Answer:
To plot a graph, you put the independent variable on the y-axis and the dependent on the x-axis. This might sound really hard, but it's not.
A dependent variable is something that is changed by other factors. For example, in this question, the temperature is dependent on the time. You can't change time by temperature, it's impossible. But you CAN change temperature by the more time that goes by. This makes Time independent and Temperature Independent.
You write the graph so that Time (1-10) goes up the side (the y-axis), starting from the bottom left (this point is called the origin). Then you write the Temperature on the bottom, from left to right. The numbers you are given have to have the same amount of points (the little squares you see) in between them, and you have to be able to fit all of the numbers on the graph.
The last step is to plot the points on the graph so they match up. If the time is 1, then you go to where the time says one and move over to the right to where it is the correct temperature. That is where you put your point. You keep doing this until you have all the points plotted and you can connect the dots.
Explanation:
The electronic configuration of a chloride ion in a compound of BeCl2 is
2.8.8
This is because chlorine atom which electronic configuration 2.8.7 gain one electron form Be to form chloride ion with 2.8.8 electronic configuration. BeCl2 is an ionic bond which is formed by a metal and a non metal.metal (Be)loses electron and become positively charged while non metal (Cl2) gain electron and become negative charged.
Explanation:
Cellulosic ethanol is ethanol (ethyl alcohol) produced from cellulose (the stringy fiber of a plant) rather than from the plant's seeds or fruit. It can be produced from grasses, wood, algae, or other plants. It is generally discussed for use as a biofuel.
Answer:
<h2>3920 Joules</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 40 × 9.8 × 10
We have the final answer as
<h3>3920 J</h3>
