Why can chlorine molecules have three different values of mass number?
Wiki User
∙ 15y ago
Chlorine atom has two isotopes - with Mass Number = 35 and 37. One Chlorine molecule can be any of three combinations - 35+35 = 70, 37+37=74 and 35+37 = 72.

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 moles are in 47g of chlorine gas?
4.005
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.
What is the difference between molecular weight in amu and molecular weight in grams?
The only difference is the name of the unit; the numerical values are the same. However, the value in amu is the mass of a single molecule, while the molecular weight in grams is the mass of Avogadro's number of molecules. The mass of Avogadro's number of molecules is called a Gram-mole. The molecular weight of , say, Hydrogen H2 is 2 amu. A gram mole of this would be 2 grams. The molecular weight in grams is the weight of this molecule in real grams and is an extremely small value.
What is the values represents the number of carbon atoms in one mole of methane?
elements and compounds.atom or atomic structure
What are the properties of cis molecules?
Cis molecules have the properties of all substances but of course the values are different for cis and trans.
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.
If a binary number needs to represent 16 different values how long must the number be in bits?
4 bits
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
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 do z mean in a algebra problem?
It is simply a variable - it represents a number which can take different values.
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.
What has an atomic radius of 099?
It is a difference between the empirical and the calculated atomic radius of an element; also all the values are only approximates. The empirical atomic radius of sulphur, phosphorous and chlorine is 100 pm. The calculated atomic radius of phosphorous is 98 pm.
