Answer:
An alternative to this could be 70 isopropyl alcohol. Potassium iodide is what is used to iodize salt, protect the thyroid gland from radioactive iodine, and via a pill taken by mouth treats low iodine levels (especially in the developing world). An alternative to this could be non-iodized salt.
Explanation:
Hope this helps.
Answer:
Elements with low ionization energies.
Explanation:
The ionization energy of an atom reffers to the amount of energy that is required to remove an electron from the gaseous form of that atom or ion.
The greater the ionization energy, the more difficult it is to remove an electron. The ionization energybis one of the indicator that shows the reactivity of an element. Elements with a low ionization energy such as metals are usually reffered to as a reducing agents and form cations, this give metals the tendency to
give away their valence electrons when bonding, whereas non-metals tend to take electrons.
Metallic elements have different properties such as shiny, heat and electricity conductivity . They are malleable and ductile Some metals, such as sodium, are soft and can be cut with a knife. while some are very hard such as iron.
Answer:
d. may melt if heat is transferred to it from hot mantle rock rising up into the crust.
Explanation:
Hot, solid rock in the Earth's crust is a solid outer region of the Earth, Underneath the Earth Structure lies the mantle which is composed of solid rocks especially granite and basalt. The mantle is very hot and may melt if heat is transferred to it from hot mantle rock rising up into the crust therefore forming a molten magma. It may even be hotter (and not cooler as it was stated in the option A which makes it the wrong answer) than the surface lava because of the pressure of the overlying rock. As such, This effect is seen when a volcanic eruption occurs.
The given units are the units of masses which are interconvertable.
It is given that:
Now, converting 
:
Since, 
So, 
Now converting 
:
Since, 1 kg = 1000 g
So, 
For 
:
Thus, 
of ointment needed to be prepared by the pharmacist.
