Write the chemical formula for sodium hypobromite.

irga5000 [103]

Answer:

NaOBr (or) Na⁺ ⁻OBr

Explanation:

The Oxo-Acids of Bromine are as follow,

Hypobromous Acid = HOBr

Bromous Acid = HOBrO

Bromic Acid = HBrO₃

Perbromic Acid = HBrO₄

When these acids are converted to their conjugate bases their names are as follow,

Hypobromite = ⁻OBr

Bromite = ⁻OBrO

Bromate = ⁻OBrO₂

Perbromate = ⁻OBrO₃

According to rules, the positive part of ionic compound is named first and the negative part is named second. So, Sodium Hypobromite has a chemical formula of Na⁺ ⁻OBr or NaOBr.

Sally has constructed a concentration cell to measure Ksp for MCln. She constructs the cell by adding 2 mL of 0.05 M M(NO3)n to

hram777 [196]

Answer:

0.1056 mole

Explanation:

As Sally knows that the charge on the metal ion is n = +2

$MCl_n=MCl_2$

In that compartment $[M^{n+}]=[m^{2+}]=8.279 \ M$

The volume of the $MCl_n$ taken in that compartment = 6.380 mL

So, the number of moles of $M^{2+} = 8.279 \times 6.380$

= 52.82 m mol

= 0.05280 mol

$MCl_n \rightarrow M^{n+}+nCl^-$

But n = 2

Therefore, moles of $Cl^-$ = 2 x moles of $M^{n+}$

= 2 x 0.05282

= 0.1056 mole

Write the balanced nuclear equation for β− decay of silicon−32. Include both the mass numbers and the atomic numbers with each n

weqwewe [10]

Answer:

$^{32}_{14}Si\rightarrow ^{32}_{15}P+e^-+\bar{v}_e$

Explanation:

Beta decay conserves the lepton number. In $\beta^-$ decay, the atomic number of the element increases which is accompanied by the release of an electron antineutrino, $e^-+\bar{v}_e$ .
