Answers
The two subspecialty of astronomy are astrophysics and planetaryscience. Correct option is D.
Astronomy is the scientific study of celestial objects, such as stars, planets, galaxies, and other phenomena in the universe. Within the field of astronomy, there are several subspecialties that focus on specific aspects of celestial objects and phenomena.
Astrophysics: Astrophysics is a branch of astronomy that deals with the physical properties, behavior, and interactions of celestial objects. It involves the application of physics principles and theories to understand the nature of stars, galaxies, black holes, and other cosmic phenomena. Astrophysicists study the processes that govern the birth, evolution, and death of stars, as well as the formation and dynamics of galaxies.
Planetary Science: Planetary science is another subspecialty of astronomy that focuses on the study of planets, moons, asteroids, comets, and other objects within our solar system and beyond. Planetary scientists investigate the geology, atmospheres, surfaces, and composition of planets and their satellites. They also study the origin and evolution of planets, the potential for habitability, and the possibility of past or present life on other celestial bodies.
Both astrophysics and planetary science are essential in expanding our understanding of the cosmos. Astrophysics helps us comprehend the fundamental principles and processes that govern the entire universe, while planetary science provides insights into the unique characteristics and properties of the planets and bodies within our solar system, shedding light on potential habitability and the origins of life.

Any substance that tastes unpleasant in water solution, turns blue litmus paper red, reacts with some metals to release hydrogen, combines with bases to create salts, and stimulates chemical processes is considered an acid. Here among the given options, NaOH is a base. The correct option is D.
Any hydrogen-containing material that has the ability to donate a proton (hydrogen ion) to another chemical is considered an acid. A base is a molecule or ion that can take up an acid's hydrogen ion. Typically, sour tastes help to identify acidic chemicals.
An acid is not NaOH. It is categorized as a base, more specifically a strong base, because it can receive protons from any proton donor and completely dissociates into sodium and hydroxide ions in an aqueous form.
Thus the correct option is D.

Answer:
150ml .........60 minute
x ........... 1 minute
x = 150ml× 1 minute / 60 minute
x = 2.5ml
Explanation:
it is known that the client receives 150ml of the solution for over an hour.convert the hour into minutes,then we do not know how much liquid a client receives in a minute. we cross multiple the values to get the value in ml. for every one minute the client receives 2.5ml of the fluid.

In a chemical change, the molecules in the reactants interact to form new substances. In a physical change, like a state change or dissolving, no new substance is formed.

Final answer:
Molecules move to the location of a chemical change due to the process of diffusion. In this physical phenomenon, molecules move from an area of high concentration to an area of lower concentration. This diffusion leads to interaction between reactant molecules causing the chemical change.
Explanation:
The movement of molecules to the location of a chemical change is a fundamental concept in Chemistry. In a chemical reaction, molecules move due to a physical phenomenon known as diffusion. Diffusion is the process by which molecules of a substance move from an area of high concentration to an area of lower concentration. For example, if you open a perfume bottle at one end of a room, eventually the perfume molecules will spread throughout the room. These perfume molecules move to areas of lower concentration via diffusion. In the context of a chemical reaction, the reactant molecules diffuse to interact with each other, leading to the chemical change or reaction.

Answer:
C.) condensing steam
Explanation:
Exothermic reactions are chemical reaction which energy is released to the environment in the form of heat . The overall energy of the reactant is greater than the energy of the product. The higher in energy of the reactant causes a release of heat to the environment. In exothermic reactions, enthalpy change is usually negative and is accompanied by the loss of energy in the form of heat or light.
Condensation is the change of water vapor to liquid . The conversion is an exothermic reaction as energy is release to the environment in the form of heat. The water vapor molecules has higher energy than liquid. The changes of water vapor to liquid causes a loss in energy of the water vapor. As the water vapor loss more energy, heat is been release to the surrounding.
All other reaction are endothermic in which heat is absorb from the environment except for condensation of steam.
The event that is an example of an exothermic reaction is condensing steam. The answer is letter C. An exothermic reaction is one in which there is a release of heat during the reaction. Dissolving sugar in water, melting ice and dissolving ammonium nitrate in water are all examples of an endothermic reaction.
