What is the difference between a continuous spectrum with an emission line spectrum?
Answer: A Continuous spectrum is a spectrum that has all wavelengths with no gaps over a wide range. An Emission spectrum is when an electron in an excited state moves to a lower energy level, it emits a certain amount of energy as photons.

calculate the mass of 3.011×10^24 molecules of water...................... plzz i need it asap plzz help me plzz
Answer:
90.10 g
Explanation:
Step 1: Given data
Number of molecules of water: 3.011 × 10²⁴ molecules
Step 2: Calculate the moles corresponding to 3.011 × 10²⁴ molecules of water
We will use Avogadro's number: there are 6.022 × 10²³ molecules of water in 1 mole of molecules of water.
3.011 × 10²⁴ molecules × (1 mol/6.022 × 10²³ molecules) = 5.000 mol
Step 3: Calculate the mass corresponding to 5.000 moles of water
The molar mass of water is 18.02 g/mol.
5.000 mol × 18.02 g/mol = 90.10 g

What do a hypothesis and scientific law?
Answer:
If you mean "What is a hypothesis and the scientific law?" than hypothesis means a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation and scientific laws or laws of science, are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. The term law has diverse usage in many cases across all fields of natural science.
Answer:
If you mean "What do hypothesis and scientific law have in common" than a hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept.

A milkman adds a very small amount of baking soda to fresh milk.
(a) Why does he shift the pH of the fresh milk from 6 to slightly alkaline?
Answer:
Curd is acidic in nature, because an acidic substance has less value of pH. A milkman adds a very small amount of baking soda to fresh milk. Why does he shift the pH of the fresh milk from 6 to slightly alkaline? Answer: By making the milk more alkaline, it takes more time to turn into curd.

How do you determine the charge of an isotope?
Answer:
If the protons in the atom outnumber the electrons, the isotope has more positive charges than negative charges but If the number of electrons exceeds the number of protons, the ion charge will be negative.
Explanation:
The charge of an isotope is defined by how many more protons there are than electrons.
Or the other way around.
For example if there are 4 protons and 2 electrons, the ion charge is +2 because there are more protons.
If there are 4 electrons and 2 protons, the ion charge is -2 because there are more electrons.
In what circumstance would the complete and net ionic equations for a reaction be identical?
Answer: Complete ionic equations dissociate all aqueous solutions into ions. Net ionic equations show the change that occurs in chemical reactions and do not show spectator ions that are the same in reactants and products. (b) If no spectator ions were present then complete and net ionic equations would be identical.

How many joules of heat are needed to raise the temperature of 10.0 g of aluminum from 22°C to 55°C, if the specific heat of aluminum is 0.90 J/g°C?
Answer:
0.90 degree C
Explanation:
The key to this problem lies with aluminium's specific heat, which as you know tells you how much heat is needed in order to increase the temperature of 1 g of a given substance by 1∘C
In your case, aluminium is said to have a specific heat of
0.90 J g∘ C.

Answer: ¹²₅C
Explanation:
¹²₅C is incorrect. The superscript is the atomic mass. This varies between each element. The subscript is the atomic number. This doesn't change. You will see every element has the correct atomic atomic number except for Carbon. Carbon should have atomic number 6.

What is the density of 19 milliliters of a liquid substance with a mass of 6.05 grams?
Answer:
The answer is
0.32 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} [/tex]From the question
mass = 6.05 g
volume = 19 mL
The density of the substance is
[tex]density = \frac{6.05}{19} \\ = 0.3184210526...[/tex]
We have the final answer as
0.32 g/mLHope this helps you

Answer:
Explanation:
So basically is just explain what radioacitvity and then radidoactive
Radioactivity is the spontaneous release of energy from an unstable atom to get to a more stable state. Ionizing Radiation is the energy that comes out of a radioactive atom. Radioactive isotopes are radioactive atoms of the same element that have different numbers of neutrons.
