Speed is the rate at which something goes, and velocity is the average acceleration, which means a car can go slow for a bit, and fast for a bit, and have a velocity of medium. Also, speed is much easier to measure.
Answer:
The answer is 1722 e⁻
Explanation:
Let's make a rule of three:
9.708×10⁻³¹ kg is the mass of 1 e⁻
1.672 ×10⁻²⁷ kg (which is 1 p⁺), how many e⁻ does it contain.?
1.672 ×10⁻²⁷ kg / 9.708×10⁻³¹ kg
The answer is 1722 e⁻
The Velocity of a Wave<span>. If the crest of a slinky </span>wave<span> moves a distance of 20 meters in 10 seconds, then the speed of the ocean </span>wave<span> is 2 m/s. ... For a given </span>velocity<span>, if you increase the frequency, the wavelength </span>will<span> be shortened.</span>
Since it has 4 electrons, it needs only 4 more to be stable. Therefore, it would share electrons, which is a covalent bond.
Answer: Covalent bond
Molar mass of SnO_2:-
1 mol of SnO_2 produces 2mol of water
- 0.5mol of SnO_2 will produce 0.5(2)=1mol of water
