Answer:

The correct answer is Heterogeneous mixture

Explanation:

Heterogeneous mixture are those mixture in which:

Substance is distributed in non uniform manner.

Two distinct layers are formed

Thus when water and dirt are mixed together it results in the formation of  a heterogeneous mixture and after sometimes two different layers will be observed.

Hence, in the bottle there is a heterogeneous mixture of water and dirt.

Number of feed = 555 pounds

Feed cost = $237.21

The main composition of algebraic expressions are:  

• 1. phrases/terms  

• 2. variable  

• 3. constants  

• 4. arithmetic operations  

• 5. coefficients  

• 6. exponent  

Initial weight = 82 pounds

Goal weight = 267 pounds

The difference in weight that must be achieved :

[tex]\tt 267-82=185~pounds[/tex]

The pig will gain 1 pound for every 3 pounds of feed⇒ 1 pound weight=3 pounds of feed

The amount of feed must be given:

[tex]\tt 185~pounds~weight\times 3~pounds~feed=555~pounds~of~feed[/tex]

Feed costs $21.37 per 50 pound bag, so for 555 pounds :

[tex]\tt (555~pounds\div 50)\times \$21.37=\$237.21[/tex]

Answer:

They are formed by windblown sand collecting around an obstruction. As organic matter is deposited by wind and waves, low herbs colonize the dune. As these plants collect more sand and organic matter, the dune increases in height becoming the fore dune.

Explanation:

Answer:

c. 64 grams

Explanation:

What is the proper combining ratio (by mass) for carbon to oxygen in the reaction that forms carbon dioxide (CO 2)? From the data given in question 1, since 64 grams of oxygen reacts with 24 grams of carbon, the ratio must be 64 to 24, which is 2.7 parts oxygen to 1 part carbon.

Answer: 40.3 L

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]

[tex]\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles[/tex]

[tex]Sb_2O_3+3C\rightarrow 2Sb+3CO[/tex]  

According to stoichiometry :

1 moles of [tex]Sb_2O_3[/tex] produces = 3 moles of [tex]CO[/tex]

Thus 0.600 moles of [tex]Sb_2O_3[/tex] will produce=[tex]\frac{3}{1}\times 0.600=1.80moles[/tex]  of [tex]CO[/tex]

Volume of [tex]CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L[/tex]

Thus 40.3 L of CO is produced.

Answer:

During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

Explanation:

Answer:

It all comes down to form. When the paper is smooth, it exposes a large surface to the air beneath it which slows its descent. Once it is crumpled, the surface which comes in contact with the air is much smaller, allowing it to fall much faster.

How much heat energy required to convert following?

How much heat energy, in kilojoules, is required to convert 47.0 g of ice at -18.0 C to water at 25.0 C ?

Specific Heat of Ice - 2.09 j/g * c

This is how I did it and the answer is wrong...Please check and correct me

Q = m * Cice * Change in Temp

Q = (47.0 g)(2.09 J/g*c)(43) = 4222.6 J * 0.001 kj / j = 4.22 kj
