the ocean because of the fact that in an aquarium if its indoors the sun wont hit it at al even if its outdoors the ocean is way to huge and its because of the ocean that we have clouds. Pond, same thing the ocean beats it

The answer is Ocean.
Oceans are larger than ponds and or an aquarium. Hence they possess wider exposed surface with more number of free surface molecules.Greater the number of surface molecules, greater number of molecules may escape from the surface easily..and hence greater will be the rate of evaporation.
The rate of evaporation depends even on the external climatic conditions such as Temperature, Wind, Pressure etc.
Higher the temperature. higher will be the rate of evaporation.

The ionization of pure water forms _____.

Evgesh-ka [11]

Answer: The ionization of pure water forms hydroxide and hydronium ions.

Explanation:

Ionization is a reaction in the pure water in which water breaks down into its constituting ions that hydronium ion and hydroxide ions.

$H_2O+H_2O\rightleftharpoons H_3O^++OH^-$

One molecule of water looses its proton to form hydroxide ion and l=the lost protons get associated with another water molecule to form hydronium ion.

You need to prepare 150 mL of 0.1 M solution of silver chloride. How much silver chloride is required?

Rudiy27

Answer:

amount of silver chloride required is 0.015 moles or 2.1504 g

Explanation:

0.1M AgCL means 0.1mol/dm³ or 0.1mol/L

1L = 1000mL

if 0.1mol of AgCl is contained in 1000mL of solution

then x will be contained in 150mL of solution

cross multiply to find x

x = (0.1*150)/1000

x= 0.015 moles

moles of silver chloride present in 150 mL of solution is 0.15 moles

To convert this to grams, simply multiply this value by the molar mass of silver chloride

molar mass of silver chloride AgCl =107.86 + 35.5

=143.36 g/mol

mass of AgCl = moles *molar mass

=0.015*143.36

=2.1504g

Determine the type of reaction for the following equation: C2H6 + O2à H2O + CO2

valkas [14]

Answer:

The type of reaction for the following equation is combustion equation.

Explanation:

Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.

$\text{hydrocarbon}+O_2\rightarrow CO_2+H_2O$

The reaction given to us:

$C_2H_6 + \frac{7}{2}O_2\rightarrow 3H_2O + 2CO_2$

When 1 mole of ethane reacts with 7/2 moles of oxygen gas it gives 3 moles of water and 2 moles of carbon dioxide gas.

The type of reaction for the following equation is combustion equation.
