An atom? The first guy sounds smart.

An atom. An atom has no charge. The number (and charge) of protons in atom's nucleus is balanced by the electrons orbiting the nucleus. If it had charge it would be called an ion.

Consider two bulbs seperated by a valce. Both bulbs are amintained at the same temperature. Assume that when the valve between t

Juliette [100K]

Answer:

The pressure is $P_f = 0.93 \ atm$

Explanation:

From the question we are told that

The volume of Ne is $V_N = 2.50 \ L$

The volume of CO is $V_C = 2.00 \ L$

The pressure of $Ne$ is $P_N = 1.09 \ atm$

The pressure of CO is $P_C = 0.773 \ atm$

The number of moles of Ne present is evaluated using the ideal gas equation as

$n_N = \frac{P_N * V_N}{R T}$

=> $n_N = \frac{1.09 * 2.50 }{R T} = \frac{2.725}{RT}$

The number of moles of CO present is evaluated using the ideal gas equation as

$n_N = \frac{P_C * V_C}{R T}$

=> $n_N = \frac{0.73 * 2.00 }{R T} = \frac{1.46}{RT}$

The total number of moles of gas present is evaluated as

$n_T = n_N + n_C$

$n_T = \frac{2.725}{RT} + \frac{1.46}{RT}$

$n_T = \frac{4.185}{RT}$

The total volume of gas present when valve is opened is mathematically represented as

$V_T = V_N + V_C$

=> $V_T = 2.50 + 2.00 = 4.50 \ L$

From the ideal gas equation the final pressure inside the system is mathematically represented as

$P_f = \frac{n_T * RT }{ V_T}$

=> $P_f = \frac{[\frac{4.185}{RT} ] * RT }{ 4.50}$

=> $P_f = 0.93 \ atm$

Draw a mechanism for the reaction of methanol with sodium amide. In the box to the left, draw any necessary curved arrows. Show

Greeley [361]

Answer:

See explanation

Explanation:

When sodamide reacts with methanol, the following equilibrium is set up;

CH3OH(aq) + NH2-(aq) ⇄ CH3O-(aq) + NH3(aq)

In the reaction, the sodamide acts as a base that abstracts a proton from methanol to yield the conjugate base of methanol which is the methoxide ion.

The forward reaction is favoured at equilibrium.

What volume in kiloliters will a sample of Bay water occupy if it has a volume of 125 ml?

Mamont248 [21]

This question is basically asking us to convert the volume from mL to kL.

We can do this by setting up a multiplication problem and cancelling out units:

$\frac{125mL}{1}* \frac{1L}{1000mL} * \frac{1kL}{1000L} =1.25* 10^{-4}kL$

So now we know that the Bay water will occupy 1.25x10^-4 kL.

The process of removal of oxygen in a chemical reaction is called?

solmaris [256]

Answer:

Deoxygenation

Explanation:

This is when an oxygen atom is taken out of something, example when sand turns black in the mud flats. The sand is being deoxygenated by the ghost shrimp. Pulling oxygen from it.
