Answer:
It should b KNO3
Explanation:
one Potassium (K) and three Nitrite (NO3)
Answer:
False
Explanation:
The slope of a velocity-time graph gives acceleration. Acceleration can be defined as the change in velocity with time.
A slope denotes the gradient of line. It takes into consideration the changes on both y and x axis. The ratio of the changes gives the slope.
On a velocity-time graph, the y-axis is the velocity and the x-axis is time. The change in velocity with time gives acceleration.
The slope of an acceleration
-time graph is not velocity.
Answer:
The zeros in front of the 3 show where the decimal is. Then start counting at the 3 to the right. There are 6 sig figs.
Explanation:
Answer: pOH = 4.68
Explanation:
pOH = 14 - pH
pH = - Log [H+]
= - Log [4.8 x 10^-10]
= -(-9.32)
pH =+9.32
Therefore, pOH= 14 - 9.32
= 4.68
Qualitative because it changed its colour not its quantity :)
