List three evidences of physical and chemical change. ( if you know only one or two write them anyways )

Convert a speed of 201 cm/s to units of inches per minute. also, show the unit analysis by dragging components into the unit‑factor slots.

Achemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: 2 no(g) + cl2(g) < => 2 nocl(g) kp = 2 x 10^(-6)he fills a reaction vessel at this temperature with 13. atm of nitrogen monoxide gas and 12. atm of chlorine gas. use this data to answer the questions: a. can you predict the equilibrium pressure of noci, using only the tools available to you within aleks? y/nb. if you said yes, then enter the equilibrium pressure of nocl at right. round your answer to 1 significant digit.

Uuestons niuthe no. of millimoles of hcl required to neutralize 10 ml of 0.2 m na2co3 is(a) 2.0 m mole(b) 4.0 m mole(c) 0.2 m mole(d) 0.4 m mole
