What does the small number at the bottom corner of a number mean?
This is called a subscript, and is often used in chemical formulas. For example, C6 is 6 carbon atoms, and O2 is two oxygen atoms.
What causes chemical erosion?
Chemical weathering is primarily cause by small amounts of acid that are in rainwater.
A coiled tube in which chemical digestion occurs?
The small intestine is a coiled tube in which chemical digestion occurs.
What basic force is so small it has no chemical significance?
gravity
What is a chemical particle?
A chemical particle refers to the small portion of matter that make a particular chemical. For instance, the helium nucleus is an alpha particle with 2 neutrons and 2 protons.
Why are the numbers all so small and written lower than normal in chemical formulas?
The subscript Number of atoms of that element in the molecule.
What are real life uses of exponents?
Scientific notation is a way to write very large or very small numbers using exponents. For example 2000 is 2x103 . We can do the same thing with negative exponents and write very small numbers like 1/2000 which is 2x10-3 . So one real life use of exponents in in scientific notation.
How do you write 630 with prime numbers and exponents?
First you separate it into prime factors (start looking for small factors, such as 2, 3, 5). Then, you combine the factors with exponents.
What are the small numbers in formulas used to tell how many atoms are present?
subscripts
When using scientific notation negative exponents are very useful when writing what kinds of numbers?
Very very small numbers as for example 0.00000078 = 7.8*10^-7 in scientific notation
What do exponents mean?
exponents are the little numbers on top of a big number. It means you have to mulitply that number by itself that many times. if the exponent is 6, and the number is 8, you have to do 8 times 8 6 times. 86 That small number six is that exponent.
How do you write exponents in expanded form?
Let's say it's 25 I cant make the numbers small so the let's say the 5 is small. You will write it like this 2x2x2x2x2 because you put the 2 each time and the 5 tells u how much times to do and exponents are repeated multiplication next time pay attention in class
Why do you use exponents?
Exponents are used in many different contexts and for different, though related, reasons. Exponents are used in scientific notation to represent very large and very small numbers. The main purpose it to strip the number of unnecessary detail and to reduce the risk of errors. Exponents are used in algebra and calculus to deal with exponential or power functions. Many laws in physics, for example, involve powers (positive, negative or fractional) of basic measures. Calculations based on these laws are simper if exponents are used.
What is meant by nonstoichiometric?
"Non-stoichiometric" refers to a solid chemical compound in which the numbers of atoms of the elements present cannot be expressed as a ratio of small whole numbers.
What is the difference between scientific notation and negative exponents?
Scientific notation is a way to express very large or very small numbers. For very large exponent is positive; for very small exponent is negative. For example, 1,000,000 is 1 x 10 to the plus 6 exponent; 0.000001 is 1 x 10 to the negative 6 exponent
What is a real number in computing?
The so-called "real numbers" are simply numbers that permit decimals. Think of them as numbers in scientific notation, which allow very big or very small exponents (somewhere in the range of -300 to +300), and about 15 significant digits. Since their precision is not unlimited, they do not exactly correspond to what is called "real numbers" in mathematics.
How do you use negative numbers during everyday life?
Negative numbers are often found in measurements. They are used to represent numbers that have sunk below 0 (ex: temperature, debt) or have become the inverse of a number (velocity, energy, negative exponents). Without machines of sorts negative numbers are very rare in everyday life, but so are very large numbers or very small numbers.
