Answer:
x axis and y axis divide the coordinate plane into four quadrants.
Step-by-step explanation:
If one coordinate is zero, then the point is located on the x-axis or the y-axis. If y coordinate is zero, then the point is located on the y-axis. If both coordinates are zero, then the point represents the origin.
The sequence is not geometric because there is no common difference or common ratio between each term. it’s also not an Arithmetic Sequence
Answer:
26.35 °C
Step-by-step explanation:
To find, how much the maximum daily temperature is higher than that of minimum, we'll subtract both.
=> 21.85 - (-4.7)
=> 21.85 + 4.7
=> 26.35 °C
The reaction is missing and it's ;
N2H4 + H2 ---> 2NH3
It asks for the total pressure too.
Answer:
A) Rate of change for NH3 = 152 torr/h
B) The total pressure in the vessel will remain the same.
Step-by-step explanation:
N2H4 + H2 ---> 2NH3
1 mole of N2H4 yields 2 moles of NH3.
From the question, the rate given for N2H4 is 76 torr/h.
Thus, The rate of change for NH3 will be = 2 x 76 = 152 torr/h
Now, on the reaction side, 1 mole of N2H4 reacts with 1 mole of H2. So we have 2 moles on the left hand side.
While on the product side, 2 moles of NH3 are produced.
So the total pressure will remain the same because for every 2 moles on the reaction side, 2 moles are gotten on the product side.
