Answer : The correct option is, (1) P_4O_6(s)+2O_2(g)\rightarrow P_4O_{10}(s)

Explanation :

The two intermediate chemical equations are :

P_4O_6(s)\rightarrow P_4(s)+3O_2(g)     ..............(1)

P_4(s)+5O_2(g)\rightarrow P_4O_{10}(s)    .............(2)

Now adding equation (1) and equation (2), we get

P_4O_6(s)+P_4(s)+5O_2(g)\rightarrow P_4(s)+3O_2(g)+P_4O_{10}(s)

Now we will cancel the P_4(s) from both the sides of the equation, we get

P_4O_6(s)+5O_2(g)\rightarrow 3O_2(g)+P_4O_{10}(s)

Now we will subtracting 3O_2(g) from the 5O_2(g), we get

P_4O_6(s)+2O_2(g)\rightarrow P_4O_{10}(s)

This is the final chemical equation.

20 N force moving a box to 30 meters distance. How much work id done? if it takes 10 sec to do this work, how much power is used
dalvyx [7]

Answer:

Work done = 600 J

Power used = 60 W

Explanation:

Given:

Force acting on the box is, F=20\ N

Displacement of the box is, S=30\ m

Time taken for the work, t=10\ s

Now, we know that, work is said to be done by a force only when there is displacement caused by the force in its direction.

Here, the force acting on the box causes a displacement of 30 m in its direction. So, work done is equal to the product of force and displacement caused.

Therefore, work done on the box is given as:

Work=Force\times Displacement\\Work=F\times S\\Work=(20\ N)\times (30\ m)\\Work=600\ J

Therefore, the work done is 600 J.

Now, we know that, power is given as work done per unit time.

So, power used is given as:

Power=\frac{Work}{Time}\\\\Power=\frac{600\ J}{10\ s}\\\\Power=60\ W

Therefore, the power used is 60 W.

Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pr
Delvig [45]
<h2>Hello!</h2>

The answer is: Charle's Law.

<h2>Why?</h2>

The law that states that the volume and absolute temperature of a fixed quantity of gas (ideal gas) are proportional under constant pressure is the Charle's Law, also known as the law of volumes.

The law describes how a gas kept under constant pressure tends to expand when the temperature increases and it's described by the following equation:

\frac{V}{T}=k

Where,

V=Volume\\T=Temperature\\k=constant

Also, to describe the relationship between two differents volumes at different temperatures, we have:

\frac{V_{i}}{T_{i}}=\frac{V_{f}}{T_{f}}

Where,

V_{i}=InitialVolume\\T_{i}=InitialTemperature\\V_{f}=FinalVolume\\T_{f}=FinalTemperature

Have a nice day!
