how to add chemical compounds?
chemical bonds form between their atoms.
Simple distinguished test between saturated and unsaturated compounds?
add bromine water. unsaturated compounds will decolourize bromine water
Why important to know what elements are in a compound?
yes
Which elements proved difficult for mendeleev to add to his table because they were found to combine in various ratios with other elements?
Copper and magnesium are elements that were difficult for Mendeleev to add to his table because they were found to combine in various ratios with other elements.copper and manganese
Why To balance a chemical equation can we change the formulae of either reactants or products?
if it is a redox reaction sometimes you can add water to help balance the equation
How do you add on a triple beam balance?
You can add it by adding the back and middle the front one is measured by decimals.(example 400+40+0.2=440.2
What are elements and how do they relate to compounds?
An element is a material that has only one kind of atom. For example- hydrogen is an element- it has only hydrogen atoms. Another element is oxygen- it has only oxygen atoms. But if we combine the two elements together, add a spark, we have a bang- and we now have a compound- water. Compounds are 2 or more elements that combine chemically.
How do you balance an RC airplane?
You must find the center of gravity by balancing it. Add weight to the front of the plane. This keeps a flight stable.
What do you add to speed up a chemical reaction?
You can add more of a solid reactant, you can add heat, or you can add a catalyst.
What do you add to art to give it harmony?
balance
Why does it take to long to add new elements to the periodic table?
because they have to discover them. they're not gonna just walk outside to their front lawn and discover a new element
Why you use coefficients in equations?
in order to balance equations, coefficients are placed in front of the various compounds/elements. This is done so that the same number of atoms are produced on each side of the equation. For example: *2*H20 = *2*H2 + 02 The numbers with asterisks on either side of them are coefficients. Without them, there would be only one hydrogen atom on the products side and two on the reactants side. In order to preserve the law of conservation of mass, you must add a coefficient of two. So, you multiply the coefficient by the however many atoms there are. Then, the equation is balanced and your teacher is happy.
how to add chemical compounds?

During which time in the plot should you add elements to intensify the problem?
During the rising action you should add elements to intensify the problem.
Simple distinguished test between saturated and unsaturated compounds?
add bromine water. unsaturated compounds will decolourize bromine water
How do you solve an unbalanced chemical equation?
You add whole-number coefficients as needed until the number of each type of atom is the same on either side of the arrow.Example: given this unbalanced equation: C3H8 + O2 --> CO2 + H2O, you must add some coefficients in front of those substances to make it balance. The solution is: C3H8 + 5O2 --> 3CO2 + 4H2O. Now you can see there's the same number of carbons, hydrogens, and oxygens on each side. Note - the absence of a coefficient means it's understood to be "1".
How do you declare a string array and add elements to it in C plus plus?
You cannot add elements to a fixed array in C or C++. If, however, the array is declared as a pointer to an array, you can add elements by allocating a new array, copying/adding elements as needed, reassigning the new array to the pointer, and deallocating the original array.
