According H2X+OH → X2 + H20 (unbalanced equation); The ion formed as a product, X2-, have 36 total electrons.
a) What is element X?
b) Propose a name for H_X.
c) 35.6 mL of 0.175 M OH solution was required to completely
neutralize a sample of H2X, . What was the mass of the H X sample
used?

Alarge marble is dropped in a graduated cylinder with 35ml of water in it.the water level increases to 49ml.what is the volume of the marble

Acrystal that absorvd water from air is (blank)a. aqueousb. homogenousc. hygroscopicd. efflorescent

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
