A 40-lb container of peat moss measures 14× 20× 30 in. A 40-lb container of topsoil has a volume of 1.9 gal. Calculate the avera
Viktor [21]

The average density of the peat moss in units of g/cm³ is 2.52 g/cm³

<h3>How to convert 40 lb to grams (g)</h3>

We'lol begin by converting 40 lb to grams (g). This can be obtained as follow:

1 lb = 453.592 g

Therefore,

40 lb = (40 × 453.592) / 1 lb

40 lb = 18143.68 g

<h3>How to convert 1.9 gal to cm³</h3>

We can convert 1.9 gal to cm³ as follow:

1 gal = 3785.41 cm³

Therefore,

1.9 gal = (1.9 gal × 3785.41 cm³) / 1 gal

1.9 gal = 7192.279 cm³

<h3>How to determine the density </h3>

The density can be obtained as follow:

  • Mass = 18143.68 g
  • Volume = 7192.279 cm³
  • Density =?

Density = mass / volume

Density = 18143.68 / 7192.279

Density = 2.52 g/cm³

Metals have high melting and boiling points and are often shiny and silvery. Which of the blocks are metals?
DanielleElmas [232]

Answer:

S and p blocks elements are considered metals while d-block elements are considered transition metals.    

Explanation:

s-block consist of lithium, sodium, potassium, rubidium, cesium and francium metals.

All are these called alkali metals.

These metals have one valance electron.

These metals are soft and having low density.

They easily lose their one valance electron and form cation with +1 charge.

They have low melting points.

P- block elements includes beryllium, magnesium, calcium, strontium, barium, radium metals.

They are called alkaline earth metals.

All are these have two valance electrons.

They easily lose their valance electrons and form cation with charge of +2.

These metals are also very soft.

They form salt with halogens.

They are also very reactive metals.

When using 100ml or 50ml graduated cylinder to what decimal place can your volume be estimated?<br>​
Olegator [25]

Answer:

I know that the 100-mL graduated cylinders are always read to 1 decimal place.

I think for 50 mL graduated cylinders, it lets you measure volumes up to 50.0 mL to the nearest 0.1 or 0.2 mL, depending on your exact cylinder.

When benzene (c6h6) reacts with bromine (br2) bromobenzene(c6h5br) is obtained: c6h6 + br2 → c6h5br + hbr what is the theoretica
saveliy_v [14]

Answer A) : We have to calculate the number of moles of Benzene involved in the reaction,

30 g / 78 moles of benzene = 0.384 moles


For bromine it will be the same process,

65 g / 159.8 moles = 0.406 moles


By observing the reaction given above we can say that the reaction ratio of bromine and benzene is 1 : 1


We need to find the mass of bromobenzene,

which should be, 6(12) + 5 (1)+ 79.90 = 156.9 g/mol


So, the mass of bromobenzene will be 156.9 g/mol X 0.3846 mol = 60.343 g


Hence the theoretical yield will be 60.34 g


Answer B) : To calculate the actual yield we have to divide it with theoretical yield.


(56.7g / 60.343 g ) X100% = 93.96 %


Here, we can say that we got 93.96 % of actual yield.


As we know it is impossible to get 100% yield in any reaction.
