The formula Al3O2 is incorrect because the charges do not balance. Aluminum typically forms a 3+ cation and oxygen forms a 2- anion. Therefore, the correct formula should be Al2O3.
The chemical formula i2Ca is incorrect because the element symbol "i" is not recognized in the periodic table. The correct chemical formula for calcium iodide is CaI2, where calcium has a +2 charge and iodine has a -1 charge.
Li = +1; Al = +3; F = -1 but I think your formula is wrong Li3AlF6
cacl2 This refers to Calcium Chloride and is wrong. The actual formula of copper chloride is CuCl2 for cupric chloride and CuCl for cuprous chloride. The formula for urea is NH2CONH2
Proteins are not hydrocarbons. The question likely includes the wrong word (e.g. pentane, propane).
show two wrong ways to write the symbol of calcium
The correct formula for aluminum oxide is Al2O3, not Al3O2. Aluminum oxide is a compound composed of two atoms of aluminum for every three oxygen atoms.
The compound is aluminum oxide (Al2O3), not Al3O2. Aluminum oxide is commonly known as alumina and is used in various applications, including the production of ceramics, abrasives, and refractory materials.
WRONG.
To determine the number of atoms in 2Al2O3, we first need to calculate the molar mass of Al2O3. Aluminum (Al) has a molar mass of 26.98 g/mol, and oxygen (O) has a molar mass of 16.00 g/mol. Therefore, the molar mass of Al2O3 is 2(26.98) + 3(16.00) = 101.96 g/mol. Next, we convert the given quantity of 2 moles of Al2O3 into atoms using Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. Therefore, 2 moles of Al2O3 contain 2 x 6.022 x 10^23 = 1.2044 x 10^24 atoms.
There are two common formula errors. One error is that the formula is read wrong. The other error is that the formula is written down incorrectly.
Pressing f4 does not insert $ signs in a formula
Experiments carried out so far confirm the formula.
So it is wrong equation .Symbols are very important
The chemical formula i2Ca is incorrect because the element symbol "i" is not recognized in the periodic table. The correct chemical formula for calcium iodide is CaI2, where calcium has a +2 charge and iodine has a -1 charge.
Yes. It depends on the formula and what you want the formula to do. So it is easy to have the wrong formula and paste it, or have the correct formula initially, but when it is pasted elsewhere it does not use the correct values. Normally if you have your worksheet set up correctly then once the initial formula is correct, pasting it to the right place should not cause any problems.
The question is based on the false assumption that the quadratic formula is not used in daily life. Wrong, it IS!
h² is of course wrong ! The formula is H²O, without oxygen no water !
