Answer:
The answer would be C) a liquid.
Explanation:
If you were to pour a glass of water into a rectangular container, the water would fill up the container and be in the same shape as the container. That is becuase water flows and it doesn't harden up or take its own shape until it's frozen. The molecules are not tightly secure to each other so they are able to move freely.

A. It lists the different charges metal ions can have.
B. It compares how reactive the metals are.
C. It tells us which metal compounds are soluble.
D. It tells us how good of a conductor a metal is.
An information does the activity series of metals give us that it compares how reactive the metals are. Therefore, option B is correct.
What do you mean by metals ?Metals are lustrous, opaque elements that conduct heat and electricity well. Most metals are malleable and ductile, and they are denser than the other elements.
The term "metal" is thought to have originated during the hippie movement, when "heavy" meant serious or deep. Metal music is defined by several elements, including heavily distorted guitar riffs and chords, powerful drumming, extra low-range bass notes, and aggressive or throaty vocals.

How many joules are released when 30.0 g of H2O(g) condenses at 100°C and cools to 10°C
Heat released : 79086 J
Further explanationCondenses :
1. phase change (gas - liquid) : heat of vaporization (ΔH vap for water = 2260 J/g)
2. cools from 100 - 10 : (Q=m.cΔT)
1. Q=m.ΔH vap
[tex]\tt Q=30\times 2260=67800~J[/tex]
2. Q=mc.ΔT(c water = 4.18 J/g C)

Convert 3.55 moles Nacl to formula units
Answer:
2.14 x 10²⁴ formula units
Explanation:
Given parameters:
Number of moles of NaCl = 3.55moles
Unknown:
Formula units of NaCl = ?
Solution:
A mole of substance contains the avogadro's number of particles. The number of particles could be protons, atoms, neutrons, formula units etc.
1 mole of substance = 6.02 x 10²³ formula units
3.55 mole of NaCl = 3.55 x 6.02 x 10²³
= 2.14 x 10²⁴ formula units

Why does the salt reappear when the water ?
Answer:
Explain that as the water evaporates, water molecules go into the air. The water molecules that evaporate become a gas called water vapor. Only the water evaporates, leaving the sodium and chloride ions behind. The sodium and chloride ions attract each other and re- form salt crystals.

When moving across a row in the Periodic Table, which of the following increases?
Words made from letters of the alphabet are similar to molecules made from atoms. Based on what you already know about matter, which statement best explains this comparison?
A. Atoms can make many different molecules, just like letters can make many different words.
B. Molecules must contain many different atoms, just like words must contain many different letters.
C. There are 26 different atoms that are used to form molecules, just like there are 26 different letters that are used to form words.
D. There are no rules for how letters combine to make words, just like there are no rules for how atoms combine to make molecules.
To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The correct option is option A.
What is atom?
Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit. Atoms can make many different molecules, just like letters can make many different words.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.
Therefore, the correct option is option A that is Atoms can make many different molecules, just like letters can make many different words.

name the compound TiBr3
Answer:
Titanium (III) bromide
Explanation:
As it is an ionic compound we write the valency for transition elements, and that means here that titanium loses three electrons to become +3 (Ti
The name of the compound is titanium (III) bromide as it has titanium in +3 oxidation state.
What is compound?
Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

If I have 13 protons and 12 electrons what is my charge?
Answer:
The charge would be +1
Explanation:
Protons have a positive charge while electrons have a negative charge. Therefore, it's simple subtraction. In every case, subtract the number of electrons from the number of protons.
13 - 12 = 1
Therefore the charge is +1
Here's one more example:
If the element chromium (Cr) has 24 protons and 28 electrons, what is its charge? Remember that protons have a positive charge and electrons have a negative charge.
24 - 28 = -4
Charge = -4
It would be written as followed when associating charge with a specific element: [tex]Cr^{-4}[/tex]
If an element has a neutral charge, that means the number of protons and neutrons are the same. If you look at the periodic table of elements, all of the elements listed have a neutral charge. The 0 isn't showed in the corner because it isn't necessary.
Bonus Information:
This isn't related to your question, but I've come across confusions when it comes to particles. Remember that protons (+) and electrons (-) are the only particles that have a charge, therefore, as it says in it's name, neutrons are neutral or have no charge. Neutrons do not contribute to charge, but they do contribute to the mass of an atom. So the number of protons added to the number of neutrons equate to the mass of an atom. Electrons have mass, but it's so miniscule and insignificant that it doesn't even contribute to the overall mass of the atom, so don't count those.
Remember:
C = p - e
M = p + n
C = atomic charge, M = atomic mass, p =protons, n = neutrons, e = electrons

How could you test your prototype to determine the effectiveness of your spin table? What data could you collect? How many trials would you run?
Answer:
Testing prototypes is an inherent part of finalizing designs. Nobody wants to wonder why users are not utilizing an app the way it should be utilized or why they can’t seem to complete a purchase on your website. And nobody wants to rework something that’s already been shipped.
Conducting tests as early as the prototyping stage can help you avoid these unfortunate scenarios. User research with Qualaroo can help you validate your current design and uncover new areas of focus for the next iteration. Use Qualaroo to understand how people use your interface early on in the design process and evolve your prototype into a working product faster.

A train travels 846 miles in 9 hours. What is the average speed of the train?
Answer:
The answer is 94 miles an hour.
Explanation:
Speed equals distance divided by the time taken to cover that distance. So to find the average speed of the train just divide the distance covered (846 miles) by the time taken by the train to cover that distance (9 hours) and that equals 846/9 equals 94 miles in one hour.
