Answer:
It increases by a factor of eight
Explanation:
When temperature is held constant, gas pressure changes according the volume, in undirectly proportion.
Volume increases → Pressure decreases
Volume decreases → Pressure increases
As volume gas, was reducted from 4L to 0.5L, it was reduced by 1/8, so the pressure gas was increased by a factor of eight.
Explanation:
divide the weight in grams by the atomic mass from the periodic table, then multiply the result by Avogadro's number..
Hope this works!!
Answer:
See below in bold.
Explanation:
Nitrogen, Hydrogen and Oxygen are the elements present in ammonium nitrate.
The Molar Mass = 2N + 4H + 3 O
= 2*14.007 + 4*1.008 + 3*15.999
= 80.043.
Percentage of Nitrogen = (2 * 14.007) * 100 / 80.043
= 35.00 %.
Percentage of Hydrogen = (4* 1.008) * 100 / 80.043
= 5.04%.
Percentage of Oxygen = (3 * 15.999) * 100 / 80.043
= 59.96 %.
Answer:urenium
Explanation: because his atomic number is 235
Answer:
Newton's First Law of Motion: Any object remains in the state of rest or in uniform motion along a straight line, until it is compelled to change the state by applying external force.
Newton's Second Law of Motion: The rate of change of momentum is directly proportional to the force applied in the direction of force.
Newton's Third Law of Motion: There is an equal and opposite reaction for evrey action
