For liquids, which of the following factors affect vapor pressure?

Vapor pressure is essentially only affected by the particular liquid and its temperature. However this is only an approximation. So from possibilities provided I would choose. Temperature Intermolecular forces temperature and intermolecular forces! Vapor pressure describes the pressure of the vapor phase in equilibrium with the liquid phase of a substance. Intermolecular forces and temperature …

What is the derivative of sin^4(x)?

Derivative Of Sin 4 X This Site Might Help You. RE: What is the derivative of sin^4(x)? Then I need the solution f'(2) 4 sin^3(x) cos(x). You need to use the chain rule for this where f(x)= (sin(x))^4 then f'(x)=4(sin(x))^3(cos(x)) =4(sin(x))(cos(x)) then plug in x=2 For the best answers, search on this site https://shorturl.im/avqEY y …

In a redox reaction, electrons are transferred?

remember this…"reduction means reduction in charge" and this follows naturally… reduction means reduction in charge by gaining electrons oxidation means increase in charge by losing electrons. species reduced is oxidizing agent species oxidized is reducing agent. why is reduction the gain of electrons? because electrons are negative. the more negative electrons you add, the lower …
