What is the chemical formula for indium tin oxide?
The code is ITO (but this is not a true chemical formula); this is a mixture of In2O3 and SnO2.
True or false in naming the ionic compounds the cation is always named first and the anion second?
True. In naming ionic compounds, the cation (positively charged ion) is always named first followed by the anion (negatively charged ion). This convention helps identify the elements and their charges in the compound.
Can Changing a subscript changes the formula of the compound true or false?
It not only can change but really DOES change the formula.Changing the subscript in a chemical formula changes the number of atoms to which the particular subscript belongs. Doing this will change the formula completely, making it representative of another substance completely.
Is the formula HCI a base?
If you meant HCl, Hydrochloric Acid, it is a strong acid and not a base. A way to tell if it is an acid is that it has an H+ in the chemical formula. Most of the time, if it is a base it has an OH- attached to the chemical formula, but this is not necessarily true for all bases.
Is it true that the elements that make up a compound are always present in the same proportions?
Yes, that is true for compounds with a fixed chemical formula. In a compound, elements combine in specific ratios based on their valencies to form stable structures. This is known as the law of definite proportions.
Unlike a mixture a compound has a chemical formula that is always the sametrue or false?
True.
What is the chemical formula for indium tin oxide?
The code is ITO (but this is not a true chemical formula); this is a mixture of In2O3 and SnO2.
True or false in naming the ionic compounds the cation is always named first and the anion second?
True. In naming ionic compounds, the cation (positively charged ion) is always named first followed by the anion (negatively charged ion). This convention helps identify the elements and their charges in the compound.
Is the number before a chemical formula indicates how many molecules are involved in a chemical reaction?
Yes, that is true.
Is it true that The chemical formula for the ionic compound consisting of nitride ions and titanium(III) ions is Ti3N.?
No, that is not true. The correct formula would be TiN
What is the chemical formula of soapstone?
Statice is a talc-schist with magnesium, not a true mineral.
What is true about a hydroxide ions?
Hydroxide ions are anions with the chemical formula (OH)-.
Which is not true about the chemical formula of a substances?
which is not true about the chemical formula of a sbstance? a.it gives the number and kinds of atoms present. b.it shows that a substance has a definite compound. c.it shows the elements present in the compound. d.it shows the phase of a substance.
What is always true of a binary compound?
A binary compound always contains two different elements. This means it will have a chemical formula consisting of two elements in fixed proportions. Binary compounds typically involve a metal and a nonmetal.
Can Changing a subscript changes the formula of the compound true or false?
It not only can change but really DOES change the formula.Changing the subscript in a chemical formula changes the number of atoms to which the particular subscript belongs. Doing this will change the formula completely, making it representative of another substance completely.
Is H1.9O1.9 a formula of a compound?
No, H1.9O1.9 is not a valid chemical formula as it implies fractional atoms which is not possible in formula representation. A chemical formula should represent whole numbers of atoms for each element.
NaCl is not a molecule but a formula unit?
Yes, it is correct - NaCl is a formula unit of sodium chloride; ionic compounds hasn't a true chemical formula.
