It controls activities that are not under your control so it’s true
Answer:
100 g
Explanation:
We know the concentration is 200 g/L.
Convert 500mL to L: 500mL/1000mL = 0.5 L
Now, multiply this by 200 to cancel out the L units and get grams:
200 g/L * 0.5 L = 100 g
Thus, the answer is 100 grams.
Hope this helps!
A polar molecule is a molecule whose ends have opposite electric charges. An example of a polar molecule is H2O or water. Water has 1 side which is positive and the other side which is negative. It is a dipole which means that the two sides are not having the same charges.
Answer:
addition polymerization
Explanation:
In addition polymerization, the monomers are simply joined to each other to form a polymer having the same empirical formula as the monomer but of higher relative molecular mass. The monomers in addition polymerization are usually simple unsaturated molecules such as alkenes.
We can deduce the reaction to be an addition polymerization because of the the attachment of n to both the unsaturated monomer and the saturated polymer without the loss of any small molecule. If it was a condensation polymerization, there would have been an accompanying loss of a small molecule such as water.
The chemical formula is MgF2 as mg looses two electrons and fluorine gains one. Therefore you need two fluorides to gain two electrons
