How many molecules of LiCl are in a 127.17 g sample?
To find the number of molecules of LiCl in a 127.17 g sample, you first need to convert the mass of LiCl to moles using its molar mass. Then, use Avogadro's number (6.022 x 10^23) to convert moles to molecules. Calculate the number of molecules of LiCl in the sample using these values.
How many moles are in 47g of chlorine gas?
4.005
Why is hydrogen chloride polar?
Hydrogen chloride is non polar because in molecules such as (hcl) the electron pair of bond is pulled closer to more electroneative chlorine atom.As a result of this the chlorine atom develops a tiny negative charge,where as the hydrogen atom develops a tiny positive charge.The hydrogen chloride molecule has a slight separation of charge within it and describe as a polar molecule
How many of each type should combine lithium and chlorine?
Go to the periodic table and look at the oxidation states for lithium and for chlorine. You will notice that there is only one value for lithium, and several values for chlorine. Therefore, the oxidation state for lithium is going to determine the answer for "how many chlorines." Now look at chlorine. Since the oxidation state for lithium is a positive value, which of the oxidation states for the chlorine would be applicable (remember lithium chloride is an ionic bond)? Identify the appropriate oxidation state for chlorine, and adjust accordingly.
How do isotopes differ and why is the atomic number of elements not a whole number?
Isotopes differ from each other by having different numbers of neutrons but the same number of protons since they are only the same element if they have the same number of protons. Atomic numbers aren't whole because their mass is based of the mass of hydrogen and amu's (atomic mass units) and due to how elements are formed, minute amounts of mass are lost in order to form the nuclear bonds resulting in not whole numbers.
What is the value of the digits in the number 0.303?
The different digits have different values.
Is the mean and median the same?
No, they are both averages but worked out in different ways and give different answers. The mean is the sum of all the values added together and then divided by the number of values there are. The median is found by arranging the values in numerical order and finding the number in the middle.
How many molecules of LiCl are in a 127.17 g sample?
To find the number of molecules of LiCl in a 127.17 g sample, you first need to convert the mass of LiCl to moles using its molar mass. Then, use Avogadro's number (6.022 x 10^23) to convert moles to molecules. Calculate the number of molecules of LiCl in the sample using these values.
If a binary number needs to represent 16 different values how long must the number be in bits?
4 bits
What values represents the number of molecules of CH3CL in 101 grams of the substance?
To find the number of molecules of CH3Cl in 101 grams of the substance, you would first convert 101 grams of CH3Cl to moles using its molar mass. Once you have the moles of CH3Cl, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
Why does a positive number and a negative number cancel each other out?
The range of the numbers from 0 is what additively cancels the different values
What do z mean in a algebra problem?
It is simply a variable - it represents a number which can take different values.
Is the mean and median similar?
The Mean is the average of a given set of values. The Median is the value that has the same number of smaller values than the number of higher values, it is in the middle of them. In a symmetrical distribution the Mean is equal to the Median. In an asymmetrical distribution they have different value.
What is 7.6196875 rounded?
I can see eight different place values to which that number could be rounded. The choice is yours. The answer is different for each one.
A variable is discrete if each of its values is distinctly different from the value that follows it?
and it cannot take on values in between its distinct values. Examples of discrete variables include the number of children in a family, the number of cars in a parking lot, and the number of heads obtained when flipping a coin.
Describe how place value is used to compare decimals?
Align the numbers according their place values. Go from left to right (decreasing place values) until the face values of the numbers are different. Then the number with the larger face value in that place is the larger number.
