When the amount of gas in a container is increased, the volume increases. Lussac's law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
Answer:
High activation energy is the reason behind unsuccessful reaction.
Explanation:
There are two types of reaction: (1) thermodynamically controlled reaction and (2) kinetically controlled reaction.
Thermodynamically controlled reaction are associated with change in enthalpy during reaction. More negative the enthalpy change, more favored will be the reaction.
Kinetically controlled reaction are associated with activation energy of a reaction. The lower the activation energy value, the more rapid will be the reaction.
Here, reaction between and is thermodynamically favored due to negative enthalpy change but the high activation energy does not allow the reaction to take place by simple mixing.

Explanation:
A net ionic equation shows only the chemical species that are involved in a reaction, while a complete ionic equation also includes the spectator ions(Khan Academy).
From the species shown in the image we can write the molecular equation, ionic equation and net ionic equation and also identify the spectator ions.
Chemical equation: KX + BY --------> BX + AY
Ionic Equation; X^- + A^+ + B^+ + Y^- -----> BX + A^+ + Y^-
Spectator ions; A^+ and Y^-
Net Ionic Equation; X^- + B^+ ------> BX
Answer: 37.0 °C , 42.5 °C
Explanation:
Answer:
Drip rate = 2 ml/h
Explanation:
Given:
Amount of insulin = 500 unit
Amount of saline = 250 ml
Required infusion rate = 4.0 units/h
Find:
Drip rate
Computation:
Concentration = Units of insulin / Volume of saline
= 500 / 250
Concentration = 2 units/ml
Drip rate = Infusion rate / concentration
Drip rate = 4 / 2
Drip rate = 2 ml/h
