Answer:Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as "mudstones." ... "Fissile" means that the rock readily splits into thin pieces along the laminations.

Answer:
Number of moles is defined as the ratio of given mass in g to the molar mass.The mathematical expression is given as:
Number of moles =Number of moles of compound = 12.7 moles (given)As, 1 mole of any compound is equal to particles.
where, is Avogadro number. Formula for calculating particles is given by:
where, N = number of particles, n = number of moles and is Avogadro number.
Put the values,= or Hence, number of particles of the compound is equal to
Explanation:
Answer:
C) It will accelerate.
Explanation:
According to Newton’s second law of motion, when an object is acted on by an unbalanced force, it will accelerate.
An unbalanced force will change the speed or direction (or both) of an object. A change in speed and/or direction is acceleration.
A) is wrong. The object will stop moving only if there is a balanced force in the opposite direction.
B) is wrong. The object will decrease speed only if the unbalanced force has a component opposite to the direction of motion.
d) is wrong. The object will increase speed only if the unbalanced force has a component in the direction of motion.
Answer:
Everything is composed of atoms! which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass.

Answer:
have stars that might appear to wobble
often have one star that is brighter than the other
Explanation:
A binary star system is a star system made up of mostly two stars that moves round their common fixed center.
The two orbiting stars are gravitationally bonded to one another and they move round each other.
Most binary stars might appear wobble. One of the stars often appears brighter than the other.
