When the pressure that a gas exerts on a sealed container changes from 22.5 psi to psi the temperature changes from 110 c to 65.
ad-work [718]
Gay- Lussacs law states that the pressure of a gas is directly proportional to temperature for a fixed amount of gas at constant volume.
therefore P/T = k
where P - pressure , T - temperature and k - constant 
\frac{P1}{T1} =  \frac{P2}{T2}

parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
T1 - temperature in kelvin - 110 °C + 273 = 383 K
T2 - 65.0 °C + 273 = 338 K
substituting these values in the equation 

\frac{22.5 psi}{383 K} =  \frac{P}{338K}
P = 19.9 psi 
new pressure is 19.9 psi

what’s the chemical equation for production of potassium vapor and molten sodium chloride from molten potassium chloride and mol
elena-14-01-66 [18.8K]

Answer:

\huge\boxed{\sf KCl_{(aq)}+Na_{(aq)} \longrightarrow K_{(l)}+NaCl_{(aq)}}

Explanation:

<u>Chemical formulas for every compound:</u>

Potassium vapor => K_{(l)

Molten soldium chloride => NaCl_{(aq)}

Molten Potassium chloride => KCl_{(aq)}

Molten Sodium Metal => Na_{(aq)}

<u>The reaction will be as follows:</u>

KCl_{(aq)}+Na_{(aq)} \longrightarrow K_{(l)}+NaCl_{(aq)}

This reaction is usually called displacement reaction in which an element displaces another element of a compund.

Identify the type of energy involved in each step:
77julia77 [94]

Answer:

a. Electric Energy

b. Light Energy

c. Thermal Energy

Explanation:

a. When a lamp is turned on by means of a switch, electric energy is usually used, since that is the form of energy that is generated when there is a potential difference between two points, which allows to establish an electric current, that electric current travels through the wires up to the bulb of the lamp

b. In this case a case of light energy is presented since that is the energy transported by the light and that is manifested on the matter in different ways, one of them is to remove the electrons from the metals. This is what usually happens in some types of light bulbs, that when the displacement of the electrons is promoted, a beam of light is generated.

c. The last case is a case of thermal energy, since this energy is that expressed as the total kinetic energy resulting from the random movements of atoms and molecules. This was what could happen in case b, when the beam of light was generated. This energy is released in the form of heat, and may present high temperatures.

Discuss FOUR ways in which one's acceptance of responsibility can influence
andrew11 [14]

Answer:

being responsible is owing up to the possible

consequences of your decision whether it was right or wrong.

communication is a two way process in which there is a messenger and receiver

one of the ways by which a person could be responsible is by saying 'I'

in all the things he would say, instead of 'we'

for example , " We don't like the way you acted a while ago " , change it to i don't like tye way you acted a while ago.

here u r establishing ownership on the things you want to say to the person
