Solid sodium reacts with water to form sodium hydroxide and hydrogen gas, according to the following equation. 2 Na(s) + 2 H2O(l) → 2 NaOH(aq) + H2(g) If the reaction is carried out with 1.15 grams of sodium and excess water at 1.21 atm and 0°C, determine the amount of pressure-volume work done (in joules) during the production of hydrogen gas.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

d. temperate deciduous forest

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.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
