Neutralisation reaction is the reaction between acid and base to form salt and water only
The two products of neutralisation are salt and water
Answer:
Concentration of dissolved salts = 34,038.76 ppm
Explanation:
Given:
Salinity of ocean water = 34
Find:
Concentration of dissolved salts
Computation:
Salinity of ocean water = 34 g/l
1g/l = 1001.14 ppm
Concentration of dissolved salts = 1001.14 ppm x 34
Concentration of dissolved salts = 34,038.76 ppm
A hiker climbs to the top of a mountain at rate of 0.5 m/hr. The speed of hiker is 1.3 x 10⁻⁴ m/s and the velocity of the hiker is 1.3 x 10⁻⁴ m/s west.
Speed is a scalar quantity. It is used to measure the distance traveled in a period of time. It is represented by -
s = d/Δt
where,
s = speed
d = distance
Δt = change in time
Velocity is a vector quantity. It is used to measure the change in position, that is, displacement over the change in time. It is represented by -
v = Δs / Δt
where,
v = velocity
Δs = change in position/displacement
Δt = change in time
The standard unit of velocity and speed both is m/s.
