Answer:

According to mass and volume,  block density is 2 g/ml

Explanation:

Density is a measure, usually used in physics and chemistry, that relates the mass and volume of a solid or compound.

In general terms, the density is directly proportional to the mass, and inversely proportional to the volume, so increasing the mass will also increase the density.

The formula used to calculate the density is

ρ = [tex]\frac{m}{V}[/tex]

Therefore, according to the mass and density of the block

ρ = [tex]\frac{12}{6}[/tex] = 2g/ml

Being the density of the block equal to 2 g/ml.

The other options are not possible, because the values given do not correspond to the result of the equation.

pH ranges depending on the solution, for a solution with weak acid pH will be between 4.0-7.0.

pH is helps to determine if a solution is acidic or basic in nature.

A pH meter is the instrument that can be used for the measurements.

After series of conversion from one unit to another, the number of gallons was found to be 12 litres

Given Data

Conversion from pounds to Gram

1 kg ---------2.204 lb

x kg ---------184.33 lb

x = 184.33/2.204

x = 83.634 kg

hence the mass in gram = 83.634*1000

mass in gram = 83634 g

Now let us find the volume

We know that density = mass/volume

volume = mass/density

volume = 83634/1.84

volume = 45453.26 cm^3

Convert cm^3 to litres

Volume in litres = 45453.26 /1000

Volume in litres = 45.45 Litres

Convert from Litres to Gallons

1 gallon = 3.79 L

x gallons =  45.45 L

x =  45.45/3.79

x gallons = 11.99 L

Approx = 12 Litres

Answer:

a) there are three transition states

b) there are two intermediates; carbocation and protonated alcohol

c) The first step in the forward direction

Explanation:

The acid-catalysed hydration of alkenes proceeds via a carbocation mechanism.

Three transition states can be identified in this mechanism for the acid-catalyzed hydration of alkenes.

The three transition states are derived from the three steps in the reaction sequence:

1) Protonation of the alkene by hydronium ion

2) Addition of water to the carbocation

3) loss of a proton to yield the alcohol

The first step involves the breaking of a pi bond, hence it is a slow step hence it has the smallest rate constant. The other two steps are fast steps.

Answer:

-I dont have a calculator on me but I can explain to you how to do it and you can put it in your calculator

Explanation:

-First you have to balance the equation because its not balanced

4Na+2H2O —-> 4NaOH

-After you balance it you have to add up the grams of H2 gas,

-The mass of each element is measured in grams

- You find how many grams each element it by looking at the periodic table and looking at the number at the bottom, thats called the mass

- Afterward if the element mass you are looking for has a small number as its subscript, that means there is more than one, so you must add them together to get the correct amount of grams it has

1+1=2grams

-After that, you take that and convert it to moles

2grams x 1mole/(6.02^23)grams = (unknown) moles

-And finally you convert that answer from moles to liters

(Unknown) moles x 22.4 Liters / 1 mole = FINAL ANSWER

Answer:

0.13 M

Explanation:

The reaction equation is;

NaOH(aq) + KHC8H4O4(aq) ------> KNaC8H4O4(aq) + H2O(l)

Molar mass of KHP = 204.22 g/mol

Amount of KHP= mass/ molar mass = 0.3365 g/204.22 g/mol = 1.65 × 10^-3 moles

n= CV

Where;

C= concentration

V= volume in dm^3

n= number of moles

C= n/V = 1.65 × 10^-3 moles × 1000/250 = 6.6 × 10^-3 M

If 1 mole of KHP reacts with 1 mole of NaOH

1.65 × 10^-3 moles of KHP will react with 1.65 × 10^-3 moles of NaOH

From

n= CV

We have that only 12.44 ml of NaOH reacted

C= n/V = 1.65 × 10^-3 moles × 1000/12.44

C= 0.13 M

At the equivalence point, the KHP solution turned light pink.

Answer:

A. More mass

C. Shorter distance between them

Explanation:

The two characteristics of a body experiencing greater gravitational force are that they have mass and a shorter distance between them.

This is conformity with Newton's law of universal gravitation.

The law states that "every object attracts one another with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them".

This law implies that the more the mass of two bodies, the more the gravitational force of attraction. And that the shorter the square of the distance between them, the more the attraction.

Answer:

A. More Mass And

C. Shorter Distance Between Them

Answer:

62.7 gram

Explanation:

Molar mass = (6)(12)+(10)(1)+(1)(32)=114 g/mol

Mass = no of moles × molar mass

= 0.55 × 114 = 62.7 gram

The mass of 0.55 moles of compound C₆H₁₀S is equal to 62.7 g.

A mole is defined as a standard unit that is used to find a huge number of quantities such as atoms, molecules, ions, or other particles. The mass of the 1 mole of any chemical element is equal to the atomic mass of the element and that of any chemical compound is known as molar mass.

The number of entities in 1 mole was found to be equal to 6.023 × 10²³ which is known as Avogadro’s number or Avogadro's constant

Given, the number of moles of the given compound = 0.55 moles

The mass of 1 mole of given compound C₆H₁₀S  = 114 g/mol

The mass of 0.350 moles of the given compound = 0.55 × 114 = 62.7 g

Therefore, 62.7 grams is the mass of 0.55 moles of C₆H₁₀S.
