Answer:
(I hope this helps enough)
Explanation:
A wide spectrum of inorganic analytes are analyzed using redox titrimetry. By testing an unknown analyte against a standardized titrant, a redox titration (also known as an oxidation-reduction titration) can correctly calculate its concentration. It is used to determine the presence of organic analytes.
Answer: C₇H₁₄ + 7O₂ → 7CO + 7H₂O
Explanation:
- For any equation to be balanced the number of (C, H, and O) atoms in the reactants side should be the same in the products side.
- The first choice is wrong because it is unbalanced equation that the reactants side has 22 O atoms and in the products side there is 14 O atoms.
- The second choice is wrong because the incomplete combustion of heptene results CO and/or CO₂ and H₂O.
- The third choice is the right answer that it has 7 atoms of C, 14 atoms of H, and 14 atoms of O in both reactants and products sides.
- The fourth choice is wrong because the combustion of heptene occurs in O₂ not in O.
Answer:
Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size. Gas particles are in constant rapid motion in random directions. Collisions between gas particles and between particles and the container walls are elastic collisions.
According to Versatile Carbon - ChemEd DL Carbon is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.
The Mass of ice is 69.12g.
What is mass?
It is a dimensionless quantity that expresses a particle or object's mass. The accepted unit of mass under the International System (SI) is the kilogram.
What is temperature?
Temperature is a measure of the average kinetic energy of the particles inside an object. The temperature increases cause these particles to move more quickly. It is possible to measure temperature using a thermometer or a calorimeter.
first calculate the amount of heat as follows;
q= mass of water C= (0°C-55°C)
=100.0g (4.186J/g°c) (-55°C)
=-23023J
Heat lost by water is gained by ice,
-q=m*ΔH
-23023J= m*333J/g
= 69.12g
Therefore, Mass of ice is 69.12g.
