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. Therefore, 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.
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. Just like the N and S poles on bar magnets, electrons and protons attract each other.
Therefore, the correct option is option A.

Which description below is most consistent with what you can expect from the ball's motion?
The ball will roll as high as Position 1 since energy cannot be created or destroyed.
The ball will roll past Position 1 since energy cannot be created or destroyed.
The ball will roll as high as Position 2 since some of the energy will be transformed to heat,

What can help overcome a positive enthalpy of solution and allow a solid
solute to dissolve in water?
A. A decrease in entropy
B. A large amount of energy released
C. A large amount of energy absorbed
D. An increase in entropy
Answer: D. An increase in entropy
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an disordered arrangement to an ordered arrangement, the entropy is said to increase and vice versa.
For a reaction to be spontaneous, the enthalpy of the solution must decrease and the entropy must increase.
To overcome a positive enthalpy of solution and allow a solid solute to dissolve in water, an increase in entropy would make the reaction spontaneous as the system would move to a more disordered state.
How many grams of MgO are in 3.500 moles?
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, lead has the highest mass. 141.05gram of MgO are in 3.500 moles.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. 141.05gram is the mass of MgO.
Mathematically, the molar mass, mole and given mass can be related as
Mole of MgO =given mass of MgO ÷ molar mass of MgO
Molar mass of MgO= 40.30 g/mol
Mole of MgO= 3.500 moles
substituting the values, we get
3.500 moles = mass of MgO÷ 40.30 g/mol
Mass of MgO=141.05gram
Therefore, 141.05gram of MgO are in 3.500 moles.

Explaining Radioactive Decay
Explain the process of radioactive decay. What happens during radioactive decay, and what is the result at the end of radioactive decay?
Answer:
Radioactive decay is the process in which the nucleus of an unstable isotope spontaneously changes, releasing particles and energy. An unstable isotope will continue to decay until it reaches the stable form of either a different isotope of the same element that is stable or a different element that is stable.

Pls help, How is stoichiometry used to calculate amounts of substances in a chemical reaction?
Answer:
Thus, to calculate the stoichiometry by mass, the number of molecules required for each reactant is expressed in moles and multiplied by the molar mass of each to give the mass of each reactant per mole of reaction. The mass ratios can be calculated by dividing each by the total in the whole reaction.
Explanation: Stoichiometry is the field of chemistry that is concerned with the relative quantities of reactants and products in chemical reactions. For any balanced chemical reaction, whole numbers (coefficients) are used to show the quantities (generally in moles ) of both the reactants and products.

When 3243. grams of iron (III) chloride are reacted with 511.8 grams of hydrosulfuric acid, which is the limiting reactant?
2 FeCl3 + 3 H2S -----> Fe2S3 + 6 HCl
Answer:
Hydrosulfuric acid will act as limiting reactant.
Explanation:
Given data:
Mass of iron(III) chloride = 3243.0 g
Mass of hydrosulfuric acid = 511.8 g
Limiting reactant = ?
Solution:
Chemical equation:
2FeCl₃ + 3H₂S → Fe₂S₃ + 6HCl
Number of moles of iron(III) chloride:
Number of moles = mass/molar mass
Number of moles = 3243.0 g/ 162.2 g/mol
Number of moles = 20 mol
Number of moles of hydrosulfuric acid:
Number of moles = mass/molar mass
Number of moles = 511.8 g/ 34.1 g/mol
Number of moles = 15 mol
Now we will compare the moles of both reactant with products
FeCl₃ : Fe₂S₃
2 : 1
20 : 1/2 ×20 = 10
FeCl₃ : HCl
2 : 6
20 : 6/2 ×20 = 60
H₂S : Fe₂S₃
3 : 1
15 : 1/3 ×15 = 5
H₂S : HCl
3 : 6
15 : 6/3 ×15 = 30
Hydrosulfuric acid producing less number of moles of product thus, it will act as limiting reactant.

What is the answer for number 2?
Answer:
It has mass but no charge.
Explanation:
The question asks to describe ONE of the subatomic particles that could be found at location X in the model, so you should think of protons and neutrons. Now all of the answers do NOT describe a proton, but the first answer describes a neutron. Neutrons have mass but no charge. Why? The neutron has two down quarks and one up quark, down quarks, have a charge of -1/3, and up quarks have a charge of +2/3. Doing the math, you'd see that (-1/3)2+2/3 is equal to a neutral charge. So a neutron WILL have a mass, but will NOT have a charge, as they are used to hold the nucleus together.

when you burn wood in a campfire, ____ energy is converted to ____ and light energy.
Answer:
when you burn wood in a campfire, chemical energy is converted to heat and light energy.
Explanation :
When wood is burned stored potential energy ( in the form of chemical energy ) in the log is released due to heating by other excited atoms . This process is called combustion and requires presence of oxygen. So, combustion can be defined as a process which changes chemical energy into kinetic energy in the form of heat. In case of combustion an organic say wood in this case combines with oxygen present in the atmosphere to give off carbon dioxide, water and energy in the form of heat and light .
