Arrange the following compounds in order of decreasing basicity: MgO, Cs2O, Cl2O7, SnO2, P4O10
2 answers:
Answer:
5) Cs2O > MgO > SnO2 > P4O10 > Cl2O7
Explanation:
Hello,
In this case, the decreasing basicity order depends on the metal contained into the oxide, in such a way, on the attached picture you will find how the basicity increases leftwards and downwards on the periodic table, as the metallic character does.
In this manner, as the cesium in the Cs₂O is the leftest atom, it is the most basic, next MgO, afterwards SnO₂, then P₄O₁₀ and finally Cl₂O₇, therefore, the order is: 5) Cs₂O> MgO > SnO₂> P₄O₁₀> Cl₂O₇.
Best regards.

<h3>What is specific heat capacity?</h3>The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases by 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).
Given,
the mass of Na is 23 g
The volume of water = 293 cm3
Mass of water = 293 g
Total solution mass = 23 g + 293 g = 316 g
Specific heat capacity of water = 4.18 J/Kg
The equation relating mass, heat, specific heat capacity and temperature change is:
q = mcΔT
197 kJ = 316 g x 4.18 J/Kg x ()
197 kJ = 316 g x 4.18 J/Kg x ( -298 K)
0.1491429956 x 1000 = -298 K
149.1429956 + 298 =
447.1429956 =
448 K =
Hence, 448 K is the final temperature of the water.
<h3>What does a high specific heat capacity mean?</h3>A high specific heat capacity means that it can store a large amount of thermal energy for a small change in mass or temperature.
