Speed is the time rate at which Sue covers the distance. It is derived by dividing the total distance covered by the total time taken to cover the distance . Usually SI unit for speed is km/h or mph or m/s.
Explanation:
Speed is also referred to as velocity- so the two are synonymous.
Acceleration is the rate at which speed is increasing. It is usually given by SI unit m/s². The opposite of acceleration is deceleration which is the rate at which speed is decreasing.
Distance is the measurement, in meters of kilometers or miles or yards..etc, that has been covered from one point to another.

NaCl - inorganic
Phenol - organic
C2H6 - organic
Ca3(PO4)2 - inorganic
CH2O - Organic
MgCO3 - Organic
Basically, if it has Carbon (other than a few) it is organic.
First step: calculate the number of moles of sodium reacted
moles=mass/molar mass
31.5g/23g/mol =1.37moles
from the reaction above the reacting ratio of Na to H2 is 2:1 therefore moles of H2 is 1.37/2=0.685
At STP 1 mole = 22.4L what about 0.685 moles
22.4 x0.685=15.344L
Answer:
B. City B
Explanation:
From the weather chart, you can see that rain is indicated by the dot(.) sign. One dot means light rain and two dots mean steady light rain. The circle shading will show how much cloud in the city, ranging from no cloud(white circle), half covered (half black circle) and completely covered(black circle).
City A has neither cloud nor rain.
City B is completely covered by cloud and have steady light rain.
City C is half-covered with cloud, without rain.
