2017年12月14日 · The empirical formula is the simplest WHOLE number defining constituent atoms in a species.... The molecular formula is always a whole number multiple of the empirical formula.... Here we gots C_5H_10O_5, whatever this is, some sugar.... The "empirical formula"-=CH_2O....and clearly the molecular formula is a whole number multiple....C_5H_10O_5 …

What is the vapor pressure of a solution comprised of 100.0 g of water (molar mass = 18.02 g/mol) if 10.0 g of solute A (molar mass = 32.05 g/mol) and 10.0 g of solute B (molar mass = 31.05 g/mol) are dissolved in it at 1 atm and 20 C assuming the solutes

What is C5H10O5? Molecular and Structural Formulas: In chemistry, a molecular formula gives the exact number of each type of atom within a molecule, however, it does not show how the atoms are arranged.

A sample of sugar D-ribose C5H10O5 of mass 0.727 g was placed in a bomb calorimeter at 298 K and then ignited in the presence of oxygen. The temperature rose by 0.910 K. In a separate experiment in the same calorimeter, the combustion of 0.825 g of benzoic acid (C7H6O2) for which the internal energy of combustion is -3251 kJ/mol, gave a ...

2015年12月10日 · The empirical formula of C_5H_10 is CH_2 The empirical formula is the simplest whole number ratio that describes constituent atoms in a species. C_5H_10 of course can be reduced to CH_2. The molecular formula is always a multiple of the empirical formula (the multiple might be 1). A very useful parameter with molecular formulae is the "degree of …

Answer to: Burning a 0.548 g C5H10O5 in a calorimeter caused the temperature to rise from 20.00 deg C to 20.54 deg C. The heat capacity of the...

1. Ribose is a 5 carbon sugar that plays an important role in nucleic acids. The chemical formula for ribose is C5H10O5. WHAT is the molecular mass of ribose? 2. An atom with 4 electrons in its outer shell would likely form how many covalent bonds with other atoms?

The major ingredient in ordinary safety matches is potassium chlorate, {eq}KClO_3 {/eq}, a substance that can act as a source of oxygen in combustion reactions.

2016年4月13日 · Here's how you do it. > The van't Hoff factor, i, is the number of particles formed in a solution from one formula unit of solute. Notice that i is a property of the solute. In an ideal solution, i does not depend on the concentration of the solution. For a nonelectrolyte If the solute is a nonelectrolyte (i.e. it does not separate into ions in solution), i = 1 For example, …

C5H10O5(s) + 5 A 2.053-g sample of ethylene glycol, C_2H_6O_2 (62.07 g/mol) was burned in a bomb calorimeter with excess oxygen. The temperature of the calorimeter and the water before combustion was 16.49 C; after combustion, the calorimeter and the water had a tempera
