Need a correct answer fastHow many moles of solute are contained in a 500.0 milliliter solution that has a concentration of 0.35 M?
Answers
Let x be the number of moles
Since the equation is moles/liters=molarity, change 500 mL to liters:
500.0 mL=0.5L
Divide:
x/0.5L = 0.35M
Cross multiply: x=0.35*0.5
x=0.175 moles

Slow receptors, which respond to stimuli over longer durations, are more likely to have a cumulative or 'summation' effect. The likelihood of this summation increases with the length of time required for the responses to decay. This mechanism plays a critical role in cognitive functions such as learning and memory.
Explanation:
In the context of neuronal signaling, when we speak about slow receptors, we are referring to those that respond to stimuli at a slower pace, often due to a longer duration of transmitter binding, and therefore have a higher likelihood of summation compared to the fast receptors.
The concept of summation refers to the cumulative effect of a series of neural responses that take time to diminish. In this case, the likelihood of summation is increased by the long period of time required for those responses to decay. Thus, the correct answer to your question would be option D) increased : long period. This is because the longer the responses take to decay, the more likely they are to accumulate or summate.
It is also important to note that this process significantly contributes to the cognitive functions of the brain, such as memory and learning by facilitating the creation of long term potentiation within neural networks.

%yield = 86.93%
Further explanation
Given
Reaction
CaCN₂+3H₂O=>CaCO₃+2NH₃
Required
The percent yield
Solution
mol CaCN₂(MW= 92 g/mol) :
= mass : MW
= 77 g : 92 g/mol
= 0.834
From equation, mol NH₃ :
= 2/1 x mol CaCN₂
= 2/1 x 0.834
= 1.668
Mass NH₃(theoretical):
= 1.668 mol x 18 g/mol
= 30.024 g
% yield = (actual/theoretical) x 100%
%yield = (26.1/30.024) x 100%
%yield = 86.93%

An appropriate hypothesis explaining the observation of distant galaxies moving away from each other, and that they do so more rapidly the further they are can be found in the Big Bang Theory. This theory suggests our universe began with a 'big bang' causing galaxies to move away from each other, a process which continues today.
Explanation:
Based on the observations mentioned, an appropriate hypothesis might involve the Big Bang Theory. This theory in physics and astronomy assumes that our universe started from a singularity - a very high-density and high-temperature state. The Big Bang Theory suggests that after the initial explosion, the galaxies began moving away from each other, a process which continues till today.
The farther a galaxy is from us, the faster it's receding, which is known as Hubble's Law. This observed phenomenon matches with the theory's premise, providing validating evidence for the Big Bang.
