Well, Cellular Respiration does a lot for your body in many ways! It breaks down the sugars, fats, and proteins and gives your body the energy (ATP) it needs from that.
Answer:
True
Explanation:
Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely, like blocks in a box. Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed.
Answer:
Explanation:
Compound
A compound contains atoms of different elements chemically combined together in a fixed ratio.
Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule. Elements that compose the compound are chemically combined.
A compound can be separated into simpler substances by chemical methods/reactions.
A huge, virtually limitless, number of chemical compounds can be created. Compounds are classified into molecular compounds, ionic compounds, intermetallic compounds and complexes.
A compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound
Element
An element is a pure chemical substance made of same type of atom.
Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus.
Elements cannot be broken down into simpler substances by chemical reactions.
There are about 117 elements that have been observed. Can be classified as metal, non-metal or metalloid.
An element is represented using symbols.
Answer:
NO2- + 5H2O + 2Al + OH- → NH3 + 2Al(OH)4-
There is 1 hydroxide ion, on the reactant side
Explanation:
NO2−(aq) + Al(s) → NH3(aq) + Al(OH)4−(aq)
Step 1: The half reactions
NO2- (aq) → NH3(g)
Al(s) → Al(OH)4-
<u>Step 2: </u>Balancing electrons
NO2- → NH3
On the left side N has an oxidation number of +3 and on the right side -3.
NO2- +6e-→ NH3
Al(s) → Al(OH)4-
On the left side, Al has an oxidation number of 0 and on the right side +3.
Al(s) → Al(OH)4- +3e-
To have the same amount of electrons transfered, we have to multiply the second reaction by 2
NO2- +6e-→ NH3
2(Al(s) → Al(OH)4- +6e-)
<u>Step 3:</u> Balance with OH/H2O
NO2- +6e +5H2O → NH3 +7OH-
2Al +8OH- → 2Al(OH)4- + 6e-
<u>Step 4:</u> The netto reaction
NO2- + 5H2O + 2Al + 8OH- → NH3 +7OH- + 2Al(OH)4-
NO2- + 5H2O + 2Al + OH- → NH3 + 2Al(OH)4-
There is 1 hydroxide ion, on the reactant side
The molar mass is 65.38 u
