Answer:
Displacement is the direction from the starting point and the length of a directly line from the starting point to the ending point.
Molar mass glucose : <span>180.1559 g/mol
</span>
number of moles:
n = mass solute / molar mass
n = 225 / 180.1559
n = 1.248 moles
therefore:
Molarity = moles solute / volume
Molarity = 1.248 / 0.825 => <span>1.513 M</span>
Zn(s) +2 HCl(aq) ---> ZnCl2(aq) +H2(g) (products are Zinc chloride and hydrogen gas)
It is known as the Magnetic Field.
Answer:
This question is incomplete
Explanation:
This question is incomplete.
However, when all the required data are available, you can use the formula/steps below
Average speed/velocity (m/s) = distance (in metres) ÷ time (in seconds)
Time (in secs) = distance ÷ average speed/velocity
Kindly note that "blocks" is not a standard unit for distance measurement in science, hence the distance (since its a walking distance) must be in metres (or converted to metres if not in metres).
The distance in the formula is the distance from the hotel to the ice cream shop while the average speed is the distance covered per time as s/he walks to the ice cream shop and back. Hence, the answer gotten from the formula above will have to be multiplied by 2 (in order to get the time taken to walk to the ice cream shop and back) because the formula will only provide answer to one trip (time taken to walk to the shop).
After the multiplication mentioned above, the time in seconds should be converted to minutes by dividing the answer in seconds by 60
