Answer and Explanation:

In most of the cases a neurotransmitters is discharged based on what's known as the axon terminal after an activity potential has arrived at the neurotransmitter, a spot where neurons can transmit sign to one another. These cells contain receptors where the synapses can tie and trigger changes in the cells.

Neurotransmitters are put away in synaptic vesicles, bunched near the cell film at the axon terminal of the presynaptic neuron. Synapses are discharged into and diffuse over the synaptic split, where they tie to explicit receptors on the film of the postsynaptic neuron.

Elements x and y form 2 binary compounds. In the first 14.0 g of x combines with 3.0 g of y. In the second, 7.00 g of x combine

Roman55 [17]

second compound

Let molar mass of x is = X

Let molar mass of y is = Y

Moles of x in second compound = Mass / molar mass = 7 / X

Moles of y in second compound = Mass / molar mass = 4.5 / Y

For second compound

7 / X : 4.5/ Y = 1:1

Therefore

X / Y = 7/4.5

Y / X = 4.5/ 7

The mass of x in first compound = 14g

moles of x in first compound = 14/X

Mass of y in first compound = 3

moles of y in first compound = 3 / Y

14 / X : 3/ Y = 14Y / 3X = 14 X 4.5 / 3 X 7 = 3 :1

Thus molar ratio in first compound = moles of x / Moles of y = 3:2

Formula = x3y

You discover a piece of jewelry that you think might be made of silver. You place the item on a balance and determine that it ha

Amanda [17]

No, this item is not made of pure silver because if it has been made from pure silver that it would have displaced only 1.16cm³ of water but due to the addition of some other low-density element it displaces 1.9cm³ of water.

For pure silver

density of pure silver is = 10.49 g/cm³

mass of silver = 12.2 gram

since, density = mass/volume

volume = mass/density

= 12.2/10.49 cm³

= 1.16 cm³

But the actual displaced water is 1.9cm³, which means some other element of lower density has been added.

Therefore, it is clear that the given jewelry is not made of pure silver.

When magnesium carbonate, MgCO2, reacts with nitric acid, HNO3, it forms magnesium nitrate, Mg(NO3)2, and carbonic acid, H2CO3.

schepotkina [342]

I think the correct answer among the choices listed above is option C. The two type of reaction taking place in the process are double-replacement reaction and decomposition reaction. The double-replacement reaction is the reaction between magnesium carbonate and nitric acid while the decomposition is the breaking down of the carbonic acid into water and CO2.
