What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Calculate how many moles of SO2 can be produced with when given 75 grams of CS2.
Now calculate how many moles of SO2 can be produced with when given 96 grams of O2.
Which one is the limiting reactant (75 grams of CS2 or 96 grams of O2)? How do you know?
Answers
Answer:
1. 9600 moles
2. 4096 moles
Explanation:
CS2 + 3 O2=> CO2 + 2 SO2
1. The ratio for CS2: SO2 is :
1:2
If there are 75g of CS2 then there are:
75 × 2= 150g of SO2
Moles = mass × Mr
Moles = 150 × 64
Moles = 9600
2. The ratio for O2 : SO2 is:
3:2
If there are 96g of O2 then there are:
96 × 2/3 = 64g of SO2
moles = mass × Mr
Moles = 64 × 64
Moles = 4096

Se tiene un litronde solucion de agua con alcohol con una consentracion del 4.5% v/v ¿Cuanto alcohol se tiene en la solución
Answers
Answer:
45 mL
Explanation:
Tenemos los siguientes datos:
V = 1 L
C = 4,5% v/v
El porcentaje en volumen (%v/v) expresa el volumen de soluto (alcohol en este caso) que hay cada 100 mL de solución. Si la solución tiene una concentración del 4,5% v/v eso quiere decir que hay 4,5 ml de alcohol cada 100 ml de solución, de acuerdo a lo siguiente:
4,5% v/v alcohol = volumen alcohol/ volumen solución x 100 = 4,5 mL alcohol/100 mL solución= 4,5 mL alcohol/0,1 L alcohol
Por lo tanto, al multiplicar por el volumen total de la solución (1 L), obtenemos la cantidad total de alcohol:
4,5 mL alcohol/0,1 L alcohol x 1 L = 45 mL

Answers
Answer:
gold i believe or possibly bromine
Explanation:
q- how does fluorine react with gold
a- this fluoride compound features gold in its highest known oxidation state. this red solid dissolves in hydrogen fluoride, but these solutions decompose, liberating fluorine.
q- how does chlorine react with gold
a- gold does react with halogens. it'll, for example, react very slowly with chlorine gas at room temperature to form gold chloride, AuCl3. if gold chloride is heated gently, it will decompose to release the pure elements again.
q- how does bromine react with gold
a- gold in bromine solutions dissolves according to electrochemical/chemical (EC) mechanisms. ... in the chemical composition of the mechanism, this monovalent gold bromide disproportionate into gold and stable AuBr −4 , which reports into solution. with respect to pH, there are two characteristic dissolution regions.

Fluorine will be most reactive with gold.
What is fluorine?
Of almost all of the elements, fluorine seems to be the most electronegative as well as reactive. Fluorine would be a diatomic, pale yellow, extremely corrosive, combustible gas with a strong smell. The lightest halogen would that be. It produces oxygen and even the incredibly corrosive hydrofluoric acid when it combines strongly with water.
What is reactive?Reactivity would be a substance's capacity to chemically combine with several other substances. Iron, for instance, reacts vigorously with oxygen.
As you move down the group, the halogens, which are non-metal elements in Group 7, become less reactive. In contrast to the alkali metals within Group 1 of the particular periodic table, this trend is the opposite. One of the most reactive elements in Group 7 was fluorine.

What is the freezing point, in °C, of a solution made with 1.31 mol of CHCl₃ in 530.0 g of CCl₄?
Answers
Answer:
-96.6°C
Explanation:
Given:
moles CHCl3 = 1.31 molmass CCl4 = 530.0 gmass CCl4 = 530.0 g * (1 kg / 1000)
mass CCl4 = 0.5300 kg
First calculate the molality (m) of the solute, which is the moles of solute divided by the kg of solvent ([tex]\frac{moles}{kg}[/tex]):
molality CHCl3 = (mass moles CHCl3) / (mass CCl4 in kg)
molality CHCl3 = (1.31 mol) / (0.5300 kg)
molality CHCl3 = 2.471698m
Decrease in freezing point of solvent = (Kf) * (molality of solute)
Decrease in freezing point of CCl4 = (Kf) * (molality CHCl3)
Decrease in freezing point of CCl4 = (29.8°C/m) * (2.47m)
Decrease in freezing point of CCl4 = 73.6566°C
Then use the molality of the solute to calculate the change in freezing point and subtract the change from the original freezing point.
Freezing point of solution =
(freezing point of pure solvent) - (Decrease in freezing point)
Freezing point of solution = (-22.9°C) - (73.66°C)
Freezing point of solution = -96.6°C

Can carbon and hydrogen form double bonds between them?
Answers
Answer:
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
The carbon-hydrogen bond (C–H bond) is a bond between carbon and hydrogen atoms that can be found in many organic compounds. This bond is a covalent bond meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells making them stable.

A solution has [OH-]=3.5*10^-6. Based on that, what must be true about this solution?
Answers
Answer:
Option B. It is a basic solution.
Explanation:
To know which option is correct, let us calculate the pH of the solution.
First, we shall determine the pOH of the solution. This is illustrated below:
Concentration of Hydroxide ion, [OH¯] = 3.5×10¯⁶
pOH =.?
pOH = –Log [OH¯]
pOH = –Log 3.5×10¯⁶
pOH = 5.5
Finally, we shall determine the pH. This can be obtained as follow:
pOH = 5.5
pH =?
pH + pOH = 14
pH + 5.5 = 14
Collect like terms
pH = 14 – 5.5
pH = 8.5
The pH scale reads as follow:
0 to 6 => Acidic
7 => Neutral
8 to 14 => Basic
Comparing the pH of the solution (i.e 8.5) with the pH scale, we can conclude that the solution is basic because the pH of solution lies between 8 and 14.

The weight of the elephant is 4500 kg, and the area of the sole of one of its legs is 1700 cm2. Calculate the pressure of the elephant on the ground.
Answers
Answer:
64852.94 N/m²
Explanation:
From the question,
P = F/A.................... Equation 1
Where P = Pressure of the Elephant on the ground, F = Weight of the Elephant, A = Area of the sole of the four legs.
But,
F = mg.............. Equation 2
Where m = mass of the elephant, g = acceleration due to gravity
Substitute equation 2 into equation 1
P = mg/A............ Equation 3
Given: m = 4500 kg, A = (1700×4) cm² ( The elephant has four legs) = 6800 cm² = 0.68 m²
Constant; g = 9.8 m/s²
Substitute these values into equation 3
P = (4500×9.8)/0.68
P = 64852.94 N/m²

Answer: The balanced equation is [tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.
For example, [tex]AlCl_{3} + Cs \rightarrow CsCl + Al[/tex]
Here, number of atoms on reactant side are as follows.
Al = 1Cl = 3Cs = 1Number of atoms on product side are as follows.
Al = 1Cl = 1Cs = 1To balance this equation, multiply Cs by 3 on reactant side and multiply CsCl by 3 on product side.
Hence, now the equation will be as follows.
[tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]
Here, number of atoms on reactant side are as follows.
Al = 1Cl = 3Cs = 3Number of atoms on product side are as follows.
Al = 1Cl = 3Cs = 3Thus, we can conclude that this equation is balanced.

Explain how an electric car might still run on fossil fuels.
Answers
Answer:
Explanation:
When you use electricity to charge your car, you can integrate renewable resources like solar into the fueling process. Without solar, your electric vehicle is still effectively running off of fossil fuels – it's just the fossil fuels utilized at the power plant and not within your engine.
Fossil fuels include substances like natural gas, coal, and oil. It is possible for electric cars to run on these fossil fuels. Fossil fuels like coal are burnt up to generate electricity. So when cars run on electricity, they are indirectly tapping into fossil fuels.
As the world continues to seek measures to reduce carbon emissions, electric cars are gradually becoming an option. While it is true that these fossil fuels might not be used directly on electric cars, they still find use indirectly in these cars. When coal is burnt up at the power plant to generate electricity, electric cars tap into fossil fuels indirectly.Learn more here:
