Answer:

you generally can't convert between units of mass and volume (e.g., grams to gallons).

Explanation: Examples of Conversion Factors Remember, the two values must represent the same quantity as each other. For example, it's possible to convert between two units of mass (e.g., grams to pounds),

According to Arrhenius, NH4+ an acid or a base? Write an equation to support
sergejj [24]

According to Arrhenius definition of acids, NH4^+ is an acid.

According  to Arrhenius  definition of acids and bases, acid is any substance that produces hydrogen ion in solution as its only positive ion.

Following this definition, let us now consider what happens when NH4^+ is introduced into a water;

NH4^+(aq)-------> NH3(aq) + H^+(aq)

Hence, according to Arrhenius definition of acids, NH4^+ is an acid.

For another example of Arrhenius acids, see

What is the molarity of 62grams of ammonium in 5liters of water?
Viefleur [7K]

Answer:

Explanation:

First we need to find how many moles of ammonium weigh 62 grams.

Molar mass of NH4 = (14.0)+(4*1.0) grams

or 18.0 grams/mole

62 (g)/18(g/mole) = 3.444... moles of NH4

If it is dissolved in 5 litres of water, the concentration will be 3.444moles/5L

or 0.6888 M.

Which of the following does not change the energy of the reactants relative to the activation energy?
creativ13 [48]

Answer:

Adding a catalyst

Explanation:

  • Activation energy is the minimum amount of energy needed to start a chemical reaction
  • A Catalyst is a material that increases the rate of a reaction by lowering the activation energy. In other words, a catalyst act to provide an alternative route for the reaction which has a lower activation energy.

What is the concentration of a sodium hydroxide solution if 14.5 mL of it are exactly neutralized by 30.0 mL of a 0.500 M hydroc
rusak2 [61]

Answer:

1.03 M

Explanation:

Step 1: Write the balanced equation

NaOH + HCl ⇒ NaCl + H₂O

Step 2: Calculate the reacting moles of HCl

30.0 mL (0.0300 L) of 0.500 M HCl react.

0.0300 L × 0.500 mol/L = 0.0150 mol

Step 3: Calculate the moles of NaOH that react with 0.0150 moles of HCl

The molar ratio of NaOH to HCl is 1:1. The moles of NaOH that react are 1/1 × 0.0150 mol = 0.0150 mol.

Step 4: Calculate the molar concentration of NaOH

0.0150 moles of NaOH are in 14.5 mL (0.0145 L).

M = 0.0150 mol/0.0145 L = 1.03 M
