Answer:
the pressure of the gas in torr is 2280 torr
Explanation:
The pressure of a gas in torr can be calculated by converting its pressure in kPa to atmospheres and then converting the atmospheric pressure to torr.
One atmosphere is equal to 101.325 kPa. Therefore, the pressure of the gas in atmospheres is 305 kPa / 101.325 kPa/atm = 3.00 atm.
One torr is equal to 1/760 of an atmosphere. Therefore, the pressure of the gas in torr is 3.00 atm * 760 torr/atm = 2280 torr.
Therefore, the pressure of the gas in torr is 2280 torr
<span>Molds are created to achieve a
specific design of a material. These materials either came from a process of
having a higher or lower temperature. Therefore, the molder must have thermal
resistant properties. Low melting points means that the material to be shaped
came from a cooler process. Wood and metal have higher thermal conductivity and
therefore can easily be cooled. The wax can turn really hard and can be
unbreakable when present in colder materials due to the lipids present in it. Clay
however can become a mold because of its low melting point.</span>
Answer:
B). The equivalence point is where the amount of acid equals the amount of base during any add-base titration.
Explanation:
Equivalence point -
During the process of titration of the neutralization reaction , like acid - base reaction .
In the titration process , the equivalence point is the point , when the amount of acid is equal to the amount of base .
In indicator used for th process is pH sensitive ,
It is not always necessary to have pH = 7 at the equivalence point ,
The titration curve is plotted for the pH v/s base .
Hence , from the given options , the correct statement is ( B ) .
