Answer:
- the central atom is usually the atom with the lowest subscript in the molecular formula and the atom that can form the most bonds. If all of the atoms usually form the same number of bonds, the least electronegative atom is usually the central atom.
- molecular shape (the shape that a single molecule has) is important in determining how the molecule interacts and reacts with other molecules. Molecular shape also influences the boiling point and melting point of molecules. If all molecules were linear then life as we know it would not exist.
The masses of the nucleus and the electron cloud of an atom is balanced if false. Do you have any answer options??
<span>Answer: FALSE:
Explanation:
A reaction requires 22.4l of at STP. You have 32.0l of gas at 398k and 105.6 kpa.
1) STP stands for standard temperature and pressure.
2) Standard temperature is 0°C or 273.15 K
3) Standard pressure is 1 atm or 1013.25 kPa
4) use the ideal gas equation for both contidions
pV = n RT
=> n * R = pV /T
at STP n * R = 1031.25 kPa * 22.4 liter / 273.15 K = 84.5
at T = 398 K, p = 105.6 kPa, and V = 3.2.0 liter:
n * R = 105.6 kPa * 32.0 liter / 398 K = 8.49
Since R is a constant (the Universal Gases Constant), it is evident that the number of moles in the 32.0 liter of gas, at T = 398 K and P = 105.6 kPa is less than the number of moles of the 22.4 liter gas at STP.
There is not enough gas to carry out the reaction.

<u>Phytochemicals:</u>
<u>Defination:</u>
Phytochemicals are the compounds that are derived from plants with having activities which protect from number of factors such as anticarcinogenic, antimutagenic, antiinflammatory, and antioxidant properties
Are called hydrogen gas and oxygen gas since they are diatomic elements
