Two samples of matter differ in temperature by 20°C. What is the difference in temperature of these two samples using the Kelvin

anyanavicka [17]

Answer:

The difference is 293.15 Kelvin.

Explanation:

Given data:

Temperature difference of matter = 20°C

Temperature difference of matter in kelvin = ?

Solution;

Formula:

0°C +273.15

now we will put the values instead of 0.

20°C + 273.15 = 293.15 K

Thus, the temperature difference between two sample is 293.15 K.

In what type of reaction or process does heat flow into the system

SCORPION-xisa [38]

Answer: The correct answer is: " endothermic . "

______________________________________

Note: Heat flows into [heat may be absorbed within] an "endothermic" reaction or system

To the contrary, heat flows out  [heat may exit from or may be released from] an "exothermic" reaction or process.

Hint: Think of the "prefixes" of: "endothermic" and "exothermic" :

_____________________________________

1) endo- = "within" (as in "endothermic" —heat tends to be absorbed/"within"/"released within"/released within"/into" ;

2) exo- = " outwards"/"exit" (as in "exothermic") —heat tends to '"exit"/leave/escape from/"be released out of/form".

For the overall reaction below, which of the following is the correctly written rate law? Overall reaction: O3(g)+2NO2(g)→N2O5(g

zavuch27 [327]

Answer: $Rate=k[O_3][NO_2]^2$

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

$O_3(g)+NO_2(g)\rightarrow NO_3(g)+O_2(g)$ slow

$NO_3(g)+NO_2(g)\rightarrow N_2O_5(g)$ fast

To determine the net chemical equation, we will simply add the above two equations, we get:

$O_3(g)+2NO_2(g)\rightarrow N_2O_5(g)+O_2(g)$

$Rate=k[O_3][NO_2]^2$

Order with respect to $O_3$ is 1 and Order with respect to $NO_2$ is 2.

Thus the rate law will be: $Rate=k[O_3][NO_2]^2$
