Alloys are often stronger and less active than pure metals. Alloys have higher melting point than pure metals.
Use the equation to answer the question.
CH4 + _____Cl2 → CCl4 + _____HCl
Which numbers balance this equation?
The whole Balanced Reactions Quick Check for Honors Chemistry A is
1) A. The reactants and products have the same number and type of atoms, but the atoms may be recombined.
2) B. It shows how many molecules there are of a particular substance.
3) D. NaOH + HCl → NaCl + H2O
4) A. Atoms always remain intact during chemical reactions.
5) D. 4, 4
The balanced chemical equation is:
CH₄ + 4Cl₂ —> CCl₄ + 4HCl
The numbers that balanced the equation are: 4, 4
To know the number that balanced the equation, we shall simply balance the equation.
CH₄ + Cl₂ —> CCl₄ + HCl
There are 4 atoms of H on the left side and 1 atom on the right side. It can be balance by writing 4 before HCl as shown below:
CH₄ + Cl₂ —> CCl₄ + 4HCl
There are 2 atoms of Cl on the left side and a total of 8 atoms on the right side. It can be balance by writing 4 before Cl₂ as shown below:
CH₄ + 4Cl₂ —> CCl₄ + 4HCl
Now, the equation is balanced
The numbers that balanced the equation are 4,4

How does the chemical structure of ionic liquids make them more flexible for scientists to use and what will most likely be the first industrial application of them?
Explanation:
Ionic liquids offer numerous advantages over conventional organic solvents for carrying out organic reactions, Malhotra notes. "In many cases, product recovery is easier, catalysts can be recycled, and the ionic liquids can be reused," he says. "In addition, their thermodynamic and kinetic behavior is different.
Which sphere protects Earth’s surface?
atmosphere
biosphere
geosphere
hydrosphe
Answer:
Hiii
Explanation:
Your answer is Atmosphere
The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and warming the surface through heat retention (the greenhouse effect). The atmosphere is further classified into multiple layers by temperature, which include the thermosphere, the mesosphere, the stratosphere, and the troposphere.

Elements have different properties because they are made up of different types of
atoms.
Right a 5 sentence paragraph explaining this!!!
Answer:
,
Explanation:
Answer:
An atom is the smallest partical in the universe that makes up everything you see around you. Every chemical element is also made up of atoms. Since atoms are what give each element their defining characteristics, each element can be composed of multiple atoms but you must have all of the same type of atoms combined in order for it to be considered an element. For example the element gold can only contain gold atoms. If you mix the atoms of one element with the atoms of another your substance has then been changed from an element to a compound.

why is beryllium-8 different from beryllium-9 in terms of the nuclear particles?
Answer:
Beryllium-8 (8Be, Be-8) is a radionuclide with 4 neutrons and 4 protons. It is an unbound resonance and nominally an isotope of beryllium. It decays into two alpha particles with a half-life on the order of 10−16 seconds; this has important ramifications in stellar nucleosynthesis as it creates a bottleneck in the creation of heavier chemical elements. The properties of 8Be have also led to speculation on the fine tuning of the Universe, and theoretical investigations on cosmological evolution had 8Be been stable.

Que instrumentos de laboratorio usaron luis y Juan?
Luis y Juan querían hacer una investigación sobre la rapidez de disolución de una pastilla efervescente en el ácido acético a temperatura caliente. Para esto, tenían que triturar la pastilla y luego utilizar solamente 15 gramos de la sustancia. Tenían que medir 50 ml de ácido acético y colocar el mismo en un recipiente donde se pueda calentar sustancias, pero que el vapor generado se libere rápido. Al agregar ambas sustancias al recipiente de vidrio, lo comenzaron a calentar. Una vez se iba calentando, agitaron las sustancias poco a poco y con mucho cuidado, tomaron los cambios en temperatura de cada 2 minutos. Al finalizar el experimento, ellos compartieron sus resultados con sus compañeros de clase.

Read the article by Michael Fumento, writer for the New York Post editorial blog, who does not support global warming.
Back in 2005 I and others reviewed the entire hurricane record, which goes back over a century, and found no increase of any kind. Yes, we sometimes get bad storms—but no frequently now than in the past. The advocates simply ignored that evidence.
Fact is, the earth was cooling and warming long before greenhouse gases could have been a factor. The [global warming supporters] have been proved wrong time and time again.

What does it mean to say that a wave is cyclic, or periodic, disturbance?
Answer:
Wave is a disturbance or energy that propagate through medium from one point to other point
So basically it is a flowing energy that flows into the medium and hence medium particles start oscillating about their mean position to and fro.
This motion of medium particles or this to and fro motion is about their mean position and this will always be cyclic or periodic motion
This means the disturbance or energy continuously flow through the medium such that it will change the position of medium particle and this will be cyclic in order
For an example
y(x,t) = Asin(kx - ωt + φ)
So here above equation of wave is a travelling wave in which displacement of medium particle from its mean position is given by "y"
Now we can see that this disturbance depends upon the sine function and it will repeat its same position after every 2 pi time interval as it is cyclic function for this value
Due to this phenomenon of repetition of its same position we can say that it is disturbance of wave is cyclic.
