Answer:
All chemical reactions need energy to get started. Even reactions that release energy need a boost of energy in order to begin. The energy needed to start a chemical reaction is called activation energy.
Explanation:
I found a similar question online which will help me answer your incomplete question. To make it easier, show all the elements of the compound given. It is shown in the second picture attached.
a.) The formula for unsaturation number is shown in the 3rd picture attached. Following this,
n = 8
m = 2(8) + 2 + 0 + 0 - 0 = 18
Thus,
x = Unsaturation number = (18 - 8)/2 = 5
<em>The unsaturation number is 5.</em>b.) The molar mass of C is 12.01 g/mol; H is 1 g/mol; O is 16 g/mol. So, the molecular weight is:
Molecular weight = 12.01(8) + 8(1) + 2(16) = 136.08 g/mol
<em>The molecular weight of the ester is 136.08 g/mol.</em>
Answer:
P waves is the correct answer
Answer is A) Al4C3 + 3H2O -> CH4 + 4Al(OH)3
One the left side there are 3 carbon atoms, or moles of carbon, and on the write side there is only one.
In order to solve these problems, count the number of atoms on each side and make sure that for each element, the number of atoms are equal.
For example, for the last problem, we have 1 zinc atom on each sidde, two hydrogen atoms, and two chlorine atoms.
Answer:
Well, when something is in gas state, the particles move very quickly and freely and bounce around a lot, more than in liquids and solids.
Hope this helps! If it did, please mark it as brainliest! It would help a lot! Thanks! :D
