Label each transition in this flow chart as a chemical change or a physical change
Elodia [21]

1) Left up: a chemical change. We can see new substance (red-blue) is formed from one blue and one red atom.

In chemical change new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.

2) Left down: a chemical change. We can see new substance (red-blue) is formed from two blue and one red atoms.

3) MIddle: a physical change. There is no new substance. Bonds are not broken.

4) Right up: a chemical change. Bonds are broken.

5) Right down: a physical change. Change of state of matter.

4 g of X2O3, an oxide of efement X, contains 2.8 g of X. How many moles of X<br> are there?
ziro4ka [17]

Moles of X are 0.925 moles.

A mole is a totally vital unit of dimension that chemists use.The mole, symbol mol, is the unit of amount of substance inside the worldwide device of gadgets. the amount quantity of the substance is a measure of how many simple entities of a given substance are in an item or sample. The mole is described as containing exactly 6.02214076×10²³ primary entities

mass  of X2O3 = 4 g

so moles = mass/molar mass

molar mass  of X2O3 =  2*X + 48 -

Given, that the mass of X = 2.8g

        mass of O = 4 - 2.8 = 1.2g

A mole of O = 1.2g/16 = 0.075 mole

∴ mole of X = 1 - 0.075 = 0.925 moles.
