QUICK!!!20 POINTS + BRAINLIEST!!!How to test whether a vegetable or fruit can conduct electricity?

Answers

Answer 1

Answer:

Using a *MULTIMETER* is the best way to test and compare each fruit and vegetable. Because each fruits or vegetables all have different conductivity levels!

Hardness, lustre, and colour.

Explanation:

These Rocks shown in photographs are made of different types of minerals which have properties as follows:

●The color of the rock is grey, brown and yellow after it is ground into a powder its color is streak.

● The lustre of the rock tells how shiny the rocks are.

● Other properties include hardness, texture, shape, and size.

Why can't you use the largest objective for some slides

Describe the conditions that are necessary for snow to fall

Answers

the temperature had to be cold both up in the clouds where snowflakes form and down at ground level. If air near ground level is too warm the snow will melt on way down changing to rain or freezing rain also Moisture is needed to form clouds and precipitation.

temperature has to be at least below 34° for snow to fall and it has to be a day where rain would fall

Can aromatic compounds belong to other classes of compounds

Answers

Answer:

Yes

Explanation:

First of all, aromatic compounds are part of a group of compounds known as hydrocarbons. Hydrocarbons are compounds containing only gmhydrogen and carbon. Some aromatic compounds contain more than one benzene ring. These belong to another subgroup known as poly nuclear aromatic hydrocarbons.

Yes , it is possible for aromatic compounds to belong to other classes of compounds.

Write a balanced half-reaction describing the reduction of aqueous vanadium(V) cations to aqueous vanadium(I) cations.

Answers

Explanation:

Reduction is a chemical reaction in which electrons are gained by one of the atoms taking part in the reaction and lowering of an oxidation state of that atom.

Reduction takes place at the cathode.

In aqueous, vanadium(V) is present in +5 oxidation state which on reduction changes to vanadium(I) with +1 oxidation state.

The half reaction is :

$V^(5+)(aq)+4e^- \rightarrow V^(1+)(aq)$

The balanced half-cell reaction for the reduction of aqueous vanadium (V) cations to aqueous vanadium (I) cations is $\boxed{{{\text{V}}^(5 + )}\left({aq}\right) + 4{e^ - }\to {{\text{V}}^(1 + )}\left({aq}\right)}$ .

Further Explanation:

Redox reaction:

It is a type of chemical reaction in which the oxidation states of atoms are changed. In this reaction, both reduction and oxidation are carried out at the same time. Such reactions are characterized by the transfer of electrons between the species involved in the reaction.

The process of gain of electrons or the decrease in the oxidation state of the atom is called reduction while that of loss of electrons or the increase in the oxidation number is known as oxidation. In redox reactions, one species lose electrons and the other species gain electrons. The species that lose electrons and itself gets oxidized is called as a reductant or reducing agent. The species that gains electrons and gets reduced is known as an oxidant or oxidizing agent. The presence of a redox pair or redox couple is a must for the redox reaction.

The general representation of a redox reaction is,

${\text{X}} + {\text{Y}} \to {{\text{X}}^ + } + {{\text{Y}}^ - }$

The oxidation half-reaction can be written as:

${\text{X}} \to {{\text{X}}^ + } + {e^ - }$

The reduction half-reaction can be written as:

${\text{Y}} + {e^ - } \to {{\text{Y}}^ - }$

Here, X is getting oxidized and its oxidation state changes from to +1 whereas B is getting reduced and its oxidation state changes from 0 to -1. Hence, X acts as the reducing agent whereas Y is an oxidizing agent.

Initially, vanadium is present in +5 oxidation state. Its oxidation state changes from +5 to +1 oxidation state. The oxidation state of V is decreased during the reaction so reduction is taking place. The balanced reduction half-cell reaction is as follows

${{\text{V}}^(5 + )}\left({aq}\right) + 4{e^ - }\to {{\text{V}}^(1 + )}\left( {aq}\right)$

An unknown material has a mass of 6.75g and a volume of 9 cm3. What is the density of the material? Round to the nearest tenth?

Answers

Answer is: the density of the material is 0.8 g/cm³.

m(material) = 6.75 g; mass of unknown material.

V(material) = 9 cm³; volume of unknown material.

d(material) = m(material) ÷ V(material).

d(material) = 6.75 g ÷ 9 cm³.

d(material) = 0.75 g/cm³; density of unknown material.
