Answer:
Tha valency of Oxygen is 2 because it need two atom of hydrogen to form water.
The answer is <span>C. 49 m/s
The kinetic equation is:
v2 = v1 + a * t
v1 - initial velocity
v2 - final velocity
a - gravitational acceleration
t - time
We know:
v2 = ?
v1 = 0 (in free fall
a = 9.8 m/s
t = 5
</span>v2 = v1 + a * t
v2 = 0 + 9.8 * 5
v2 = 0 + 49
v2 = 49 m/s
True
Explanation:
A base is a substance that is often used as the chemical opposite of an acid.
Both behaves in opposite way to one another.
They can be said to complementary or conjugate chemicals.
- According to Bronsted-Lowry theory, an acid is a proton donor and a base is a proton acceptor.
- The lewis theory states that an acid is an electron pair acceptor while a base is an electron pair donor.
