what is the total number of grams of NaOH needed to react completely with 196 grams of H2 SO4? regents

8090 [49]

Answer:

160 g

Explanation:

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

For $H_2SO_4$ :-

Mass of $H_2SO_4$ = 196 g

Molar mass of $H_2SO_4$ = 98 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{196\ g}{98\ g/mol}$

$Moles\ of\ Sulfuric\ acid= 2\ mol$

According to the given reaction:

$2NaOH+H_2SO_4\rightarrow Na_2SO_4+2H_2O$

1 mole of sulfuric acid reacts with 2 moles of NaOH

So,

2 moles of sulfuric acid reacts with 2*2 moles of NaOH

Moles of NaOH must react = 4 moles

Molar mass of NaOH = 40 g/mol

<u>Mass = Moles*molar mass = $4\times 40\ g$ = 160 g</u>

Which of the following contains plasma?

UNO [17]

Answer:

It is mostly water (up to 95% by volume), and contains dissolved proteins (6–8%) (e.g. serum albumins, globulins, and fibrinogen), glucose, clotting factors, electrolytes (Na+, Ca2+, Mg2+, HCO3−, Cl−, etc.), hormones, carbon dioxide (plasma being the main medium for excretory product transportation) and oxygen.

hope this helps :)

Predict the charge on the monatomic ions formed from the following atoms in binary ionic compounds in the following order: Magne

Drupady [299]

The charge on the monatomic ions of Magnesium, Aluminum, Strontium, and Nitrogen are +2, +3, +2, and -3.

<h3>What is the charge on the ions of atoms of Magnesium, Aluminum, Strontium, Nitrogen?</h3>

The charge on an ion is due to the valency of the atom.

The charge on the ion shows the number of electrons gained or lost by the atom in order to form an ion.

The charge on an ion depends on the group the element belongs to.

Therefore, the charge on the monatomic ions of Magnesium, Aluminum, Strontium, and Nitrogen are +2, +3, +2, and -3.

What is the volume, in liters, of 5.500 mol of C3H3 gas at STP

ZanzabumX [31]

Answer:

123.2 Liters.

Explanation:

At STP (T = 273K & P = 1atm)<em>, one mol of any gas will occupy 22.4 liters</em>.

With the above information in mind, we can <u>calculate how many liters would 5.500 mol of gas occupy</u>:

5.500 mol * 22.4 L / mol = 123.2 L

So 5.500 moles of C₃H₃ would have a volume of 123.2 liters at STP.
