Larutan penyangga dibuat dengan menggabungkan 50mL larutan H3PO4 1 M dan 50mL larutan NaOH 0,5. Berapakah pH dari larutan tersebut?
Both B and C are correct since they present identical options proposed in the question. Utilizing a lower gear in a vehicle aids in managing speed while descending a hill. It also helps preserve the brakes, which can overheat and lead to failures if overused on slopes. Shifting to a lower gear allows the engine to help reduce speed, although brakes may still be applied with less force. In this scenario, Stella should downshift to maintain control of her speed while descending the hill for safety.
Answer:
The value of Y is -10°.
Explanation:
For scale X, the freezing point is 40° and the boiling point is 120°.
The gap between the two endpoints for scale X = 120 - 40 = 80
For scale Y, the ice point and steam point are -30° and 130° correspondingly.
The difference between these two points for scale Y = 130 - (-30) = 160
Comparing both scales:
One unit in scale X is x
One unit in scale Y is y
Scale X consists of 80 divisions, while scale Y has 160
80x = 160y
x = 2y
50° on scale X equals 10x plus the freezing point of scale X
10 divisions in scale Y correspond to 20y
The reading on scale Y = the ice point of Y + 20y
= -30° + 20°
= -10°
The structure with the least oxygen is the vena cava. I hope this information is useful!
