Explanation:
C3H8 + 5O2 = 3CO2 + 4H2O
Carbon = 3 on both sides
Hydrogen = 8 on both sides
Oxygen = 10 on both sides
The balanced chemical equation for C₃H₈ + 5O₂ = 3CO₂ + 4H₂O
What is a balanced chemical equation?A balanced chemical equation is one in which several reactants are equal to several products.
The formulas for the reactants and products are used to create a balanced equation that represents a chemical reaction. It displays how many units of each chemical were used.
The left and right sides of the reaction arrow of a balanced equation have an equal number of each type of atom.
The reactants and products are placed on the left and right sides of the arrow, respectively, to create a balanced equation.
Carbon = 3 on both sides
Hydrogen = 8 on both sides
Oxygen = 10 on both sides
Therefore, The balanced chemical equation for C₃H₈ + 5O₂ = 3CO₂ + 4H₂O.

if 0.400 moles CO and 0.400 moles O2 completely react how many grams of CO2 are produces?
2CO+O2 becomes 2CO2
Answers
If 0.400 moles CO and 0.400 moles O2 completely react, 17.604 grams of CO2 would be produced.
First, let us look at the balanced equation of reaction:
[tex]2CO + O_2 ---> 2CO_2[/tex]
According to the equation, the mole ratio of CO and O2 is 2:1. But in reality, the mole ratio supplied is 1:1. Thus, CO is the limiting reactant while O2 is in excess.
Also from the equation, the ratio of CO consumed to that of CO2 produced is 1:1. Thus, 0.400 moles of CO2 would also be produced from 0.400 moles of CO.
Recall that: mole = mass/molar mass
Therefore, the mass in grams of CO2 that would be produced from 0.400 moles can be calculated as:
Mass = mole x molar mass
= 0.400 x 44.01
= 17.604 grams

What happens if an atom has a different amount of electrons than protons? (Select all that apply) A: The particle is no longer an atom. B: The particle becomes a different element. C: The particle has a charge. D: The particle is considered an ion.
Answers
What will happen in a case there is different number of electrons compare to protons is D: The particle is considered an ion.
An ion can be regarded as atom or molecule which posses some amount of electron more than amount of protons and vice versa. It can be regarded as molecules that has a charge. i.e ( -ve or +ve)When the number of electron in this molecules or atom is more that that of the present protons, then the ion is negatively charged ion.When a particles posses less electron compare to the present protons then the ion is positively charged.
Therefore, an ion can be charged positively and it can be charged negatively

What is the process whereby stars create elements heavier than hydrogen?
atomic growing

nucleosynthesis
hydrogenation
Answers
Answer:
nucleosynthesis
Explanation:
The correct answer is nucleosynthesis.
How do stars create heavier elements?After the hydrogen in the star's core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen, and so on, until iron and nickel are formed. Up to this point, the fusion process releases energy. The formation of elements heavier than iron and nickel requires an input of energy.
What was the process of the formation of heavy elements?In a supernova explosion, neutron capture reactions take place (this is not fusion), leading to the formation of heavy elements. This is the reason why it is said that most of the stuff that we see around us comes from stars and supernovae (the heavy elements part).

Liquid octane CH3(CH2)6CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 3.43 g of octane is mixed with 7.0 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to significant digits.
Answers
Answer:
88 gram is the answer in 2 significant digits
One mole of octane gives 9 moles of water. Then, 3.43 g or 0.03 moles of octane will give 0.27 moles of water that is 4.86 g of water can be produced.
What is combustion reaction ?Combustion is a type of chemical reaction in which a gas reacts with oxygen to give carbon dioxide and water.
The combustion reaction of octane is given as follows:
[tex]\rm C_{8}H_{18} + \frac{25}{2}O_{2} \rightarrow 8CO_{2} + 9 H_{2}O[/tex]
As per this balanced chemical equation, one mole or 114 g of octane gives 9 moles of water.
no.of moles in 3.4 g of octane = 3.4 g/114 g = 0.03 moles.
no.of moles of water produced from 0.03 moles of octane :
= (0.03 × 9) = 0.27 moles.
Molar mass of water = 18 g/mol
then, mass of 0.27 moles = 0.27 × 18 =4.86 g.
Therefore, the maximum mass of water that could be produced here is 4.86 g.

when an electron moves from a higher orbit to a lower one does it always follow the same path explained
Answers
Yes, electron follows the same path when it absorb and loses energy.
Yes, when an electron moves from a higher orbit to a lower orbit it always follow the same path as it moves from a lower orbit to a higher orbit. When electron absorb energy it has the power to move from lower orbit to higher orbit or energy level.
While on the other hand, when an electron loses that energy, it comes back to its original position from which it moves earlier when it absorb energy so we conclude that electron follows the same path when it absorb and loses energy.

Because after 2p6 the rest does follow the rule of ground state format. Therefore it does make sense.
The given electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d⁸ is the Nickel (Ni). Therefore, option (B) is correct.
What is an electronic configuration?The electron configuration can be explained as electrons being filled in different energy levels of an atom of a particular element. In the electron configuration, the number of electrons is usually written as a superscript of atomic subshells. For example, the electron configuration of Oxygen is written as 1s²2s²2p⁴.
The sequence of fully filled subshells that correspond to the electronic configuration of a noble gas is denoted by square brackets. The principal quantum number (n) can be used to evaluate the maximum number of electrons in an electron shell.
The value of 2n² is given the maximum number of electrons. The atomic orbitals at low energy must be filled first occupying an orbital with a higher energy level.
The total number of electrons filled in the given electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d⁸ is 28. The atomic number of Nickel is 28 therefore it is the configuration of Nickel.
