alexandr402 [8]2 years ago
4 0

Answer:

From point, 1 mole of water = molar mass of water =18g 20 moles of water = 18 g x 20 = 360g (iv) From point, 6.022 x 1023 molecules of water = 1 mole = 18g of water 1.2044 x 1025 molecules of water Therefore, points (ii) and (iv) represent 360 g of water.

Which characteristics affect ocean water’s temperature? Check all that apply. depth location mass salinity waves
RideAnS [48]

Answer:

Depth and location affect ocean water’s temperature.

Explanation:

The main source of heat for the oceans is solar radiation. That is, water is basically heated by the radiation of the Sun, which transmits energy to the surface. The ocean absorbs this energy and stores it. Seawater has high caloric capacity. This means that more energy and more time is needed to change or increase the water temperature, compared to the air temperature. Similarly, once the ocean heats up, it takes a long time for the water to completely release or lose that heat.

The temperature decreases to greater depth, because the amount of solar radiation is reduced. On the contrary, it is greater where there is greater energy or heat content.

The closer a place is to the equator, the solar energy will affect more vertically and with more intensity on it, so the warmer the temperatures will be. The further that point of the equator is found, the solar energy will reach it with a smaller angle. And if the point is near the poles, the sun's rays will arrive at a very small angle. This causes the temperature of the water of the oceans to vary depending on the earth's latitude, being higher in areas close to the equator and the tropics, and colder the closer to the poles or the further away from the temperate zones.

How many moles of CCl4 are in 3.55L
marishachu [46]

Answer: 0.16 moles

Explanation: According to Avogadro's law, 1 mole of every gas at STP occupies a volume of 22.4 Liters.

Given: Volume occupied = 3.55 L

From Avogadro's law,

22.4 L of CCl_4 corresponds to= 1 mole

3.55 L of CCl_4 correspond to=\frac{1}{22.4}\times 3.55=0.16moles

Can you please help me?
Luda [366]
I am not entirely certain, but endothermic is a reaction in which more is kept than released, so likely not D. Sorry I couldn't be of more help, but you could probably just google endothermic reactions and get some of the information necessary. Good luck.
