A chemical has a FW of 180 g/mole and you need 25 ml (0.025 L) of 0.15 M (M = moles/L) solution. How many grams of the chemical must be dissolved in 25 ml water to make this solution? #grams/desired volume (L) = desired molarity (mole/L) * FW (g/mole) by algrebraic re...
A nuclear power plant works pretty much like a conventional power plant, but it produces heat energy from atoms rather than by burning coal, oil, gas, or another fuel. The heat it produces is used to boil water to make steam, which drives one or more giant steam turbines connected to ...
The average mass of the atoms that make up Earth is 40 u. How many atoms are there in Earth? Mass: In physics, the term mass can be defined as the measuring of the amount of matter that any object consists of. The mass directly...
For many years, scientists couldn't figure out how atoms and molecules on the Earth combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What's ...
See our article on light for a fuller explanation of how atoms make light.Sponsored links You might think heating up a bit of wire is a pretty inefficient way to make light—and you'd be right. A fire, a hot iron bar, and the wire filament in a lamp all give off light, but they...
[04:27.93]Some of the silver gets washed away with the washing machine water. [04:35.34]Researchers wanted to know if that makes the cloth less effective. [04:43.42]So they washed the garments, many times. [04:47.71]“Even af...
Matter, as you probably know, is composed of atoms. Break something down to small enough pieces and you wind up with a nucleus orbited by one or more electrons, each with a negative charge. In many materials, the electrons are tightly bound to the atoms. Wood, glass, plastic, ceramic,...
This type of energy gets saved inside tiny atoms that remain invisible. These atoms make up the entire universe. The fission reaction that happens in nuclear plants forms enough energy to power up huge cities. 6. Solar Energy Consumption ...
So, there are more drops of water in the ocean than there are atoms in a drop of water. How many more drops depends mainly on the size of your drops, but there arebetween 1,000 and 100,000 more drops of water in the ocean than atoms in a drop of water. Source Gleick, P.H. "...
