What is the opposite reaction pair to gravity?
The opposite reaction pair to gravity is the normal force.
What is mirror nuclie?
There is no specific scientific term known as "mirror nuclie." It is possible you may be referring to "mirror nuclei," which are pairs of atomic nuclei that have the same number of protons and neutrons, but in opposite configurations. These mirror nuclei display symmetry in certain nuclear properties.
Each force in an action-reaction pair of forces is equal in what?
Each force in an action-reaction pair of forces is equal in magnitude but opposite in direction. This is known as Newton's third law of motion.
What is the word for a pair of forces that are equal and opposite?
The term for a pair of forces that are equal in magnitude and opposite in direction is "action-reaction pair" according to Newton's third law of motion.
What type of nuclear energy powers the sun?
Nuclear fusion in the sun works by fusion of hydrogen nuclei, ie protons, into helium nuclei. There are three stages: 1. two protons combine to form a proton-neutron pair, a positron, and a neutrino. 2.a proton-neutron pair combines with another proton to form a doubleproton-neutron triplet and a gamma ray. 3. two doubleproton-neutron triplets combine to form a doubleproton-doubleneutron particle (ie a helium nucleus) and two more protons. The energy releases of these stages are as follows: In the Sun, with a 10 million K core, hydrogen fuses to form helium in the proton-proton chain reaction: : 41H → 22H + 2e+ + 2νe (4.0 MeV + 1.0 MeV) : 21H + 22H → 23He + 2γ (5.5 MeV) : 23He → 4He + 21H (12.9 MeV) These reactions result in the overall reaction: : 41H → 4He + 2e+ + 2γ + 2νe (26.7 MeV) where e+ is a positron, γ is a gamma ray photon, νe is a neutrino, and H and He are isotopes of hydrogen and helium, respectively. The energy released by this reaction is in millions of electron volts, which is actually only a tiny amount of energy. However enormous numbers of these reactions occur constantly, producing all the energy necessary to sustain the star's radiation output. Thus the overall energy production of a helium nucleus releases 26.7 MeV. (1MeV = 1.6 x 10-13 Joules) This is partly gamma energy and partly kinetic energy of the particles formed. You can follow this process with the diagram attached as a link below
When two hydrogen nuclei combine to form one helium nucleus nuclear fusion has taken place.?
Yes, this is nuclear fusion.
Which pair of substances might be involved in an oxidation-reduction reaction that would result in the formation of ions?
One possible pair of substances that could be involved in an oxidation-reduction reaction to form ions is magnesium and oxygen. In this reaction, magnesium would undergo oxidation to form Mg2+ ions, while oxygen would undergo reduction to form O2- ions.
Do stars give off light as a part of a nuclear fusion reaction in which helium atoms are split into hydrogen atoms?
No. In a fusion reaction, a heavier element is made of a lighter pair by "gluing" them together in a fusion reaction. When we split an atom, that's called atom splitting, or sometimes fission, not fusion. They are opposites. Stars give off light, but the primary fuel in their fusion engines is hydrogen, which they convert into helium. As the hydrogen burns out, the star begins making helium into carbon.
Where do the neutrons come from when hydrogen turns into helium in nuclear fusion?
In fusion engines we call stars, protons, which are hydrogen nuclei, are forced together and fused to create helium. This happens in early stellar life with the small- to medium-sized stars. When the protons are forced together, the first step involves fusing a pair of protons together with the weak interaction or weak nuclear force mediating the change of a proton into a neutron. Deuterium, or heavy hydrogen, is created. When deuterium reacts with a proton and the pair of particles are fused, a helium-3 nucleus is formed. From there, the reaction possibilities increase and we view what could occur along branches. This is the proton-proton chain reaction that is the basic process in stellar nucleosynthesis. The key to understanding these reactions is the knowledge of the ability of a proton to transform into a neutron through mediation by the weak nuclear force.
Why aromatic amine not undergo mannich base reaction?
Aromatic amines do not undergo the Mannich base reaction because they lack a sufficiently acidic hydrogen atom attached to the nitrogen atom. In the Mannich reaction, the amine hydrogen needs to be acidic to facilitate the formation of an enolate ion, which then reacts with an electrophile. Aromatic amines do not have this acidic hydrogen atom, so they cannot undergo the Mannich reaction.
What is the opposite reaction pair to gravity?
The opposite reaction pair to gravity is the normal force.
When the atomic nuclei of a pair of aluminium nuclei are fused the element produced is?
You cannot fuse two lithium atoms, the immediate product of high energy collisions of lithium nuclei are alpha particle showers and some neutrons.Li6 + Li6 --> He4 + He4 + He4Li6 + Li7 --> He4 + He4 + He4 + nLi7 + Li7 --> He4 + He4 + He4 + 2n
What is nuclied?
Mirror nuclei is a pair of atomic nuclei. Each would be transformed into the other by changing all its neutrons into protons, and vice versa.
Which pair of terms best describes the type of change that occurred in the reaction hydrogen plus oxygen leads to water plus energy?
Chemical change and exothermic. In this reaction, hydrogen and oxygen undergo a chemical change to form water, releasing energy in the form of heat and light.
A chemical reaction occurs between sodium hydroxide and hydrogen chloride?
When sodium hydroxide and hydrogen chloride react, they undergo a neutralization reaction to form sodium chloride (table salt) and water. This reaction is highly exothermic, releasing heat in the process. Sodium hydroxide is a strong base, while hydrogen chloride is a strong acid, making them an ideal pair for a neutralization reaction.
What is a lone pair?
A lone pair is a pair of electrons in an atom that is not involved in bonding with other atoms. It is often represented as a pair of dots in Lewis structures and can influence the shape and reactivity of molecules.
