What are gravitational forces?
Answers
Answer:
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects
The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe!
Gravitational force is the force that attracts to objects with mass. ... This forces tries to pull masses together, that is why attractive in nature. For example: When ball is thrown upwards it always come downwards after a certain height because the ball is pulled or attracted by the Earth's gravitation la force.

The reaction represented by this graph is an exothermic reaction. According to the graph, which statement is true? Reactants have more energy than products. Products have more energy than reactants. Reactants and products have the same amount of energy.
Answers
Answer:
Reactants have more energy than products
Explanation:
Generally, in an exothermic reaction heat is released. In other words, energy is released. So you start with reactants which have a set amount of stored chemical energy, and you lose some in the reaction. Since energy is 'leaving', the stored chemical energy in the products is less than what we started with in the reactants. When given a graph, you can tell this is true because going from left to right, the line representing the stored chemical energy will start at a higher level than where it ends.
The true statement about an exothermic reaction is that reactants have more energy than products.
What is an exothermic reaction?An exothermic reaction is one in which the energy of reactants is greater than that of products. As such, energy is given off during the reaction in form of heat.
Thus, the true statement about an exothermic reaction is that reactants have more energy than products.

Why does oxygen have a higher electronegativity compared to chlorine?
Answers
Answer:
The electronegativity of fluorine compare to the electronegativity of oxygen and chlorine as below
Explanation:
Fluorine has the highest electronegativity than oxygen, and chlorine.
Explanation
Generally the electronegativity increase across the period ( from the left to the right) and decreases down the group.
Both oxygen and fluorine are in period 2 in periodic table. since fluorine is on fur right side as compared to oxygen , fluorine has higher electronegativity than oxygen.
On the other side Fluorine and chlorine are in the same group in periodic table. fluorine is at the top of the group while chlorine is at the bottom therefore fluorine has higher electronegativity than chlorine.
