Some potential energy was converted into thermal energy due to friction. The acceleration due to gravity became smaller as the box slid down the ramp.
Answer:
amino group
Explanation:
There are twenty (20) amino acids in nature. Generally, each amino acid is structurally made up of a central carbon atom called alpha carbon attached to a hydrogen, carboxylic acid group (-COOH) and an amine group (-NH2). However, one particular amino acid called PROLINE posseses an exception to this.
Proline, which is the only cyclic amino acid, is also the only amino acid that forms a secondary amine group i.e. loss of hydrogen atoms in its amine group when in a protein structure. This means that when in a protein, PROLINE does not have an AMINE GROUP.
It doesn't take much energy to remove one electron from a sodium atom to form an Na+ ion with a filled-shell electron configuration. The first ionization energy of magnesium is larger than sodium because magnesium has one more proton in its nucleus to hold on to the electrons in the 3s orbital.
<u>Answer:</u> The mass of carbon dioxide formed in the reaction is 269 grams.
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The chemical equation for the decomposition of calcium carbonate follows:
Let the mass of carbon dioxide be 'x' grams
We are given:
Mass of calcium carbonate = 612 grams
Mass of CaO = 343 grams
Total mass on reactant side = 612 g
Total mass on product side = [343 + x] g
So, by applying law of conservation of mass, we get:
Hence, the mass of carbon dioxide formed in the reaction is 269 grams.
