Answer:

There might be some problem in the engine's cooling system.

Explanation:

There are many reasons why your car could be overheating, but the basic process of overheating involves a problem with the vehicle's cooling system that doesn't allow heat to leave the engine compartment. This is often due to a leak or blockage somewhere in the engine cooling system or other components.

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>

Basic substance formed by Chlor- alkali process

Andre45 [30]

The chloralkali or chlorine-alkali industry is an essential component of the chemical industry and generates sodium hydroxide and chlorine via the electrolysis of NaCl (table salt). The prime raw material is brine, that is, a saturated solution of NaCl, which is attained from the deposits of natural salt.

The products of this industry possess various essential uses like chlorine is used as a disinfectant, and is used to purify water, and for various other uses. Caustic soda or sodium hydroxide is also used for various applications like making cleaning agents and soap, making paper, purifying bauxite, and making rayon.
