Answer:
opposite
Explanation:
negative charged objects move away from each other
sorry if I'm wrong
<u>Answer:</u>
<em>Latest take an example to understand how </em><em>balancing of chemical reaction</em><em> is done that is assuming the reaction between iron as well as </em><em>oxygen which reacts to form rust.</em>
<u>Explanation:</u>
For this we would simply right the reactant and product that is expected. Then we would see the number of molecules of each element present on either side.
If in the reaction the element’s molecules are the same on both sides then the reaction would be correct and if not then we have to apply trial and error method to balance the equation such that the number of molecules of each element is equal on both sides of the reaction.
<span>For addition and subtraction you round to decimal places.
Round the number so that it has the same number of decimal places as the number in your data that has the least number of decimal places.
9 cm + 2.8 cm = 11.8 cm
the 9 has no decimal places so
= 12 cm
(this is rounded to 0 decimal places.)

Answer: A) Storing experimental samples
Explanation:
It is a common piece of laboratory glassware that can be made of glass or plastic and is opened at the top and closed at the bottom.
It cannot be used for measurements because there is no graduation indicating the volume.
Althought it can contain extra chemicals left over from an experiment, it is not the main proposal of the glassware that is to store samples.
It cannot be used in a microscope and the object for that is a microscope slide.
Rayleigh waves (which are a type of surface wave) produce the largest amplitude and so most severe ground movements during earthquakes.
Surface waves produce the most severe ground movements. They produce movements similar to waves in the water, where the water's particles move in a pattern that is almost circular. They move more slowly then P waves or S waves.
