Answer:

Kr

Explanation:

The noble gas that is isoelectronic with Br⁻ is krypton.

This is because krypton is the closest noble gas to Br on the periodic table.

Electronic configuration of Bromine is;

            2, 8, 18, 7

  Br⁻ becomes;  2, 8, 18, 8

  Krypton is;       2, 8, 18, 8

Pls help!!! Write asap!! <br> How many moles of sulfur are there if you have 0.994g of sulfur
timama [110]

To convert weight to moles, we must use the molar weight found on the periodic table. Sulfur's (S) molar weight is 32.06 g/mol. Then we set up an equation and cancel out units:

\frac{1mole}{32.06g}*0.994g=0.031mol=3.1*10^{-2}mol

So now we know that 0.994g of sulfur is equal to 0.031 moles.

Which of the following is the correct order of steps in translation?
n200080 [17]

Answer:

4,2,1,3

Explanation:

4. A small ribosomal subunit binds to a molecule of mRNA5. the anticodon of an incoming aminoacyl tRNA base-pairs with the complementary mRNA codon in the A site.

2. The large ribosomal subunit attaches with the initiator tRNA with the amino acid methionine (Met) located in the P site.

1. The ribosome translocates the tRNA in the A site to the P site and the empty tRNA in the P site is moved to the E site where it is released.

3. A release factor, a protein shaped like an aminoacyl tRNA, promotes hydrolysis and releases the polypeptide.

Write a balanced chemical equation for the reaction that occurs when silver (I) oxide decomposes into silver metal and oxygen ga
PolarNik [594]

Explanation:

The grey powder of silver ( I ) oxide i.e.  Ag₂O  breaks down to give a metal called the silver metal and an odorless , colorless gas , which is the oxygen gas .

The balanced chemical reaction is as follows -

Silver oxide ----->  Silver + oxygen

Ag₂O   ------>   Ag  (s)  +  O₂  (g)

The balanced reaction is -

2 Ag₂O (s)  ------>  4 Ag  (s)  +  O₂  (g)

Which gas makes your voice deeper or has the opposite effect on you than helium when you inhale it.
slega [8]
The correct answer is Sulfur Hexafluoride
it’s an inert gas that is known to be six times heavier than the air we breathe. While Helium being lighter makes our voice higher, SF6 makes our voice deeper. The sound travels slower in denser gases which is why our voice will come out deeper and rather slow.
