Example of Anchoring Bias

Answers

Answer:

Here is an example of anchoring Bias

If I were to ask you where you think Apple’s stock will be in three months, how would you approach it? Many people would first say, “Okay, where’s the stock today?” Then, based on where the stock is today, they will make an assumption about where it’s going to be in three months. That’s a form of anchoring bias. We’re starting with a price today, and we’re building our sense of value based on that anchor.

Anchoring bias occurs when people rely too much on pre-existing information or the first information they find when making decisions. For example, if you first see a T-shirt that costs $1,200 – then see a second one that costs $100 – you're prone to see the second shirt as cheap.

Anchoring or focalism is a term used in psychology to describe the common human tendency to rely too heavily, or "anchor," on one trait or piece of information when making decisions.

Which characteristic of a substance is considered a chemical property?

its boiling point
its reactivity
its density
its conductivity

Answers

A chemical change is one that can ONLY be observed when a substance undergoes a chemical reaction. Because reactivity is the only characteristic here that concerns chemical reactions, that is the correct answer.
reactivity is correct because it is the only experiment that ends in a chemical change.

Explain what happens if you change the number of protons in an element?

Plzzz helpppp!!!​

Answers

Answer:

When you change the number of protons in an atom, you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive. If you change the number of electrons in an atom, you will get an ion of the element.

A chemist burns 0.8 g of iron in oxygen.
The iron reacts to form 1.1 g of iron oxide.
Calculate the mass of oxygen that reacted with the iron.

Answers

Answer:

0.3g

Explanation:

1.1 - 0.8 = 0.3

Hope this helps

The mass of oxygen that reacted with the iron is 0.3g

The chemist burns 0.8g of iron in oxygen

the iron reacts to form 1.1g of iron oxide

Therefore the mass of oxygen can be calculated by subtracting the mass of iron in oxygen from the mass of iron

= 1.1 - 0.8

= 0.3g

Hence the mass of oxygen that reacted with the iron is 0.3g

How many moles do you have if you have 8.03 x 1023 atoms of oxygen?

Answers

Answer:

The answer is 1.33 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{8.03 \times {10}^{23} }{6.02 \times {10}^{23} } \\ = 1.33388704...[/tex]

We have the final answer as

1.33 moles

calculate the oxidation number of s in S2O8^2-​

Answers

Given problem:

    S₂O₈²⁻

Find the oxidation number of S;

Oxidation number presents the extent of oxidation of each atom of elements a molecular formular or formula unit or an ionic radical.

  For radicals:

          "the algebraic sum of all the oxidation numbers of all atoms in an ion containing more than one kind of atom is equal to the charge on the ion  "

 S₂O₈²⁻;   oxidation number of O is usually -2

             2(S) + 8(-2) = -2

               2S - 16  = -2

               2S = -2 + 16

                2S  = 14

                   S  = +7

The oxidation state of S in the radical is +7
