Answer:
It's spontaneous in the reverse direction
Explanation:
A negative voltage indicate s that the reverse reaction is spontaneous (i.e. oxidation at the cathode, and reduction at the anode; by convention you would need to swap the labels on the electrodes)
The five types of states of matter are solid, liquid, gas, plasma and Bose-Einstein condensate.
Solid objects do not move a lot relative to themselves. Their molecules stay stacked neatly with no intermolecular spaces. They do not have much energy, or heat hence the molecules in solid state don't show movement.
Liquid state have more heat and more energy and a little more intermolecular space than solid. Their molecules are no longer stacked neatly due to presence of air capsules, but they still touch each other. Their structure is uncertain and can flow, their shape will alter quickly and dramatically with outside forces, but they will essentially remain a single mass unless pushed apart.
Gasses have even more energy than liquid and solid. Due to presence of high intermolecular spaces they flow like liquids, but are even more susceptible to the forces acting on them. Their molecules don’t touch each other, but are still close enough to bounce into one another frequently.
Plasma is the state of matter which is like a gas on steroids. Molecules of plasma might start in the same area, but rarely touch each other. Plasma molecules have lost electrons, and have become charged. Plasma molecules set other things on fire, and even vaporize them.
Bose-Einstein condensate or BEC was first created by scientists in the year 1995. This was created using a combination of lasers and magnets, Eric Cornell and Carl Weiman, scientists at the Joint Institute for Lab Astrophysics (JILA) in Boulder, Colorado, cooled a sample of rubidium to within a few degrees of absolute zero.

Answer:
The vertical columns of the periodic table are called groups, or families. The significance is elements with similar properties are placed in the same vertical columns. The horizontal rows of the periodic table are called periods. The significance is that properties vary from left to right along the rows.

Answer:
productivity and water depth
Explanation:
The productivity and the depth of water are both equally important as it directly affects the accumulation of biogenic sediments such as the siliceous ooze and calcareous ooze. In the equator and the coastal upwelling areas, and at the site of divergence of oceans, there occurs a high rate and amount of productivity, and these are considered to be the primary productivity.
The siliceous oozes are a good indicator of extensively high productivity in comparison to the carbonate oozes. The main reason behind this is that the silica can be easily dissolved in the surface water. On the other hand, the carbonates dissolve at a relatively lower ocean water depth, so there requires a high amount of surface productivity in order to allow these siliceous oozes to reach the ocean bottom.
Thus, the water depth and productivity, both are considered as the limiting factor in determining the accumulation of biogenic oozes.
