Many household cleaners, particularly toilet cleaners and some drain cleaners have acid in them. This is the equation representi

ng hydrochloric acid plus bleach. NaClO + 2 HCl →Cl2 + H2O + NaCl If you mix bleach with acidic cleanser, a very noxious gas that can cause respiratory problems will be released. Your sense of smell can detect this gas in air at concentrations as low as 0.08 parts per million and at that level, it is basically an irritant. Levels as low as 15 parts per million can cause severe throat irritation while levels of 50 parts per million or above are very dangerous. What is this gas?

Answer:

The gas is chlorine gas.

Explanation:

NaClO + 2 HCl \rightarrow Cl_2 + H_2O + NaCl

Chlorine gas is a toxic gas and very reactive inside the human body. Also an irritant to eyes and skin. Exposure to high concentration leads to lung damage or death.

Where as the byproduct formed are water and sodium chloride which an aqueous solution of sodium chloride harmless to humans.

At its closest approach, a moon comes within 200,000 km of the planet it orbits. At that point, the moon is 300,000 km from the
krok68 [10]

Answer:

s₁ = 240,000 km

Explanation:

The distance between both the focuses f₁ and f₂ will be the sum of distances of the moon from each focus at a given point. Therefore,

s = s₁ + s₂

where,

s = total distance between the focuses = ?

s₁ = distance between f1 and moon = 200,000 km

s₂ = distance between f₂ and moon = 300,000 km

Therefore,

s = 200,000 km + 300,000 km

s = 500,000 km

Now, when the distance from f₂ becomes 260,000 km, then the distance from f₁(planet) will become:

s = s₁ + s₂

500,000 km = s₁ + 260,000 km

s₁ = 500,000 km - 260,000 km

<u>s₁ = 240,000 km</u>

Describe the relationship between the length and period of a pendulum in the language of direct proportions
Wittaler [7]

The period of the pendulum is directly proportional to the square root of the length of the pendulum

Explanation:

The period of a simple pendulum is given by the equation

T=2\pi \sqrt{\frac{L}{g}}

where

T is the period

L is the length of the pendulum

g is the acceleration of gravity

From the equation, we see that when the length of the pendulum increases, the period of the pendulum increases as the square root of L, T\propto \sqrt{L}. This means that

The period of the pendulum is directly proportional to the square root of the length of the pendulum

From the equation, we also notice that the period of a pendulum does not depend on its mass.

Explain why astronomers long ago believed that space must be filled with some kind of substance (the “aether”) instead of the va
professor190 [17]

Answer:Explained

Explanation:

The scientist of that time could not believe that the electromagnetic waves do not require a medium to travel through so they made a space filling substance necessary to travel of electromagnetic waves called aether.

But after the special 0 theory of relativity this idea is discarded and fell out.
