What is the formula for the ionic compound lithium and fluoride?
The formula for the ionic compound between lithium and fluoride is LiF. In this compound, lithium has a +1 charge (Li+) and fluoride has a -1 charge (F-), so they combine in a 1:1 ratio to form a neutral compound.
A fat with no carbon-carbon double bonds that is usually solid at room temperature is said to be a?
Saturated fat. Double bonds = unsaturated One double carbon-carbon bond would be monounsaturated. Many double carbon-carbon bonds would be polyunsaturated.
Choose the false statement A 1 mole equals 6.02 x 1023 amu B 6.02 x 1023 atoms equals 1 mol of atoms C 6.02 x 1023 hydrogen atoms weigh 1.008 g D 1 mol of carbon atoms weighs 12.0 g E Fluorine is a di?
First off, you should try being a little more crafty when posting a question from a quiz/homework! Second, (A) is definitely the false statement. One mole is equivalent to 6.02x1023 atoms or molecules. It's a measurement similar to "a dozen" because it only refers to the number of something, i.e. a dozen eggs and a dozen cows are two very different things except that there's 12 of them. So a mole of carbon is 6.02x1023 carbon atoms, and a mole of water is 6.02x1023 water molecules, even though a carbon atom and a water molecule weigh different amounts, are different in size, etc. (A)"1 mole equals 6.02 x 1023 amu" - This would be like saying a dozen eggs equals twelve lbs. Like I said above, a mole is just a quantity of something, just a count, while an atomic mass unit (amu) is a measurment of mass (specifically the mass of one-twelve of a carbon atom, or more simply and less accurately the mass of a proton). This is the false statement. (B) "6.02 x 1023 atoms equals 1 mol of atoms" - This is like saying "Twelve eggs is a dozen eggs". It's true. (C) "6.02 x 1023 hydrogen atoms weigh 1.008 g" - Here's a cool thing about moles: One mole (specifically a "gram mole" if you're an engineer) of something has the mass of its elements in grams. Basically, one hydrogen atom weighs 1.008 amu, so if you use the same numner ("1.008") but instead of "amu" use "grams", that's the mass of a mole of hydrogen. It's a conversion you'll use non-stop in chemistry classes. So this statement is true. (D) "1 mol of carbon atoms weighs 12.0 g" - Same as (c), one mole of something weights the atomic mass of that same something, but in grams. (E) "Fluorine is a di" - I'm going to guess this was "Fluorine is a diatomic molecule" but was cut-off by the website. The answer to this is, yes, fluorine exists in its elemental form as a diatomic molecule (i.e. when you mention "fluorine" or "fluorine gas" it usually means F2). A good way to remember the diatomic molecules is: BrINClHOF (pronounced "brinkle-hoff"). Bromine (Br), Iodine (I), Nitrogen (N), Chlorine (Cl), Oxygen (O), and Fluorine (F) all exist as diatomic molecules "in the wild" so to speak. Now get back to your quiz/homework!
What is 6.022 x 1023?
6.022 x 10^23 is the Avogadro's number, which represents the number of atoms, molecules, or particles in one mole of a substance. It is a key constant in chemistry and is approximately equal to 6.022 x 10^23.
What is the osmolarity of a solution that has 1 mole of glucose 1 mole of sodium and 1 mole of chloride?
Osmolarity is defined as the # of particles in solution.A rule to keep in mind is likes dissolve likes. So a covalently bonded substance like oil will only dissolve in a covalent solution. Same for polar substances etc.That said, glucose being covalent, will NOT dissolve in water, while the ionic compound NaCl will.The result is:Glucose --> GlucoseNaCl --> Na+ and Cl- (Both are ions)By the definition of osmolarity, glucose only produces 1 mol of particles, while NaCl produces 2. Those two numbers are their respective osmolarities.
How many pounds in one mole?
Mole is a unit of quantity, just like a dozen is a unit of quantity. So you cant say a mole equals this many pounds because it will matter of what it is you are measuring. A dozen apples weighs less than a dozen elephants, the same can be said for moles.
If a quantity increases as a second quantity increases and decreases as the second quantity decreases the two quantities are said to be?

Does the lithium have 3 protons 3 electrons and 4 neutrons?
It has 0 neutrons. The number relates to the number of nucleons in the isotope. Lithium must have 3 protons to be lithium, and 3-3 leaves 0 neutrons. ie. Carbon has 6 protons, so the isotopes Carbon-11 and Carbon-12 have 11-6 = 5 neutrons and 12-6=6 neutrons respectively. Lithium-3 is so unstable that it cannot be created, said another way, there is no bound state between 3 protons. The lightest lithium isotope is Lithium-4, which has a lifetime of about 9.1 X 10^-23 seconds, or 91 millionths of a millionth of a millionth of a second. Lithium-4 decays to Helium-3 by proton emission.
Who said mole is the unit for measuring matter?
you do not no any thing
How many moles is 3 grams of carbon?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Carbon's atomic mass is 12.011 grams.
A 1.0-mole sample of krypton gas has a mass of?
Since one mole is 6.02e23 of any atom, the atomic weight is equal to one mole of any element. For example, one mole of Ca is 40.08, one mole of S is 32.07. Thus being said, one mole of krypton is 83.80!
What does it mean if you have a mole on your penis?
it means that you have a mole on your penis lol but asain cultures have said that it means your gonna be very horny all the time who knows?
What are compounds that contain carbon said to be?
They are said to be "organic" compounds.
What weighs more a mole of sucrose or a mole of water?
A mole of water weighs more than a mole of sucrose. This is because the molar mass of water (18 g/mol) is less than the molar mass of sucrose (342 g/mol).
What is the chemical formula for lithium chlorate?
first of all lithium and iron are TWO TOTALLY DIFFERENT ELEMENTS!!!!! i tried to get what is the chemical formula for lithium chlorate and it said it is the same as iron chlorate! last time i check lithium and iron are on two opposited parts of the periodic table. anyways the answer is most likely Li(ClO3)3
Who said one mole of gas contains avogadro's number of atoms?
Amadeo Avogadro!
What is the relationship between two quantities in which one quantity depends on the other?
In that case, one quantity (the quantity that depends on the other) is said to be a function of the other quantity.
