Light is helpful because it allows us to see things around us.
I hope this helps :)
Answer: C) Both are made up of monomers that are linked by covalent bonds
Explanation: Polymers are large molecules which are formed by combination of small repeating units called as monomers.
Natural polymers are found in nature such as cellulose whereas synthetic polymers are synthesized in laboratories such as Nylon 6,6.
All the polymers, whether natural or synthetic are made up of monomers and are joined by covalent bonds.
Hey there!
Molar mass of nitrogen is 14.007 g.
We have 7 moles.
Multiply 7 by 14.007.
7 x 14.007 = 98.049
7 moles of nitrogen has a mass of 98.049 grams.
Hope this helps!
Answer:
Equation 2, because K being more reactive, exchanges position with Pb in PbNO3.
Explanation:
For electricity to flow there must be a flow of electrons or ions present in a system or medium. When electricity is passed in pure water, oxygen does not have d-orbitals or f-orbitals through which electrons may pass. In pure water there are no electrolytic substance, so no ions present in the pure water. Therefore electricity can not pass through pure water. Additionally; water cannot dissociate into OH- and H+ when electricity is passed through pure water.
