Answer:

Ethyl propionate reacts with ammonia it gives ethanamide and ethanol.

Explanation:

When an ester reacts with ammonia to give acid amide and an alcohol. This can be expressed in the form of chemical reaction :

$R-(CO)-OR'+NH_3\rightarrow R-(CO)-NH_2+R'OH$

Ethyl propionate is an ethyl ester of propionic acid.

Ethyl propionate = $CH_3-CH_2(CO)-OCH_2CH_3$

So, when ethyl propionate reacts with ammonia it gives ethanamide and ethanol.

$CH_3-CH_2(CO)-OCH_2CH_3+NH_3\rightarrow$

$CH_3-CH_2-(CO)-NH_2+CH_3-CH_2-OH$

This is an incomplete question, here is a complete question.

Manganese commonly occurs in nature as a mineral. The extraction of manganese from the carbonite mineral rhodochrosite, involves a two-step process. In the first step, manganese (II) carbonate and oxygen react to form manganese (IV) oxide and carbon dioxide:

$2MnCO_3(s)+O_2(g)\rightarrow 2MnO_2(s)+2CO_2(g)$

In the second step, manganese (IV) oxide and aluminum react to form manganese and aluminum oxide:

$3MnO_2(s)+4Al(s)\rightarrow 3Mn(s)+2Al_2O_3(s)$

Write the net chemical equation for the production of manganese from manganese (II) carbonate, oxygen and aluminum. Be sure your equation is balanced.

Answer : The net chemical equation for the production of manganese is:

$6MnCO_3(s)+3O_2(g)+8Al(s)\rightarrow 6CO_2(g)+6Mn(s)+4Al_2O_3(s)$

Explanation :

The given two chemical reactions are:

(1) $2MnCO_3(s)+O_2(g)\rightarrow 2MnO_2(s)+2CO_2(g)$

(2) $3MnO_2(s)+4Al(s)\rightarrow 3Mn(s)+2Al_2O_3(s)$

First we are multiplying reaction 1 by 3, and reaction 2 by 2, we get:

(1)

(2) $6MnO_2(s)+8Al(s)\rightarrow 6Mn(s)+4Al_2O_3(s)$

Now we are adding both the reactions, we get the overall chemical reaction.

$6MnCO_3(s)+3O_2(g)+6MnO_2(s)+8Al(s)\rightarrow 6MnO_2(s)+6CO_2(g)+6Mn(s)+4Al_2O_3(s)$

The $MnO_2$ is common on both side, by cancelling it, we get:

The net chemical equation for the production of manganese is:

$6MnCO_3(s)+3O_2(g)+8Al(s)\rightarrow 6CO_2(g)+6Mn(s)+4Al_2O_3(s)$

Which statement accurately describes how electrical power and voltage are

neonofarm [45]

Answer: B

Explanation:

According to Ohm's Law, the answer is B.

Ohm's Law states that power is equal to volume x current.

If volume x current equals power, that means they are both 50% of power.

Ohm's Law:

power = voltage x current

current = voltage x power

voltage = power x current

¿como afecta la<br> temperatura el <br> volumen de un gas?

Oxana [17]

Lo afect porque cuando la temperature aumenta, el volumen aumentará, luego, cuando we mantiene la presión, es constante. Calentar el gas aumenta la emergía cinética we law partículas, lo que have que el gas se expanda.

Espero que esto ayude :)
