If 86.1 g of nitrogen reacts with lithium how many grams of lithium will react
Dovator [93]
Answer:
             128 g of Li will react with 86.1 g of N₂ to completely consume it.

Solution:

The balance chemical equation is as follow,

<span>                                      6 Li  +  N</span>₂     →     2 Li₃<span>N

According to this equation,

               28 g (1 mole) N</span>₂ reacts with  =  41.64 g (6 moles) of Li
So,
                  86.1 g of N₂ will react with  =  X g of Li

Solving for X,
                      X  =  (86.1 g × 41.64 g) ÷ 28 g

                      X  =  128 g of Li

Convert 27.7 kilometers to centimeters.
Stolb23 [73]

Answer:

The correct answer is - 2770000 cm.

Explanation:

1 kilometer = 1000 meter

1 meter = 100 centimeter

1 kilometer = 100*1000 cm

1 km = 100000 cm.

then,

27.7 kilometers = 2.77 × 10^6 centimeters

So, 27.7 kilometers = 27.7 × 100000

= 2.77 × 106 or 2770000 centimeters.

Acidity is a measure of the amount of dissolved hydroxide ions in a solution.
Gekata [30.6K]

The concentration of hydrogen ions in a solution is a measure of its acidity. So the correct option is (b) false.

When an Arrhenius acid is dissolved in water, hydrogen ions are produced:

H+(aq) + A- = HA + H2O (aq)

Here, H+ is the hydrogen cation, A- is the solvated anion, also known as the conjugate base, and HA is the non-dissociated acid. When an Arrhenius base is dissolved in water, hydroxide ions are produced:

BOH + H2O → B+(aq) + OH-(aq)

Is a material with at least one hydrogen atom that has the ability to split apart in an aqueous solution to produce an anion and an H + ion (a proton), creating an acidic solution. Bases are substances that, when dissolved in water, create hydroxide ions (OH) and a cation, resulting in a basic solution.
