What mountain is oceanic oceanic?
An ocean mountain is a mountain that is completely underwater. If measured from sea level, it would have a negative height.
What is an ion that is composed of only a single atom?
could be monatomic but many ions are comprised of multiple atoms - for example when sulfuric acid dissociates, one of the ions it yields is SO4-- (having trouble getting a superscript but the ion has a double negative charge)
What charge would a sulfur ion have?
its has 2 electron, therefore 2-
Does fluorine form a positive or negative ion?
Negative (Fl-) All the halogens become negative ions.
What is negative 20 degrees Fahrenheit in Celsius?
°C = (°F − 32) × 5⁄9 °C = (-20 − 32) × 5⁄9 °C = -53 × 5⁄9 °C = -29.4 Therefore -20°F is equal to -29.4°C
How calculate pH for a solution?
HCl is a strong acid and dissociates completely. Therefore it can be found using the equation: ph= -log [H+]
A substance that completely dissociates into its ions in solution?
A strong electrolyte is a substance that dissociates completely into positive and negative ions in its solution. Examples of strong electrolytes that are acids are hydrochloric and nitric acids.
When Is an acid considered a strong acid?
A strong acid completely dissociates into its H+ ion and its negative ion in a 1.0M solution. For example, sulfuric acid, H2SO4, completely dissociates into its hydrogen ions, H+, and its sulfate ions, SO42-. The strong acids are as follows: hydrochloric acid, HCl, nitric acid, HNO3, sulfuric acid, H2SO4, hydrobromic acid, HBr, hydroiodic acid, HI, and perchloric acid, HClO4. (About.com chemistry)
When a strong acid dissolves in water how many molecules break apart?
All of them. The definition of a strong acid is a molecule that completely dissociates into hydrogen ions and a negatively charged ion in water. In contrast, a weak acid is a molecule that partially dissociates into hydrogen ions and a negative charge ion in water - you can find both the intact acid form (HA) and the ion forms (H+ and A-) in the water.
Are ions negatively charged?
You can have positive ions and negative ions. For example, take saltwater which dissociates into: Na+ & Cl- Typically the number positive charges and negative charges must balance.
The Ability of writers to completely identify with their characters is?
The ability of writers to completely identify with their character is known as negative capability.
What acid is not a strong acid?
The strength of an acid does not depend on how corrosive it is but by the degree to which it dissociates in water. A strong acid completely dissociates into ions, producing hydrogen (H+ ions) and negative ions that depends on the particular acid (HCl --> H+ + CL-, HNO3 -- H+ + NO3-). A weak acid only partially dissociates. The strong acids are: Hydrochloric acid (HCl) Hydrobromic acid (HBr) Hydroiodic acid (HI) Nitric acid (HNO3) Sulfuric acid (H2SO4) Perchloric acid (HClO4) Some lists also include periodic acid (HIO4) and chloric acid (HClO3) as strong acids. All other acids are assumed to be weak.
Why negative times positive equals negative?
when you multiply something you increase the value. therefore, when you multiply a negative by a positive, you'll get a negative.
What is critisism?
Criticism is having a comment for something and delivering it, whether in a positive or completely negative way. Criticism is having a comment for something and delivering it, whether in a positive or completely negative way.
When you multiply a positive integer by a negative integer is the result positive or negative?
Example 5 × −6 = −30 therefore it is negative.
Why the product of two negative numbers is positive.?
Multiplying something by a negative number makes it change signs. A positive number multiplied by a negative is negative therefore a negative * a negative is positive.
Is nigrosine repelled by negative charges in bacteria?
Yes. It is a negative stain and so therefore repels and is repelled by other negative charges.
