Answer:
D.+1°e symbol represents a type of radiation that has the same mass as an electron and a positive charge.
Answer:
There are 0,2 moles of gas that ocuppy the container.
Explanation:
We apply the formula of the ideal gases, we clear n (number of moles); we use the ideal gas constant R = 0.082 l atm / K mol. Firs we convert the unit of temperature in Celsius into Kelvin:
0°C= 273 K ------> 45,6 °C= 273 + 45, 6= 318, 6 K
PV= nRT ---> n= PV/RT
n= 1,48 atm x 3,45 L /0.082 l atm / K mol x 318,6 K
n= 0,195443479 mol
In a group,the ionization energy decreases because the atomic size increases(no. of shells increases, therefore due to this, there's a weak attractive force between nucleus and the valence electrons)
True, as an atom has the same chemical properties as the first bulk element. Dalton’s Atomic Theory explains all :))
