Answer:
Lies predominantly to the left.
Explanation:
In the reaction:
NH4⁺(aq) + Br-(aq) ⇄ NH3(aq) + HBr(aq)
Conjugate acid + Ion ⇄ weak base + strong acid
HBr is a strong acid whereas NH3/NH4⁺ are the weak base and its conjugate base. A strong acid as HBr dissociates completely in solution as H⁺ and Br⁻. That means in solution you will never have HBr without dissociation doing the reaction:
<h3>lies predominantly to the left.</h3>
Answer:
None of the above.
Explanation:
The limiting factor of this is the chlorine. You only have 2 moles of chlorine.
2Na + Cl_2 ==> 2*NaCl
The equation tells you that for every mol of Cl2 that you have, you require 2 moles of Na and you get 2 moles of NaCl
So what that means is that if you have 2 mols of Cl2, you need just 4 moles of Na, and you will get 4 mols of NaCl
Since 4 is not one of your choices, the answer is none of the above
Answer:
The correct option are:
1. (b) current
2. (c) potential
3. (b) coulombs (C)
4. (a) amperes (A)
5. (d) volts (V)
Explanation:
Electric charge is a property of a particle, like electron and proton. The subatomic particles, electrons and protons are negatively and positively charged particles, respectively.
The electric charge of a particle can be measured in <em>coulomb, denoted by C</em>.
Current or electric current is defined as the <em><u>net flow of the electric charges through a given region, per unit time.</u></em> Electric current can be measured in <em>ampere, denoted by A.</em>
<em>Potential or Electric potential</em> is described as the work done to displace the electric charges from one point to another. <em><u>Potential is the driving force for the movement of charges</u></em> and can be calculated in <em>volt, denoted by V.</em>
Answer:
Molecules start out unevenly distributed and end up evenly distributed.
Explanation:
Diffusion is the process by which molecules of a substance move from a region of higher concentration to a region of lower concentration until equilibrium is attained.
Molecules start out unevenly distributed and end up evenly distributed in a particular medium. Diffusion occurs due to the particulate nature of matter. When the particles that make up a substance are concentrated at a point, the collide more often with one another causing each molecule to spread out in order to occupy all the available space.
Diffusion occurs in gases, liquids and solids but occurs fastest in gases. Diffusion can be observed for example, in the spread of the smell of a dead rat from one point in a room to every part of the room.
