Answer:
113
Explanation:
We are given that the atom of cadmium has 66 neutrons:
Number of neutrons in Cd = 66
Now;
Mass number = ?
The mass number of an element is the sum of the number of protons and number of neutrons
Mass number = number of protons + number of neutrons
By the position of cadmium, it has an atomic number of 47 and this is the number of protons
Mass number = 47 + 66 = 113
Answer:
Precipitate
Explanation:
A precipitate is a solid formed from a chemical solution
We are given with a <span>temperature of 273.15 Kelvin and a pressure of 101.325 kPa. Using PV=nRT rule of ideal gas, where P is pressure, V is volume, n is the number of moles, R is the gas constant and T is temperature, we can conclude that the conditions are under STP(standard temp and pressure) and one mole of this gas occupies 22.4 L of volume.</span>
A climograph is a dual-purpose graph, showing two different kinds of information. A bar graph shows how much precipitation a given place receives during a period of time. A line graph shows the temperature conditions for the same place during the same period of time.
Well I assume it’s 20/4 which is 5
