More water is not always better. For example; cacti only need water about every two weeks, the same with succulent plants. Not every plant needs to be watered every day, or the plant may be overwatered and die.
Explanation:
water near where a river enters the ocean is having a higher density.
coz, ocean water has salt which increases water's density

Answer:
0.0018 moles
Explanation:
Given data:
mass of aspirin= 0.325 g
molar mass of aspirin= 180.1589 g/mol
number of moles=?
Formula:
number of moles= mass in gram/ molar mass (g/mol)
Solution:
now we will put the values in given formula:
number of moles of aspirin= mass of aspirin/ molar mass of aspirin
number of moles= 0.325 g/ 180.1589 g/mol
number of moles = 0.0018 mol
Mole:
Mole is the unit of amount in chemistry. it is SI unit and represented by "mol".
Example;
one mole of hydrogen has a mass of 1.008 g and contain 6.022× 10∧23 atoms.
Answer:
3) 2KOH + H2SO4 → K2SO4 + 2H2O
Explanation:
The balanced chemical equation for the reaction of KOH and H2SO4 is,
→ 2KOH + H2SO4 → K2SO4 + 2H2O
Hence, option (3) is the correct answer.
