Answer:
In physics, a fluid is a liquid, gas, or other material that continuously deforms (flows) under an applied shear stress, or external force.
Explanation:
They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them.
Coffee creamer is a base because if you eat it raw then it will soak up the acid in your stomach.
Answer:
C.
Explanation:
The heat island effect or the the urban heat island effect, is where the temperature of an area is higher than close rural areas. This is because materials suh and concrete and asphalt absorb the sunlight and store it, causing extreme weather.
Moles pf mgcl2= 2,11/M mgcl2=2,11/95= 0,0222
Molarity=0,0222/1,5=0,0148 M.
I hope this is correct.
Answer:
The answer to your question is letter D
Explanation:
Data
mass of Li = 4.5 g
mass of N₂ = 4.5 g
limiting reactant = ?
Reaction
6Li (s) + N₂ (g) ⇒ 2Li₃N
This reaction is balanced
Process
1.- Calculate the molecular mass of the reactants
Li = 7 x 6 = 42g
N = 14 x 2 = 28 g
Calculate the limiting reactant using proportions
Theoretical proportion Li / N = 42 / 28 = 1.5
Experimental proportion Li/N = 4.5/4.5 = 1
As the experimental proportion was lower than the theoretical, the limiting reactant is Lithium
2.- Calculate the theoretical yield of Li₃N
42 g of lithium -------------- 70 g of Li₃N
4.5 g of lithium ------------- x
x = (4.5 x 70) / 42
x = 315 / 42
<u> x = 7.5 %</u>
