Which scientist developed the quantum mechanical model of the atom?a. Albert Einstein
c. Niels Bohr
b. Erwin Schrodinger
d. Ernest Rutherford

Answers

Answer 1
Answer:

The quantum mechanical model of the atom was developed by Erwin Schrödinger. The correct option is B

What is Erwin Schrödinger theory?

Austrian physicist Erwin Schrödinger created the quantum mechanical model of the atom in 1926. The development of quantum mechanics, a fundamental physics theory that describes how matter and energy behave at the atomic and subatomic scales, was significantly aided by Schrödinger's work.

The behavior of electrons in atoms was mathematically described by Schrödinger's wave equation, which combined wave-like and particle-like characteristics. His work transformed our understanding of the atomic universe and formed the basis for contemporary quantum theory, along with the contributions of other scientists like Werner Heisenberg and Max Planck.

The temperature of a sample of water increases from 20 degrees Celsius to 46.6 degrees Celsius as it absorbs 5650 calories of heat. What is the mass of the sample

Answers

ΔT = 46.6 - 20

ΔT = 26.6ºC

Specific heat of water is 1.0 cal/g °C

Q = m * C * ΔT 

5650 = m * 1.0 * 26.6

5650 = m * 26.6

m = 5650 / 26.6

m = 212.4 g

hope thips helps!

GIVING BRAINLIEST!!! A student observes a beaker of room temperature water resting on a table. She states that the beaker of water does not have any energy. Which statement below is accurate regarding her observation?a. She is correct because the beaker of water is not moving.


b. She is incorrect because the beaker of water has thermal energy.


c. She is incorrect because all water contains hydrogen and oxygen.


d. She is correct because the beaker of water is at room temperature.

Answers

Answer:

a

Explanation:

im thinking because the water is a room temperature there shouldnt be anm immence amount og heat energy for it to have a good amount of energy tho i could be wrong because its not moving it could have no energy.

Answer: please tell me i have this exact thing on a test rn i need the answer

This is the metric unit for measuring volume

Answers

Cubic metre is the metric unit for measuring volume. The cubic centimetre has a particular nomenclature called a millilitre.

The 3-dimensional space that is occupied by matter or surrounded by a surface is measured in volume, which is expressed in cubic units. A derived unit called the cubic metre serves as the SI unit of volume.

A unique designation for the cubic decimeter is the litre. To reduce the chance of confusion between the lowercase letter "ell" (l) and the number one (1), the symbol for the litre is an uppercase letter "ell". The litre cannot be represented by the script letter l (l).

Which of the following explains the importance of the activation energy acting as a barrier for reactants?

Answers

The energy needed for a chemical reaction is called the activation energy. This energy is to be present in order for the reaction to happen. This can be achieved by supplying or releasing heat from a system of reactants. This can achieved faster by using a catalyst.

Can someone how to do these problems!!

Answers

You can use the follwing equations.
pH=14-pOH
pOH=-log[OH⁻]

a)  pOH=-log10⁻¹²
     pOH=12
     pH=14-12
     pH=2

You can also use these equations:
[H⁺]=K(w)/[OH⁻]    (K(w)=1.01×10⁻¹⁴)
pH=-log[H⁺]

b) [H⁺]=(1.01×10⁻¹⁴)/10⁻²M
    [H⁺]=1.01×10⁻¹²M²
    pH=-log(1.01×10⁻¹²)
    pH=12

You can use either method.  It does not really matter.
I hope this helps.  Let me know if anything is unclear and when you do the calculations for c you should get pH=7.
