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.

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.

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

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.

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.

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is
