A block is pulled 0.90 m to the right in 2.5 s.

Chemistry
1 answer:
Blizzard [7]3 years ago
7 0

The block’s average speed : 0.36 m/s

<h3>Further explanation</h3>

Distance is the length traveled by an object within a certain of time .  

Average speed = total distance/total amount of time ,

Can be formulated :

\tt avg.s(speed)=\dfrac{\Delta D}{\Delta t}

ΔD= total distance

Δt= total time

A block is pulled 0.90 m to the right in 2.5 s :

ΔD= total distance = 0.9 m

Δt= total time = 2.5 s

The block’s average speed :

\tt avg.s=\dfrac{0.9}{2.5}=0.36~m/s

What is the name of the following compound? A line-angle formula shows a ring with six vertices and a circle inscribed. A Cl ato
ozzi

Answer: Option C. p-dichlorobenzene and 1,4-dichlorobenzene.

Explanation:

A line-angle formula with six vertices and a circle inscribed corresponds to the compound known as benzene.

Further, according to the IUPAC standards for naming benzene derivatives, you must first number the position of the substituent. In this case, the substituents (chloros) are located at the positions 1 and 4; also, for the benzene derivatives when they have 2 substituents and the positions are 1 and 4, this configuration is known as <em>para </em>or <em>p </em>configuration.

Additionally, this compound has 2 substituents (chloros) so you have to indicate this number (di).

Therefore, the correct answer is C. p-dichlorobenzene and 1,4-dichlorobenzene.

A voltaic cell is constructed using the following half-reactions: Ag+(aq) + e- ---&gt; Ag(s) EoAg+ = +0.80 V Cu2+(aq) + 2e- ---&
Anton [14]
- Standard reduction potential of Ag/Ag⁺ is 0.80 v and that of Cu⁺²(aq)/Cu⁰ is +0.34 V.
- The couple with a greater value of standard reduction potential will oxidize the reduced form of the other couple.
Ag⁺ will be reduced to Ag(s) and Cu⁰ will be oxidized to Cu²⁺
Anode reaction: Cu⁰(s) →  Cu²⁺ + 2 e⁻     E⁰ = +0.34 V
Cathode reaction: Ag⁺(aq) + e → Ag(s)     E⁰ = +0.80 V 
Cell reaction: Cu⁰(s) + 2 Ag⁺(aq) → Cu⁺²(aq) + 2 Ag⁰(s)
E⁰ cell = E⁰ cathode + E⁰ anode
            = 0.80 + (-0.34) = + 0.46 V
