Answer:
84.8%
Explanation:
Step 1: Given data
Bob measured out 1.60 g of Na. He forms NaCl according to the following equation.
Na + 1/2 Cl₂ ⇒ NaCl
According to this equation, he calculates that 1.60 g of sodium should produce 4.07 g of NaCl, which is the theoretical yield. However, he carries out the experiment and only makes 3.45 g of NaCl, which is the real yield.
Step 2: Calculate the percent yield.
We will use the following expression.
%yield = real yield / theoretical yield × 100%
%yield = 3.45 g / 4.07 g × 100% = 84.8%
Energy storage is the capture of energy produced at one time for use at a later time. A device that stores energy is generally called an accumulator or battery.
Answer:
B. Pluto's orbit is not clear of other objects
Explanation:
Pluto is a dwarf planet and considered as ninth planet of the solar system.
A large body whose orbit do not clear the neighbourhood is classified as a dwarf planet. The gravity of Neptune limit the orbit of Pluto and shares its orbital neighbourhood with many Kuiper belt objects.
Hence, the correct answer is "B. Pluto's orbit is not clear of other objects".
Electrons have a mass of 1/1836

An experiment is used to establish a cause and effect relationship.
<h3>What is an experiment?</h3>
The whole aim of an experiment is to be able to deduce the effect of one variable on another. This is why we often say that an experiment is used to establish a cause and effect relationship.
Now the independent variable is the variable that is being manipulated in the experiment. In this case, the independent variable is the height of the track.
As the independent variable is manipulated, the variable whose value changes likewise is called the dependent variable. In this case, the dependent variable is the speed of the car.
