Write and Balance:<br> Exothermic reaction between aqueous sodium hydroxide and sulphuric acid.
kolezko [41]
Exothermic reaction discharges energy in forms of light, heat or sound, thus it is represented by negative flow of heat. In this equation:
<span><span>
NaOH (aq) + H2SO4 (aq) </span>à<span> H2O (l) + Na2SO4 (aq)</span></span>
<span>
When the solution of Sodium hydroxide is added to the Sulphuric acid, water and Sodium sulfate is produced. To balance this, we put (2) two on Sodium hydroxide and (2) two on water.</span>
<span><u>
2</u><span>NaOH (aq) + H2SO4 (aq) </span>à<u> 2</u><span>H2O (l) + Na2SO4 (aq)</span></span> <span> </span>

Can some one plz help
blsea [12.9K]

The reaction uses B) 9.0 g Br₂.

 iron + bromine ⟶ product

2.0 g +     <em>x</em> g     ⟶   11.0 g

According to the <em>Law of Conservation of Mass</em>, the total mass of the reactants must equal the total mass of the products.

∴2.0 + <em>x</em> = 11.0

<em>x</em> = 11.0 – 2.0 = 9.0

The reaction uses 9.0 g Br₂.

A car at rest ends accelerates for 12 seconds. After this time the car is going 36 m/s. What was its acceleration?
Zigmanuir [339]

Acceleration is defined as velocity per unit time.

Acceleration=\frac{Velocity}{time}

a=\frac{dv}{dt}

Here, a=acceleartion,

v=velocity=36 m/s

t=time=12 s

a=\frac{dv}{dt}

a=\frac{36}{12}

a=3 ms⁻²

A car at rest ends accelerates for 12 seconds. After this time the car is going 36 m/s. So acceleration that is a=3 ms⁻².
