Which of the following is an example of a science occupation that studies non living systems? A) physical scientists B) life scientists C) natural science technicians D) biological technicians

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.

Answer: 64

Explanation:

you just multiple the 3 numbers to get the answer (i’m in chemistry and just did this question lol)

Answer:

A

Explanation:

the circles are more tightly packed together in box A than in box B in the same amount of space

Explanation:

Force = Mass × Acceleration

20 = 2.0 × A

A = 20/2 = 10m/s^2

Answer:

For me, it is balanced

Explanation:

Because the amount of element Zn reaction is equal the production. Also as the amount of Hydrogen and Chloride in the reaction and the production are equal.

Explanation:

The density of a substance can be found by using the formula

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

Hope this helps you

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.

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

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.

Answer # Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.

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:

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.

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.

I found this information off of a site called “socratic.org.” I hope i could help!

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.

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.
