Answer:
c.mass and distance
Explanation:
gravitation=mass/distance ²
If one starts with 0.020 g of Mg, 0.0008 moles of H2 would be made if the reaction is complete.
Going by the balanced equation of reaction in the image, 1 mole of Mg will produce 1 mole of H2 in a complete reaction.
If 0.020 g of Mg is started with:
mole of Mg = mass/molar mass
= 0.020/24.3
= 0.0008 moles
Since the mole of Mg to H2 is 1:1, thus, 0.0008 moles of H2 will also be made from the reaction.

Answer:
Wall, cup, mug, plastic spoon
Explanation:
Because all of those are glass and it is important to us to make sure that if you are touching this brle careful
Answer:
Let's start by using the definition of acceleration. Acceleration is defined as the change in velocity over the change in time. In equation, that would be Δvelocity/Δtime. Based on the axes of the given graph, it shows the trend of position over time. So, the slope of the line and the curve shows the change of position over change of time, Δdistance/Δtime. In physics, this is the definition of speed or velocity. So, Maia is incorrect. Both curves show the speed or velocity of the object, and not acceleration. If the graph used a y-axis of velocity instead of position, then only at that instance, would be Maia be correct.
The difference between the two is, the straight line shows constant velocity while the curve line shows changing velocity.
