Answer: The heat transfer by convection requires a solid-fluid interface, a temperature difference between the solid surface and the surrounding fluid and a motion of the fluid. The process of heat transfer by convection would occur when there is a movement of macro-particles of the fluid in space from a region of higher temperature to lower temperature.

Moles of solute for both a and b are the same = 1 mol
<h3>Further explanation</h3>
Given
a 500 cm³ of solution, of concentration 2 mol/dm³
b 2 litres of solution, of concentration 0.5 mol/dm³
Required
moles of solute
Solution
Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
Can be formulated :

a.
V = 500 cm³ = 0.5 L
M = 2 mol/L
n=moles = M x V
n = 2 mol/L x 0.5 L
n = 1 mol
b.
V = 2 L
M = 0.5 mol/L
n=moles = M x V
n = 0.5 mol/L x 2 L
n = 1 mol
Answer:
Their digestive systems produce methane, a powerful
greenhouse gas
What do you mean? Is this for anyone stuck on the same question cause I don’t think that’s how it works lol
Each substance in the mixture<span> keeps its own properties and can be </span><span>easily separated from the </span>mixture.<span> In a mixture of hydrogen and oxygen, molecules of both the gases will exist independently.</span>
The compound<span> on the other hand has properties different from the </span>elements it contains. In water as a compound of hydrogen and oxygen <span>what you will have is molecules of H20.</span>
