  1. Jul 22, 2021 · Another way to represent the H + concentration is the pH, which is the negative logarithm of the H + molarity. The following equation shows this mathematical relationship as well as the way to calculate the H + molarity given the pH: pH = –log [H + ]; [H +] = 10 –pH. pH = 7 is neutral. pH less than 7 is acidic.

    Pavlov’s discovery of classical conditioning arose out of his observations of his dogs’ salivation responses. While dogs naturally salivate when food touches their tongues, Pavlov noticed that his dogs' salivation extended beyond that innate response. They salivated when they saw him approach with food or even just heard his footsteps. In other wor...

    Classical conditioning requires placing a neutral stimulus immediately before a stimulus that automatically occurs, which eventually leads to a learned response to the formerly neutral stimulus. In Pavlov’s experiments, he presented food to a dog while shining a light in a dark room or ringing a bell. The dog automatically salivated when the food w...

    Each of the stimuli and responses in classical conditioning is referred to by specific terms that can be illustrated with reference to Pavlov’s experiments. 1. The presentation of food to the dog is referred to as the unconditioned stimulus (UCS) because the dog’s response to the food occurs naturally. 2. The light or bell is the conditioned stimul...

    The process of classical conditioning occurs in three basic stages: Before Conditioning At this stage, the UCS and CS have no relationship. The UCS comes up in the environment and naturally elicits a UCR. The UCR wasn’t taught or learned, it’s a completely innate reaction. For example, the first time a person takes a ride on a boat (UCS) they may b...

    There are several additional principles in classical conditioning that further detail how the process works. These principles include the following: Extinction As its name suggests, extinction happens when a conditioned stimulus is no longer associated with an unconditioned stimulus leading to a decrease or complete disappearance of the conditioned...

    Examples of classical conditioning can be observed in the real world. One instance is various forms of drug addiction. If a drug is repeatedly taken in specific circumstances (say, a specific location), the user may become used to the substance in that context and require more of it to get the same effect, called tolerance. However, if the individu...

    While there are numerous real-world applications for classical conditioning, the concept has been criticized for several reasons. First, classical conditioning has been accused of being deterministic because it ignores the role of free will in people's behavioral responses. Classical conditioning anticipates an individual will respond to a conditio...

  3. In chemistry, conditioning is a process in which chemical reaction factors are stabilized or enhanced. Examples include increasing the quality of a material by using another material (a conditioner) or improving the ability of solids to capture and physically or chemically treat water. There are three main conditioning systems: heat, inorganic ...

    • What does chemistry mean? As an introduction to chemistry, it is the branch of science that studies matter and change. First, chemistry deals with the study of the composition and the properties of matter (which is basically any macroscopic substance that we can observe).
    • When was chemistry “discovered”? Very simple chemical processes were performed even during ancient history, at 1000 BC, much before any basic chemistry concepts or laws were actually established.
    • Why is chemistry important? Everything is chemistry. Everything that you can observe macroscopically is made of chemicals. You are made of chemicals, your food is chemicals, you breathe chemicals, we live out of and thanks to chemicals, everything you see under the sun is a mixture of chemicals.
    • Why is chemistry called central science? A all sciences are glued together by basic chemistry concepts, thats why it is called the central science. Without chemistry, physical sciences (which include chemistry itself), would find a gap and not be bound to life sciences (such as biology) and applied sciences (such as engineering).
  4. Conditioning is a form of learning in which either (1) a given stimulus (or signal) becomes increasingly effective in evoking a response or (2) a response occurs with increasing regularity in a well-specified and stable environment. The type of reinforcement used will determine the outcome. When two stimuli are presented in an appropriate time ...

  5. Feb 1, 2024 · Classical conditioning is a learning process in which a neutral stimulus becomes associated with a reflex-eliciting unconditioned stimulus, such that the neutral stimulus eventually elicits the same innate reflex response that the unconditioned stimulus does. For example, pairing a bell sound (neutral stimulus) with the presentation of food (unconditioned stimulus) can cause an organism to ...

  6. Jan 10, 2021 · Synthesis Reaction Definition. A synthesis reaction is a chemical reaction that combines two or more simple elements or compounds to form a more complex product. A + B → AB. This type of reaction is also called a direct combination reaction or simply a combination reaction. It’s the type of reaction that forms compounds from their elements.
