The location of earth in the solar system is found between Venus and Mars.
A solar system is the gravitational bound system comprising the sun and the objects aligned in the orbit revolving around the sun. The foundation of the solar system is mediated billions of years ago with the huge interstellar cloud collapse.
The planets are present in the orbit bounded by the gravitational force of the sun and revolve around it. Earth is the planet that is said to have only one having the five elements that support life namely. fire, air, water, soil, and space.
The solar system is comprised of 9 planets with the nearest to the sun being mercury, and the farthest being Pluto. Earth is arranged as the third planet from the distance from the sun and is located between Venus and Mars.

Answer:
Ionic Bond
Explanation:
Ionic bonding occurs when there is a significant difference in electronegativity between atoms, resulting in the transfer of electrons. In the case of magnesium (Mg) and oxygen (O), magnesium, with a lower electronegativity, donates two electrons to oxygen, which has a higher electronegativity. This leads to the formation of Mg²⁺ cations and O²⁻ anions. The resulting electrostatic attraction between these oppositely charged ions forms an ionic bond, resulting in the creation of magnesium oxide (MgO), a compound with a crystal lattice structure.
when the substances are chemically reacted the physical properties remain the same
each substance has a unique set of physical properties
no two substances have any of the same properties
The following statements apply:
1. At any given location, the physical properties of a substance do not change.
2. Each substance has a unique set of physical properties.
Each substance usually has some characteristics that are peculiar to it and these characteristics can be used to identify them and separate them from other materials. Change of location does not affect the properties of substances, thus, the properties of oxygen that is found in America is the same as the one that is found in Nigeria.
Respuesta:
2 m
Explicación:
Paso 1: Información provista
Paso 2: Calcular la concentración de la solución final
Queremos perparar una concentración diluida a partir de una concentrada. Podemos calcular la concentración de la solución diluida usando la regla de dilución.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁ / V₂
C₂ = 4 m × 100 mL / 200 mL = 2 m
Trail B will have a lower activation energy than trail A because in this trial the scientist added a catalyst.
A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process.
A catalyst is a substance that speeds up a chemical reaction or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction.
Catalysts slow down reaction rates which will in turn mean a loweractivation.
Hence, trail B will have a lower activation energy than trail A because in this trial the scientist added a catalyst.

Answer:
It will have a lower activation energy than Trial A.
Explanation:
Trail B will have a lower activation energy than trail A because in this trial the scientist adds a catalyst. Catalysts slow down reaction rates which will in turn mean a lower activation.
