Fusion. In the mid 1930s,Enrico Fermi bombarded uranium with thermal neutrons and observed the release of a large amount of energy. This happened because the heavy uranium nucleus split unto two lighter nuclei, releasing two or three neutrons.

Hope this helps :))

Write the iupac name for the compound below. be sure to use correct punctuation.

CaHeK987 [17]

I can't answer this question if the structural formula is not given. However, I found a similar problem in terms of wording. Taking this problem to be solved, let's take a look at the structural formula as shown in the second picture. First, you must know the parent chain, which is the longest chain. This is a trial-and-error process. The longest chain which has a branching group that is nearest to the head is the correct numbering. In this case, the longest chain has 8 carbon atoms. Thus, the base of the name if octane. Because a 3-carbon chain is branching from the 4th carbon, the IUPAC name of the compound shown is: 4-propyloctane.

You have 2 moles of NaOH how many molecules of NaOH?

kaheart [24]

Answer:

12.044 X 10^23 molecules of NaOH

Explanation:

because NaOH is an ionic bond, we should be asking how many formula units are in 2 moles of NaOH, there are 0 molecules since NaOH is measured in formula units.

but for the sake of the problem I'll assume NaOH is measured in molecules

for every mol of something there are 6.022 X 10^23 of something of that something.

so there are 6.022 X 10^23 molecules for every mol of NaOH

that means we have 2 X 6.022 X 10^23 molecules in 2 moles of NaOH = 12.044 X 10^23 molecules of NaOH

The hybridization for the B in Bcl3 is ?

Phoenix [80]

Answer:

sp²

Explanation:

You need to look at how many electron orbitals around the atom. Looking at the structure below, you can see that there are three electron orbitals. This gives you an sp² hybridization.
