Carbide-12 and oxygen-18 are isotopes of carbon and oxygen, respectively. They have different numbers of neutrons in their atomic nuclei compared to the more common isotopes, carbon-13 and oxygen-16. These isotopes are used in various scientific studies, such as radiocarbon dating for carbon-14 and paleoclimatology studies for oxygen-18.

Which statement is true if 12 mol co and 12 mol fe2o3 are allowed to react?
If 12 mol of CO and 12 mol of Fe2O3 are allowed to react, the limiting reactant will be CO. The balanced chemical equation is 3CO + Fe2O3 -> 2Fe + 3CO2, and since it takes 3 mol of CO to react with 1 mol of Fe2O3, there is excess Fe2O3 left after the CO is consumed.
Is it true or false that the atomic number of carbon is 6 so it must contain l2 electrons?
False. The atomic number of an element represents the number of protons in its nucleus. Carbon has an atomic number of 6, so it has 6 protons and typically 6 electrons to maintain a neutral charge, not 12 electrons.
What is the true methane number of methane?
The true methane number of methane is 100. This indicates that methane has the highest resistance to engine knock compared to other hydrocarbons. It is used as a reference fuel for determining the knock resistance of other fuels.
If an atom has 12 protons 13 neutrons and 12 electrons what is the charge of the atom?
It has no charge because the protons (positive) and the electrons (negative) number the same. The charges cancel out, which means it's a neutral atom.
What are all the element that in group 6 call?
All the elements in group 6 are called the transition metals. This is also true for groups 3-12.
What is one fourth of 12 equals 3?

5 plus 7 equals -12 factor equation?
There is no equation. An equation is true, whereas the statement ( 5 + 7 = -12 ) is false.
When was The Statement released?
The Statement was released on 12/12/2003.
Is 12 equals 12 a number sentence?
Yes, "12 equals 12" is a number sentence. It expresses a mathematical statement that asserts the equality of two numerical values. In this case, both sides of the equation represent the same number, 12, making the statement true. Number sentences can be simple equations, inequalities, or expressions that convey a mathematical relationship.
Why you can you do n-12 but not 12-n?
The subtraction is not commutative, it means that n - 12 is not the same as 12 - n, except when n is 12. For example, suppose that we have a statement such as n - 12 = 12 - n. Can we find a value for n which will satisfy our statement?n - 12 = 12 - n (add n and 12 to both sides)n + n - 12 + 12 = 12 + 12 - n + n2n = 24 (divide by 2 both sides)n = 12Check:n - 12 = 12 - n12 - 12 =? 12 - 120 = 0 TrueBut, for all other values of n, the statement is not true. Let's say that n = 20Does 20 satisfies the statement? Check:n - 12 = 12 - n20 - 12 =? 12 - 208 = -8 FalseHence, we cannot write n - 12 as 12 - n for n ≠12.

what- in the figure, line p is a transversal to lines m and n.Which statement must be true?
lines m and n are parallel if x= 12 and y= 54
What is 12 over 16 equal to 3 over 4 times 1?
The answer is: True. 12 over 16, or 12/16 is 0.75, or three quarters, which is also written as 3/4. (because 12 divided by 4 is 3, and 16 divided by 4 is 3) 3 over 4, or 3/4 is also 0.75, or three quarters (again 3/4). Any anything multiplied by 1 is the same value as itself. So the question is basically a statement showing that two fractions are equal to each other. The statement is correct so we "answer" the statement by saying that is is true.
