Answer:
<u>Convection</u>
Explanation:
<u>Convection definition</u>:
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
An isotope of Aluminium, a 'normal' Al atom would have a proton number of 13 (as this does not change in isotopes of the same element) but only 14 neutrons. This isotope of Al has 1 extra neutron than regular Al.
Answer:
chromium:oxygen=1:2
Explanation:
total mass=2.16g
mass of chromium=1.34g
mass of oxygen=2.16g-1.34g=0.82g
chromium oxygen
mass:1.34g 0.82
RAM:52 16
divide the mass with the RAM
0.02577 0.05125
divide by smallest number to find ratio
1 2
ratio of chromium to oxygen=1:2
Answer:
mass = 2.65 [nearest hundredth].
Explanation:
Mass = Density / Volume
mass = 1000 / 376.8
mass = 2.653927813163.. ≈ 2.65
The partial pressure of the oxygen gas in the mixture is calculated is calculated as follows
total pressure of oxygen + nitrogen
the partial pressure of oxygen percentage of 0xygen / total percentage x total pressure
= 10/100x800= 80 mmHg
