Answer:
2.775 s.
Explanation:
<em>The half-life time for a first order reaction = 0.693 / k.</em>
Where, k is the rate constant of the reaction.
∴ The half-life time = <em>0.693 / k</em> = (0.693) / (0.271 s⁻¹) = 2.775 s.
Answer:
Explanation: he axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. ... The binding allows the nerve impulse to travel through the receiving neuron
Well, from what I can currently see, the only way the lines making a circle around the high pressure areas can indacate anything is nothing....because nothing is here. So technically I have fully answered your question.
I believe the answer is D
<span>The formula actual yield /
theoretical yield is used to calculate the percent yield of a reaction.
This value is a measure of how much product is produced relative to the what is
supposed to be produced. It can be associated with efficiency. However,
this value is specific for process which produces something like a
chemical reaction.
yield = (122 g / 156 g) x 100
</span><span>% yield = 78.21%</span>
