Answer:
The answer to your question is: the third option
Explanation:
- those that a substance displays only through changing its composition. This option is wrong, in a physical property the matter do not change its composition.
- those that cause atoms and molecules to change. chemical properties also made that atoms and molecules change so this option is wrong.
- those that a substance displays without changing its composition. This is the correct answer, in a physical property matter do not change its composition.
- identical for all solid matter. physical properties are different for every substance, so this option is wrong.
- none of the above. it not correct, there is a correct option.
a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
The volume of ideal gas that would occupy at 1.50 atm and 216 c is
2016.49 ml
<u><em>calculation</em></u>
- volume is calculated using a combined gas equation
that is P1V1/T1= P2V2/T2
P1( pressure 1) = 7.20 atm
V1 ( volume 1) = 250 ml
T1 ( temperature 1) = 18 + 273=291 K
P2 ( pressure 2) = 1.50 atm
T2 ( temperature 2)= 216+273=489 K
V2 ( volume 2) =?
- by making V2 the subject of the formula
V2=[(T2 xP1 x V1)/(T1 xP2)]
V2=[ (489 K x 7.20 atm x 250 ml) / ( 291 k x 1.50 atm)] = 2016.49 Ml
Explanation:
Normally, fusion involves two heavy hydrogen nuclides but since we have 4 light hydrogen nuclides, two of which underwent positron emission, thus changing two protons into neutrons plus 2 positrons and 2 neutrinos. The resulting nucleus from this fusion reaction is an He-4 nucleus.
