Example of Anchoring Bias
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.

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.
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

Hydrochloric acid is a strong acid and carbonic acid is a weak acid. Yet 1 L of 1 M HCl solution will neutralize 1 mole of NaOH and 1 M of carbonic acid will neutralize 2 moles of NaOH. Explain.
Answer:
A mixture of a weak acid and its conjugate base is called a buffer solution, or a buffer. Buffer solutions resist a change in pH when small amounts of a strong acid or a strong base are added.

What kinds of organisms have "naked" DNA?
Answer:
The DNA in prokaryotes is naked DNA.
Explanation:
Prokaryotes have cell walls which are a network of fibres that provides the cell with strength and rigidity. This network in the cell wall allows the cell to be freely permeable. These differ from eukaryotes which have a nucleus containing genetic information (DNA).

Answer:
Exothermic
Explanation:
calculate the oxidation number of s in S2O8^2-
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

Explain what happens if you change the number of protons in an element?
Plzzz helpppp!!!
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.
in your own words describe the process of a physical change
Answer:
A physical change is when the form of an object changes, but the substance stays the same.

How many moles do you have if you have 8.03 x 1023 atoms of oxygen?
Answer:
The answer is 1.33 molesExplanation:
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
