You place 12.0 milliliters of water in a graduated cylinder. Then you add 15.0 grams of metal to the water and the new water level is 13.91 milliliters. What is the density of the metal in grams per milliliter?

Answers

Answer:

The answer is 7.85 g/mL

Explanation:

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

[tex]density = \frac{mass}{volume} \\ [/tex]

volume = final volume of water - initial volume of water

volume = 13.91 - 12 = 1.91 mL

We have

[tex]density = \frac{15}{1.91} \\ = 7.853403141...[/tex]

We have the final answer as

7.85 g/mL

Hope this helps you

It's important to remember that elements are

Answers

No, unless you're doing some sort of course where they demand that you do. It's useful to remember the general features of the periodic table (what each block is, where they are in relation to each other, roughly where the most common elements are), but memorizing the entire thing would simply be a mnemonic exercise

What does electronegativity measure

Answers

Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

1) What is the ground state electron configuration for Oxygen (O)?
2) What is the excited state electron configuration for Oxygen (O)
Help please

Answers

Answer:

1)Oxygen atoms have 8 electrons and the shell structure is 2.6. The ground state electron configuration of ground state gaseous neutral oxygen is [He]. 2s2. 2p4 and the term symbol is 3P2.

Explanation:

2)If the element were to become excited, the electron could occupy an infinite number of orbitals. However, in most texts the example will be the next available one. So for oxygen, it might look like this: 1s22s22p33s1 - where the valence electron now occupies the 3s orbital in an excited (i.e. not ground) state

Which of the following is an example of chemical weathering?
Frost wedging
O Animal activity
Plant growth
O Acid rain

Answers

Answer: acid rain

Explanation: Acid rain is one way in which rocks can be chemically weathered. It can harm forests and crops, damage bodies of water, and contribute to the damage of statues and buildings. In this activity you will simulate the chemical weathering of limestone, which is a soft, sedimentary rock that reacts easily to acid rain.
