When you dissolve an antacid tablet in water and it produces bubbles, what kind of change is this?
A. a physical change
B. a chemical change
C. a solution change​

Answer:Beta

Explanation:

I watched the video and I got it wrong, the right answer was beta. I can’t explain why because I’ve already forgotten lol

Digestive tract have digestive enzymes which are not able to break beta linkages as  humans do not have enzymes which breakdown beta linkages.

It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.

The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.

Answer:

Number of moles = 2.72 mol

Explanation:

Given data:

Number of moles of H₃PO₄ present = ?

Molarity of solution = 18.1 M

Volume of solution = 150.0 mL (150/1000 = 0.15 L)

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

By putting values,

18.1 M = number of moles / 0.15 L

Number of miles = 18.1 M × 0.15 L

Number of moles = 2.72 mol

Answer:constant acceleration. A steady change in velocity.

Explanation:

Moles of Oxygen produced : 4.5 moles

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

The reaction coefficient shows the mole ratio of the reactants and products

Reaction

2KCIO₃ → 2KCl + 30₂

moles of KCIO₃ = 3

From equation, mol ratio of KCIO₃ : O₂ = 2 : 3, so mol O₂ :

[tex]\tt mol~O_2=\dfrac{3}{2}\times 3=4.5[/tex]

Answer:

ΔE  = 13.056 ev

Explanation:

Energy associated with nth state is,

En =  -13.6/n²

For n = 1

E₁ = -13.6 / 1²

E₁ = -13.6/1

E₁ = -13.6 ev

Kinetic energy of electron = -E₁ = 13.6 ev

For n = 5

E₅ = -13.6 / 5²

E₅ = -13.6/25

E₅ = -0.544 ev

Kinetic energy of electron = -E₅ = 0.544 ev

Wavelength of radiation emitted:

ΔE = hc/λ = E₅ - E₁

by putting values,

ΔE  = -0.544ev  - (-13.6 ev  )

ΔE  = 13.056 ev

Answer:

c

Explanation:

because the left side of reactant is take more time to make a product than the first

The rate of these reactions should be considered as the option b. The rate of reaction A is lower.

Since Reaction A is completed in 12 seconds, and reaction B is completed in 21 seconds.

So based on this, we can say that the rate of reaction A should be lower as it contain 12 seconds as compared to reaction b.

hence, the option b is correct.
