Does the reaction above satisfy the law of conservation of matter? Use details to support your work.

Physics

Leona [35]3 years ago

Answer:

No, the amount of matter of the reactants is not equal to the amount of matter of the products.

Explanation:

According to the conservation of matter the amount of matter of the reactants is equal to the amount of matter of the products. The given reaction is

2H_2O_2=H_2+O_2

In the reactant side there are 2\times 2=4 molecules of hydrogen and 2\times 2=4 molecules of oxygen.

In the product side there are 2 molecules of both hydgrogen and oxygen. So the reaction does not satisfy the law of conservation of mass.

The balanced reaction would be

2H_2O_2=2H_2+2O_2.

A block of aluminum measures 4.0 cm x 5.0 cm x 2.0 cm is completely immersed in a tank of water.
Aneli [31]

Answer:

upthrust or BUOYANT FORCE =Vdg

volume=LWH

upthrust=(4cm×5cm×2cm)×1g/cm²×g

upthrust=40cm³×1g/cm³×g

upthrust=40gf or 0.04kg×10m/s²=0.4N

weight of the displaced liquid is upthrust.

so mass=40g or 0.04kg

upthrust=40gf or 0.4Nand mass of the displaced liquid=40g or 0.04kg

What is the charge exchanged through contact ?
DIA [1.3K]
I was hoping that there would be some options to choose from in regards to this question. Since there are no options given, so i am giving the answer based on my knowledge and hope that it helps. The charge exchanged through contact is known as static charge of electrostatic charge. This charge is exchanged mostly through rubbing between two objects.

If the forces are equal and opposite why does the rocket ship move
qaws [65]
<span>A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. A good example of this is a balloon. Air inside a balloon is compressed by the balloon's rubber walls. The air pushes back so that the inward and outward pressing forces are balanced. When the nozzle is released, air escapes through it and the balloon is propelled in the opposite direction.</span>

A driver of a car traveling at 14.6 m/s applies the brakes, causing a uniform deceleration of 1.2 m/s2. How long does it take th
vfiekz [6]

Recall that

v_f=v_0+at

It takes the car about 3.2 s to reduce its speed from 14.6 to 10.8 m/s, since

10.8\,\dfrac{\mathrm m}{\mathrm s}=14.6\,\dfrac{\mathrm m}{\mathrm s}+\left(-1.2\,\dfrac{\mathrm m}{\mathrm s^2}\right)t\implies t=3.2\,\mathrm s

Next, recall that

\Delta x=x_f-x_0=\dfrac{v_f+v_0}2t

Then the car undergoes a displacement of about 41 m, since

\Delta x=\dfrac{10.8\,\frac{\mathrm m}{\mathrm s}+14.6\,\frac{\mathrm m}{\mathrm s}}2(3.2\,\mathrm s)\implies\Delta x=41\,\mathrm m
