You are given a sulfuric acid solution of unknown concentration. You dispense 10.00 mL of the unknown solution into an Erlenmeye

dmitriy555 [2]

Answer:

"0.053457 M" of sulfuric acid.

Explanation:

The given values are:

$V$ = 10 mL solution

$V_{added}$ = 12.20 mL

$V_{total}$ = 22.20 mL

then,

M 0.103 M of NaOH,

$V_{rinsed}$ = experiment will not be affected

$V_{total \ base}$ = 10.38 mL

Now,

⇒ mol of NAOH = MV

= $0.103\times 10.38$

= $1.06914 \ m$

Whether Sulfuric acid, then

⇒ $H_{2}SO_{4} + 2NaOH = Na_{2}SO_{4} + 2H_{2}O$

⇒ $mol \ of \ acid =\frac{1}{2}\times \ mol \ of \ base$

⇒ $1.06914 \ m \ mol \ of \ base = \frac{1}{2}\times 1.06914 = 0.53457 \ m \ mol \ of \ acid$

Before any dilution:

$V_{sample} = 10 \ mL$

⇒ $M \ acid = \frac{m \ mol}{V}$

$=\frac{ 0.53457 }{10}$

$=0.053457 \ M$ (Sulfuric acid)

Animals need various nutrients in order to live and grow. Nitrogen, for example, is a nutrient that is needed to form molecules

Ad libitum [116K]

Answer:

It's A

Explanation:

Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.

In the reaction of nitrogen gas, N2, with hydrogen gas, H2, to form ammonia gas, NH3, how many moles of hydrogen are needed to r

worty [1.4K]

Answer : The correct option is, (E) 6 moles.

Explanation : Given,

Moles of nitrogen = 2 moles

The given balanced chemical reaction is:

$N_2+3H_2\rightarrow 2NH_3$

From the balanced chemical reaction we conclude that,

As, 1 mole of nitrogen gas react with 3 moles of hydrogen gas

So, 2 mole of nitrogen gas react with $2\times 3=6$ moles of hydrogen gas

Therefore, the number of moles of hydrogen gas needed to react with 2 moles of nitrogen gas is, 6 moles.
