Explanation:For these types of question, try to make the structural diagram FIRST,I have attached the files labelling the respective hybridized CARBON ATOM.Here, Red circle denotes sp³ while green circle denotes sp² and blue circle denotes sp hybridized Carbon atom. From the figure you can configure the sp, sp², sp³ RATIO in option A, B and C are as follow:A) 1:2:3B) 3:2:1C) 2:4:0So correct option is A

Molarity The most common unit of solution concentration is molarity (M). The molarity of a solution is defined as the number of moles of solute PER one liter of solution. Note that the unit of volume for molarity is liters, not milliliters or some other unit. Also note that one liter of solution contains both the solute and the solvent. Molarity, therefore, is a ratio between moles of solute and liters of solution. To prepare laboratory solutions, usually a given volume and molarity are required. To determine molarity, the formula weight or molar mass of the solute is needed. The following examples illustrate the calculations for preparing solutions. If starting with a solid, use the following procedure: • Determine the mass in grams of one mole of solute, the molar mass, MMs. • Decide volume of solution required, in liters, V. • Decide molarity of solution required, M. • Calculate grams of solute (gs) required using equation 1. eq. 1. gs = MMs x M x V • Example: Prepare 800 mL of 2 M sodium chloride. (MMNaCl = 58.45 g/mol) gNaCl = 58.45 g/mol x 2 mol/L x 0.8 L gNaCl = 93.52 g NaCl Dissolve 93.52 g of NaCl in about 400 mL of distilled water, then add more water until final volume is 800 mL. If starting with a solution or liquid reagent: • When diluting more concentrated solutions, decide what volume (V2) and molarity (M2) the final solution should be. Volume can be expressed in liters or milliliters. Basic Concepts of Preparing Solutions Many of the reagents used in science are in the form of solutions which need to be PURCHASED or prepared. For many purposes, the exact value of concentration is not critical; in other cases, the concentration of the solution and its method of PREPARATION must be as accurate as possible. The Flinn Laboratory Solution Preparation reference section is designed for both the novice and experienced solution maker. It provides valuable information on the basic concepts of preparing solutions and instructions for preparing most solutions required in the high school science laboratory. Professional quality solutions are possible when high quality and fresh chemicals and solvents are used, and meticulous procedures are followed. Many of the solutions described • Basic concepts of preparing solutions • Over 300 recipes of common laboratory solutions • Solution preparation tips Laboratory Solution Preparation in this section are available ready-made from Flinn Scientific to save valuable laboratory prep time. The section is divided into several parts for your convenience. Basic concepts of preparing solutions Preparation of simple inorganic salt solutions Preparations of acid and base solutions Recipes for Biological, Histological, and CHEMICAL solutions • Determine molarity (M1) of starting, more concentrated solution. • Calculate volume of starting solution (V1) required using equation 2. Note: V1 must be in the same units as V2. eq. 2. M1V1 = M2V2 • Example: Prepare 100 mL of 1.0 M hydrochloric acid from concentrated (12.1 M) hydrochloric acid. M1V1 = M2V2 (12.1 M)(V1) = (1.0 M)(100 mL) V1 = 8.26 mL conc. HCl Add 8.26 mL of concentrated HCl to about 50 mL of distilled water, stir, then add water up to 100 mL. Percent Solutions Mass percent solutions are defined based on the grams of solute per 100 grams of solution. Example: 20 g of sodium chloride in 100 g of solution is a 20% by mass solution. Volume percent solutions are defined as milliliters of solute per 100 mL of solution. Example: 10 mL of ethyl alcohol plus 90 mL of H2O (making approx. 100 mL of solution) is a 10% by volume solution. Mass-volume percent solutions are also very common. These solutions are indicated by w/v% and are defined as the grams of solute per 100 milliliters of solution. Example: 1 g of phenolphthalein in 100 mL of 95% ethyl alcohol is a 1 w/v% solution. © 2011 Flinn Scientific, Inc. All Rights Reserved.

Key Takeaways. MATTER has MASS and occupies volume. Heat, light, and other forms of electromagnetic energy do not have measurable mass and can't be CONTAINED in a volume. Matter can be converted into energy, and vice versaANSWERED BY-∆∆∆{PRINCE ROY~} (-_-)

Reaction rate, in chemistry, the SPEED at which a chemical reaction proceeds. It is often EXPRESSED in terms of EITHER the concentration (AMOUNT per unit volume) of a product that is formed in a unit of time or the concentration of a REACTANT that is consumed in a unit of time.FOLLOW

is the CENTRAL atom in water molecules. ... Therefore, two hydrogen atoms form 1 SIGMA BOND (each) with the central OXYGEN atom. The total number of electron pairs in the valence shell of the oxygen atom is 2. Therefore, according to the VSEPR theory, water molecules have a BENT shape (they are V-shaped).

Schottky defect occurs in those ionic CRYSTALS where difference in size between CATION and anion is small. In Schottky defect, both cation and anion leave the solid CRYSTAL. In Frenkel defect, only the SMALLER ION (cation) leaves its original lattice site; whereas, the anion remains in original lattice sites.Explanation:Hope this helped you.

what QUESTIONS you WANT ANSWER then I will GIVE you a answer

IT'S NO B THAT IS THE CORRECT ANSWER

An ATOM is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is USUALLY surrounded by ONE or more electrons. Each electron is negatively charged. The nucleus is POSITIVELY charged, and contains one or more relatively heavy particles known as protons and neutrons.
