Answer:
ions; when atom lose or gain electron
Explanation:
when an atom lose electron it becomes positive ion (cation) when an atom gain electron it becomes negative ion(anion)
isotope has same number of atomic number (proton) but different neutron number which affects mass number
Answer:
7200 kPa
Explanation:
Applying,
PV/T = P'V'/T'................ Equation 1
Where P = Initial pressure of neon gas, V = Initial volume of neon gas, T = Initial temperature of neon gas, P' = Final pressure of neon gas, V' = Final volume of neon gas, T' = Final Temperature of neon gas
Make P' the subject of the equation
P' = PVT'/V'T.............. Equation 2
Given: P = 900 kPa, V = 8.0 L, T = 300 K, V' = 2.0 L, T' = 600 K
Substitute these values into equation 2
P' = (900×8×600)/(2×300)
P' = 7200 kPa

There are two general classifications of mixtures: homogeneous mixture and heterogeneous mixture. Since sugar dissolves in water, this is a homogeneous mixture. In other words, it is called as a solution. Furthermore, there are 3 classifications of solution: unsaturated, saturated and supersaturated. Since only a few are added to the water and all of them dissolved, this is an unsaturated homogeneous mixture.
