Disinfectants are chemicals in liquid form which destroy micro organisms. They are usually applied to the surfaces of non-living objects in order to kill microbes that are located on those surfaces. Disinfectants are usually used in the hospitals, kitchens, bathrooms, etc to kill infectious microbes. There are different types of disinfectants and the choice of the type to use depends on the kind of microbes involved. Disinfectants are used when there is a possibility that a surface has been infected with infectious agents.
Answer:
b. Conducts electricity when dissolved in water
Explanation:
Iron(II) chloride, is the chemical compound with formula FeCl2.
It is a solid with a high melting point of about 677 degree Celsius or 950 K when in anhydrous form but have lower melting point in hydrated form.
The compound is often off-white. FeCl2 crystallizes from water as the greenish tetrahydrate, which is the form that is most commonly encountered in the laboratory.
There is also a dihydrate. The compound is highly soluble in water, giving pale green solutions.
Hydrogen bonds allow water molecules to link together x
Answer : The specific heat of the metal is, 
Explanation
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of metal = ?
= specific heat of water = 
= mass of metal = 95.0g
= mass of water = 50.0 g
= final temperature of mixture = 
= initial temperature of metal = 
= initial temperature of water = 
Now put all the given values in the above formula, we get
![(95.0g)\times c_1\times (48.5-100.0)^oC=-[(50.0g)\times 4.18J/g^oC\times (48.5-22.5)^oC]](https://tex.z-dn.net/?f=%2895.0g%29%5Ctimes%20c_1%5Ctimes%20%2848.5-100.0%29%5EoC%3D-%5B%2850.0g%29%5Ctimes%204.18J%2Fg%5EoC%5Ctimes%20%2848.5-22.5%29%5EoC%5D)
Therefore, the specific heat of the metal is,
The carbon atom would be positively charged because there is more protons then electrons. Their is an equal amount of electrons and protons thus, taking an electron away makes it positively charged ion.
