The number of H atoms in 3(NH₄)₂CrO₄ = 24
Further explanationThe empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
Subscripts in the chemical formula indicate the number of atoms
The compound of 3(NH₄)₂CrO₄ ( 3 molecules of (NH₄)₂CrO₄ ) :
Number of H :
[tex]\tt 4\times 2(subscript)\times 3(coefficient,number~of~molecules)=24~atoms[/tex]
The number of Hydrogen (H) atoms in the compound, 3(NH₄)₂CrO₄ is 1.44×10²⁵ atoms
How to determine the mole of HMole of 3(NH₄)₂CrO₄ = 1 mole Mole of H in 3(NH₄)₂CrO₄ = 3 × 8 = 24 moles How to determine the number of atomsFrom Avogadro's hypothesis,
1 mole of H = 6.02×10²³ atoms
Therefore,
24 moles of H = 24 × 6.02×10²³
24 moles of H = 1.44×10²⁵ atoms
Thus, the number of atoms of H in 3(NH₄)₂CrO₄ is 1.44×10²⁵ atoms

Do positively charged ions gain or lose electrons
Answer:
Atoms often get electrons or lose. The atom lacks or earns a "negative" load. Then these electrons are known as ions. Positive ion - If the molecule lacks an electron, it gets more protons than ions.

Explanation:
Se sabe que un compuesto contiene 33.002% de carbono,9.063% de hidrogeno y el resto de oxigeno. El espectrometro de masas indica que la masa molecular aproximada es de 191g/mol(cual es la formula empirica y molecular probable
Answer:
CH3O
C6H18O6
Explanation:
Porcentaje de masa de oxígeno = 100% - (33,002% + 9,063%) = 57,935%
Divida el porcentaje en masa de cada elemento por su masa atómica relativa;
H- 9.063 / 1, C- 33.002 / 12, O - 57.935 / 16
H- 9.063, C- 2.75, O- 3.62
Dividir por la proporción más baja;
H-9.063 / 2.75, C- 2.75 / 2.75, O- 3.62 / 2.75
H- 3, C-1, O- 1
Fórmula emperical = CH3O
Dado que la masa molecular es 191 g / mol
Sea n el número de cada átomo de la molécula
Por tanto, su fórmula molecular es; (CH3O) n = 191
[12 + 3 (1) + 16] n = 191
31n = 191
n = 191/31
n = 6
Por lo tanto, la fórmula molecular del compuesto es; (CH3O) 6 que es C6H18O6
What has the lowest ionization erergy?
Fluorine (F)
O Francium (Fr)
O Helium (He)
O lodine (1)
Answer:
Francium (Fr)
Explanation:
From the given choices, francium will have the lowest ionization energy.
Ionization energy is the energy required to remove the most loosely held electron within an atom.
The magnitude of the ionization energy depends on the characteristics of the atom in relation to its nuclear charge, atomic radius, stability etc.
Generally on the periodic table, ionization energy increases from left to right on the tableAs you go from metals to non-metals and to gases, the value of the ionization energy increases steadily. Down the group, the value reduces. Since Francium is the most metallic of all the given choices, it has the highest ionization energy.NEED HELP ASAP!
What makes Carbon-14 so useful in “carbon dating” or “radiodating”?
Answer:
Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon. ... The carbon-14 method was developed by the American physicist Willard F. Libby about 1946.

photosynthesis affect the
productivity of cellular
respiration?
Answer: it’s the chemicals between the biological
Explanation:
The productivity of photosynthesis affect the productivity of cellular respiration by providing energy.
What is photosynthesis?Photosynthesis is a process where plants prepare their food in the presence of sunlight.
Photosynthesis process chemically illustrated as :
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
From the above it is clear that carbohydrate is produced in the photosynthesis process and this carbohydrate provide energy to the plant for the completion of another chemical process. So, for the cellular respiration plants use this energy.
Hence, the productivity of photosynthesis directly affect the productivity of cellular respiration.
