Sr is the atom that has the lower ionization energy.
Ionization is the procedure by using which ions are shaped by the gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it will become definitely charged (a cation). energy may be misplaced or received within the formation of an ion.
Ionization or Ionisation is the manner by means in which an atom or a molecule acquires a negative or superb price through gaining or dropping electrons, regularly along with other chemical modifications. The resulting electrically charged atom or molecule is referred to as an ion.
while sodium and chlorine integrate to make salt, the sodium atom offers up an electron resulting in a wonderful charge, while chlorine receives the electron and will become negatively charged as an end result.

The value is 
Explanation:
From the question we are told that
The mass of saxitoxin is 
The volume of water is 
The osmotic pressure is 
The temperature is 
Generally the osmotic pressure is mathematically represented as
Here R is the gas constant with value
and C is the concentration of saxitoxin
So
Generally the number of moles of saxitoxin is mathematically represented as
=> 
=> 
Generally the molar mass of saxitoxin is mathematically represented as

Answer:
Every 15 degrees is an hour
Explanation:
What is the time difference in mean solar time between 30° N 75° W and 30° N 90° W?
Answer:
14 J of heat
Explanation:
Recall that the enthalpy of reaction is defined as the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, if all reactants and products are in their standard states. Here we have the heat of formation of six moles of the substance and we are expected to use it to obtain the the heat of formation of one mole of the compound and we can do that by simple proportion as shown below;
If 6 moles of the compound produces 84J of heat
1 mole of the substance will produce 1×84/6 = 14 J of heat
