If 2 grams of substance A reacts with 3 grams of substance B what must be true about the products?
The reaction will form products in a specific ratio based on the stoichiometry of the reaction equation. To determine this ratio, you need to know the balanced chemical equation for the reaction between A and B. The amount of products formed will depend on the limiting reactant in the reaction.
What else can I help you with?
What are the products of neutrilization?
products of neutralization are: water and salt (acidic,basic or neutral) You will nee a base and an acid. If you choose a strong base, then you must use a strong base to neutralize it. You must also remember to add a fitting indicator, like BTB or Phenolphtalein. You will also need appropriate lab equipment.
What things must happen in order that a substance can be smelled?
For a human to smell a substance, The substance must be volatile, and molecules of it must be airborne and drift near the nose. The substance must come in contact with an olfactory nerve-ending in the nose. The olfactory nerve must react, by excitation, to the molecule, sending an electrical impulse to the brain. The brain must receive and process olfactory (smell) nerve signals.
How many moles are in 1.5 grams of iron?
To find the number of moles in 1.5 grams of iron, you need to divide the mass of iron by its molar mass. The molar mass of iron is approximately 55.85 g/mol. So, 1.5 grams of iron is equal to 1.5 g / 55.85 g/mol = 0.027 moles of iron.
When 31 grams of phosphorous reacts with oxygen 71 grams of an oxide phosphorus is the product. What mass of oxygen is needed to produce 13 grams of this product?
To find the mass of oxygen needed to produce 13 grams of the oxide, we first find the molar ratio between P and O in the product. Then, use this ratio to calculate the mass of oxygen needed. Since 71g of the oxide contains 31g of phosphorus, we can calculate the mass of oxygen needed for 13g of the oxide by setting up a proportion.
What are the two criteria that must be met for a substance or a solution to exhibit electrolyte behavior?
For a substance or solution to exhibit electrolyte behavior, it must be composed of ions that can move freely in the solution and the substance must be able to conduct electricity when dissolved in a solvent.
Grams to formula units?
It depends on the substance and its molar mass.In order to convert from grams to formula units, you must first convert grams to moles, then moles to formula units (grams --> moles --> formula units).1. Divide the mass (g) of the given substance by the substance's molar mass.2. Multiply the number of moles found in Step 1 (above) by Avogadro's number (6.022 x 1023).---- Mass substance ----- X 6.022 x 1023 formula unitsMolar mass substanceCONVERSION FACTORMass (g) substance x 1 mol substance ------- x ----- Avogadro's number/////////////////// molar mass (g) substance ------------ 1 mol substance
How many formula units in 47.63 grams?
It depends on the substance and its molar mass.In order to convert from grams to formula units, you must first convert grams to moles, then moles to formula units (grams --> moles --> formula units).1. Divide the mass (g) of the given substance by the substance's molar mass.2.

Reacts with acid to form h2 is physical or chemical property?
This is a chemical property. When a substance reacts with an acid to form hydrogen gas, it indicates a chemical change is occurring at a molecular level, resulting in the formation of new substances with different properties.
In a chemical reaction the total mass of the reactants is 10.0 grams The total mass of the products must be?
The total mass of the products will also be 10.0 grams according to the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
How many grams in 2 gallons?
The two measurements are unrelated in that grams measures weight or mass and gallons measures volume. If the substance is known (i.e. water), a conversion can be made, but the density must be known.
Convert g per mole to grams?
first you must have a mass in mind. eg 345 grams of Carbon divided the mass by the molar weight of the particular substance. In the case of Carbon 12 grams/mole 345 grams/12 grams/mole = 28.75 moles
How many ounces in 50 grams?
1.76 oz 1 oz = 28.34 grams 1 gram = 0.03 oz
How much does 375 cc's weigh?
To convert cc to gram, one must multiple the specific gravity of the substance by the number of ccs to convert to a weight in grams.
How much is 500ml in grams please.?
In order to find out how many grams is in 500ml, one must have a measurement of density available. If density is not known, it can be found by finding the volume of the substance in ml, finding mass in grams, and dividing mass by volume. From there, multiply the result by 500ml to find the amount of grams in 500ml of the substance.
How is the mass in grams converted in to moles?
mol = mass/Mr If the Mr and number of moles of a substance is known then the mass can be calculated. example:- if we have 1 mole of Na, how many grams do we have? mass = mol x Mr mass = 1 x 23 mass = 23g
What measurements must be known in order to find the density of a substance?
To find the density of a substance, you need to know its mass and its volume. The mass is usually measured in grams or kilograms, while the volume can be measured in cubic centimeters or milliliters for solid objects, or in liters for liquids. By dividing the mass by the volume, you can calculate the density of the substance.
For a substance to be considered soluble what concentration of it must dissolve in water?
For a substance to be considered soluble, a significant amount of it must dissolve in water, typically around 0.1 grams or more per 100 mL of water. Solubility can vary greatly between different substances.
