Answer:
Zero-Nine
Explanation:
this is becasue these numbers are rather small and if you plug these numbers into an equation you will most likely get 0.
Cellular respiration involves breakdown of glucose into carbon dioxide and water in presence of oxygen, releasing energy. ... ATP molecule is converted into ADP molecule, whenever energy is needed for any metabolic reaction or activity. The energy stored in it is released to be used in metabolic reaction.
Hope this helps! So sorry if I'm wrong
Answer:
There were originally 8 atoms of Potassium-40.
Explanation:
The half-life of a radioactive material is the time taken for half the original material to decay or the time required for a quantity of the radioactive substance to reduce to half of its initial value.
If the original material formed without any Argon-40, it means that the atoms originally present were Potassium-40 atoms.
Presently, there are 7 Argon-40 atoms for every 1 of Potassium-40, we can deduce the number of half-lifes the Potassium-40 has undergone as follows :
After one half-life, (1/2) there will be one Potassium-40 atom for every Argon-40 atom.
After a second half life, 1/2 × 1/2 = 1/4: there will be one Potassium-40 atom for every three atoms of Argon-40.
After a third half-life, 1/4 × 1/2 = 1/8: there will be one Potassium-40 atom for every 7 atoms of Argon-40.
Since there are 1/8 atoms of Potassium-40 presently, there were originally 8 atoms of Potassium-40.
Answer:
The only balanced equation is:
2KClO₃ → 2KCl + 3O₂
Explanation:
In reactant side: 6 atoms of O, 2 atoms of Cl and 2 atoms of K
In product side: 2 atoms of K and 2 atoms of Cl + 6 atoms of O
CO + 3H₂ → CH₃OH
In reactant side: 1 C, 1 O and 6 H
In product side: 1 C, 4 H and 1 O
PCl₃ + 2Cl₂ → PCl₅
In reactant side: 1 P, 7 Cl
In product side. 1 P, 5 Cl
Mg + N₂ → Mg₃N₂
In reactant side 1 Mg and 2 N
In product side 3 Mg and 2 N
Answer:
Rubidium is a typical but very reactive member of the series of alkali metals. It is appreciably more reactive than potassium, but less so than caesium, and so would be expected to react more violently with those materials that are hazardous with potassium or sodium.
