A sample of a compound of iron is analysed. the sample contains 0.547g of potassium, 0.195g of iron, 0.252g of carbon and 0.294g nitrogen

If 3.00 g of titanium metal is reacted with 6.00 g of chlorine gas, cl2, to form 7.7 g of titanium (iv) chloride in a combination reaction, what is the percent yield of the product?

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

Avariable that is not being directly tested during an experiment should be changed varied experimented controlled
