2H, +0,-> 2H,0 How many hydrogen atoms are on the left side of the equation?

Physics
1 answer:
marin [14]2 years ago
8 0

Answer:

4

Explanation:

The reaction between hydrogen and oxygen gives water (H2O)

2H,+O, -> 2H2O

Oxygen is a gas O, = O2

Balancing both sides

let , be x

2x = 4

x =  \frac{4}{2}

x= 2

Therefore, 2H2 = 4 hydrogen

An object has a kinetic energy of 14 J and a mass of 17 kg , how fast is the object moving?
lisabon 2012 [21]
v ^{2} = Joules ÷ (0.5×Kilograms)

14J ÷ 8.5 = 1.64705882

Remember, 1.64705882 = v², so we need to find the square root.

The square root of 1.64705882 is 1.283377894464448

Hope this helps!

Which description best matches the image below of a hand that is using the right-hand palm rule?
otez555 [7]

Answer:

When reviewing the results, the correct one is C

Explanation:

The right hand rule is widely useful in knowing the direction of force in a maganto field,

The ruler sets the thumb in the direction of the positive particle, the fingers extended in the direction of the magnetic field, and the palm in the direction of the force.

Let's apply this to our exercise.

The thumb that is the speed goes in the negative direction of the axis,

The two extended that the magnetic field look negative x,

The span points entered the dear sheet the negative the Z axis

When reviewing the results, the correct one is C

During an isothermal process, 10 j of heat is removed from an ideal gas. What is the work done by the gas in the process?
Black_prince [1.1K]

The work done in the isothermal process is 10 joule.

We need to know about the isotherm process to solve this problem. The isotherm process can be described as a process where the initial temperature system will be the same as the final temperature. Hence, the internal energy change will be zero.

ΔU = 0

Hence,

ΔU = Q - W

0 = Q - W

Q = W

It means that the heat transferred is the same as the work done.

From the question above, we know that the heat transferred is 10 joule. Thus, the work done in the isothermal process is 10 joule.
