Answer:
B) Either speed or direction can change
There are only two ways for you to accelerate: change your speed or change your direction—or change both. If you're not changing your speed and you're not changing your direction, then you simply cannot be accelerating—no matter how fast you're going.
Answer:
storage solution , deionized water, stabilizes
Explanation:
A pH meter is a scientific device or instrument that is used to measure the pH of a given aqueous solution thereby determining the nature of the solution whether it is acidic or basic or neutral.
While using the pH meter or taking the measurement using the pH meter --
- it should be kept in a storage solution for effective working.
- Before using the device, it is rinsed with a deionized water and pat dry.
- Record the measurements when the pH meter stabilizes.
Answer:
Only dichloromethane will be present as bottom layer and other given solvents will be present as top layer in an aqueous extraction.
Explanation:
Whether the aqueous layer would be present on top or bottom, is decided by densities of the solvent.
Solvent which is less denser than water will be present as top layer in aqueous extraction and solvent which is more denser than water will be present as bottom layer.
Therefore,
a) Methanol is less dense than water, hence will be present as top layer in an aqueous layer.
b) Hexane is less dense than water, hence will be present as top layer in an aqueous layer.
c) Benzene is less dense than water, hence will be present as top layer in an aqueous extraction.
d) dichloromethane is more dense than water and hence will be present as bottom layer in aqueous extraction
e) diethyl ether is less dense and will be present as top layer in an aqueous layer.
So, only dichloromethane will be present as bottom layer and other given solvents will be present as top layer in an aqueous extraction.
Answer:
Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. ... Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

Your Welcome:))
Yes, it does matter... you pour Acid into water and not water in Acid... because when you pour water in acid it may splash out
