The cylinder with the greater precision is the 10 ml graduated cylinder.
Precision refers to the closeness of a measurement to the true value.
A 10 ml graduated cylinder will have greater precision because it has marks for every 2 ml, this will allow you to read your measurements to two significant figures.
The 50 ml graduated cylinder on the other hand has marks for every 1 ml, this graduation will only allow the user to record measurement up to one significant figure. And you know, the more the significant figures, the more precise the measurement are.
It's B. by identifying the elements.
Reasons:
prefixes are only used for covalent compounds.
You don't include the number of atoms when you write the chemical name of a compound.
Subscripts are basically numbers that tell how many atoms of each element is in a compound. It does not identify the name of an element.
A formula must always be written using element symbols (NaCl, for example) whereas a molecule can be named using symbols (NaCl) or written (sodium chloride).
Answer:
Ocean Currents
Explanation:
The correct answer is Ocean currents.
When the earth receives solar radiation, a large fraction of this incident radiation is usually absorbed by the oceans and the seas, which become warm. Usually, equitorial regions are the ones that have this phenomenon. Now, when ocean currents are flowing from the equator, they usually carry this warm water with them thereby moving the greatest amount of heat from the equator on its way out.
For example, In the Pacific Ocean, there is a current known as Alaska Current that carries warm water in the northward direction thereby making Anchorage which is Alaska's largest city to have a much mild weather than the inland areas with the same latitude.
