Answer:

The answer to your question is E = 419.435 J

Explanation:

Data

Mass = m = 2.004 g

Temperature 1 = T1 = 89°C

Temperature 2 = T2 = 139°C

Specific heat of water = Cp = 4.186 J/g°C

Energy = E = ?

Formula

E = mCp(T2 - T1)

Substitution

E = (2.004)(4.186)(139 - 89)

Simplification and result

E = 8.3887(50)

E = 419.435 J

) Any gas exerts a pressure against its surroundings. For example, if you put more gas in a balloon, it exerts more pressure and

kolezko [41]

Explanation:

As we know that molecules of a gas move far away from each other because they are held by weak Vander waal forces. So, when a balloon is filled by a gas then molecules of a gas strike at its walls leading to more number of collisions.

This will also lead to more expansion of the balloon. As we know that pressure is the force exerted n per unit area of a substance or object.

Thus, more is the kinetic energy of the molecules of the gas more will be the force exerted by them. Hence, more will be the pressure exerted.

Determine if each statement below is True or False regarding Arrhenius and Br∅nsted-Lowry definitions for acids and bases.

Vlad1618 [11]

Answer:

All statements are true

Explanation:

Arrhenius theory:-

The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.

According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, $H^+$ .

Hence, statement 1 is correct.

Bronsted-Lowry base is the specie which accepts the proton form the medium. For example, Benzoate ion is the conjugate base of the benzoic acid. It is a Bronsted-Lowry base and the dissociation of benzoate ion can be shown as:-

$C_6H_5COO^-_{(aq)} + H_2O_{(l)}\rightleftharpoons C_6H_5COOH_{(aq)} + OH^-_{(aq)}$

Hence, statement 2 is correct.

Acetic acid will dissociate as:-

$CH_3COOH\rightleftharpoons CH_3COO^-+H^+$

Hence, statement 3 is also correct.
