Answer:

$HCO^-_3+HBrO\rightleftharpoons H_2CO_3+BrO^-$

Explanation:

Hello there!

In this case, according to the Brønsted-Lowry theory of acids, it is possible to realize that HBrO acts as the Brønsted-Lowry acid as it has a free hydrogen to give away to HCO₃⁻ which acts as the Brønsted-Lowry base able to accept the incoming hydrogen; therefore, the Brønsted-Lowry reaction is:

$HCO^-_3+HBrO\rightleftharpoons H_2CO_3+BrO^-$

Best regards!

What mass of melamine, c3n3(nh2)3, will be obtained from 113.0 kg of urea, co(nh2)2, if the yield of the overall reaction is 73.

creativ13 [48]

The balanced equation for the reaction is:

6 HNCO(l) → C3N3(NH2)3(l) + 3 CO2(g)

Convert amount of urea from kg to moles

Molar Mass of urea = 60.06 g/mol so, 113 kg urea contains

113 kg / 60.06 = 1.88 mol urea

From balanced equation 6 moles of urea yields only 1 melamine, so divide the moles of urea by 6.

1.88 / 6 = 0.313 kmol melamine

Now multiply 0.313 with molar mass of melamine that is 126 g/mol

126 x 0.313 = 39.438 kg

Yield of overall reaction is 73% so multiply 39.438 with 0.73

<span>39.438 x 0.73 = 28.799 kg is the answer</span>

If L = 5, then the magnetic quantum number "mL" can be equal to

Anit [1.1K]

b. -5, -4, -3, -2, -1, 0, +1, +2, +3, +4, +5

<h3>Further explanation</h3>

Each orbital in an atom consists of 4 quantum numbers

n is the principal quantum number.

l is the angular momentum / azimuthal quantum number

ml, the magnetic quantum number

ms, the electron-spin quantum number

Value of n: positive integer

value of l: s = 0, p = 1, d = 2, f = 3 , ..(n-1)

ml value: between -l to + l

ms value: +1/2 or -1/2

So for L=5, mL value : -5 to +5

Given the balanced equation representing a reaction:

2 and 3 are not possible because energy cannot be created nor destroyed. In order to break bonds, energy must be absorbed, so 1 is your answer!
