WHY IS BORAX CONSIDERED A PRIMARY STANDARD?
Borax is considered a primary standard because it is a solid compound with a high degree of purity, a high molecular weight, and stable chemical properties. These characteristics make it suitable for accurately measuring the concentration of acids or bases in a titration procedure.
What is the primary factor that determines which of these substances is most responsible for chemical reactions?
The primary factor that determines which substance is most responsible for chemical reactions is the reactivity of the substances involved.
What is the primary driving force for osmosis?
Osmosis is the movement of water through a semi-permeable membrane. When there are different concentrations on either side, the water moves from the side that has the least concentration of solute to the side with the higher concentration of solute. So a different solute concentration drives osmosis.
Difference between primary standard solution and a secondary standard solution in acid-base titration?
primary standard solution is prepared by direct measurements of the mass of solute and the volume of solution.whereas, a secondary standard solution is a solution whose concentration can't be determined directly from weight of solute and volume of solution, the concentration must be determined by analysis of the solution itself.
What chemicals in alcohol make you drunk?
Alcohol, or ethanol, is the primary chemical in alcoholic beverages that makes you feel drunk. When consumed, ethanol affects the central nervous system, leading to alterations in brain function and behavior. The concentration of alcohol in the blood, known as blood alcohol concentration (BAC), determines the extent of intoxication.
The primary chemical stimulus used to control breathing is changes in the concentration of?
The primary chemical stimulus used to control breathing is changes in the concentration of carbon dioxide in the blood. When carbon dioxide levels increase, it triggers an increase in breathing rate to remove excess carbon dioxide and restore balance.
Is oxygen the primary stimulus for breathing?
no
Primary active transport involves a conformational change in the carrier protein The most immediate stimulus for this is?
The most immediate stimulus for the conformational change in the carrier protein in primary active transport is the binding of ATP or another source of chemical energy. This energy is used to pump molecules against their concentration gradient.
What is meant by chemotropism?
Tropism is defined as the movement, generally by a plant, due to outside stimuli; direction of sunlight being a primary stimulus. Chemotropism is defined as oriented growth or movement in response to a chemical stimulus.
What is the primary concentration of lymph nodes?
the primary concentration is in the cervical spine
What is the primary stimulus for the release of cortisol and corticosterone?
ACTH
What is the primary stimulus to breathe?
carbon dioxide (CO2)
What is the primary gas that humans exhale when breathing?
The primary gas that humans exhale when breathing is carbon dioxide.
What is the breathing sound of a child having a primary koch's infection?
You can not identify the primary complex of a child from the breathing sound.
The primary stimulus to social and economic reforms during the Progressive Era came from?
Authours and social activists provided the stimulus.
A stimulus that acquires reinforcing power by association with a primary reinforcer is called?
A conditioned reinforcer. It is a stimulus that gains reinforcing properties through association with a primary reinforcer, making it effective in influencing behavior.
What is the respiratory system of a squid primary purpose?
breathing. -.-
