What volume will 600ml of gas at 2 degrees celcius and a pressure of 520 mmhg occupy if the temp is reduced to -45 degrees celsius and pressure is increased to 690 mmhg

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.

                             

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab. 

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o
