What else can I help you with?
If an equation has a negative number is the solution acidic?
No, having a negative number in an equation does not necessarily mean the solution is acidic. The acidity or basicity of a solution is determined by the concentration of hydrogen ions (H+) or hydroxide ions (OH-) present, not by the sign of a number in an equation.
What do you count to decide whether or not an equation is balanced?
If you count all of the atoms of each element on the left and all the atoms of each element on the right and the numbers on the left and right are equal for EVERY element, then the equation is balanced.
Which equation best represents the dissociation of water molecule into hydrogen ions and hydroxide ions?
The equation is: H2O------>H+ + OH-
In a chemical equation can you count the number of molecules?
Yes, you can count the number of molecules in a chemical equation by looking at the coefficients in front of the chemical formulas. Coefficients represent the number of molecules of each substance involved in the reaction. For example, in the equation 2H2 + O2 -> 2H2O, it shows that two molecules of hydrogen combine with one molecule of oxygen to form two molecules of water.
Which ions are not spectator ions in the precipitation equation Pb(NO3)2 plus 2KI -- and gt PbI2 and nbsp plus 2KNO3?
The spectator ions in this precipitation equation are K+ and NO3-. The non-spectator ions are Pb2+ and I-. They combine to form the precipitate PbI2.
If an equation has a negative number is the solution acidic?
No, having a negative number in an equation does not necessarily mean the solution is acidic. The acidity or basicity of a solution is determined by the concentration of hydrogen ions (H+) or hydroxide ions (OH-) present, not by the sign of a number in an equation.
What number should be placed in front of CaSO4 to give the same total number of sulfate ions on each side of the equation?
To balance the number of sulfate ions on each side of the equation, a coefficient of 3 should be placed in front of CaSO4. This will give a total of 3 sulfate ions on each side of the equation.
Can you count the number of atoms in a chemical equation?
Yes, you can count the number of atoms in a chemical equation by taking into account the subscripts of each element within the formula. The subscripts represent the number of atoms of each element present in the molecule. By adding up the total number of each atom on both sides of the equation, you can determine the total number of atoms in the chemical equation.
What do you count to decide whether or not an equation is balanced?
If you count all of the atoms of each element on the left and all the atoms of each element on the right and the numbers on the left and right are equal for EVERY element, then the equation is balanced.
How do you identify the number of terms in an equation?
Carry out all the multiplications and divisions and then count them.
Can the total ionic equation shows the net change in the equation after spectator ions been removed?
Yes, the total ionic equation shows all the ions involved in the reaction, including the spectator ions. To find the net ionic equation, you can remove the spectator ions from the total ionic equation to emphasize the ions that participate in the actual chemical change.
How is a net ionic equation written from a ionic equation?
the spectator ions are removed
Is it true to check that an equation is balanced count the number of atoms of each type on each side of the equation?
Pretty much. To make sure an equation is balanced you'll want to make sure there are the same number of each atom on each side of the equation. So: If there are 5 H's that are reactants, make sure there are 5 H's that are products.
How is a net ionic equation written in a complete ionic equation?
To write a net ionic equation from a complete ionic equation, you remove the spectator ions that appear on both sides of the equation. The remaining ions that participate in the reaction are then included in the net ionic equation. This simplifies the equation to show only the ions that undergo a chemical change.
The unit used for counting umbers of atoms ions or molcules is the?
You generally count them in moles, which is actually a number: 6.02X1023.
Which equation best represents the dissociation of the water molecules into hydrogen ions and hydroxide ions?
The equation is: H2O------>H+ + OH-
