In a water molecule, which atom has the strongest attraction for shared electrons? hydrogen oxygen hydroxide ion both atoms attract electrons with equal strength neither atom attracts the electrons

The correct answer is oxygen.

Explanation:

An atom refers to the smallest constituent of an element, which holds all the chemical characteristics of that element. Each element exhibits a familiar electronegativity, that is, a measurement of their affinity towards electrons. In the molecule of water, the element oxygen is very electronegative as it robustly fascinates electrons from other atoms. On the other hand, hydrogen has low electronegativity and therefore, attracts electrons weakly.

the maximum mass of nh3 is nh3 in grams

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
