What else can I help you with?
When balancing a chemical equation what is allowed to adjust?
Coefficients of molecules are adjusted.
When balancing a chemical equation can you adjust the script in a formula?
No. Never change the subscripts because then you are changing the formula of the substance to something else. You can only change the amount of a substance by adding a coefficient in front of the formula. If there is no coefficient, it is understood to be 1.
If a solution containing 110.97 g of silver nitrate is allowed to react completely with a solution containing 12.45 g of lithium chloride how many grams of solid precipitate will be formed?
42,09 g silver chloride are obtained.
What is a diophantine equation?
A Diophantine equation is an algebraic equation where only integer solutions are allowed. These equations are named after the ancient Greek mathematician Diophantus of Alexandria, who studied them extensively. They are used in number theory and have applications in cryptography and computer science.
Why do sodium chloride ions separate in water?
After the sodium chloride dissolves in the water, the mixture can be filtered and the carbon residue then rinsed with clean water and allowed to dry. The sodium chloride will reform as solid crystals after the water has evaporated from the filtrate.
When balancing a chemical equation what is allowed to adjust?
Coefficients of molecules are adjusted.
When the equation for the complete combustion of one mole of C3H7OH is blanced the coefficient for oxygen is?
The balanced equation for the complete combustion reaction is 2 C3H7OH + 9 O2 -> 6 CO2 + 4 H2O; therefore, the coefficient for oxygen is 9. If fractional coefficients are allowed, the equation can be written with only one mole of C3H7OH; in that instance the coefficient for oxygen would be 9/2.
When 4 moles of aluminum are allowed to react with an excess of chlorine gas Cl2 how many moles of aluminum chloride are produced?
When 4 moles of aluminum react with an excess of chlorine gas, 4 moles of aluminum chloride are produced. This is because the balanced chemical equation for the reaction is: 2Al + 3Cl2 -> 2AlCl3 This means that 2 moles of aluminum react with 3 moles of chlorine gas to produce 2 moles of aluminum chloride, so 4 moles of aluminum will produce 4 moles of aluminum chloride.
When 0.440 mol of aluminum are allowed to react with an excess of chlorine gas Cl2 how many moles of aluminum chloride are produced?
The balanced chemical equation for the reaction between aluminum and chlorine is 2Al + 3Cl2 -> 2AlCl3. This means that for every 2 moles of aluminum that react, 2 moles of aluminum chloride are produced. Therefore, if 0.440 mol of aluminum is used, it will produce 0.440 mol of aluminum chloride.
When 4 moles of aluminum are allowed to react with an excess of chlorine gas how many moles of aluminum chloride are produced?
When 4 moles of aluminum reacts with an excess of chlorine gas, it forms 4 moles of aluminum chloride. This is because the balanced chemical equation for the reaction is Al + 3Cl2 -> 2AlCl3, indicating a 1:1 molar ratio between aluminum and aluminum chloride.
When 4 moles of aluminum are allowed to react with an excess of chlorine gas CL2 how many moles of aluminum chlorde are produced?
When 4 moles of aluminum react with an excess of chlorine gas (Cl2), 4 moles of aluminum chloride are produced because the balanced chemical equation for this reaction is: 2 Al + 3 Cl2 -> 2 AlCl3 Since the mole ratio between aluminum and aluminum chloride is 2:2, it means that for every 2 moles of aluminum, 2 moles of aluminum chloride are produced.
When balancing a chemical equation can you adjust the script in a formula?
No. Never change the subscripts because then you are changing the formula of the substance to something else. You can only change the amount of a substance by adding a coefficient in front of the formula. If there is no coefficient, it is understood to be 1.
Why is it incorrect to balance chemical equation by changing the subscripts?
Changing subscripts in a chemical formula changes the identity of the compound, which is not allowed when balancing chemical equations. Balancing equations involves adjusting the coefficients in front of the chemical formulas to ensure that the same number of each type of atom is present on both sides of the equation.
What is the allowed chloride content for a boiler water?
10 ppm
What are you allowed to do when you balance an equation?
Change superscripts
What happens when sodium chloride prepared at 608 degree is allowed to cool at room temperature?
At room temperature sodium chloride is a solid.
When sulfuric acid and copper (II) oxide are allowed to react?
When sulfuric acid and copper (II) oxide react, copper (II) sulfate and water are produced. The balanced chemical equation for this reaction is: H2SO4 + CuO -> CuSO4 + H2O.
