Answer:
K= 25.16%
Mn= 34.59%
O= 40.25%
Explanation:

Find the total mass of the compound. You can do this by multiplying by the molar mass.

add them:
40+55+64=159g
Now convert each element individually to grams using molar mass



Divide by the mass of the compound and multiply by 100



We have to determine if the given compound is soluble or insoluble in water.
The given compound is copper (II) hydroxide,
. According to the solubility rules the hydroxides of all metal ions are insoluble except that of ammonium and the alkali metal ions. So copper(II) hydroxide will be insoluble in water. In aqueous solution, copper (II) hydroxide would exist as a sparingly soluble compound in which the undissociated compound remains in equilibrium with the ions
and
. The equilibrium would remain mostly towards undissociated form.

Therefore,
is insoluble in water.
The answer is land because land absorbs heat more quickly but it also loses heat more quickly. And it is not water because water is a low conductor of heat and water has to lose more energy in order for the temperature to decrease. And air could not be the answer.
Answer:
The patient will be taking medicine for 14 days.
Explanation:
Volume of PO amoxicillin in multi-dose bottle = 336 mL
Volume of dose taken by patient in a 1 day = 24 mL
If the patient will be consuming whole volume of PO amoxicillin in multi-dose in x days.Then:


x = 14 days
The patient will be taking medicine for 14 days.
Bond pair is simply a pair of electron which is being shared mutually between two atoms forming a chemical bond or in other words, it means the electron density lies in between two atoms.
