Answer : The value of of the reaction is, -369.2 KJ
Explanation :
Formula used :
where,
= internal energy of the reaction = ?
= enthalpy of the reaction = -184.6 KJ/mole = -184600 J/mole
The balanced chemical reaction is,
when the moles of are 2 moles then the reaction will be,
From the given balanced chemical reaction we conclude that,
= change in the moles of the reaction = Moles of product - Moles of reactant = 4 - 4 = 0 mole
R = gas constant = 8.314 J/mole.K
T = temperature =
Now put all the given values in the above formula, we get:
Therefore, the value of of the reaction is, -369.2 KJ
The difference is in how the vitamins are dissolved into the body. Vitamin C is water soluble, so your kidneys are able to filter them out and expel them from the body. Whereas vitamin A is fat soluble and the body cannot get rid of those vitamins and just store them inside the body.
Answer: Simple squamous epithelium is the type of epithelial tissue that lines the air sacs and allows the exchange of substances like gases.
Explanation:
Simple cuboidal epithelium is made up of a single layer of these cube shaped cells that are mostly involved in absorption of substances.
Strontium (Sr) lies in the second group of the periodic table, which means it has two valence shell electrons so it forms the Sr⁺² ion. Meanwhile, bromine (Br) has seven valence shell electrons, which means it forms the Br⁻ ion. Each strontium atom is therefore able to donate electrons to two bromine atoms. So the ratio of the ions in neutral strontium bromate (SrBr₂) will be 1 : 2.
