34. Which statement describes what occurs in the

Chemistry
1 answer:
Rudik [331]2 years ago
5 0

Answer:

3 Both mass and charge are conserved.

Explanation:

The equation of the reaction is;

Cu(s) + 2Ag+ (aq) → Cu2+ (aq)  + 2Ag(s)

A redox reaction is an acronym for oxidation-reduction reaction. This refers to a reaction in which the oxidation number of one specie is increased while the oxidation number of the other specie is decreased.

This means that one specie looses electrons while the other specie gains electrons. Here, Cu(s) looses electrons while Ag+(aq) gains electrons from left to right in the reaction.

In a redox reaction, both mass and charge are conserved. This means that the total mass and charge on the reactants side is the same as the total mass and charge on the products side.

Speed is the ratio between distance and <br><br> Pls answer ASP!!
natulia [17]

Answer: Explanation: Speed is simply velocity without a specified direction (speed is the magnitude of the velocity vector). Regardless of the two measurements, they both relate distance to time, but are slightly different. Instantaneous speed is the derivative of the total distance covered with respect to time.

Explanation: I hope this helps!

Which quantity is equivalent to the product of the absolute index of refraction of water and the speed of light in water?
givi [52]

The quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.

<h3>What is the speed of light?</h3>

Speed of light is the rate of speed though the light travels. To find the speed of light in any medium, the following formula is used.

v=\dfrac{c}{n}

Here, (n) is the index of reaction and (c) is the speed of light in the vacuum. The speed of light in the vacuum is almost equal to the 3.0×10⁸ m/s.

Now the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water has to be find out.

The above formula can be written as,

v=\dfrac{c}{n}\\vn=c\\c=vn

Here, the product of index of refraction and speed of light is equal to the speed of light in vacuum. This will be true for water as well.

Thus, the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.

When the [H+] in a solution is 1.7 × 10−9 M, what is the pOH ? 8.80 5.23 14 8.60
kumpel [21]
PH = -log[H+]
pH = -log[1,7×10^-9]
pH = 8,77

pH + pOH = 14
pOH = 14 - 8,77
pOH = 5,23

Use the equation to answer the question
vaieri [72.5K]

CH4 + 2O2→CO2 + 2H2O

Explanation:

CH4 + O2→CO2 + H2O

First look at the C atoms. At first glance they are balanced with 1 C on each side.

Now look at the H atoms. They are not balanced. There are 4 H atoms on the left side and 2 H atoms on the right. Place a coefficient of 2 in front of the H2O. We now have 4 H atoms on both sides.

CH4 + O2→CO2 + 2H2O

Now look at the O atoms. They are not balanced. There are 2 O atoms on the left side and 4 on the right. Place a coefficient of 2 in front of the O2. We now have 4 O atoms on both sides.

CH4 + 2O2→CO2 + 2H2O

The equation is now balanced. Each side has 1 C atom, 4 H atoms, and 4 O atoms.
