Answer:
Carbon dioxide is composed of one carbon atom covalently bonded to two oxygen atoms. It is a gas (at standard temperature and pressure) that is exhaled by animals and utilized by plants during photosynthesis. Carbon dioxide, CO2, is a chemical compound composed of two oxygen atoms and one carbon atom
Explanation:
Answer:
Energy levels 4-7
Explanation:
The energy levels in an atom are shown by the principal quantum number (n). Typically, the d orbitals begins to occur from the third energy level through the seventh energy level.
Most second and third row d-block elements are found between energy level n=4 and energy level n= 7 in the periodic table. Hence the answer
For example phosphorus and oxygen can covalently bond to form a polyatomic ions, PO4³⁻ and PO3³⁻.
Data:
Q = 402.7 J → releases → Q = - 402.7 J
m = 16.25 g
T initial = 54 ºC
adopting: c = 4.184J/g/°C
ΔT (T final - T initial) = ?
Solving:
Q = m*c*ΔT
-402.7 = 16.25*4.184*ΔT
-402.7 = 67.99*ΔT
If: ΔT (T final - T initial) = ?
Answer:
I THINK 25,000 CG CONVERTS TO 250G
