______ is a way to describe matter with numbers and units.
Answers
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.

When a comet enters the solar system, it curves toward the sun. Which statement describes why the sun does not move when a comet is nearby?
Answers
Answer:
Explanation:
When a comet enters the solar system it curves towards the Sun due to the Sun's gravitational pull. Every celestial object in the universe has a gravitational pull whose force is dependent on the object's mass. The larger the object is the more gravitational pull it will have. The Sun is the largest object in our Solar system and therefore has the most gravitational pull. This is why the comet curves toward the Sun, but the opposite does not happen because the comet's gravitational pull is not strong enough to pull the Sun.
how does the law of conservation of mass applies to all chemical reactions?
Answers
Answer:
the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
Explanation:
The law of conservation is Matter cannot be created or destroyed in chemical reactions so it means exactly that
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
Answers
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.

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
Answers
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.

a) 0.047
b) 1
c) 2
d)21.2
Answers
Answer:
0.047
Explanation:
Data : 5g , Na2CO3
Formula:
Molecular mass of Na2Co3 = no.of atomic mass x no. of atom
moles = mass÷ molecular mass
molecular mass = 2(23)+1(12)+3(16)
=106amu
moles = 5÷106
= 0.047 Ans:
What is the freezing point of solution that has 185.25 grams of Ca(OH)2 (formula mass = 74.1) dissolved in 2,500 grams of water at standard pressure?
Answers
Answer:
The freezing point depression ∆T = KF·m where KF is the molal freezing point depression constant and m is the molality of the solute. Rearrangement gives: mol solute = (m) x (kg solvent) where kg of solvent is the mass of the solvent (lauric acid) in the mixture. This gives the moles of the solute.

What is the ratio of the effusion rate of the helium to methane? (round to hundreds)
Answers
Answer:
2.00
Explanation:
From Graham's law; the rate of effusion is inversely proportional to the square root of the relative molecular mass.
Let the rate of effusion of Helium be R1
Let the rate of effusion of Methane be R2
Let the molecular mass of Helium be M1
Let the molecular mass of Methane be M2
Hence;
R1/R2 = √M2/M1
R1/R2 = √16.0294/4.0026
R1/R2 = 2.00
