What does NaHCO3 change to when dissolved in H2O?
NaHCO3 is sodium bicarbonate (baking soda.) It is water soluble, and in solution it will dissociate into Na+ ions and HCO3- ions.
What is the molecule weight of c2h4o2?
60.04
What mass of NaHCO3 is needed to neutralize 150ml of 044M HCl?
Several part problem. Get molarity of NaHCO3. (150 ml)( M NaHCO3) = (150 ml)(0.44 M HCl) = 0.44 M NaHCO3 --------------------------- get moles NaHCO3 ( 150 ml = 0.150 Liters ) 0.44 M NaHCO3 = moles NaHCO3/0.150 Liters = 0.066 moles NaHCO3 ---------------------------------------get grams 0.066 moles NaHCO3 (84.008 grams/1 mole NaHCO3) = 5.54 grams NaHCO3 needed ---------------------------------------------answer
What is NaHCO3 commonly called?
NaHCO3 is commonly called bicarbonate of soda or baking soda.
Is it a physical change chemical change when salt dissolves in water?
Physical
Is the chemical reaction for C2H4O2 NaHCO3 a physical change?
No, the reactants acetic acid (C2H4O2) and sodium bicarbonate (NaHCO3) react chemically to make other compounds (products): sodium acetate (NaC2H3O2) and carbonic acid (H2CO3), decomposing easily to carbon dioxide (CO2) and water (H2O)
Is C2H4O2 NaHCO2 a physical change?
No, mixing C2H4O2 and NaHCO2 is not a physical change as it does not alter the chemical composition of the substances involved. It would simply be a physical mixing or dissolution of the two compounds.
How many atoms of hydrogen C2H4O2?
In one molecule of C2H4O2, there are 4 atoms of hydrogen.
If there are 5.00 mol of H How many moles of C2H4O2 are present?
5.00 moles H x 1 mole C2H4O2/4 moles H = 1.25 moles of C2H4O2 present.
Is mixing baking soda and vinegar a physical and chemical change?
It is a chemical change. CH3COOH (vinegar) + NaHCO3 (baking soda) -> CH3COONA (sodium acetate) + H2CO3 (carbonic acid)...which then immediately dissociates to... H2CO3 -> H2O + CO2
What does NaHCO3 change to when dissolved in H2O?
NaHCO3 is sodium bicarbonate (baking soda.) It is water soluble, and in solution it will dissociate into Na+ ions and HCO3- ions.
What chemical is made when baking soda and vinegar mix?
As an overview, acetic acid (HC2H3O2 (or C2H4O2 in solution), from the vinegar) reacts with aqueous sodium bicarbonate (NaHCO3), forming sodium acetate (NaC2H3O2) and carbonic acid (H2CO3). As also happens in carbonated water, the carbonic acid then dissociates into water and carbon dioxide (H2O and CO2). The chemical reaction would be (not balanced): C2H4O2 + NaHCO3 --initial reaction--> NaC2H3O2 + H2CO3 --bubbling--> NaC2H3O2 + H2O + CO2
What is the molecule weight of c2h4o2?
60.04
Chemical formula for sodium hydrogencarbonate?
The answer is NaHCO3
How many moles of NaHCO3 are present in a 6.10 g sample?
Divide 6.10 (g NaHCO3) by 84.007 (g.mol−1 NaHCO3) to get 0.0726 mol NaHCO3
What is the ratio of NaHCO3?
The ratio of NaHCO3 to WHAT!
Is crumple a chemical change or physical change?
Crumple is a physical change.
