Answer:
5 would be the large intestine
Explanation:
A student collected the above data for this experiment.
He made an error in reporting the correct weight of graduate cylinder with water, as it has to be more than that without water.
Answer:
Formula is NA2SO4•10H2O
Sodium sulfate decahydrate.
Explanation:
Sodium sulfate is soluble in water. Soduim sulphare form various hydrates, so if the solution is open to the atmosphere for a week at least a lot of the water will have evaporated leaving behind a solid hydrate of Soduim sulfate.
Mass of anhydrous Na2SO4 = molar mass * number of moles
Molar mass = (23*2) + (32*1) + (16*4)
= 146 g/mol
Mass = 146*1
= 146 g of NA2SO4
NA2SO4•nH2O --> Na2SO4 + nH2O
Molar mass of hydrate, NA2SO4.nH2O
= (142 + 18n) g/mol
Mass of NA2SO4.nH2O = (142 + 18n)*1
= (142 + 18n) g
Mass of the residue = 322.2 g
Therefore, 142 + 18n = 322.2
18n = 180.2
n = 10
Formula is NA2SO4•10H2O
Sodium sulfate decahydrate.
0.0588 mol MgSO4 / 0.0588 = 1 mol MgSO4
0.412 mol H2O / 0.0588 = 7 mol H2O
Formula is MgSO4•7H2O
Answer:
The ocean and atmosphere are connected. They work together to move heat and fresh water across the globe. Wind-driven and ocean-current circulations move warm water toward the poles and colder water toward the equator. The ocean can store much more heat than the land surfaces on the Earth. The majority of the thermal energy at the Earth’s surface is stored in the ocean. Thus, the absorption and movement of energy on the Earth is related to the ocean-atmosphere system. the answer is B.
Answer: The net ionic equation for the cobalt-silver voltaic cell is 
Explanation: In cobalt-silver voltaic cell, one half of the cell consists of cobalt electrode immersed in
solution ( which means that
are present in the solution) and other half of the cell consists of the Ag electrode immersed in
solution ( which means that
is present in the solution)
The two electrodes are joined by the copper wire. The cobalt electrode acts as an anode and the silver electrode acts a cathode.
At anode, oxidation reaction takes place and at cathode, reduction reaction takes place.
At Anode : 
At Cathode: ![[Ag^+(aq.)+e^-\rightarrow Ag(s)]\times 3](https://tex.z-dn.net/?f=%5BAg%5E%2B%28aq.%29%2Be%5E-%5Crightarrow%20Ag%28s%29%5D%5Ctimes%203)
