1. Schrodinger's Cat- A many world's theory that describes quantum coherence and phenomenon.
2. Newton's 1st Law- says that objects in rest will stay in rest and objects in motion will stay in motion. The most important lesson here is that an object in rest may not be in rest position.
3. Ohms law- says the current passing through an area is directly proportional to the voltage

Write the formula equation for the reaction between hydroiodic acid and beryllium hydroxide

Aleksandr-060686 [28]

The formula equation for the reaction between hydroiodic acid and beryllium hydroxide is as below

Be(OH)2 + 2 HI = BeI2 + 2H2O

Formula of hydroiodic is = HI
formula of beryllium hydroxide = Be(OH)2

1 mole of Be(OH)2 react with 2 mole of HI to form 1 mole of BeI2 and 2 mole of H2O

Different between chlorine and chloride

ZanzabumX [31]

Chlorine: The greenish-yellow, highly reactive and diatomic gas that is almost never found free in nature by itself. Most Chlorine is commercially produced and is most widely known for being used within compounds to purify water and create cleaning products.

Chloride: The negatively charged ionic form of Chlorine. Since Chlorine is found deep within the Earth's crust, and is extremely reactive, the only way it can be found in nature is when it reacts with other chemicals and creates compounds. Chloride is what is created when Chlorine gains an electron and combines with other elements. Chloride is found abundantly in nature and is most commonly known for forming neutral salts such as sodium chloride (table salt), potassium chloride, and calcium chloride.

Graphing is an important procedure used by scientist to display the data that is collected during a controlled experiment. There

astraxan [27]

Bar graph or bar chart displays data graphically using bars

The correct values are;

1. The independent variable is the month of the year

2. The dependent variable is the number of deer

3. The title is: The number of deer counted per month

The reason the above values are correct are as follows:

In a tabular form is given as follows;

$\begin{array}{|c|cc|}Month&&\# \ of \ deer \\Sept&&38\\Oct&&32\\Nov&&26\\Dec&&20\\ Jan &&15\\Feb&&12\end{array}\right]$

A. Please find attached the required bar graph (chart) created with a desktop application

1. In an investigation to assign the cause of an effect is the cause of an effect, the independent variable is the causal variable responsible for the observed effect, and it is not affected by the effect. It is the variable that is not measured

In the given data, the month of the year is not affected by the number of deer, and it is not counted, to see if there is a change, therefore, the independent variable is the month of the year

2. The dependent variable, is the effect variable that is measured, and it depends on the dependent variable, which is the month

Therefore, the dependent variable is the number of deer

3. An appropriate title is one that captures the information intended to be obtained from the Bar graph

An appropriate title for the bar graph is; The number of deer counted per month
