1 Students perform several experiments recording the reactions in lab journals. The students write and balance the chemical equations for each reaction and include the state of matter notations for each compound. The equations are below. Equations from Experiments Experiment 1 MgO(s) + H2O(1) ► Mg(OH)2(aq) Experiment 2 4Fe(s) + 302(9) - 2Fe2O3(s) Experiment 3 SO3(g) + H2O(1) - H2SO4(aq) Which chemical involved in the student experiments is dissolved in water?

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

i'm pretty sure it is letter c.) car

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

no statements shown

the atomic number of carbon is six, which means that a carbon atom has six protons. carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. which of these statements are true about carbon and its isotopes? select all that appl
