Question

Experiments were done on a certain pure substance X to determine some of its properties. There's a description of each experiment in the table below.In each case, decide whether the property measured was a chemical or physical property of X, if you can. If you don't have enough information to decide, choose can't decide in the third column.QA sample of solid X is carefully weighed and put inside a sealed flask. Pure hydrogen gas is added to the flask, and the mixture heated until the hydrogen starts being consumed. After hydrogen stops being consumed, the contents of the flask are removed and weighed, and from the increase in weight the value of may be calculated.physicalchemical(can't decide)MA small sample of X is put on the pan of a sensitive balance and its weight measured. Next, a magnet is brought near the pan, and the weight is measured again. From the difference of weights in and out of the magnetic field, the value of M may be calculated.physicalchemical(can't decide)CA sample of X is carefully weighed and put inside a sealed calorimeter. Pure oxygen gas is injected into the calorimeter, and the mixture ignited. After all of X has reacted with the oxygen gas, the temperature rise of the calorimeter is measured. From this change in temperature the value of C may be calculated.physicalchemical(can't decide)

Answer 1

Step-by-step explanation:

A chemical property is one in which atoms are rearranged in the process.

-----------------

Q) In this case, this is a chemical property because hydrogen starts being consumed when the flask is heated and hydrogen combines with the solid too.

Chemical

-----------------

M) This is a physical property because nothing happens to the atoms of the different substances in the sample. The metallic particles from the sample are removed with the magnet.

Physical

----------------

C) This is chemical property because a reaction is carried out inside.

Oxygen reacts with X
