Answer:
Current
Explanation:
An electric fence used to contain cattle works by transmitting energy through a conductor creating an electric current.
An electric fence is usually connected to an electric power source . The connection brings about the flow of electric charges(current) which is aided by the presence of a conductor. The conductor ensures smooth flow of electric current to achieve the main purpose of the fence.
A combination reaction<span> is a </span>reaction<span> in which two reactants combine to form one product. It is also called a synthesis reaction. A characteristic to this type of reaction would be that there would always be only one product. Hope this answers the question. Have a nice day. </span>
<span>molar mass of MgCl2
= 24.32 + 2 x (35.45) = 95.22 g</span><span>
<span>16.4g MgCl2 x (1 mol MgCl2/95.22
g MgCl2) = 0.172 mol MgCl2 </span>
</span>
<span>0.172 mol MgCl2 x (6.022 x 10^23/1 mol
MgCl2) = 10.36 x 10^22 atoms<span> </span></span>
The model of the atom has dramatically changed over many many years.We learned atoms make up different substances and are the smallest particles of matter, which have subatomic particles that are very small portions of matter. At first scientist only thought there were electrons which are negatively charged.
