What happens if you shake a closed bottle of water and vinegar and let it settle for 5 minutes?
If you mix water and vinegar (acetic acid) it forms a homogeneous solution (mixture). Shaking it and letting it stand for 5 minutes will not change the appearance or the composition of the solution. So, basically noting happens.
How might you separate a solution of salt water?
You can pour the solution into a tray and set in in sun light and leave it for several minutes.
What does dd mm mmm stands for in latitude and longitude?
Latitude and longitude are angles. Like other angles, they can be written in a few different ways: Examples: -- degrees and decimals of a degree -- degrees, minutes, and decimals of a minute -- degrees, minutes, seconds, and decimals of a second When you're filling in an angle on a paper form or on a computer, they'll show you how they want you to write the angle. "dd mm.mmm" means "dd" . . . two digits for the number of degrees "mm.mmm" . . . two digits for the whole minutes, and three decimal places for the fraction of minutes.
What is the difference between latitude and longitude extent of India?
The latitude extent of India is approximately 8 degrees 4 minutes N to 37 degrees 6 minutes N. The longitude extent of India is approximately 68 degrees 7 minutes E to 97 degrees 25 minutes E. The latitude represents how far north or south a location is from the equator, while the longitude represents how far east or west a location is from the Prime Meridian.

Which diagram best represents the appearance of the cell after it has been placed in a 15 salt solution for two minutes?
Diagram A, as the cell will have likely shrunk due to water leaving the cell to dilute the higher concentration of salt outside of the cell, causing it to lose water and shrink.
How many minutes are in 2 thirds of an hour on a diagram?
There are 40 minutes in 2/3 hour, diagram or not.
What happens if you shake a closed bottle of water and vinegar and let it settle for 5 minutes?
If you mix water and vinegar (acetic acid) it forms a homogeneous solution (mixture). Shaking it and letting it stand for 5 minutes will not change the appearance or the composition of the solution. So, basically noting happens.
What fraction of a day is 80 minutes?
To find what fraction of a day 80 minutes represents, we first note that a day has 1,440 minutes (24 hours × 60 minutes). Therefore, the fraction of a day that 80 minutes represents is 80/1440, which simplifies to 1/18. Thus, 80 minutes is 1/18 of a day.
How much is 30 minutes in a hour?
Thirty minutes is half of an hour. Since an hour consists of 60 minutes, 30 minutes represents 50% of that total.
Which of these values represents the longest period of time is it 35000 milliseconds or 350 seconds or 35 minutes or 0.35 hours?
35 minutes represents the longest period of time among the options given.
What do minutes stands for in latitude?
Minutes (and seconds) are finer subdivisions of degrees. There are 60 minutes in a degree, so a minute represents 1/60th of a degree.
When does Penny Marko make her first appearance in Spider-Man 3?
Penny Marko makes her first appearance a few minutes from Marko's first appearance and before he transforms into the Sandman.
How long will it take drive 600 miles at 55 mph?
This requires a bit of physics, which can be done:d represents distance, m represents miles, v represents velocity and trepresents time. and mph represents miles per hourd = v * tt = d/v = 600 m/55 mph = 10.9 h which converts to (9/10)h in which there are 60 minutes in an hour, so h = 60, meaning that (9/10)h = (9/10)(60) = 9*6 since 60/10 = 6 and it factors, so 9 * 6 = 54 minutes, so the solution is 10 h, 54 min or 10 hours and 54 minutes in simplified form.
Why did the penny turn silver after a few minutes in the hot solution?
The hot solution likely removed the copper oxide layer on the penny, revealing the silver-colored zinc underneath. Heating caused a chemical reaction that removed the tarnished layer on the penny, giving it a shiny appearance.
What fraction of an hour represents 45 minutes?
It is 45/60, which can be simplified, if required.
What fraction of an hour represents 50 minutes?
It is 50/60 which can be simplified, if required.
