Answer:

I think C)

Explanation:

The reason for this is due to the phenomenon called "Charging by Induction". What that means is that when something with a charge, for example a negative charge, is brought near an uncharged one, it induces the opposite charge onto it (positive in this case) and therefore since opposites attract, it attracts it.

The reason for this is that since, just like a positive magnet rejects and pushed away like charges, the electrons hold a negative charge, they push away any electrons that may be in the neutrally charged item causing only protons to be left, thus creating an oppositely charged object. Or vice versa.

So whatever charge the object has, it induces the opposite charge into the uncharged object, causing the charges to move only in the uncharged one.

Describe the relationship between volume and temperature of an ideal gas

kvv77 [185]

Answer:

Explanation:

Here, we want to describe the relationship between the volume and temperature of an ideal gas

This relationship is defined by Charles' law

From this law, we know that the volume of a given mass of gas is directly proportional to its temperature at a fixed pressure

What this means is that as long as the pressure remains unchanged, when the volume increases, the temperature increases, and when the volume decreases, the temperature decreases

These can be represented by the mathematical formula below:

$\frac{V_1}{T_1}\text{ = }\frac{V_2}{T_2}$

Complete Question

The complete question is shown on the first uploaded image

Answer:

The partial pressure is $P_p= 737.5 mm \ of \ Hg$

Explanation:

The Partial pressure of $H_2$ is mathematically represented as

$P_p = P_T -P_w$

Where $P_T$ is the total pressure of water with a value of 15.5 mm of Hg

$P_w$ is the partial pressure of water with a value 753 mm of Hg

Now substituting values

$P_p = 753-15.5$

$P_p= 737.5 mm \ of \ Hg$

Marrrta [24]

Answer:

2H⁺ + NO₃⁻ + 1e⁻ → NO₂ + H₂O

Explanation:

NO₃⁻ → NO₂

In left side, Nitrogen acts with +5 by oxidation number

In right side, the oxidation number is +4

This is a reduction reaction, because the oxidation number has decreased. So the N has gained electrons.

NO₃⁻ + 1e⁻ → NO₂

In acidic medium, we have to add water, where there are less oxygens to ballance the amount. We have 2 O in left side, and 3 O in right side, so we have to add 1 H₂O on left side.

NO₃⁻ + 1e⁻ → NO₂ + H₂O

Now that oxygens are ballanced, we have to ballance the hydrogens by adding protons in the opposite side

2H⁺ + NO₃⁻ + 1e⁻ → NO₂ + H₂O
