State and explain the three basic properties of element
Answer: Some are solid, some are gaseous, a few are liquid. Some are metallic: they have a peculiar lustre; some are coloured (like sulfur) or colourless. Some have a low density; some have a high density. Some are malleable and ductile; some are brittle. Some conduct electricity and heat well; some don’t.
Many metals tend to have structural uses. Nonmetallic elements less so.
Metals tend to have crystal forms featuring close-packed centro-symmetrical structures. Nonmetallic elements tend to have crystal structures featuring more open and directionally packed structures.
Some are especially toxic; some are essential to life; some are both depending on exposure level.
Most are stable; some are less so.
Some elements are highly reactive; some are almost inert (helium, neon, and argon may be completely inert in ambient conditions).
Many metals have basic oxides; quite a few oxides of nonmetallic elements form acids when they are dissolved in water. Some elements can go both ways.
There are many generalisations you can make about metallic and nonmetallic elements, and quite a few exceptions at the margins.
Explanation:
State and explain the three basic properties of element.
Answer :-Some properties of an element can be observed only in a collection of atoms or molecules of the element. These properties include color, density, melting point, boiling point, and thermal and electrical conductivity.

The difference between the potential energy of the products and the potential energy of the reactants is *
Change in entropy
Heat of reaction
Activation energy
Reaction complex
Answer: Heat of reaction
Explanation:
Change in entropy is the difference between the entropy of products and the entropy of reactants.
Heat of reaction is the energy released or absorbed during the course of the reaction. It is difference between the potential energy of the products and the potential energy of the reactants.
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
Reaction complex is the short lived intermediate formed when reactants are coverted to products.

How will popcorn protect a egg by reducing the force of impact on the egg? How does it work?
Answer:
The popcorn will take less impact because the force goes into the popcorn serving as a cushion for the egg. The egg will take less damage because the force will cancel out.

Determine the volume of the product containing carbon produced when 15.0 g of C2H2 are reacted with an excess of oxygen gas
Answer:
25.8 L
Explanation:
Step 1: Write the balanced equation for the complete combustion of acetylene
C₂H₂ + 2.5 O₂ ⇒ 2 CO₂ + H₂O
Step 2: Calculate the moles corresponding to 15.0 g of C₂H₂
The molar mass of C₂H₂ is 26.04 g/mol.
15.0 g × 1 mol/26.04 g = 0.576 mol
Step 3: Calculate the moles of CO₂ produced from 0.576 moles of C₂H₂
The molar ratio of C₂H₂ to CO₂ is 1:2. The moles of CO₂ produced are 2/1 × 0.576 mol = 1.15 mol.
Step 4: Calculate the volume corresponding to 1.15 moles of CO₂
At standard temperature and pressure, 1 mole of CO₂ occupies 22.4 L.
1.15 mol × 22.4 L/1 mol = 25.8 L
A sample of gas at 300k has a volume of 2 liters at what temperature will the volume decrease to 1 liter if the pressure is kept constant
Answer:PV=nRT ideal gas law
P presdure
V volume
n number of moles of gas
R gas constant
T temperature
Explanation: V=nRT/P
2liters=nR300k/P
divide by 2 for the equation
1liters=nR150k/P
with nR remaining constant

Looking for fresh, preservative-free food? Look no further!
How many grams are there in 1x10^24 molecules of BCl3? I use 117.17 as the molecular weight.
Did you try approaching this problem with dimensional analysis?
We know:
1×1024 molecules
117.17 g/mol
And we want our answer to be in g.
molecules ×gmolדconversion factor"=g
The conversion factor has to have units of
molmolecules in order for everything to work out.
What property do you know that has units of molmolecules?
I don’t know of any, but I do know that Avogadro’s number has units of moleculesmol. So for our conversion factor, we divide by Avogadro’s number, which is the same thing as multiplying by its inverse.
1×1024 molecules×117.17 gmol×mol6.022×1023molecules=
The “molecules” units cancel. The “mol” units cancel. Leaving us with “g”. The dimensions (units) work out. Now just do the math with the numbers.
