<h2>The Best-used Solvent is Hexane.</h2>

Explanation:

In the given solvents -

Hexanes, Toulene, and dichloromethane have lesser eluting power.
Diethyl ether and Ethyl acetate have medium eluting power.
Methanol, water, and acetic acid have very little eluting power.
Greater is the eluting power of the solvent lesser is the amount to be added.
For solvents like Diethyl ether and Ethyl acetate have to be added in the percentage of 1% - 50% in addition to the solvent of higher eluting power.
Hexanes and Toulene are often used in TLC (Thin Layer Chromatography ) as a Base.
The reason behind this is they are non-polar compounds.
The best-used solvent is Hexane.

Determine the amount of heat energy in joules required to raise the temperature of 7.40g of water from 29.0OC to 46.0 OC.

valina [46]

Answer: The amount of heat energy in joules required to raise the temperature is 526 Joules

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

$Q=m\times c\times \Delta T$

Q = Heat absorbed = ?

m= mass of substance = 7.40 g

c = specific heat capacity = $4.184J/g^0C$

Initial temperature of the water = $T_i$ = 29.0°C

Final temperature of the water = $T_f$ = 46.0°C

Change in temperature , $\Delta T=T_f-T_i=(46.0-29.0)^0C=17.0^0C$

Putting in the values, we get:

$Q=7.40g\times 4.184J/g^0C\times 17.0^0C$

$Q=526J$

The amount of heat energy in joules required to raise the temperature is 526 Joules

what property of the noble gases most likely prevented the gases from being readily/easily discovered?

Vlad [161]

These gases very rarely react, with others and also noble gases are odourless and colourless.

Explanation:

Noble gases will not react with anything so that is the reason why they are known as an inert gas.

Noble gases are present in group 18 on the periodic table and following the rule of the octet which is they completed their orbital by s2p6 which is the highest energy level.

Most elements are discovering through their reactivity with the other elements, commonly with oxygen. In the case of a noble gas, it is difficult for a scientist to work with the gases which have very less or no chemical property in terms of their reactivity.

Use a sheet of paper to answer the following question. Take a picture of your answers and attach to this assignment. Predict the

romanna [79]

Answer:1-methoxy-2,4-dinitrobenzene

Explanation:

The nitro groups are strongly electron withdrawing and promote nucleophilic substitution reactions where one of the original substituents is removed and replaced by a strong nucleophile such as the methoxy group. The mechanism of the reaction is attached below. The electron withdrawing nitrogroup assists the formation of the intermediate in the reaction as shown.

A mouse runs across a 4.56 m kitchen floor in 3.42 seconds . What is the velocity of the mouse

Lerok [7]

Velocity is the change in position divided by the time . In your problem, it should be expressed in meters per second. To solve, you must divide the distance, 4.56 meters, by the time it takes to travel that distance, which is 3.42 seconds -----> 4.56/3.42 = 1.333 meters per second is the velocity of the mouse
