What is true of a Lewis base?
A Lewis base donates electron pairs.
How do you arrange substances in increasing order if you know their density and which substance sinks or floats in various liquids?
Those with more density are placed last. Those with more density sink. Think, light things float because they are less dense than the water.
Who are Scientists contribute periodic table?
The first scientist to make a successful arrangement of elements into a periodic table of the elements was Dimitri Mendeleev. He arranged his elements in order of increasing atomic mass. However, there were some problems with that arrangement. Henry Moseley corrected those problems by arranging the elements in order of increasing atomic number. This is the arrangement we use today.
What would speed up a reaction?
increasing the concentration of reactants
The pH of a substance is a measure of its?
The pH of a solution is a measure of the Hydrogen ion concentration ([H+]), which is a measure of acidity, because one definition of an acid is something which forms Hydrogen ions in solution. The lower the pH, the more acidic the solution. Solutions with pH values below 7 are considered acidic, while those above 7 are considered basic (7 itself is neutral). pH is calculated using the following formula, with concentration measured in mol dm-3: pH = -log10([H+] The scale is logarithmic, so a substance of pH 2 is 10 times more acidic than one of pH 3. Although it is technically only a measure of acidity, it is also used to describe the strength of bases by using the fact that water partially dissociates into Hydrogen and Hydroxide ions: H2O <---> H+ and OH- Therefore if a base is added to water, increasing the number of OH- ions, they will remove H+ from the solution, increasing the pH value.

Are lemon and lime juice interchangeable in canning tomatoes?
It can if too much is added. Typically, when I can salsa, the only recipe I use is in my head. I do use lemon juice to help season it, sometimes I use lime juice. I also help to balance those with sugar, salt, and other seasonings.
What are the five major categories of fungal disease?
Fungal diseases are divided into localized and systemic infections, and then are further subdivided. Localized infections include, in order of increasing depth of infection, superficial, cutaneous, and subcutaneous mycoses. Systemic infections are divided into those that may infect anyone, and those that are opportunistic and don't infect healthy people, but infect those who are immunocompromised.
What conclusion can you draw about the acceleration is it constant increasing decresing or zero?
Depending on the situation, acceleration can be any of those.

What are the tanks on the bottom of the P51 Mustang?
Those are external fuel tanks, which can be dropped from the plane in flight when they run out of fuel, increasing the aircraft's range. They are also usually dropped when entering a dogfight, in order to reduce weight and make the aircraft more aerodynamic.
