Answer:

Explanation:For example, you are in a bus and it goes with the velocity of 50 m/s to the east, then a truck passes you with a velocity of 60m/s to the east. ... Velocity of the moving objects with respect to other moving or stationary object is called “relative velocity” and this motion is called “relative motion”

How would you describe the solid-state in terms of motion (ability to move in the space and speed) and distance between molecule

horrorfan [7]

In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.

According to the kinetic theory of matter, the molecules that compose matter are in constant random motion. The nature of this motion varies in the three states of matter which are;

Solid
Liquid and
Gas

In the solid state, the molecules do not translate, they only vibrate and rotate about their mean positions. In the liquids state, the molecules translate but they still have restricted degrees of freedom due to intermolecular interactions. In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.

A sample of unknown hydrate, AC-XH20, has a mass of 1.000 g before heating and a

KIM [24]

Answer:

The water of crystallization for the formula of the unknown hydrate is 2.

Explanation:

Mass of an unknown hydrate = 1.000 g

Molar mass of hydrate = 195.5 g/mol

MOles of unknown hydrate = $\frac{1.000 g}{195.5 g/mol}=0.00512 mol$

Mass of hydrate after heating = 0.781 g

Mass of water lost due to heating = x

$1.000 g = 0.781 g + x\\x = 1.000 g - 0.781 g = 0.219 g$

Moles of water lost = $\frac{0.219 g}{18.01528 g/mol}=0.0122 mol$

$AC.xH_2O+Heat\rightarrow AC+xH_2O$

1 Mole of hydrate has x moles of water and 0.00512 moles of hydrate has 0.0122 moles of water then we can write:

$\frac{1 }{x}=\frac{0.00512 }{0.0122 }\\x\approx 2$

The water of crystallization for the formula of the unknown hydrate is 2.

Determine the name for aqueous H2CO3. carbonous acid dihydrogen carbonate carbonic acid hydrocarbonic acid hydrocarbide acid

BabaBlast [244]

The name for aqueous $H_{2} CO_{3}$ is carbonic acid.

So, option C is correct one.

Binary hydrogen compounds with non metals may form H+ (proton) and an anion dissolved in water. The acidic solutions are named as if they were molecular acids , using the usual name for the compound itself , replacing hydrogen with hydro- and suffix -ide with ic. The word acid is then use.

The inorganic acid is an acid drive from one or more inorganic compounds. All inorganic acids form hydrogen ions and the conjugate base ions when dissolved in water.

Example: carbonic acid ( $H_{2} CO_{3}$ )
