Answer:
The amount of heat energy that was released by the reaction is 10,460 J.
Explanation:
Sensible heat is that which a body or an object receives or releases and causes its temperature to increase or decrease without affecting its molecular structure and therefore its state.
In other words, sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change). When a body is supplied or absorbed sensible heat, the temperature varies.
The equation that allows calculating heat exchanges is:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case:
c= 4.184 [tex]\frac{J}{g*C}[/tex]m= 100 gΔT= Tfinal - Tinitial= 50 C - 25 C= 25 CReplacing:
Q= 4.184 [tex]\frac{J}{g*C}[/tex] *100 g* 25 C
Solving:
Q=10,460 J
The amount of heat energy that was released by the reaction is 10,460 J.

The period of time needed for a radioisotope to lose one-half of its activity is known as that isotopes
Explanation:
The radioactive scattering technique is called radioactive degradation. For each radioactive isotope, the natural radioactive cycle is special and is determined by a period of time termed a half-life. One half-life was its time needed to experience radioactivity for half of both the radioactive nuclei.

Describe what happens inside a CD
player when you listen to an audio CD.
The thing that happens inside a CD player when you listen to an audio CD is that laser beam turns on and scans along a track with the photocell from the CD's center.
What are semiconductors?The electrical conductivity of a semiconductor material is between that of a conductor, such as metallic copper, and that of an insulator, such as glass.
A small photoelectric cell and a smaller laser beam (called a semiconductor diode laser) are found inside your CD player (an electronic light detector). When you hit play, the disc is rotated at a high speed by an electric motor (not visible in this figure) (up to 500rpm).
The laser beam turns on and scans along a track with the photocell from the CD's center to its edge (in the opposite way to an LP record). As the laser/photocell scans from the center to the periphery of the disc, the motor gradually slows it down (as the track number increases, in other words).
Hence laser beam turns on and scans along a track with the photocell from the CD's center.

______ is a way to describe matter with numbers and units.
Measurement is a way to describe matter with numbers and units.
Measurement is a fundamental process used to describe and quantify various aspects of matter. It involves assigning numerical values to physical quantities and expressing them using appropriate units of measurement.
In scientific and everyday contexts, measurements provide a standardized and consistent way to communicate information about the properties, dimensions, quantities, and characteristics of objects, substances, or phenomena. By using measurements, we can describe the size, length, mass, volume, temperature, time, and many other attributes of matter.
The process of measurement typically involves two components: a numerical value and a unit. The numerical value represents the magnitude or quantity being measured, while the unit provides the reference or scale by which that quantity is expressed. Units help provide meaning, context, and comparability to measurements.
Hence, measurement provides a quantitative and objective way to describe matter, allowing us to understand and interact with the physical world in a systematic and meaningful manner.

What was important about the Hydrogen bright line emission spectrum?
Answer:
The emission spectrum lines are the changes in the quantum energy levels of the single electron in the Hydrogen atom.
Explanation:
Electrons move around the hydrogen atom in electron waves patterns. These waves occur in distinct quantum energy levels.
The change from one quantum energy level to another energy level has a definite energy level change. There is a wave length associated with each change in energy levels. These wave lengths have a color associated with them.
Low energy level changes have long wave lengths associated with them giving red and orange colors.
High energy level changes have short wave lengths associated with them giving blue and violet colors.
Note each atom has a unique emission spectrum associated with the energy levels and electron structure of the atom. Helium was first discovered by looking at its emission spectrum as seen in the sun.

Combustibles fosiles ¿Por qué son inflamables los gases naturales?¿Dónde están los gases naturales?¿Cómo podemos sacar el aceite?¿Dónde está el carbón?¿Es el combustible fósil una fuente no renovable? AYUDAA
Answer:
1) Los gases naturales son inflamables porque el natural contiene metano junto con una pequeña cantidad de otros gases orgánicos, lo que hace que una mezcla de entre 5 y 15% de concentración de gas natural con aire u oxígeno se queme por completo cuando se enciende.
2) El petróleo crudo, que son depósitos de hidrocarburos que se encuentran en depósitos naturales en las formaciones subterráneas de la Tierra, se obtiene perforando un pozo en el yacimiento de petróleo a través del cual se permite que una parte importante del petróleo fluya fuera del yacimiento bajo la presión del yacimiento para recibir procesamiento e instalaciones de almacenamiento en la superficie
3) El carbón se forma cuando se aplica compactación y calor a la turba que proviene de material vegetal muerto enterrado durante un período de varios millones de años.
4) Los combustibles fósiles se consideran una fuente de combustible no renovable porque la velocidad a la que se produce es más rápida que la velocidad a la que se forma.
Una fuente de energía renovable, como la energía eólica, es producida por la naturaleza tan rápido como se consume para generar energía.
Explanation:
Which group in the food chain uses the energy of the sun to create its own food A consumers B predators C producers D prey
Answer:
C producers
Explanation:
All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.
