Alright yo, I just gave this explanation off earlier
Alright dude, Hess' law isn't as complicated as most people think
Take this example
look for the change in enthalpy of A+B-> AB
A + B -> C enthalpy=10 kJ
C -> AB enthalpy=10 kJ
now if you add everything together you come up with
A + B + C --> AB + C enthalpy= 10kJ + 10 kJ= 20kJ
But notice how C is one the left and on the right of that-- so if it's on the left and on the right of the equation, you could just cancel it out
so you get A+B--> AB
tadaaa!! You found the equation you were looking for
and you know that it's enthalpy is= 10kJ + 10kJ= 20kJ
Hope that helps ya fam!
Just pm me if you need more help!
Answer:
True
Explanation:
Carbon atom combine with other elements and form covalent compounds.
For example:
Carbon covalent compound with hydrogen.
Carbon combine with four hydrogen atoms through four single covalent bond. The compound formed is called methane.
Formula:
CH₄
Carbon with oxygen:
Carbon combine with oxygen and form carbon mono oxide and carbon dioxide.
In carbondioxide carbon form two double covalent bonds with two atoms of oxygen.
In carbon monoxide carbon form triple bond with oxygen.
Drainage basin. the land area from which a stream gets its water, also called a watershed.
Hope this helped ^^
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.
In general, heat insulators. Examples of these would be plastic/ rubber
