Answer:
0.5 atm is equal to 380mmHg.
Explanation:
For every 1 atm, it is equal to 760mmHg.
Therefore, 0.5 atm is 760/2, which is 380mmHg.
I JATW THAT I NEED TO ANSWER TO ASK
Answer:
C
Explanation:
If the enthalpy change (i.e. Δ<em>H</em>) of a reaction is negative, then the reaction releases heat and is hence exothermic.
Hence, our answer is C.
Conversely, if Δ<em>H</em> is positive, the reaction absorbs heat and is endothermic.
Δ<em>H</em> tells us nothing about the speed of the reaction.
While Δ<em>H</em> influences free-energy change (Δ<em>G</em> = Δ<em>H</em> - <em>T</em>Δ<em>S</em>), we cannot predict the sign of Δ<em>G</em> given only Δ<em>H </em>(recall that a reaction is spontaneous if Δ<em>G</em> < 0).
Well i suspect it to be water-- yes water btw the answers are 1B 2B 3D 4B 5B 100% Correct
B Silver Chloride
when you mix AgNO3- and NaCl- they make AgCl which is insoluble and settle to the bottom of the test tube, and NaNO3 which remains as a liquid solution
