What is the dissolution formula for a compound?
The dissolution formula for a compound is a way to represent how the compound breaks apart into its individual ions or molecules when it is dissolved in a solvent. It is typically written as a chemical equation showing the reactants (the compound being dissolved) and the products (the ions or molecules it breaks into).
Why do scientists use resonance structures to represent some molecules?
Scientists use resonance structures to represent molecules because they provide a more accurate description of the electron distribution within the molecule. By showing different possible locations of electrons in a molecule, resonance structures help explain the stability and reactivity of the molecule.
How many molecules of methane are in 0.500 mol of CH4 gas?
The formula for methane is CH4, showing that each molecule contains exactly 5 atoms. Therefore, the number of atoms in 0.650 ml is 5 X 0.650 X Avogadro's Number, or about 1.96 X 1024 atoms, to the justified number of significant digits.
What happens to the potential energy of the molecules in a reaction?
The potential energy of the molecules change during a reaction.
Which of the schematic drawings best describes a solution of li2SO4 in water water molecules not shown for simplicity?
Diagram C, or the diagram that has more Li ions (circles with the + sign in them) than the SO4 molecules (circles with the 2- sign in them).
What does water bond with when its showing cohesion?
Water molecules are associated by hydrogen bods.
In A Separate Peace Why does leperelli enlist?
because he saw a film at Devon showing military skiing
When was picture frames invented?
They evolved over thousands of years but really started showing up as a separate item in the 1700's.
Which diagram best represents molecules of matter in solid phase?
A diagram showing molecules closely packed together in a regular and organized pattern represents molecules in the solid phase. The molecules in a solid are held together by strong bonds and have very little movement.
What is the difference between adding a subscript 2 to the end of the formula for co to give co2 and adding a coefficient in front of the formula to give 2co?
when you put is as a subscript such as CO2 you are showing that there are two atoms of oxygen in the molecule of carbon dioxide. When you put the two at the beginning of the phrase such as 2CO you are showing that you have two separated molecules of carbon linked to oxygen.
What process is energy stored in organic molecules?
The Lewis structure of a carbon atom, showing its four valence electrons.
What is a glucose standard curve and why did you need to obtain one for experiment?
A glucose standard curve is a method of monitoring blood glucose over a period to identify patterns and peaks in glucose levels. Understanding regular glucose levels can help isolate medical conditions and promote the success of treatment plans. Glucose standard curves track the changes in glucose levels over time and map any spikes or lows in readings
Why starch with water shows positive result for starch test and negative result for maltose test?
Starch reacts positively in a starch test due to the presence of amylose and amylopectin, which form a blue-black complex with iodine. This complex indicates the presence of polysaccharides. In contrast, maltose is a disaccharide that does not contain the long chains of glucose units found in starch, so it does not produce a reaction with iodine, resulting in a negative result for the starch test. Conversely, maltose can be tested with Benedict's solution to confirm its presence, showing a positive result for reducing sugars.
How do you get your PIP Sony to show 2 separate screens at 1 time?
I can pull up the small screen but it only shows whatever the large screen is showing
Which graph or chart represents data as part of a whole?
A pie graph represent data as a part of a whole, showing the separate portions of the data in accordance to the whole.
How was Amerigo Vespucci discovery honored?
Amerigo Vespucci published a map showing the Americas as a separate set of continents, not as part of Asia. America was named in his honor.
How do you test for glucose?
1. Place a small amount of glucose with some Benedict's solution in a test tube 2. Heat this by putting the test tube in a beaker of boiling water. 3. Once you've done this, the solution will turn from clear blue to cloudy green before changing again in colour to yellow and then lastly a precipate red copper (1) oxide will be deposited.
