Answer:
(B) the energy required to break apart one mole of an ionic compound into its gaseous ions
Explanation:
Lattice energy is the energy that would be obtained from the formation of an ionic compound from its gaseous ions. Therefore, the reverse process that responds the question would be the energy required to break apart an ionic compound and convert its component atoms into gaseous ions.
Lattice energy provides a measure of the stability of an ionic compound. When the ions bind to form the crystalline structure, heat (energy) is released. To break the ionic compound into the ions that form it, it is necessary to provide an energy equal to that released when formed, i.e. the lattice energy.
Answer is: Check for the presence of alpha, beta, and gamma particles.
1) Alpha particle is nucleus of a helium-4 atom, which is made of two protons and two neutrons.
Alpha decay is radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and transforms into an atom with an atomic number that is reduced by two and mass number that is reduced by four.
2) Beta decay is radioactive decay in which a beta ray and a neutrino are emitted from an atomic nucleus.
There are two types of beta decay: beta minus and beta plus.
3) During gamma emission the nucleus emits radiation without changing its composition.
Muscle tissue
Explanation: Muscle tissue is a soft tissue that makes up most of the tissues in the muscles of the human muscular system. It is the only type of tissue that has cells with the ability to contract. Skeletal muscle tissue is attached to bones by tendons.
Answer:
3.75 moles
Explanation:
The chemical equation is 2CH₃OH + 3O₂ -> 2CO₂ + 4H₂O
2 moles of CH₃OH are burned by 3 moles of O₂
For 2.5 moles of CH₃OH are burned by x moles of O₂
Let's solve for x :
2*x=2.5*3 => 2*x=7.5 => x=3.75 moles of O₂ are needed to burn 2.5 moles of CH₃OH
So basically Positive reinforcement is when you give someone something for showing a good behavior, and a negative reinforcement is giving someone a consequence for showing bad behavior.
Hope this helps:)
