How is ammonia is a base give me answer because it does not contain hydroxyl ions as it does not contain hydroxyl ions?

Ammonia is a base because, when it is dissolved in water it forms an hydroxide ion, which is highly unstable and when performed with test will show all results for basic nature.

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
