Answer: The statement, chemicals that you begin with found on the left side of the equation, describes reactant and where they are in a chemical equation.

Explanation:

An equation that includes symbolic formulas and represents chemical reaction between the substances initially present forming new substances is called a chemical equation.

For example, [tex]N_{2} + 3H_{2} \rightarrow 2NH_{3}[/tex]

Here, substances [tex]N_{2}[/tex] and [tex]H_{2}[/tex] are the reactants. Reactants in a chemical equation are always present on the left side as these are the chemicals we begin with.

Also here, [tex]NH_{3}[/tex] is the product. Product(s) in a chemical equation are always present on the right side as these are the chemicals we end with.

Thus, we can conclude that the statement, chemicals that you begin with found on the left side of the equation, describes reactant and where they are in a chemical equation.

Answer:

(ii) 1 dye

(iii) Food coloring F is insoluble in the solvent

(iv) 'E' and 'H'

(b) Food colouring G

Explanation:

Paper chromatography principle is based on the rates of migration of chemicals across a sheet of paper which are different and it consists of a stationary phase such as the water in the paper and a mobile phase such as the solvent resulting in the partitioning of the components of the mixture across the paper

The solution components are positioned to start in one place from where they migrate and separate out on the chromatography paper

(ii) The number of components into which the food colouring 'H' separates into = 1

Therefore, the number of dyes in food colouring 'H' = 1 dye

(iii) Food coloring 'F' does not move because it is insoluble in the solvent, which is the mobile phase

(iv) The food colouring that contains the dye that is likely to be most soluble in the solvent are does for which the dyes travel furthest, which are;

Food coloring 'E' and 'H'

(b) Using a similar question solution found on 'tutor my self' website, we have;

The [tex]R_f[/tex] values are given as follows;

[tex]R_f = \dfrac{Distance \ moved \ by \ dye}{Distance \ moved \ by \ solvent}[/tex]

The distance moved by the solvent = 5 units

The distance moved by dyes in food colouring 'E' and 'H' = 4 units

The distance moved by dye in food colouring 'G' = 3.3 units

The distance moved by the second dye in food colouring 'E' = 2.7 units

By inspection, we get;

[tex]R_f[/tex] dye in food colouring 'G' = 3.3/5 = 0.66,

Therefore, the dye with [tex]R_f[/tex] value closest to 0.67 is the dye in food colouring 'G'.

Which can be converted back to °C by subtracting 273

Once again thus answer can be found using the gas law P1/T1 =P2/T2

Remember to convert to Kelvin before doing the calculations by adding 273

Answer:

d- 7.58 L

Explanation:

According to Charles's law, the temperature in Kelvin is proportional to the volume of a dry gas when the pressure is constant.

Mathematically, V1/T1 = V2/ T2

V1= initial volume= 6.6 L

T1= Initial temperature= 115 °C= (115 °C +273)=388K

V2= final volume

T2= final temperature= 173 °C= ( 173 °C+ 273)= 446K

Substitute the values,

V2=( V1 × T2)/ T1

= (6.6×446)/388

= 2943.6/388

= 7.6L

Answer:

A

Explanation:

Your answer would be A because Earth is formed from cold gases collapsing due to gravity. The Solar System was formed when a huge amount of dust and gas began to collapse under its own gravity, and as the cloud collapse it started to spin causing the material within the cloud to gather into a swirl and then formed into planets and as the planets are formed they kept this spinning motion.

Answer:

See Explanation

Explanation:

If we consider the conductivity values of group A compounds, we will notice that all group A compounds all possess a very high conductivity values each.

These high conductivity values are consistent with ionic compounds which completely dissociate in solution thereby making mobile ions available.

Hence, group A compounds are ionic and completely dissociate in solution.

Explanation:

Yes, I think that Barcelona has large temperature changes throughout the year because Barcelona has minimum temperature of 33°F in winter season and maximum temperature of 88°F in summer season. In Barcelona, the summers are short, warm, and humid while on the other hand, the winters in Barcelona are long, cold, and partly cloudy. The temperature typically varies from 40°F to 83°F and is rarely goes below 33°F or above 88°F.

Answer: depositing

Explanation:

Answer:

C.

Explanation:

C represents butane ([tex]C_{4} H_{10}[/tex])

The statement, that describes the following represent C₄H₁₀ is "C."

Butane, often known as n-butane, is an alkane having the formula C₄H₁₀. At room temperature and atmospheric pressure, butane is a gas. Butane is a highly flammable, colourless gas that vaporises quickly at ambient temperature.

Butane is derived from the root but- and the suffix -ane. It is a straight chain alkane with four carbon atoms. That is, the C₄H₁₀ structure has four carbon atoms bonding with ten hydrogen atoms, all of which are bonded with single bonds.

Hence the correct option is C.

Answer:

water is liquid state of matter

Answer:

1.26moles

Explanation:

To get the number of moles (n) in an element, we divide the number of molecules of the element by Avagadro number (6.02 × 10^23)

n = no. of molecules ÷ nA (6.02 × 10^23)

According to this question, number of molecules of Neon (Ne) is 7.6 x 10^23 particles.

n = 7.6 x 10^23 ÷ 6.02 × 10^23

n = 7.6/6.02 × 10^(23-23)

n = 1.26 × 10^0

n = 1.26moles

Steps 6m, 0.003 moles

Compute an expression comprised of Factors that appear either in a6m or 0.003 moles

Explanation:

Taking into account the definition of molarity,  0.005 liters of a 6.0 M solution of acetic acid contain 0.0030 moles​.

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]molarity=\frac{number of moles}{volume} [/tex]

Molarity is expressed in units [tex]\frac{moles}{liters} [/tex].

In this case, you have a 6.0 M solution of acetic acid that contain 0.0030 moles​. Replacing in the definition of molarity:

[tex]0.6\frac{moles}{liters} =\frac{0.0030 moles}{volume} [/tex]

Solving:

0.6 [tex]\frac{moles}{liters} [/tex]× volume= 0.0030 moles

volume= 0.0030 moles ÷0.6 [tex]\frac{moles}{liters} [/tex]

volume=0.005 liters

Finally, 0.005 liters of a 6.0 M solution of acetic acid contain 0.0030 moles​.
