Calculate the δg for the following system. then state if the system is spontaneous or not spontaneous. δh = 147 kj δs = -67.0 j/k t = 149 °c 3.5 x 104 kj; not spontaneous -8.3 kj; not spontaneous -41 kj; not spontaneous 3.5 x 104 kj; spontaneous -8.3 kj; spontaneous -41 kj; spontaneous

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

50.23 i believe is correct but don't quote me on that.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
