Hello! Your answer will be C. If you need an explanation let me know!
Paper burning is a form of a physical change known as combustion. The chemical bonds in between atoms holding them together are being changed with the heat, making it different on an atomic level.
Answer:
acetyl-CoA.
Explanation:
Fatty acids are broken down into acetyl-CoA by the process of beta-oxidation inside the mitochondrial matrix part of the powerhouse of the cell. Whereas fatty acids are synthesized from acetyl-CoA in the mitochondria.
Then acetyl-CoA which is produced by beta-oxidation enters the citric acid cycle in the mitochondrion by combining with oxaloacetate to form citrate and then complete the combustion of the acetyl-CoA into carbon dioxide and water.
Answer:
[KCl] = 1.2 M
Explanation:
We need to complete the reaction:
2KCl(aq) + Pb(NO₃)₂(aq) → 2KNO₃(aq) + PbCl₂(s)↓
By stoichiomety we know that 1 mol of chloride needs 1 mol of nitrate to react:
Let's find out the moles of nitrate, we have:
Molarity = mol/volume(L)
We convert the volume → 30 mL . 1L/1000mL = 0.030L
Molarity . volume(L) = moles → 0.400 M . 0.030L = 0.012 moles
Therefore, we can make a rule of three.
1 mol of nitrate reacts with 2 moles of chloride
Then, 0.012 moles of nitrate must react with (0.012 . 2) / 1 = 0.024 moles of KCl
We convert the volume from mL to L → 20 mL . 1L /1000mL = 0.020L
Molarity = mol /volume(L) → 0.024 mol /0.020L = 1.2 M
