Answer:I apologize, as an AI language model, I do not have the capability to draw chemical structures or images. However, I can provide a description of the starting material and product, as well as their charges.
The starting material for the preparation of lithium diisopropylamide is diisopropylamine, which has the chemical formula (CH3)2CHNH(CH3)2. When diisopropylamine is treated with n-butyllithium (n-BuLi), a strong base, it forms lithium diisopropylamide, which has the chemical formula (CH3)2CHNLi. Lithium diisopropylamide is a strong, nonnucleophilic base that is often used in organic synthesis as a deprotonating agent. The lithium cation in lithium diisopropylamide has a charge of +1, while the nitrogen atom has a charge of -1 due to the transfer of an electron pair to the lithium ion.

What is soil horizon?Soil horizon contains different layers of soil which are classified based on the composition of the soil and the presence of rocks within the soil. The primary level of the soil is rich in humus. The decomposed of matter of plants and animals are called humus. On which the plants are growing.
The secondary level of soil horizon or the subsoil level contains some small rocks also onto which the roots of plants does not adhere so much. The third level of soil horizon contains bigger rocks with small gaps between them.
The last layer of the soil horizon is called bedrock layer containing bigger rocks with no significant gaps between them It is called the bedrock layer.

Explain why it is often necessary to start a campfire with many pieces of kindling (small pieces of wood) rather than with a few large logs
Answer:
It is often necessary to start campfire with many pieces of kindling rather than large logs because it is easier to ignite smaller pieces than larger pieces. Imagine wanting to light up a pile of clothes and a small piece of a shirt. Which ignites faster? The piece of a shirt, because it is smaller and more likely to burn very quickly. Additionally, people criss-cross these tiny pieces of wood to enable more surface area and to allow more oxygen to pass through. As you know, oxygen is necessary for a flame to ignite.

substances can be categorised in two ways: as an element, mixture or compound ora as a solid, liquid or gas. which
of these methods Is of most use ti chemist?
Answer:
Most substances on earth are compounds and most interesting chemistry is done with compounds. Most interesting chemistry is done with mixtures of compounds although they often start with pure compounds and then do reactions as mixtures. Most chemistry is carried out in liquid solutions made up of compounds that are solids, liquids, or gases in their pure form.
Explanation:
Here, we are required to determine which of these methods of classifying substances is most important to chemists.
The most useful classification of compounds to chemists is as Elements, Compounds or MixturesFirst classification of substances involves categorising them as pure substances (elements and compounds) or mixtures.
The second classification of substances is categorisation with respect to their state of matter. In essence, we can have solid, liquid or gas.
However, the most useful classification of compounds to chemists is as Elements, Compounds or Mixtures.This is so because, the type of matter present in Elements are distinct for each element, same as for Compounds and Mixtures formed from a combination of pure substances.
Chemists focus on the diverse properties of substances, as such classification as elements, compounds and mixtures provides a wide basis for the qualitative and quantitative analysis of the properties of substances.Classification of substances as solid, liquid or gas leaves a narrow avenue for the study of substances as the substance still contains the same type of matter, only this time in different states.Read more:

If the molecular mass of a substance is 7.304 • 10²³ g, find its molar mass.
Answer:
1.213 g/mol
Explanation:
We are given that the molecular mass is 7.304 × 10²³ g.
From avogadro's number, we know that;
1 mole of a substance = 6.022 × 10²³ molecules
Thus;
Molar mass = molecular mass/avogadro's number = (7.304 × 10²³)/(6.022 × 10²³) = 1.213 g/mol
Solid potassium chlorate breaks into potassium chloride and oxygen gas when heated up to high temperature. This is an example of a/an _______ reaction.
Answer:
es correcto bro claro eres un crak
Answer:
Decomposition Reaction
Explanation:
You can determine the type of reaction by writing out a balanced equation.
Solid Potassium Chlorate: KClO3
Potassium Chloride: KCl
Oxygen Gas: O2
Balanced Equation: 2KClO3 -> 2KCl + 3O2
By definition, a decomposition reaction is when a single substance decomposes into two more simpler substances. AB -> A + B
Because the solid potassium chlorate is breaking into two substances, potassium chloride and oxygen gas, it is a decomposition reaction.

Which phrase describes runoff?
1.underground water that flows into lakes
2.river water that empties into an ocean
3.water from streams that flows into larger rivers
4.water from rain and snow that travels to streams
Please help!
Explanation:
water from rain and snow that travels to streams
Please help!
Water from a rain and snow that travels to streams are examples of run off. These natural processes are part of water cycle and balance the water content in the atmosphere and hydrosphere.
What is water cycle ?Water cycle is a geological phenomenon to balance the water content in the atmosphere, hydrosphere and in the biosphere. The water bodies evaporate by the heat radiated by sun.
The air moisture can be restored to the land through the cooling of the vapor and pour as rain. This best illustrates the interaction between atmosphere and hydrosphere.
Rain, snow, sleet, or hail that reaches a surface stream without ever going below the soil's surface is referred to as surface runoff. It differs from direct runoff, which is runoff that directly reaches surface streams following rainfall or snowmelt. Hence option 4 is correct.
