When an isotope undergoes beta decay which of the following does NOT change?
The answer is c., The mass number.Check step 5 below.Let's walk through balancing a nuclear equation involving beta decay. We are going to figure out a balanced equation for thorium-2341. You will need to find the atomic number for thorium (234) and the chemical symbol (Th).2. We know that this is undergoing beta decay, so one of the products will be decaying.3. We now need to set up the equation. We are going to use the followingZ=the atomic number of the product isotopeA=the mass number of the product isotopeX-the chemical symbol of the product isotope4. Let's now set up the equation:5. We will now figure out the mass number (A) of the product. We will do this as follows:234=mass number of thorium0=mass number of beta particle234=A+0234=A6. We will now figure out the atomic number (Z) of the product. We will do this as follows:90=Z+(-1) (complete this by subtracting -1 to each side of the equation)90-(-1)=Z+(-1) - (-1)91=Z7. So far we have this:8. Now, we need to figure out the product element (X). We do this by looking for the element that has an atomic number of 91. This is protactinium (Pa). So, the complete balanced equation will look like this:You have balanced an equation using beta decay.
What do you notice about the number of atoms on each side of a chemical equation?
That the number of atoms on the left side of the equation must be the same number of atoms that are on the right side of the equation.
What is the equation for Yb?
Ytterbium is an element (atomic number 70), not an equation.
If the number of atoms of each element in the products equals the number of atoms of each element in the reactants the equation is .?
In this case, the equation is balanced.
Can the number of moles of a substance be found by looking at a balanced equation?
yes the number of moles is the the number before the substance for example if the equation is balanced and you want to find H2O and it appears like 3H2O in the equation then their are 3 moles of H2O
How do you figure out the difference between 5 times a number and 3 is 12?
You write it as an equation, and then solve the equation.
How does the number of tiles added to each figure relate to the equation?
They fit the equation t = 0 exactly.
What are some strategies for finding the area of a figure drawn on a grid?
Count the number of grid squares which are entirely or almost entirely inside the figure = ACount the number of grid squares which are approximately half (or more) inside = B Estimated area = A + B/2.
What is the number of square units a figure encloses?
For easy figures, you can cut up paper squares and see how many squares it takes to cover the figure. However, this takes work and if the figure is complicated, it's hard to figure out. So there's other tricks you learn to find the area of a figure, depending on what the figure looks like.
What is a six figure grid reference?
A six figure grid reference is a more detailed type of grid reference. Basically you divide the squares into 100 smaller squares then write a three figure easting then a three figure northing all you really have to do is take away the decimal point

What is the equation for finding out how many squares are in a 4 by 4 grid?
4 x 4 = 16For any grid n by n, the number of squares is equal to n2 (or n x n)
What is the formula for figuring roofing square?
a roofing square is 100 sf. There are formulas out there that allow you to use the pitch and outer dimensions of the roof to figure out the number of squares. If not, calculate the square footage and divide by 100 - that's the number of squares you have...
Can you subtract the same number from both sides of an equation?
Yes, it is required to figure out some equations.
What number sentence would you use to figure out what number goes in the empty box above?
you need to provide the equation with the number box for this to be answerable.
The number of solution a quadratic equation has?
A quadratic equation always has 2 solutions.In the instance of perfect squares, however, there will be just one number, which is a double root. Graphically, this is equivalent of the vertex of a parabola just barely touching the x-axis.
How do you figure the variance on a group of numbers?
To figure the variance on a group of numbers, you must first figure out the mean, which is the average of the set. Then, substract the mean from each number in the set. Square the result of those substractions, and then average the squares. You will then have the variance.
