C4H10 (g) + (6.5) O2 (g) --> 4CO2 (g) + 5H2O (g)
Smallest coefficient of C4H10 is 1.
First, balance out the Carbon and Hydrogen atoms as they are limiting.
Second, calculate the number of Oxygen atoms and minus away those found in C4H10.
Divide the number with 2 as oxygen exists as O2. [It is OK to put a fraction in front of the molecule as long as there is 1 atom used in the reaction. ]
Answer:
these answer choices are extremely confusing to read lol.
so the answer is 125lb x 16oz/1lb x 28g/1oz x 1kg/1000g

Answer:
There are there are 8.13-10^25
Explanation:
N(CS2)= 1.35* (times) 6.02-10^ 25= 3.13-10^25 molecules
Answer:
C. He
Explanation:
When lithium is ionized, its new electronic configuration is the same as that of a helium atom.
Lithium is made up of 3 electrons with a configuration of:
2, 1
it has 1 electron in its outermost shell.
As a metal lithium will prefer to lose an electron due to its electropositivity.
On losing an electron, it will have 2 electrons remaining
Now, Helium has 2 electrons and this makes it similar to Lithium that has lost one electron.
This makes Lithium isoelectronic with Helium.
