Explanation:
The goodness of fit - it is proposed by Thomas and chess in 1977. This term is used to defined coordination of child temperament and environment. while poorness of fit defines when temperament is not accommodated.
The goodness of fit is generally good for children's best learning. it is basically related to individual temperament and their social environment
I believe the answer is D.
BeCl2 = Beryllium Chloride
2H2O = 2 molecules of H2O (water)
LiNO2 = Lithium Nitrate
H2O = water
Moles of ZnSO4 = Mass/Mr
= 2/(65.4 + 32.1 + (16 x 4))
= 0.012383.... mol
Since there is no chemical equation provided, I will assume that the ratio of ZnSO4:Li2CO3 is 1:1
Therefore there are 0.012383 mil of Li2SO4 as well
So the mass would be Moles x Mr = 0.012383.... x ((6.9 x 2) +32.1 + (4x16))
= 1.360 g of Li2SO4 produced
Answer:
The new volume is 2.75L
Explanation:
This is another case of Charles Gay Lussac law, where the volume varies directly proportional to T°, if the pressure keeps on constant.
V₁ / T₁ = V₂ / T₂
25°C + 273 = 298K
55°C + 273 = 328K
2.5L / 298K = V₂ / 328K
(2.5L / 298K) . 328K = V₂
2.75L = V₂
