Explanation :

Physical property : It is defined as a change in which the identity of substance does not change.

Physical change : It is defined as something observed while keeping the identity of the substance the same.

Homogeneous mixture : It is defined as something made up of at least two different substances and is usually very difficult to separate. Even distribution of particles.

Heterogeneous mixture : It is defined as something made up of at least two different substances and easily separated by physical means. Unequal distribution of particles.

Chemical property : It is defined as something observed by changing the identity of a substance.

Compound : It is defined as a pure substance made up of at leat two different elements.

Matter : It is defined as anything that has matter and takes up space.

Chemical change : it s defined as a change that creates a new substance or compound.

Extensive property : It is defined as a property that change with the amount of matter present.

Mass : It is defined as the amount of matter contained in an object.

Volume : It is defined as the amount of space a substance takes up.

Intensive property : It is defined as a property that does not change with the amount of matter present.

given the reactants, h2so4 and koh, we are asked to determine the product(s) of the reaction. since h2so4 is an acid and koh is a base. this is a neutralization reaction, thus, the products are salt and water. 

so, h+ from h2so4 will react with oh- from koh forming h2o. k+ will also react with so4 2- forming k2so4. therefore, the balanced reaction will be:

h2so4 + 2koh > k2so4 + 2h2o
