{2}] which makes Q higher than K.

When two carbon atoms are joined by a double bond, how many electron pairs are shared between the two carbons
NikAS [45]

Answer:

Two (2) electron pairs

Explanation:

The sharing of electron pairs by atoms forms a type of bond called COVALENT bond. Atoms that form covalent bonding (share electrons) do so in order to fill their outermost electron shells, hence, gain chemical stability.

However, when two atoms like carbon share TWO PAIRS of electrons with each other, a DOUBLE BOND is formed. An example is the double bond formed in Ethylene (2HC=CH2). A total of four valence electrons (a pair from each carbon) are shared between the two carbon atoms.
