How many moles are there in 3.4 g of NaCl? What is the mass of 0.76? How many formula units are there in 3.45 g of magnesium chloride? If you have a bottle containing 8.10 grams of magnesium, how many Mg atoms are present in the bottle?
How many atoms are in sodium bicarbonate?Chemical Compounds:A chemical compound is created when atoms of more than one element bond together. An example of a chemical compound is NaCl, which is sodium chloride, known commonly as table salt. One molecule of NaCl has one atom of sodium (Na)...
In nature, magnesium can be found in many different forms, bonded with other atoms, such as: Magnesium chloride, found naturally in the sea Magnesite, the insoluble rock salt also known as magnesium carbonate In plant matter, as the central element in chlorophyll ...
How many iron (III) ions are there in 5.00 g of Fe2O3? How many valence electrons are in an atom of chlorine? How many valence electrons are in an atom of chlorine (Cl)? How many electrons are in the 3rd orbital of copper(I) ions? What is the oxidation number of fluorine in Xe...
In an example of a simple chemical reaction, one atom of potassium (K) can react with one atom of chlorine (Cl) to form a molecule of potassium chloride (KCl) with nothing left over. But this is not because potassium atoms and chlorine atoms have the same mass. Instead, it is because...

They're steeped in yellowish sweat stains, sunscreen, road grime and blood ... and they smell like it, no matter how many times I wash them. Instead of fighting those intractable stains, I wear them with pride. After all, they are a visible reminder of the hard workouts I've slaved ...
You can convert grams to ounces and/or pounds just by using some simple multiplication and division. You'll use the conversion that tell you there are 0.0352739619 oz. in a gram and 16 oz. in a pound. If you want to do calculations that tell you how to c
The chemical bonds between the atoms are shared pairs of electrons. Chemical bonds are much like springs: They can bend and stretch. These properties are important in detecting ethanol in a sample by infrared (IR) spectroscopy. Read More Types of Devices: Intoxilyzer Diagram of the Intoxi...
Crude oils are such a useful starting point for so many different substances because they contain hydrocarbons. Hydrocarbons are molecules that contain hydrogen and carbon and come in various lengths and structures, from straight chains to branching chains to rings. There are two things that make hy...
