Which of the following relationships is/are CORRECT for gases? 1. The moles of a gas is inversely proportional to its volume (at constant pressure). 2. The volume of a gas is inversely proportional to its temperature in kelvin (at constant pressure). 3. The pressure of a gas is directly proportional to its temperature in kelvin (at constant volume).

answer: a chemical reaction

explanation:

im not wrong

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
