Making observations is the first step in the scientific method. Why don't scientists stop with the first step when creating an experiment? *14 pointsA. Scientists don't stop with the first step of their experiment because they don't think that just using their observations is a very good place to start to prove their hypothesis.B. Scientists don't stop with the first step of their experiment because they not only want to observe but they want to test their observations to be sure they are correct.C. Scientists don't stop with the first step of their experiment because they want other scientists' opinions because they may not trust their own observations.D. Scientists don't stop with the first step of their experiment because they would rather plan and run experiments than just observe the world around them.

Which one of this is endothermic and which one is exothermic?CH2+O2 -> CO2+H2O+Energy
CaCo+Energy -> CaCo+CO2

Answers

The first one is exothermic because energy is a reactant, the second formula is endothermic

The reaction between zinc and hydrogen chloride produces zinc chloride, hydrogen gas, and heat. If more heat is removed from the reaction, how does the rate of reaction change to counter the action?

Answers

Answer:

The rate of reaction increases to counter the action of removing heat.

Explanation:

  • The reaction between zinc and hydrogen chloride produces zinc chloride, hydrogen gas, and heat.
  • The reaction is exothermic reaction. Heat is produced in the reaction.
  • It means the temperature of system increase when reaction proceeds. When heat is removed from system, it stimulates the reaction to fast to produce more heat.
  • Due to fast reaction rate of reaction increases.

Which of the following describe hybrid atomic orbitals? check all that apply a mixture of all atomic orbitals in an atom a mixture of the valence orbitals in an atom There are as many hybrid orbitals as there are electrons in an atom. There are as many hybrid orbitals as there are valence electrons in an atom. There are as many hybrid orbitals as there are valence orbitals that mix together. have a different shape and a different energy than the atomic orbitals of which they are made have the same shape but a different energy than the atomic orbitals of which they are made

Answers

The hybrid atomic orbitals are formed by the combination of the valence orbitals on an atom. The hybrid orbitals formed have different energy and shape compared to the atomic orbitals that combine to form the hybrid orbitals. Hybrid orbitals help in explaining the shapes of the molecules and other bonding properties.

Therefore the correct answer will be,

b. A mixture of the valence orbitals in an atom

e. There are as many hybrid orbitals as there are valence orbitals that mix together.

f. Hybrid orbitals have a different shape and different energy than the atomic orbitals of which they are made

What is a valence electron and why are they so important to a chemist?

Answers

Valence electrons are the electrons that reside in an atom's outermost shell. The role of valence electrons in determining an atom's reaction makes them crucial. You can count how many electrons are at the highest energy level by writing an electron configuration.

How do the valence electrons function?

The electrons in an atom's outermost shell are called valence electrons. … Because the electrons in the outermost shells of two atoms are the first to come into contact with one another and are the ones that control how an atom will react in a chemical reaction, when two atoms interact.

The outer-shell electrons of an atom are known as valence electrons. The valence electrons in an atom control its reactivity.

They are important because they are the electrons that help the atom to bond with another atom. They are in the outer most shell. ☺️
