Answer:

An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements. In general, the size of an atom will decrease as you move from left to the right of a certain period.

Answer:

Passive transport

Explanation:

In Passive transport the energy is not essential in other for transportation to take place.it is in active transport where you see the need of energy for the process to take place.Passive transport involves the action of facilitated diffusion and osmosis.

8. The standard enthalpy of formation of RbF(s) is –557.7kJ/mol and the standard enthalpy of formation of RbF(aq, 1 m) is –583.8

garri49 [273]

Explanation:

Given

The enthalpy of formation of RbF (s) is –557.7kJ/mol

The standard enthalpy of formation of RbF (aq, 1 m) is –583.8 kJ/mol

The enthalpy of solution of RbF = Enthalpy of RbF (aq) - Enthalpy of formation of RbF (s)

= -583.8 - (-557.7) kJ/mol

= -26.1 kJ/mol

The enthalpy is negative which means that the temperature will rise when RbF is dissolved.

What is the molarity of a solution of 0.2 moles of Potassium Oxide

egoroff_w [7]

The molarity of a solution : 0.4 M

<h3>Further explanation</h3>

Given

0.2 moles of Potassium Oxide

500 ml of water = 0.5 L

Required

The molarity

Solution

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution

$\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}$

Assume volume of solution = volume of water(addition of solution volume from volume Potassium Oxide is negligible

Input the value :

M = 0.2 : 0.5

M = 0.4
