It was a spring morning of April 16, 1947, was a morning that many citizens of Texas City thought was the end of the world. The French Liberty ship, SS Grandcamp, bearing a cargo of ammonium nitrate fertilizer (over 2300 tons) destined for war-torn Europe, caught fire in the Texas City harbor. The bright ... A little after 9.00 a.m., the Texas City Disaster (as it is popularly known) occurred as the ship Grandcamp exploded.

Complete the electron-dot structure of s-allylcysteine, showing all lone-pair electrons.

erastova [34]

The structural formula of <span>s-allylcysteine is shown in the picture (top figure). To create its Lewis structure, draw all its bonds between elements. Each single bond contains two electrons. There is an octet rule that must be obeyed by most elements. Each element should be surrounded with 8 electrons. The hydrogen is exempted of this rule. So, there are 4 lone pairs for the S atom, 1 lone pair for the N atom, and 2 lone pairs each for the 2 O atoms.</span>

What happens to the rate of a reaction as the reaction progresses?

ZanzabumX [31]

Answer:

D. The rate decreases as reactants are used up.

Explanation:

Initially, the rate increases until the reaction is at equilibrium. At equilibrium, the rate is constant.

As the reaction progresses, the rate decreases to zero when reactants are used up ( for irriversible reactions only )

g Suppose a sample of an ideal gas in a container is subjected to a temperature change. A decrease in temperature will the kinet

Umnica [9.8K]

Answer:

323.15 °C

Explanation:

Considering the ideal gas equation as:

$PV=nRT$

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = 0.0821 L.atm/K.mol

Thus, at constant volume and number of moles, Pressure of the gas is directly proportional to the temperature of the gas.

P ∝ T

Also,

Using Charle's law

$\frac {P_1}{T_1}=\frac {P_2}{T_2}$

Given ,

P₂ = 2P₁

T₁ = 25 °C

T₂ = ?

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T₁ = (25 + 273.15) K = 298.15 K

Using above equation as:

$\frac{P_1}{298.15}=\frac{2P_1}{T_2}$

$T_2=2\times 298.15\ K$

New temperature = 596.3 K

Also,

T(K) - 273.15 = T( °C)

<u>So, Temperature = 596.3 - 273.15 °C = 323.15 °C</u>

What is the pH of a solution that has [H+] of .0042M?

sveticcg [70]

Answer:

pH = 2.4

Explanation:

pH is defined as the negative log of the hydronium concentration.

Thus, we can plug in the given hydronium concentration:

pH = -log[H⁺] = -log[0.0042] = 2.4 (two significant figures)

The pH of the solution is 2.4.

P.S: Although I referred to [H⁺] as hydronium concentration, it is more accurate to express it as [H₃O⁺], though they are interchangeable and means the same thing.
