Answer:
Explanation:
The equation for this chemical reaction is:
2Ca + O2 -> 2CaO
So 2 moles of Ca react with 1 mole of O2 to form 2 moles of CaO.
Given 3.9 moles of Ca and 2.35 moles of O2,
Ca is the greater reactant as it will be used up.
O2 is the reactant in excess and there will be 2.35 - 3.9/2 = 0.4 moles left.
As mass of 1 mole of O2 is 32g, 0.4 moles of O2 = 0.4 * 32 = 12.8g
Moles of CaO formed = moles of Ca = 3.9
As mass of 1 mole of O2 is 56g, 3.9 moles of CaO = 3.9 * 56 = 218.4g of CaO
Answer: True
Explanation:
Plato did indeed believe that human souls/ minds could survive the death of the body because he believed that they were separate entities. He offered evidence of this in a dialogue titled the ''Phaedo''.
Here he made a series of arguments that he believed showed proof that the soul was a separate entity. One such proof was that the soul was capable of engaging in pure thought while the body did something else. He concluded that the soul was immortal and would exist after death.

The statements 'the gravity of the sun and moon work against each other' and 'smaller than normal range of highs and low tides' are TRUE about neap tides. It is influenced by gravity.
<h3>What are neap tides?</h3>
A neap tide is a period of time in which moderate tides can be observed on the water body (ocean).
Neap tides occur when the gravity of the sun and the moon work faced each other (they are at a right angle to each other).
When the moon and the sun are found at a right angle, it impulses to both to pull the water body into distinct directions.
