Effervescence of h2 gas will be produced which burns off a glowing split with a pop sound when hcl reacts with a base
Combustion:
The saturated hydrocarbons are relatively inert except at high temperatures. Combustion is one of the more important chemical reactions of the alkanes.
Alkanes have the general formula of CnH2n+2. For example, an alkane with 6 carbon atoms (n = 6) would have a formula of C6H2·6+2 or C6H14. Structurally C6H14 would be shown as:
Answer:
Explanation:
B because it has a lower activation energy
Answer:
The correct answer is
B.action potential; sodium
Explanation:
Action potential
Nerve action potentials are initiated and propagated in an all or nothing fashion. The all-or nothing action potential is initiated when the membrane potential threshold value is reached
Sodium
Voltage-gated Na⁺ ions membrane channels open enabling an influx of sodium ions to rapidly enter the cell, raising the membrane potential up to +40 mV
Depolarization in the neuron is based ion exchange channels opening to allow the rapid influx of sodium ions (Na⁺) and the efflux of potassium ions (K⁺)
The neuronal responds rapidly and for short periods to the activation of an ion channel receptor by a drug or natural neurotransmitter is rapid rel
