What else can I help you with?
Hydroxide positive or negative?
I think it is a positive charge!!
What does calcium carbonate and aluminum hydroxide help neutralize?
SINCE CARBONATE & HYDROXIDE'S ARE NEGATIVE ELEMENTS(eg..OH-) WHEN USED WITH ACIDIC (pH<7)ENVIRONMENT (i.e..POSITIVE ELEMENTS( H+))FORMS A NEUTRAL COMPOUND.HENCE USED FOR NEUTRALIZATION.
Why does hydroxide have a negative charge?
Hydroxide (OH-) has a negative charge because it has gained an extra electron, giving it a net negative charge of -1. This extra electron is acquired when a hydrogen ion (H+) is donated to the hydroxide ion as part of a chemical reaction.
A solution containing equal numbers of hydrogen ions and hydroxide ions is called what?
Technically it is called water because the positive hydrogen ions and the negative hydroxide ions would attract to form a compound with two hydrogen molecules and one oxygen molecule. H2O. This occurs most often in acid-base neutralization reaction where water is a product of the reactions.
What would the formula be if calcium and hydroxide became a compound?
As calcium forms the 2+ ion, and hydroxide has a negative charge, the formula would be Ca(OH)2
What does the negative sign on the value of an enthalpy of formation indicate?
A negative enthalpy of formation indicates that energy is evolved.
In neutralization reaction the negative ions of the salt come from a what?
The negative ions of the salt come from the acid used in the neutralization reaction. When an acid reacts with a base, the hydrogen ions from the acid combine with the hydroxide ions from the base to form water, leaving behind the negative ions of the salt.
Is the enthalpy of formation always negative?
No, the enthalpy of formation can be positive, negative, or zero, depending on the specific chemical reaction and the substances involved.
What does a negative enthalpy indicate in a chemical reaction?
A negative enthalpy in a chemical reaction indicates that the reaction is exothermic, meaning it releases heat energy to the surroundings.
Does Ice melting have a positive or negative enthalpy?
Negtive
Do hydroxide atoms have a negative charge?
The hydroxide ion, OH-, has a negative charge of 1-.
What happens when you mix an acid with a hydroxide base?
When an acid is mixed with a hydroxide base, a neutralization reaction occurs resulting in the formation of water and a salt. The hydrogen ions from the acid combine with the hydroxide ions from the base to form water, while the positive and negative ions from the acid and base combine to form a salt.
What are two things produced by neutralization?
Two things produced by neutralization are water and a salt. Water is formed as a result of the reaction between the hydrogen ions from an acid and the hydroxide ions from a base. A salt, which is an ionic compound, is formed when the positive ions from the base combine with the negative ions from the acid.
What kind of enthalpy change favors a spontaneous reaction?
For a spontaneous reaction, the overall change in enthalpy should be negative (exothermic). This means that the products have a lower enthalpy than the reactants, releasing energy in the form of heat.
Hydroxide positive or negative?
I think it is a positive charge!!
Is the reaction endothermic or exothermic, and what is the enthalpy of the reaction?
The reaction is exothermic, meaning it releases heat. The enthalpy of the reaction is negative, indicating that it is exothermic.
How do you know if an enthalpy change diagram is endothermic or exothermic?
If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.
