after eating an apple and levaing it on top of the table. what will happend to the color of the inner part of the apple? what makes the color of the apple change​

Answers

Answer 1

Answer:

Answer Below

Explanation:

When you leave an apple on a table outside it will turn brown. This happens because when you cut an apple, you are exposing it's insides to the oxygen in the air. This causes the PPO (polyphenol oxidase) enzyme in the apple's flesh to oxidize the polyphenols, turning them into some other brown colored products. Hence, the color change.

Answer 2

Answer:

brown i can't explain because its a matter of the atoms in the apple mixing with the air and apple is made with nitrogen

A sample contain 33.42g of metal pellets are poured on to a graduated cylinder initially containing 12.7ml of water, causing the water level to rise to 21.6ml. Calculate the density of the metal

Answers

Answer:

3. 76 g/ml^3

Explanation:

We are given the mass of the metal pellets which is 33.4 grams. To calculate the density of the metal, we need to divide the mass by the volume. The volume of the metal is not directly given so we need to find it ourselves. The water was initially 12.7 ml and then it rose to 21.6 ml after placing the metal pellets. This indicate that the volume of the metal pellets is 8.9 ml.

[tex]21.6 - 12.7 = 8.9[/tex]

We can now use the density formula.

[tex]p = \frac{m}{v} [/tex]

[tex]p = \frac{33.42}{8.9} [/tex]

[tex]p = 3.76[/tex]

The density of the metal is equal to 3.76 g/ml.

What is the density?

The density of an object can be defined as the mass per unit volume. The average density is equal to the total mass of the object divided by the total volume of the object.

The mathematical formula for the density of the material is expressed as follows:

Density = Mass/Volume

The S.I. unit of the density is Kg/m³ and is an intrinsic property as it is independent of the size. If the size increases, the mass increases as well but the density of the material remains constant.

Given the mass of the metal, m = 33.42 g

Volume of the metal = Volume of water level with metal - volume of water

V = 21.6 -12.7 = 8.9 ml

The density of metal = 33.42/8.9 = 3.76 g/ml

Therefore, the density of the metal is 3.76 g/ml

Enter the symbol of the element which would have 36 electrons and -3 charge.

Answers

Answer:

Arsenic if I understood correctly

Explanation:

Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ions or polyatomic atoms. Therefore, the element with atomic number 33 and -3 charge is Arsenic.

What is Ions?

Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.

Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state. The element with atomic number 33 and -3 charge is Arsenic.

Therefore, the element with atomic number 33 and -3 charge is Arsenic.

An object has 15 grams of atoms and displaces 2.5 mL of water when dropped into a cylinder. What is the objects density... HELP IM IN CLASS RN AND I NEED ANSWERS ASAP, grades are due in couple hours

Answers

Answer:

6g/mL

Explanation:

The density, which is the mass per unit volume of an object, can be calculated using the formula;

D= m/v

Where; D = density (g/mL)

M = mass of substance (g)

V = volume (mL)

In this question, the object's mass = 15g, volume of water= 2.5 mL, d =?

Therefore,

Density = 15/2.5

Density = 6 g/mL

The object's density is 6g/mL

The historical order of atomic models from the earliest to the most recent is as: Hard sphere model, electron shell model, and wave mechanical model. Therefore, option (A) is correct.

What is the atomic model?

The atomic model can be described as the model used to describe the structure and composition of the atom. The atom as a primary component of matter has been under extensive study to understand the universe.

In the classical model of an atom, the atom is made of smaller particles with an electrical charge called electrons, protons, and neutrons. To understand the atomic models, it is important to understand how these particles make up the atom.

There are five principal atomic models that have been proposed over time,  which are Dalton’s atomic model, Thomson’s atomic model, Rutherford’s atomic model, Bohr’s atomic model, and the quantum atomic model.

The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³
