Answer:

It has been approximately 6 hours after death.

Explanation:

This is because between 2-6 hours after death, the body starts becoming stiff from top to bottom, then spreading to the limbs. Since there is only rigor in his upper body, that would mean that with normal temperature and body conditions, it would be 4 or 5 hours after death. But since he is obese and in cold temperature, there is slower progression of rigor, leading to the maximum time in the first rigor mortis phase, 6 hours.

At 500°C the equilibrium constant, Kp, is 4.00 × 10–4 for the equilibrium: 2HCN(g) H2(g) + C2N2(g) What is Kp for the following
Andrews [41]

<u>Answer:</u> The value of K_p for the equation is 2.5\times 10^3

<u>Explanation:</u>

The given chemical reaction is:

2HCN(g)\rightleftharpoons H_2(g)+C_2N_2(g);K_1

The chemical equation for which the equilibrium constant is to be calculated follows:

H_2(g)+C_2N_2(g)\rightleftharpoons 2HCN(g);K_p

As, the equation is the result of the reverse of given reaction. So, the equilibrium constant for the equation will be the inverse of equilibrium constant for the given reaction.

The value of equilibrium constant for the equation is:

K_p=\frac{1}{K_1}

We are given:

K_1=4.00\times 10^{-4}

Putting values in above equation, we get:

K_p=\frac{1}{4.00\times 10^{-4}}=2.5\times 10^3

Hence, the value of K_p for the equation is 2.5\times 10^3

Select all the statements that correctly describe the chair conformation of cyclohexane. Multiple select question. The bond angl
Yuki888 [10]

All the statements except Option D is true for the chair confirmation of cyclo hexane.

<h3>Describe the Chair confirmation of Cyclohexane  ?</h3>

The flexibility of Cyclo hexane allows for formation of a confirmation ,

This confirmation has lowest energy among the confirmations that can be made for Cyclohexane.

The bond angles are near 109.50 degree,

Each carbon atom has one axial and one equatorial hydrogen atom and All hydrogen atoms on adjacent carbon atoms are staggered.

Therefore Option A , B , C are all true statements about the Chair Confirmation of Cyclohexane.

Determine the mass in grams of 5.15 × 10²¹ atoms of chromium. (The mass of one mole of chromium is 52.00 g.)
Dennis_Churaev [7]

The mass of 5.15 × 10²¹ atoms of chromium is 0.44 g

From Avogadro's hypothesis,

6.02×10²³ atoms = 1 mole of Cr

But:

1 mole of Cr = 52 g

Thus, we can say that:

6.02×10²³ atoms = 52 g of Cr

With the above information, we can obtain the mass of 5.15 × 10²¹ atoms of chromium. This can be obtained as follow:

6.02×10²³ atoms = 52 g of Cr

Therefore,

5.15×10²¹ atoms = (5.15×10²¹ × 52) / 6.02×10²³

5.15×10²¹ atoms = 0.44 g of Cr

Thus, the mass of 5.15 × 10²¹ atoms of chromium is 0.44 g
