Which scenario involves a reaction that is at equilibrium?
A)The reaction is only producing products.
B)The reaction is producing more reactants than products.
C)The reaction is producing more products than reactants.
D)The reaction is producing reactants and products at an equal rate.
PLEASE HELPP AND QUICK!!! I WILL GIVE BRAINLIST!!
D)The reaction is producing reactants and products at an equal rate.
The scenario which involves a reaction at equilibrium is; The reaction is producing reactants and products at an equal rate. Option D is correct.
At equilibrium, the forward and reverse reactions of a chemical reaction occur at the same rate. It means the rate of formation of products from reactants is equal to the rate of formation of reactants from products. There is no net change in the concentrations of reactants and products over time, and the system is in a stable state. The concentrations of both reactants and products remain constant, and the reaction appears to have stopped.
In simple terms, at equilibrium, the reaction is balanced, and there is no preference for the formation of either reactants or products. The forward and reverse reactions are happening simultaneously at an equal rate, resulting in a dynamic balance between reactants and products. This state is represented by a double-headed arrow in chemical equations, indicating that the reaction is reversible and at equilibrium.
Hence, D. is the correct option.

Given the following balanced chemical equation, 2 NaClO3 → 2 NaCl + 3 O2, how many moles of O2 will be produced from 8.21 moles of NaClO3?
Answer:
12.3 mo
Explanation:
Given the following balanced chemical equation, 2 NaClO3 → 2 NaCl + 3 O2, how many moles of O2 will be produced from 8.21 moles of NaClO3?
for every 2 moles of NaClO3, you produce 3 moles of O2.
so for O2 you produce 3/2 the moles of NaClO3
so 8.21 moles of NaClO3 will produce 8.21 X 3/2 moles of O2
=12.3 mole

How many protons? How many neutrons? What is the name of this atom?
its a k12 test question TwT
Answer:
Explanation:
ALRIGHT EPIC GAMER IM GONNA INTRODUCE YOU TO THE AWESOME WORLD OF THE PERIODIC TABLE
look at this
6
C
Carbon
12.011
ok so this is what one block on the periodic table looks like
the protons and electrons are going to be the smaller number
so the protons and electrons for carbon are 6
but your question does not ask for electrons so its fine.
How many protons? LOOK AT THE SMALLER NUMBER IN ELEMENT BLOCK ON PERIODIC TABLE.
How many neutrons? Take the bigger number and subtract the smaller number from it. so it would be for carbon: 12.011 - 6 = 12 neutrons.
to find the name of the atom, just count the number of electrons and then look for the element with the same number to find the name

A sample of 10.5 g of nitrogen reacts with 20.2 g of hydrogen to produce ammonia.
3H2 (g) + N2 (g) → 2NH3 (g)
I need help answering these questions
The mass of NH₃ produced in the reaction of 10.5 g of nitrogen and 20.2 g
of hydrogen is 12.75 g
The balanced chemical equation is represented as follows:
3H₂ (g) + N₂ (g) → 2NH₃ (g)
Knowing the limiting reagent will assist us to ascertain the amount of Ammonia produced.
Therefore,
mass of H₂ = 20.2 g
molar mass = 2g/mol
moles = 20.2 / 2 = 10.1 moles
10.1 / 3 = 3.36666666667
mass of N₂ = 10.5 g
molar mass N₂ = 28 g /mol
moles = 10.5 / 28 = 0.375 moles
0.375 / 1 = 0.375
Therefore, nitrogen is the limiting reagent and it will determine the amount
of product formed.
28 g of N₂ gives 2(17) g of NH₃
10.5 g of N₂ will give ? of NH₃
cross multiply
mass of NH₃ produced = 10.5 × 34 / 28
mass of NH₃ produced = 357 / 28
mass of NH₃ produced = 12.75 g

Frases con masa atómica
Answer:
Si ha mirado una tabla periódica, es posible que haya notado que la masa atómica de un elemento rara vez es un número par. Dupdo
Un Dalton, también conocido como unidad de masa atómica, es aproximadamente la masa de un solo protón o neutrón. Dupdo
Es decir, el deuterio tiene el doble de masa atómica que el protio y el tritio tiene tres veces la masa atómica del protio. Dupdo
El número bariónico, que es equivalente al número de masa atómica, debe permanecer constante para que se produzca una reacción.

Using the formula F = (9/5)C + 32, convert 17°C into Fahrenheit. A. 41.4°F B. 50.8°F C. 60.2°F D. 62.6°F
Answer:
D. 62.6°F
Explanation:
F = (9/5)C + 32
We know that C = 17°, so:
F = (9/5)(17°) + 32
9/5 = 1.8 and 1.8 * 17 = 30.6
F = 30.6° + 32
F = 62.6°
