Answer:
156 mL will be the new volume of the shape
Explanation:
First of all, we need to convert the Torr to atm.
1220 Torr . 1 atm / 760 Torr = 1.60 atm
When the temperature remains constant, it is satisfied that the volume is modified indirectly proportionally.
Pressure is increased, then volume decreases
Pressure is decreased, then volume increases
P₁ . V₁ = P₂ . V₂
0.768 atm . 325mL = 1.60 atm . V₂
V₂ = 0.768 atm . 325mL / 1.60 atm → 156 mL
Electronic structure refers to the way atoms are organized according to electron shell theory. It tells us what energy level the electrons are in and the number of electrons per energy level.
The groups of the periodic table are classified according to the valence electrons, that is, the electrons that they have in their last energy level. These electrons can make an atom more or less reactive. For example, an element in the last period, period 8. It has 8 valence electrons, that is, it complies with the octet rule and these atoms are very stable. Therefore, its reactivity is very low compared to other groups.
Groups 1 and 7 are quite reactive since group 1 has an electron in the last energy level. So it only has to lose one electron to form a bond and react. Group 7 has 7 electrons in its last energy level, that is, it needs 1 electron to form a bond. In general, group 7 elements are very reactive with group 1 elements.
So the main difference in group reactivity will be the valence electrons.
Answer:
Dyes fade by being exposed to direct sunlight over a period of two weeks.
Explanation:
Answer:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
