Answer:
2Al + 3Ni(SO4) -------> 1Al2(SO4)3 + 2Ni
Explanation:
Buffers - mixtures of conjugate acid and conjugate base at ±1 pH unit from pH = pKa. Resistant to changes in pH in response to small additions of H+ or OH-. ... Polyprotic acids - dissociation of each H+ can be treated separately if the pKa values are different
Answer:
Imo : Gas particles are in constant, random motion. The volume of gas particles is negligible in comparison to the volume of the container. There are no attractive forces between gas particles.
The Eukaryotic cell has a nucleus
Answer:
100N
Explanation:
Given parameters:
Mass of the bowling ball = 20kg
Acceleration = 5m/s²
Unknown:
Amount of force applied = ?
Solution:
To solve this problem, we apply newton's second law of motion.
Force = mass x acceleration
Now insert the parameters and solve;
Force = 20 x 5 = 100N
