What is chemical equation?In chemistry, you will frequently come across a chemical equation. It is a textual depiction of the procedure that takes place throughout a chemical reaction using numbers and symbols.
The reactants are placed on the left side of such an arrow in a chemical equation, while the reaction's products are placed on the right. Though certain equations may imply equilibrium with the reaction occurring in both directions simultaneously, the tip of the arrow normally heads toward the right or product side of the equation. Chemicals after the reaction ends during chemical equation.

METHOD 1:
Explanation:
METHOD 2:
Explanation:
Answers
Answer:
METHOD 1: (surface area of a solid reactant) METHOD 2: (concentration or pressure of a reactant)
Explanation:
METHOD 1: (surface area of a solid reactant) Increasing the surface area of a solid reactant exposes more of its particles to attack. This results in an increased chance of collisions between reactant particles, so there are more collisions in any given time and the rate of reaction increases.
METHOD 2: (concentration or pressure of a reactant) Increasing the concentration means that we have more particles in the same volume of solution. This increases the chance of collisions between reactant particles, resulting in more collisions in any given time and a faster reaction. As we increase the pressure of reacting gases, we increase the rate of reaction.

Which statement describes sunspots? A.Sunspots have a bright white appearance. B.Sunspots occur in the radiative zone of the sun. C.Sunspots occur in areas of extremely low magnetic fields. D.Sunspots have lower temperatures than their surroundings.
Answers
Answer:
The statements that describe sunspots is;
D. Sunspots have lower temperatures than their surroundings
Explanation:
Sunspots is a phenomenon that involves temporary appearance of dark areas on the Sun's surface, which are regions of concentrated magnetic field flux which inhibit heat transfer by convection and are therefore cooler than other parts of the Sun. Due to the presence of magnetic field magnetic
Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Opposite magnetic polarity sunspots usually appear as a pair.
Therefore, the statement that best describe sunspots is that a sunspot is a region of reduced temperature compared to surrounding areas on the Sun's surface.

Si Hecho Dos Cubos de Hielo En Un Vaso Con Agua Señalo Donde Quedo El Nivel Del Agua, Luego A Pasar El Tiempo Dejo Que Se Derritan Los Cubos De Hielo El Nivel Del Agua Aumenta??
Answers
Answer:
Ver explicacion
Explanation:
Técnicamente, cuando el hielo se derrite, ocupa aproximadamente el mismo volumen de agua que es igual a la masa de agua desplazada antes de que el hielo se derrita. Esto es posible solo cuando se ignora el cambio en la densidad del agua.
Sin embargo, si tenemos en cuenta el ligero cambio en la densidad del agua, se puede demostrar que el volumen de hielo es mayor que el del agua líquida porque el agua se expande cuando se congela.
Esto significa que el volumen de agua disminuye cuando el hielo se derrite.

Answer:
Explain: In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.
An object has balanced forces acting on it. Which of the following describes the result these balanced forces have on the object? A. It remains at rest or speeds up in the same direction. B. It speeds up in the same direction or moves at constant speed. C. It speeds up in the same direction or slows down. D. It remains at rest or moves at constant speed in the same direction.
Answers
Answer:
C.It remains at rest or moves at constant speed in the same direction.
Explanation:
First, remember the Newton's 1st law of motion which states that the object at rest will remain at rest and that in motion will stay in motion with the same speed and same direction unless acted by unbalance forces.
Balanced forces on an object occur when two forces at act on an object are equal in size and act in opposite direction. In this case, a stationary object will stay at rest while an object moving will continue to move at the same speed and same direction.
An object acted by balanced forces is said to be at equilibrium, thus the state of motion will be maintained.The object will not accelerate. A good example of an object acted by balanced forces is an object at rest or in constant motion such as a car that stopped at red-light signal or a car travelling at a constant speed.
Lab: Limiting Reactant and Percent Yield
Student Guide
Pre-Lab Information
Purpose Explore the yield of a chemical reaction by identifying the limiting reactant, comparing the
theoretical and actual yields, and explaining the sources of error.
Time Approximately 45 minutes
Question While observing a chemical reaction, how can you tell which reactant is limiting?
Reaction The reaction of copper(II) chloride and aluminum is shown in this balanced equation:
3CuCl2 + 2Al 2AlCl3 + 3Cu
Hypothesis If a substance is the limiting reactant, then it will be fully consumed by the time the
reaction completes because it is the reactant that reacts completely and the reaction
cannot proceed further.
Summary You will react copper(II) chloride with different quantities of aluminum in two trials. You
will also calculate percent yield for Trial 2.

fn 35 moles of Iron (Fe)?
Answers
Answer:
6. They all have the same number of molecules.
7. 19.5 g
Explanation:
6. From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ molecules i.e
1 mole = 6.02×10²³ molecules
Considering the question given above, each compounds has just 1 mole. Thus, they will also have the same number of molecules.
7. Determination of the mass of iron (Fe)
Number of mole of Fe = 0.35 mole
Molar mass of Fe = 55.85 g/mol
Mass of Fe =?
Mass = mole × molar mass
Mass of Fe = 0.35 × 55.85
Mass of Fe = 19.5 g
Thus, the mass of 0.35 mole of iron (Fe) is 19.5 g
As altitude increases, what happens to air pressure the choices are it fluctuates, it increases, it decreases or it stays the same
Answers
Answer:
it decreases
Explanation:
It is a common saying the pressure decreases with height. This means that as altitude increases, the pressure of air decreases. The higher you go above sea level, the pressure becomes lesser.
This is as a result of decrease in the amount of air above sea level and hence a decrease in the density of air as altitude increases.
Hence, with increasing altitude, pressure decreases.
Answer:
It decreases
