Answer:

Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. They are most closely related to the terns and skimmers and only distantly related to auks, and even more distantly to waders. Until the 21st century, most gulls were placed in the genus

By what factor would the average kinetic energy of the particles by increased if the temperature of a substance was increased fr

natita [175]

Average kinetic energy of a particle :
0.5 mv^2 = kT/2
so the kinetic energy = kT/2
assuming the same value of K
T1 = -49 + 273 = 224
T2 = 287 + 273 = 560

E2 / E1 = kT2 / 2 / kT1 / 2
E2 / E1 = T2 / T1
E2 / E1 = 560 / 224 = 2.5
so the average kinetic energy of the particle increases by 2.5

2 icl + h2i2 + 2 hcl is first order in icl and second order in h2. Complete the rate law for this reaction in the box below. Use

OleMash [197]

2 ICl + H2 ----> I2 + 2 HCl

as given that rate is first order with respect to ICl and second order with respect to H2

The rate law will be

Rate = K [ICl] [ H2]^2

b) Given that K = 2.01 M^-2 s^-1

Concentrations are

[ICl] = 0.273 m and [H2] = 0.217 m

Therefore rate = 2.01 X (0.273)(0.217)^2 = 0.0258 M / s

The following steps refer to various stages in transmission at a chemical synapse. 1. Neurotransmitter binds with receptors asso

Furkat [3]

Answer:

3,2,5,1,4

Explanation:

A chemical synapse begins when an (3)action potential reaches the axon terminal depolarizing the membrane leading to the opening of the voltage-gated Na+ channels, this Na+ ions will then depolarize the presynaptic membrane, opening the voltage-gated Ca2+ channels. (2)Calcium ions then will initiate a cascade entering the neuron that will lead to the fusion of synaptic vesicles with the presynaptic membrane (5)causing the releasing of neurotransmitters into the synaptic cleft. (1)These neurotransmitter will diffuse across the synaptic place in order to bind to the receptors on the postsynaptic membrane, (4)particulary into the ligand-gated channels, opening them.
