Answer:
8. the formula of the products are CO2(g) , H2O (l) and NaCl (aq)
Explanation:
s- solid
g- gas
l- liquid
aq- aqueous, means acid
These are the products of the equation, you can balance this by searching up a video on how to do so, or use a balance equations calculator online. Balancing is very easy tho.
Answer:
Explanation:
Hello!
In this case, since the net ionic equations are ionic representations of the molecular equation in which the spectator ions (those at both reactants and products sides) are cancelled out, we first write the complete ionic equation for this reaction, considering that the solid silver chloride is not ionized due to its precipitation:
Whereas the nitrate and sodium ions are cancelled out for the aforementioned reason as they are the spectator ions, to obtain:
Which is the required net ionic equation.
Best regards!
Answer: negatively charged; positively charged electrode.
Explanation:
Electrophoresis can de defined as the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. The electrophoresis of negatively charged particles is called anaphoresis while the electrophoresis of positively charged particles is called cataphoresis.
During proten electrophoresis, due to electric field, proteins migrate through pores in a polyacrylamide gel matrix. It must be noted that pore size decreases with increasing acrylamide concentration.
Proteins set up at a buffer pH of 8.6, the proteins will become negatively charged (that is, anions) and it will move to the positively charged electrode.
Answer:
Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
Time graph plots acceleration values on the y-axis, and time values on the x-axis. In this graph, the acceleration remains constant at 2.0 m/s/s for 10 seconds. Acceleration is defined as a change in an object's velocity, so if an object is accelerating at 2 m/s/s, then every 1 second, the object will gain 2 m/s.
Option A is incorrect because phenol exists in liquid state at room temperature and its boiling point is 181 °C.
Option B is incorrect because there is no ether linkage in phenol. Its chemical formula is Ph-OH.
Option C is correct. As the chemical formula cited above contains hydroxyl group (i.e. -OH).
Option D can be considered incorrect because only one derivative of phenol (<span>Guaiacol</span>)is used as flavoring agent in whisky.
