Komok [63]

<span>Balanced chemial equation:

2NaI(aq)+Hg2(NO3)2(aq) →Hg2 I2 (s) + 2 NaNO3 (aq)

You can see it better if I use latex:

$2NaI(aq)+Hg_2(NO_3)_2(aq) =Hg_2 I_2 (s) + 2 NaNO_3 (aq)$

As per the phases this is the interpretation:

The symbols (aq) stands for aquous meaning that the compound is dissolved in water.

The symbol (s) stands for solid, meaning tha the compound precipitate and is not dissolved in water.</span><span>

kompoz [17]

Answer:

The fatty acids and glycerol contributes to soap’s slippery texture.

Explanation:

What we need to know is that every oil has a specific index for strength, cleaning, etc.
All of them are determined by the amount of certain fatty acid in the oil.

When we make soap, what we need to know is that oil has a special role to play in that soap.
So for example some of those oils are used to make bubble soap or creamy soap.
On the other side, there are some oils which are giving strength to soap.

With the kinetic energy of a sample increases the____ will also increase

klemol [59]

Answer:

Its Temperature.

Explanation:

Kinetic energy is the energy possessed by a body while in motion. Potential energy on the other hand is the energy possessed by a body based on its position.
Kinetic energy of a body is determined by the equation; K.E = 3RT/2;
From the equation, kinetic energy is directly proportional to the temperature of the system and therefore an increase in the kinetic energy of a sample causes an increase in temperature of the system.
