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.

If you had 4 protons and 5 neutrons you created which element *

Answers

Answer:

Beryllium

Explanation:

No. of protons = 4

No. of electrons = 4 (number of protons and neutrons are the same)

No. of neutrons = 5

You need to look at the number of electrons of the outer shell (group no.) there are and how many shells there are (period no.)

Then look at the period table of elements to find the element

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

Intermolecular force is the force acting between two different molecules. There are various kinds of intermolecular forces and the they differ in their strength.

What are intermolecular forces?

Intermolecular forces are force of attraction or repulsion acting between two different molecules in a compound. The like charges of molecules repels and unlike charges will attracts together.

There are different kinds of intermolecular forces such as hydrogen bonding, Van der Waal's forces, dipole, dipole forces, London dispersion forces etc.

The strength of these forces vary from each other. The intermolecular force of attraction holds tow molecules together in a compound. Hence, option D is correct.

A boy found a solid metal box in his backyard. The box had been buried for so long, it was difficult to determine from what the box was made. The boy measured the box and found its volume (v) to be 17.63 cubic centimeters (cm3) and its mass (m) to be 158 grams (g). The boy knows the formula for density (D) is D = m/v. This table shows the density of several metals. DENSITY OF METALS *

A. copper
B. gold
C. silver
D. tin​

Answers

Answer:

Box is made up of copper, because density is 8.96  g/cm³.

Explanation:

Given data:

Volume of box = 17.63 cm³

Mass of box = 158 g

Which metal box is this = ?

Solution:

First we will calculate the density of box then we will compare it with the density value of given metals.

d = m/v

d = 158 g/ 17.63 cm³

d = 8.96  g/cm³

The calculated density is similar to the given density value of copper thus box is made up of copper.

D. Hydrogen

an element is a pure substance that cannot be broken down

Answer:

[tex]\boxed {\tt D. \ Hydrogen}[/tex]

Explanation:

An element has a uniform composition, cannot be broken down by chemical change, every atom has the same atomic number, and can be found on the Periodic Table.

Water is made of hydrogen and oxygen atoms (H₂O) so it is not an element.

Table salt is made of sodium and chloride atoms (NaCl) so it is not an element.

Iron oxide is made up of iron and oxygen atoms, so it is not an element.

Hydrogen is an element. It can be found on the Periodic Table as element H.

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.

A sample of gas has a volume of 526 mL at 346 mmHg and 35.0°C. Determine the moles of gas.​

Answers

Answer:

The moles of gas is 0.009474 moles.

Explanation:

Given that,

Volume = 526 mL

Pressure = 346 mmHg

Temperature = 35.0°C

We need to calculate the moles of gas

Using formula of ideal gas

[tex]n=\dfrac{PV}{RT}[/tex]

Where, P = pressure

V = volume

R = gas constant

T = temperature

Put the value into the formula

[tex]n=\dfrac{\dfrac{346}{760}\times0.526}{0.08206\times(35+273)}[/tex]

[tex]n=0.009474\ moles[/tex]

Hence, The moles of gas is 0.009474 moles.
