The Process Of Outgassing Help Layers of Earth To Form
Al atom has 13 protons, 13 electrons.
Mass number = number protons + number neutrons
27 = 13 + number neutrons,
number neutrons =27 - 13 = 14 neutrons .
Ion Al³⁺, lost 3 electrons.
So, in Al³⁺, 13-3=10 electrons.
So, ion Al³⁺ has 13 protons,14 neutrons, 10 electrons.
3.4 mol HCl * ( 36.46 g / 1 mol ) = 123.964 g HCl = 1.2 x 10^2 g HCl
Convert moles of HCl to grams of HCl using the molar mass ( 36.46 g/mol ).
Revise your answer to have the right number of significant figures ( 2 significant figures in this case, as determined by the the number of figures in the value with the least figures).
Answer:
Convection
Explanation:
Convection is a mode of heat transfer that involves the actual movement of particles. In this case the particles are air particles.
Since hot air is less dense, it is pushed up by the denser cool air. This process may continue indefinitely and a convection current is set up.
