A element, because they are identically physically and chemically.
Answer:
The metric system is the preferred system of scientific units for several reasons: The majority of countries in the world employ the metric system of measurement. Because metric units are decimal-based, they are easily converted by moving the decimal point.
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.
Answer: n = m/M = 10 g / 22.99 g/ mol = 0.43 mol
Explanation: M(Na) = 22.99 g/ mol
The answer is C because it's the only that pertains to climate change. The other answers are more about local economy.
