.176 M. This is established by equating the moles of the base with the moles of the acid. (1.008 mol/L)(26.23 x 10^-3 L)=(150.2x10^-3 L)(x) x =.176030892 mol/L.

On occasion, it has been found that the oxidation of borneol doesn't go to completion (possibly because of poor stirring or insu
VMariaS [2675]

Response:

Examine the explanation

Explanation:

In this scenario, Nitrogen (N) experiences oxidation while Chlorine (Cl) undergoes reduction.

In response to your inquiry:

N is oxidized from an oxidation state of -3 to -1.

Cl is reduced from an oxidation state of +1 to -1.

At this point,

Borneol will likely exhibit a lower Rf due to its boiling point.

A magnesium ion, Mg2+, with a charge of 3.2×10−19C and an oxide ion, O2−, with a charge of −3.2×10−19C, are separated by a dista
eduard [2509]

Details:

The equation to calculate work done is defined as follows.

W = -k \frac{q_{1}q_{2}}{d}

where, k = proportionality constant = 8.99 \times 10^{9} Jm/C^{2}

q_{1} = charge of Mg^{2+} = 3.2 \times 10^{-19} C

q_{2} = charge of O_{2-} = -3.2 \times 10^{-19} C

d = separation distance = 0.45 nm = 0.45 \times 10^{-9} m

Now we will insert the given values into the formula above to compute the work done as follows.

W = -k \frac{q_{1}q_{2}}{d}

= \frac{-[8.99 \times 10^{9} Jm/C^{2} \times 3.2 \times 10^{-19} C \times -3.2 \times 10^{-19} C]}{0.25 \times 10^{-9} m}

= 3.68 \times 10^{-18} J

Thus, we can conclude that the work needed to increase the distance between the two ions to infinity is 3.68 \times 10^{-18} J.

A laboratory analysis of an unknown sample yields 74.0% carbon, 7.4% hydrogen, 8.6% nitrogen, and 10.0% oxygen. What is the empi
Tems11 [2387]
Assuming we have a 100g sample, the mass of each element is as follows:
C: 74 g
H: 7.4 g
N: 8.6 g
O: 10 g
Next, we calculate the moles of each by dividing the mass of each element by its molar mass:
C: (74 / 12) = 6.17
H: (7.4 / 1) = 7.4
N: (8.6 / 14) = 0.61
O: (10 / 16) = 0.625
Now, we take the smallest value to determine the ratio:
C: 10
H: 12
N: 1
O: 1
Thus, the empirical formula can be expressed as
C10H12NO

Suppose a 20.0 g gold bar at 35.0°C absorbs 70.0 calories of heat energy. Given that the specific heat of gold is 0.0310 cal/g °
VMariaS [2675]

The change in temperature can be expressed as:

T_2-T_1=\dfrac{q}{mC_p(Gold)}

By substituting in the known values, we arrive at:

T_2-T_1=\dfrac{70\ cal}{20\ g\times 0.0310\ cal/g^o\ C}\\\\T_2-T_1=112.90^oC\\\\T_2-35^oC=112.90^oC\\\\T_2=(112.90+35)^oC\\\\T_2=147.9^oC

Thus, we obtain the required answer.
