0.986 moles of CaO are formed when 98.60 g of decomposes.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others.
Number of moles of CaCO3 =
Number of moles of CaCO3 =
= 0.986 moles
Reaction:
→
Since the reaction is 1:1:1.
So 0.986 moles of CaO are formed.

Answer:
Atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.
Explanation:
Answer:
The field lines go out of Earth near Antarctica, enter Earth in northern Canada, and are not aligned with the geographic poles.
Explanation:
The two poles North pole and South pole of the earth are distinct from the magnetic north pole and south pole of the earth. The magnetic north pole is the point from where the magnetic field of the Earth points downwards in the vertical direction. There is a gradual change in the magnetic poles with the passing of the time. The magnetic fields have an extension from the interior of the Earth to the outer space.

Answer:
acceleration: 5 mi/h/s north
Explanation:
A quantity can be either vector quantity or scalar quantity, a vector quantity is a quantity with both magnitude and direction while a scalar quantity has magnitude only.
Examples of vector quantities include; velocity, acceleration, displacement , etc.
Acceleration is the rate of change of an object's velocity per unit of time. It is given by the formula; Velocity/time
Therefore in this case; a = 30 mi/h /6 s
= 5 mi/h/s
Therefore;
Acceleration = 5 mi/h/s
