Answer:
soapy water is not good for plants irrigation that is what I learn
Solubility at 100 °C = 480 g / 100 mL of solution =: saturated solution
The proportion 240 g / 50 mL is equal to the saturated ratio 480 g / 100 mL
Then, 240 g of sugar in 50 mL of boiling water will make a saturated solution.
Answer: saturated
The statement correct about bonding is the release of energy in bond formation, and is exothermic. Thus, option C is correct.
The bonds have been defined as the sharing of electrons between atoms for the stabilization and forming compounds. The formation and breaking of the bond results in the absorption and release of the energy.
<h3>Endothermic and Exothermic reaction</h3>
The reaction in which the energy has been released has been termed as exothermic reaction. The reaction in which energy is absorbed is termed as endothermic system.
The bonds are stable, and to break the bond energy has to be provided to the system. The energy will result in the delocalization of electrons and thereby breaking of bonds.
Since energy has been absorbed by the system during breaking of bonds, the reaction has been an endothermic reaction.
The formation of the bond has been releases the energy in the system and is an exothermic reaction. Thus, option C is correct.

Answer:
seven on the ph scale is the neutral point
Explanation:
The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
Answer:
0.51M
Explanation:
Given parameters:
Initial volume of NaBr = 340mL
Initial molarity = 1.5M
Final volume = 1000mL
Unknown:
Final molarity = ?
Solution;
This is a dilution problem whereas the concentration of a compound changes from one to another.
In this kind of problem, we must establish that the number of moles still remains the same.
number of moles initially before diluting = number of moles after dilution
Number of moles = Molarity x volume
Let us find the number of moles;
Number of moles = initial volume x initial molarity
Convert mL to dm³;
1000mL = 1dm³
340mL gives 
= 0.34dm³
Number of moles = initial volume x initial molarity = 0.34 x 1.5 = 0.51moles
Now to find the new molarity/concentration;
Final molarity = 
= 
= 0.51M
We can see a massive drop in molarity this is due to dilution of the initial concentration.
