2 mg + 02–> 2Mg0 reaction type?

In the Haber Process, hydrogen (H2) and nitrogen (N2) react to produce

lesya692 [45]

Answer:

Mass stays the same because no matter is created or destroyed.

Explanation:

Regardless of what chemical reaction we have, in each case the law of mass conservation applies. The law of mass conservation states that the total mass of a reaction mixture is kept constant, as mass cannot be created or destroyed.

In this specific reaction, the total mass of the reactants should be equal to the total mass of the products when the reaction is complete.

In other words, if we add the mass of hydrogen to the mass of nitrogen, when the reaction is compete, assuming no reagent in excess, this should be equal to the mass of ammonia formed.

Increasing the temperature of gas in a container that cannot expand is a way to _______. decrease the volume of the gas decrease

alex41 [277]

Answer:

Increase the pressure of the gas

Explanation:

According to the Pressure law, for a fixed mass of gas, at a constant volume (V), the pressure (P) is directly proportional to the absolute temperature (T).

From the kinetic molecular theory, gases are composed of particles which are in constant motion, colliding with themselves as well as with the walls of their container.

When the temperature of these gas molecules is increased, the molecules acquire more kinetic energy and the rate of collisions increases. Since the container cannot expand, the increase in pressure is due to the increase in collisions between the molecules of the gas as well as with the walls of their container.

A buffer is prepared by adding 300. 0 ml of 2. 0 mnaoh to 500. 0 ml of 2. 0 mch3cooh. what is the ph of this buffer? ka= 1. 8 10

Anton [14]

The Henderson-Hasselbalch equation can be used to determine the pH of the buffer from the pKa value. The pH of the buffer will be 4.75.

<h3>What is the Henderson-Hasselbalch equation?</h3>

Henderson-Hasselbalch equation is used to determine the value of pH of the buffer with the help of the acid disassociation constant.

Given,

Acid disassociation constant (ka) = 1. 8 10⁻⁵

Concentration of NaOH = 2.0 M

Concentration of CH₃COOH = 2.0 M

pKa value is calculated as,

pKa = -log Ka

pKa = - log (1. 8 x 10⁻⁵)

Substituting the value of pKa in the Henderson-Hasselbalch equation as

pH = - log (1. 8 x 10⁻⁵) + log [2.0] ÷ [2.0]

pH = - log (1. 8 x 10⁻⁵) + log [1]

= 4.745 + 0

= 4.75

Therefore, 4.75 is the pH of the buffer.

Would fluorine form a positive or a negative ion?

IceJOKER [234]

It would form a negative ion... it lacks 1 e in its valence shell., it is easier for F to accept an e than to shed all existing 7.
e= electron
