Answer:

The final temperature is 806.226 degrees celcius.

Explanation:

It is given that initial conditions are as follows,

<em>Initial volume = 425 ml</em>

<em>Initial temperature =- 12 degrees celcius = 261 K</em>

<em>Initial pressure =788 mmHg</em>

The final conditions are as follows,

<em>Final volume = 2.4 liters</em>

<em>Final pressure = 577 mmHg</em>

<em>Final temperature = "T"</em>

<em>Let R be universal gas constant, n be number of moles..</em>

The ideal gas equation, is as follows,

(pressure)(volume) = (number of moles)(R)(temperature)

The number of moles remain constant in the process,

so equating <em>initial number of moles = final number of moles</em> , we get

\frac{(788)(425)(10^{-3}}{261} = \frac{(577)(2.4)}{T}

T = 1079.226 K = 806.226 degrees celcius

For each equation , write all possible mole ratios . A. 2HgO(s)&gt;2Hg(l)+O2(g) B. 4NH3(g)+6NO(g)&gt;5N2(g)+6H2O(l)
Dafna11 [192]

A) For balanced chemical equation: 2HgO(s) → 2Hg(l) + O₂(g).

1) Mole ratio 1: n(HgO) : n(Hg) = 2 : 2 (1 : 1).

2) Mole ratio 2: n(HgO) : n(O₂) = 2 : 1.

3) Mole ratio 3: n(Hg) : n(O₂) = 2 : 1.

B) Balanced chemical equation: 4NH₃(g) + 6NO(g) → 5N₂(g) + 6H₂O(l).

1) Mole ratio 1: n(NH₃) : n(NO) = 4 : 6 (2 : 3).

2) Mole ratio 2: n(NH₃) : n(N₂) = 4 : 5.

3) Mole ratio 3: n(NH₃) : n(H₂O) = 4 : 6 (2 : 3).

4) Mole ratio 4: n(NO) : n(N₂) = 6 : 5.

5) Mole ratio 5: n(NO) : n(H₂O) = 6 : 6 (1 :1).

6) Mole ratio 6: n(N₂) : n(H₂O) = 5 : 6.

What is the relationship between mass and gravity
Tpy6a [65]

Answer:

since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
