If you mean -(x^2) * x then the answer is -x^3 if you mean (-x)^2 * x then the answer is x^3

This question is ambigous. If you mean (x+6)/x then it simplifies to 1 + (6/x) If you mean x + (6/x) then it can't really be simplified.

Mean absolute deviation = sum[|x-mean(x)|]/n Where mean(x) = sum(x)/n and n is the number of observations. |y| denotes the absolute value of y.

The "x" means unknown.

No. If you mean 4Al3O2. And If you mean 4Al + 3O2 ------> AL2O, it is still not balance.

Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1) This tells us there is 0.125 mol of oxygen gas present. The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23) So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules

20 x 2 x 6.022x1023 = 2.409x1025 atoms of oxygen

There are 0.325 moles of O2 in 5.2g, which contains 2 oxygen atoms per molecule of O2. Therefore, there are 0.65 moles of oxygen atoms. Since one mole of O2 contains 2 moles of oxygen atoms, there are 1.3 moles of oxygen atoms in 5.2g of O2.

There are 1/6.022 x 1023 = 1.66 x 10-24 moles of oxygen in 1 molecule of O2.

The molar mass of oxygen is 16.0 g/mol. Therefore, in 4.0g of oxygen, there are 4.0/16.0 = 0.25 moles of oxygen. Since each mole of oxygen contains 6.022 x 10^23 atoms, there are 0.25 x 6.022 x 10^23 = 1.5055 x 10^23 oxygen atoms present in 4.0g of oxygen.

There are approximately 0.625 moles of oxygen gas in 40.0 grams. Since the formula for oxygen gas is O2, there are 0.625 moles x 2 = 1.25 moles of oxygen atoms. Therefore, there are approximately 1.25 x 6.022 x 10^23 = 7.53 x 10^23 oxygen atoms in 40.0 grams of oxygen gas.

1.2 moles of oxygen atoms represent approximately 7.2 x 10^23 oxygen atoms. This is because 1 mole of any element contains Avogadro's number (6.022 x 10^23) of atoms. So, 1.2 moles would contain 1.2 times Avogadro's number of oxygen atoms.

If you mean -(x^2) * x then the answer is -x^3 if you mean (-x)^2 * x then the answer is x^3
