<span>Ground water depletion is one of the major problems. The best solution is to conserve water that we are having currently and to recycle those wasted water. water conservation can be done in many ways such as reduce the level of pumping the ground water, avoiding the use of chemicals, use of natural fertilizers, rain water saving, pumping water to the tanks from stored rain water in the ground, way of handling the water consuming jobs.</span>
2C₆H₁₄+19O₂⇒14H₂O+12CO₂+energy
You can tell that the energy is on the left side since the reactoin is highly exothermic meaning it releases heat which can also be thought of as energy.
I hope this helps
Greater than 23mcg/dl is considered a high level of morning cortisol.
Normally, cortisol levels rise during the early morning hours and are highest about 7AM. They drop very low in the evening and during the early phase of sleep. If you do not have this daily change (diurnal rhythm) in cortisol levels, you may have overactive adrenal glands. This condition is called Cushing's syndrome.
a. atoms
Explanation:
Let's take as example carbon and lead. Carbon have an atomic mass of 12 a.m.u while lead have an atomic mass of 207 a.m.u. Value of atomic masses are the same with as the value of molar masses. So carbon have a molar mass of 12 g/mole while lead have a molar mass of 207 g/mol.
Avogadro's number it tell us that in 1 mole of particular substance there are 6.022 × 10²³ particles. Taking in account this, in 12 g of carbon there are 6.022 × 10²³ carbon atoms and in 207 g of lead there are 6.022 × 10²³ lead atoms atoms.
The atomic mass of any two elements contain the same number of atoms.
