D) Encuentra el voltaje uno, dos y tres (V1, V2 y V3) del circuito en serie que está en el ejemplo, para cada una de las resistencias aplicando la ley de Ohm( V= I R), Sabiendo que I = O,2 A. =l1 = l2 = l3,

What is the pressure of 0.500 moles of carbon dioxide gas in a 2.5 l tank and at a temperature of 301 k? (r=0.0821 l·atm/mol·k) 3.08 atm 1.2 atm 0.23 atm 4.01 atm 4.94 atm

Which one of the following is an oxidation-reduction reaction? naoh + hno3 --> h2o + kno3 naoh + hno3 --> h2o + kno3 so3 + h2o --> h2so4 cacl2 + na2co3 --> caco3 + 2 nacl ch4 + 2 o2 --> co2 + 2 h2o al2(so4)3 + 6 koh --> 2 al(oh)3 + 3 k2so4

Water is called the universal solvent because more substances dissolve in water than in any other chemical. this has to do with the polarity of each water molecule. the hydrogen side of each water (h2o) molecule carries a slight positive electric charge, while the oxygen side carries a slight negative electric charge.
