Answer:
1)Reactants
2)Light
3)An item that can increase reaction rates
4)Reactants must collide with each other
Less molecules lower the chance for collisions
The more collisions there are the higher the reaction rate

When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced. Manganese oxide was not used up in the reaction. Which of the following is likely to increase the rate of the reaction? (5 points)
Reducing the mass of the cube
Using a smaller amount of solution
Smashing the cube into pieces
Chilling the hydrogen peroxide solution
Answers
Answer:
Smashing the cube into pieces
Explanation:
The reason for this is that if we were to smash the cube we would have a larger surface area which means more manganese oxide would be dissolving per second which means we would have a faster reaction rate where if we were to chill the peroxide it would dissolve slower which in turn slows the reaction. For example a spoonful of granulated sugar will react with water faster than a sugar cube.
The rate of the reaction is increased by smashing the cube into pieces. C is the correct answer.
What is the reaction rate?The reaction rate, also known as the rate of reaction, is the rate at which a chemical reaction occurs.
It is typically classified as proportional to the change in product concentration per unit time and the change in reactant concentration per unit time. Different chemical reactions have different reaction rates.
The amount of reactants, the temperature, and the catalyst all influence the reaction rate.
When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced, just as in the given reaction. The reaction did not deplete manganese oxide.
The reaction will be altered by smashing the cube into pieces as the it can boost appropriate conditions for the reaction.
Thus, C is the correct answer.

Help please!!!!!!!!!!!!
Answers
Answer:
D
Explanation:
Gases have low densities. Density is the mass of an object divided by its volume. Mass of gases are quite small. Since the mass is related to mass of the particles itself. However the volume is great since the gases are far apart due to how weak the forces of attraction are ( gases take the shape of the container which means they take up a good bit of space which means greater volume). A small mass divided by a large volume gives a small value (small density).

which statment explains the relationship between Earth's mantle and the outer core
A. the outer core is more dense and farther from the surface than the mantle
B. the outer core is more dense and closer to the surface the mantle
C. the outer core is less dense and closer to the surface than the mantle
D. the outer core is less dense and farther from the surface the. the mantle
Answers
Answer: A. the outer core is more dense and farther from the surface than the mantle
Explanation: There are two mantle‘s. But both of them are closer to the surface than the outer core. the outer core is the liquid layer outside of the inner core. The mantle is the next layer after the outer core. It goes: inner core, outer core, stiffer mantle, asthenosphere, ridged mantle, then the earth’s crust.
En un tomo neutro el numero atomico es al numero de netrones como 7 es a 5 . si el numero de masa es 84. hallar el numero de electrones?
Answers
Answer:
49
Explanation:
Según la pregunta;
Relación de número atómico a número de neutrones = 7: 5
Debemos tener en cuenta que el número de neutrones = número de masa - número atómico.
Dado que el número total es 84
Sea el número atómico x
Por eso;
7/5 = x / 84 -x
7 (84 -x) = 5x
588 - 7x = 5x
588 = 5x + 7x
588 = 12 veces
x = 588/12
x = 49
Dado que número atómico = número de protones = número de electrones
El número de electrones = 49
You have 12.7 g of sugar in a sugar water solution. The percent by mass of the sugar is
15.8%, how many grams of solution are there?
Answers
Answer: Mass of solution is 80.4 g
Explanation: 15.8 % = 0.158. Mark mass of solution with x
You can make an equation for mass of sugar: 0.158 x = 12.7 g
x = 12.7 g / 0.158

write the conclusion of coin and feather experiment.
Answers
Answer: In a vacuum, the objects fall at the same rate independent of their respective masses. That means coin and feather both reach ground at same time in a vacuum. Larger objects experience more air resistance than smaller objects. Also, the faster an object falls, the more air resistance it encounters.

A. The salinity and temperature of ocean water remain the same as depth increases.
B. The salinity and temperature of ocean water increase as the depth increases.
C. The salinity of ocean water decreases and the temperature of ocean water increases as the depth increases.
D. The salinity of ocean water increases and the temperature of ocean water decreases as the depth increases.
Answers
Answer: D
Explanation:
I would say D, because it makes sense for the temperature to decrease with depth because less sunlight means less heat. I'm not sure about the salinity 100% but I think it increases.
