A Hydration reaction is a chemical reaction in which a substance combines with water. Hope that helps!!
You would take mass/volume to find the density. So, 12.8/2^3 is 1.6. The density of the cube is 1.6.
Answer:
A. Right side since CO2 has has more entropy than solid CO2
B. Right side since gaseous CO2 is present on right side
C. Left side since more no of gaseous molecules om left side
D. Right side since on heating of water at 52C starts boiling hence more entropy for vapour.
Explanation:
Generally entropy is the measurement of randomness and follows the order gas>liquid>solid
Answer:
1.53 L
Explanation:
Step 1: Given data
- Mass of oxygen (m): 11.2 g
- Ideal gas constant (R): 0.0821 atm.L/mol.K
Step 2: Calculate the moles (n) corresponding to 11.2 g of oxygen
The molar mass of oxygen is 32.00 g/mol.
11.2 g × (1 mol/32.00 g) = 0.350 mol
Step 3: Calculate the volume of oxygen
We will use the ideal gas equation.
P × V = n × R × T
V = n × R × T / P
V = 0.350 mol × (0.0821 atm.L/mol.K) × 415 K / 7.78 atm
V = 1.53 L
Answer:
I think Sammy is right because I'm sure the compound contains ionic bonds
