What else can I help you with?
What is the property where you multiply the number on the outside of the parentheses by everything on the inside called?
The distributive property.
What property is it to multiply a sum by a number multiply each addend of the sum by the number outside the parentheses?
Distributive Property
Would you Explain the distributive property?
The distributive property is a property for multiplying with parentheses. It states that a(b+c)=ab+ac. The means that 3(x+2)=3x+6, for example. Basically, the distributive property says you must multiply everything within the parentheses by the number outside the parentheses.
After arranging in descending order what is the first step in factoring polynomials?
Determine the GCF .If it is 1 then continue with the next step but if it is a number such as three then remove that number and divide each monomial by that number and put the polynomial within a set of parentheses with the GCF on the outside of the parentheses
Parentheses two times nine parentheses times negative eight minutes four parentheses four plus hundred plus eight?
parentheses two times nine parentheses times negative eight minutes four parentheses four plus hundred plus eight
What is the percentage by mass of nitrogen in ammonium phosphate NH43PO4. Remember a subscript outside parentheses is multiplied by every subscript inside the parentheses?
28.2%
How do you indicate the number of molecules in a substance?
The subscript outside the parentheses: (H2SO4)2
When a polyatomic ion is in parentheses and there is a subscript on the outside of it is the polyatomic ion multiplied or add?
The subscript outside the parentheses applies to all the elements within the polyatomic ion. It indicates how many of the entire polyatomic ion are present in the compound.
How can one effectively read chemical formulas that contain parentheses?
To effectively read chemical formulas with parentheses, first identify the elements within the parentheses and the number of atoms of each element. Then, apply the subscript outside the parentheses to all elements inside. This helps clarify the composition of the compound and ensures accurate interpretation of the formula.
What does a subscript following a set of parenthesis in a chemical formula indicate?
A subscript following a set of parenthesis in a chemical formula indicates that the entire group enclosed in the parenthesis is to be multiplied by the subscript outside the parenthesis. This is used to show the number of times a group of atoms or molecules is repeated in the compound.
What is the purpose of a subscript in a chemical formula?
The subscript tells you how many atoms of a certain element are in the representative particle of that substance. For example, H2O means 2 hydrogens and 1 oxygen. (The absence of a subscript means there's just 1.) The subscript only applies to the element immediately before it, unless the subscript occurs outside a set of parentheses, in which case it applies to everything inside the parentheses.
How many atoms are in C8H16?
24: The answer to the number of atoms present in a formula that does not include parentheses is always the sum of all the subscript numbers in the formula plus one for each type of atom shown without a subscript. If the formula does contain parentheses, all the subscript numbers inside the parentheses should be multiplied by the subscript number after the closing parenthesis itself before the sum of all subscripts is taken.
Why are parentheses used to write the formula Al(OH)3?
Parentheses are used in chemical formulas to indicate the number of atoms or groups of atoms that are enclosed should be multiplied by the subscript outside the parentheses. In the case of Al(OH)3, it indicates that there are three hydroxide (OH) groups for each aluminum (Al) atom in the compound aluminum hydroxide.
How many carbon atoms in cobalt acetate?
The formula for cobalt acetate is Co(C2H3O2)2. According to the formula, there are four carbon atoms in each formula unit. When an ion is in parentheses, you multiply the subscripts inside the parentheses times the subscript outside the parentheses to find the total number of atoms of an element.
When to use parenthesis when writing ionic compound formulas?
Parentheses are used in ionic compound formulas when multiple polyatomic ions are present. The parentheses are used to indicate a subscript that applies to all the elements inside the parentheses. For example, in the formula for calcium nitrate (Ca(NO3)2), the parentheses indicate that the nitrate ion (NO3) has a subscript of 2.
How many oxygen atoms are there in the formula for aluminum nitrate?
The formula for aluminum nitrate is Al(NO3)3, so there are 9 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
distribute?
Add multiply what is in parentheses and the number that is on the outside of the parentheses that is to the right or to the left.
