Answer:

See explanation

Explanation:

Calcium carbide reacts with water to yield acetylene gas and calcium hydroxide as follows;

CaC2(s)+2H2O(g)⇋Ca(OH)2(s)+C2H2(g)

This now shows us that the equation as written in the question is wrong. Since the equation for the reaction of calcium carbide and water as shown in the question is wrong, the equation can not be balanced.

If we accelerate a radioactive isotope of an element in a particle accelerator to a speed close to that of light, what would its
Radda [10]

When the speed of the particle is close to that of light, it's observed mass would be infinitely large.

To answer the question, we need to know what observed mass is.

<h3>What is observed mass in relativity?</h3>

This is the mass the body of an object in relativistic motion appears to have.

So, observed mass, m' = m/√(1 - β²) where

  • m = rest mass and
  • β = relative velocity of isotope to light.

Now, since the speed of the particle is close to that of light, β ≅ 1.

So, m' = m/√(1 - β²)

m' = m/√(1 - 1²)

m' = m/√(1 - 1)

m' = m/√0

m' = m/0

m' = ∞

So, when the speed of the particle is close to that of light, it's observed mass would be infinitely large.
