Answer:
to reduce friction and increase efficiency of the machime
Answer: 1. 199.995 g of NaOH & 2. 2.014 g of H2
Explanation:
1. 5.00 mol H2O x __2 mol NaOH__ x __39.999 g__
2 mol H2O 1 mol
= 199.995 g of NaOH
2. 36 g H2O x __1 mol __ x __1 mol H2__ x __2.016 g__
18.016 g 2 mol H2O 1 mol H2
= 2.014 g of H2
Answer:
3-ethyl-4-methyl Heptane
Explanation:
longest chain is straight .
we start assigning number from where we are close to the branch to this mean its from left hand side. and we saw two chain 1 is ethyl and other is methyl . In alphabetical order e comes first as compare to m so we write ethyl first after that methyl and than in last we write longest chain name with ane (bcz we only have single vonds).
The chemical formula for formic acid is HCOOH or can also be CH202. Both work!
Hope this helps!
The correct option is ARGON.
To quickly find out the element that is been described by the electronic configuration, write down and add together all the index figures in the electronic configuration. The index figures in the above electronic configuration are 2, 2, 6, 2 and 6. If you add all these figures together, you will get 18 and the element that has the atomic number of 18 is argon.
