When an ionic compound dissolves in water:_________.

Chemistry
1 answer:
Katarina [22]3 years ago
5 0

Answer:

a. the negative ends of water molecules surround the positive ions.

Explanation:

Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.

Thus,

NaCl_{(s)}\rightarrow Na^+_{(aq)}+Cl^-_{(aq)}

When the ionic compound dissociates, the cation which is positively charged gets attracted to the oxygen (Negative ends) which is present in the water. The anion which is negatively charged gets attracted to the hydrogen (Positive ends) of the water.

Hence, the correct option is:- a. the negative ends of water molecules surround the positive ions.

the roof of a building is 0.2km^2. during a rainstorm, 5.5 cm of rain was measured to be sitting on the roof. what is the mass i
Nikolay [14]

The mass in kg of the water on the roof after the rainstorm is mathematically given as

The mass of the water on the roof after a rainstorm is 1.1 *10^{10}g  or 1.1*10^{7}kg

<h3>What is the mass in kg of the water on the roof after the rainstorm? </h3>

Generally, the equation for the Area of the roof is  mathematically given as

A=0.20 \times 10^{10} \mathrm{~cm}^{2}

height of the rain =5.5cm

the volume of the rain on the roof =1.1 * 10^{10} CC

Generally, the equation for mass is  mathematically given as

mass=volume*density

&=\left(1.1 \times 10^{10} \mathrm{cC} \times 1 \mathrm{~g} / \mathrm{cc}\right) \\&=1.1 \times 10^{10} \mathrm{~g}

In conclusion, the Mass of the water on the roof after a rainstorm is 1.1 *10^{10}  or $1.1*10^{7}

Asteroids in the main asteroid belt at certain distances from the Sun are in an orbital resonance with Jupiter, creating gaps in
tatyana61 [14]

Asteroids in the main asteroid belt at certain distances from the Sun are in an orbital resonance with Jupiter, the period of a belt asteroid in an 11:5 orbital resonance with Jupiter is mathematically given as

TA=5.4090years

<h3>What is the period of a belt asteroid in an 11:5 orbital resonance with Jupiter?</h3>

Generally, the equation for the ratio is mathematically given as

asteroid in an 11:5 orbital resonance= 11/5

Therefore, with Jupiter at

TJ=11.9years

Hence

11/4=TJ/TA

TA=5/11)*11.9

TA=5.4090years

Predict the sign of the entropy change of the system for each of the following reactions. (a) N2(g)+3H2(g)→2NH3(g) (b) CaCO3(s)→
Andrew [12]

Answer:

a. Negative

b. Positive

c. Negative

d. zero

Explanation:

Entropy is measure of disorder. Positive entropy implies that a system is becoming more disordered. The opposite is true.

(a) N2(g)+3H2(g) → 2NH3(g) Negative because the system is becoming less disordered since the number of gaseous moles is decreasing

(b) CaCO3(s)→CaO(s)+CO2(g)  Positive because a solid produces a gas which is more disorder therefore there is an increase in entropy

(c) 3C2H2(g)→C6H6(g) Negative because the number of moles of a gas decrease meaninng there is less disorder

(d) Al2O3(s)+3H2(g) → 2Al(s)+3H2O(g) zero because the gaseous moles do not change
