Is it true that Graphs are representations of equations?
truetrue
Is this statement true or falseA system of linear equations is a set of two or more equations with the same variables, and the graph of each equation is a line?
true
What quantity can always be used in the same way as moles when interpreting balanced chemical equations?
The number of molecules
Why does a CPU evaluate the expression 'a' equals 'a' as true?
CPUs, when given mathematical equations, apply the laws of mathematics to those equations. The equation a = a is true by the reflexive property of equality.
What does it mean for a system of linear equations to have no solutions?
It means that there is no set of values for the variables such that all the linear equations are simultaneously true.
Is this true about balanced chemical equations that they provide the molar ratios of reactants and products in chemical reactions?
Yes.
Is chemical equations required to be balanced?
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
How Chemical equations are balanced by changing the subscripts of the molecule true or false?
False. Chemical equations are balanced by changing the coefficients in front of the chemical formulas, not the subscripts within the formulas. The number of atoms of each element must be equal on both sides of the equation to ensure that mass is conserved.
Equations show each side is equal as far as the number of atoms and molecules?
In a balanced chemical equation, the number of atoms of each element on both the reactant and product sides are equal, ensuring the law of conservation of mass is satisfied. This balance signifies that no atoms are created or destroyed during a chemical reaction, but instead rearranged.
What do balanced equations describe?
Mole Ratios
What do balanced and unbalanced chemical equations share in common?
Both balanced and unbalanced chemical equations represent the chemical reactions that take place between reactants to form products. The key difference is that balanced equations have an equal number of atoms of each element on both sides, while unbalanced equations do not.
What do balanced equations reflect the law of?
Conservation of mass.
which of the following equations is balanced?
2na+s-2nas
Are moles conserved in a balanced chemical equations?
Yes, moles are conserved in a balanced chemical equation according to the law of conservation of mass. This means that the total number of moles of each element involved in a chemical reaction remains constant before and after the reaction.
What are some equations that are not balancing?
Some examples of unbalanced equations include: CH4 + O2 -> CO2 + H2O (the number of oxygen atoms is not balanced) Mg + HCl -> MgCl2 + H2 (the number of chlorine atoms is not balanced)
Properly balanced equations are necessary for what?
Properly balanced equations are necessary in chemistry to accurately represent the conservation of mass and atoms in a chemical reaction. Balanced equations ensure that all reactants are accounted for and that the number of atoms remain the same on both sides of the reaction.
Balanced chemical equations demonstrate?
the law of conservation of mass.
