Answer:

Explanation:

C2H4 + O2 → CO2 + H2O

eqn is unbalanced - balancing by counting no. of C n H atoms

C=2 n H=4 in one C2H4

so the reaction will form two CO2 + two H2O

counting no. of O atoms: 2*2 + 2*1

=4+2

Carbon has a neutral overall charge, an atomic mass of about 12 and an atomic number of 6. How many electrons does carbon have?
Artist 52 [7]
For the atom to be neutral, it must have the same number of electrons and protons. The aromic number indicates the number of protons. Since Carbon has 6 protons, it would have to have 6 electrons for it to be neutral

reddit The amount of NE released by sympathetic nerve terminals will be most strongly influenced by a change in which of the fol
erastovalidia [21]

Answer: Extracellular [Ca2+]

Explanation:

The sensitivity and density of the alpha receptors serve to <em>enhance the response to the release of</em> <em>norepinephrine (NE)</em> . However, they do not exert a strong influence as the concentration of calcium ions on the amount of <em>norepinephrine (NE)</em> released by sympathic nerve terminals.

The release of neurotransmitters depends more on either an external or internal stimulus.This results in an action potential which on reaching a nerve terminal, results in the opening of Ca²⁺ channels in the neuronal membrane. Because the extracellular concentration of Ca²⁺ is greater than the intracellular Ca²⁺ concentration, Ca²⁺ flows into the nerve terminal. This triggers a series of events that cause the vesicles containing <em>norepinephrine (NE)</em> to fuse with the plasma membrane and release <em>norepinephrine (NE)</em> into the synapse. The higher the action potential, the higher the Ca²⁺ flow into the terminals resulting in higher amount of <em>norepinephrine (NE)</em> into the synapse, and vice versa.

Catechol-O-methyltransferase (COMT) is one of several enzymes that degrade catecholamines such as dopamine, epinephrine, and norepinephrine. It serves a regulatory purpose to lower the concentration of norepinephrine upon its release from nerve terminals.

The equilibrium constant, Kc, for the reaction N2O4(g)⇌2NO2(g) is 5.0×10−3. If the equilibrium mixture contains [NO2] = 0.050 M
Sergeu [11.5K]

Answer:

0.50 M is the molar concentration of N_2O_4.

Explanation:

The equilibrium constant of the reaction = K_c=5.0\times 10^{-3}

N_2O_4(g)\rightleftharpoons 2NO_2(g)

Equilibrium concentration of NO_2 = 0.050 M

[NO_2]=0.050 M

Equilibrium concentration of N_2O_4 = ?

[N_2O_4]= x

The equilibrium constant of the reaction is given aSL:

K_c=\frac{[NO_2]^2}{[N_2O_4]}

K_c=\frac{(0.050 M)^2}{x}=5.0\times 10^{-3}

x = 0.50 M

0.50 M is the molar concentration of N_2O_4.
