If it takes 5 hours to produce 8.0 kg of alcohol, how any days will it take to consume 1000 kg of glucose?

Answer:

The students should create a project in which they each look at a unique trait that each have (for example, detached ear lobes) and look at their parents to see if they too have this trait. To take it a step further, look at their grandparents for this trait, and ask them about their parents and if they have this trait, this could tell them whether the trait has always, been apparent within the family, if it skipped a generation, or the genetics of one parents were more dominant then the other.

Water boils when the vapour pressure is least the atmospheric pressure.

The atmospheric pressure is equal at the top of the mountain.

The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth.

As we go up in altitude the air pressure becomes less. When the pressure decreases, it takes less energy to get the water molecules to escape the surface. So the temperature is less than it would be at sea level.

Air pressure is higher or greater at the bottom of a mountain. This is because the height of the air above that level is thicker than at the top.

Pressure is given by the equation, P=rho*g*h, where rho is the air density, g is the gravity value and h is the thickness of the air layer on top of the level where we are considering the pressure.

Therefore, as we can see, at the bottom of the mountain, the thickness h of air is greater, and so is the pressure.

Hence, water boils when the vapour pressure is least the atmospheric pressure and the atmospheric pressure is equal at the top of the mountain.

Explanation:

Answer:

V₂ = 238.05 L

Explanation:

Given data:

Final volume = ?

Initial volume = 13.40 L

Initial pressure = 1.51 atm

Final pressure = 65 mmHg ( 65/760 = 0.085 atm)

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

1.51 atm × 13.40 L = 0.085 atm × V₂

V₂ = 1.51 atm × 13.40 L /  0.085 atm

V₂ = 238.05 L

Answer:

Explanation:

The reaction equation is given as:

        N₂  +   3H₂  →    2NH₃  

Mass of NH₃    =  35.5g

Problem:

How many liters of H₂ are needed to produce 35.5g of NH₃  

Solution:

To solve this problem, let us find the number of moles of NH₃;

           Number of moles  = [tex]\frac{mass}{molar mass}[/tex]

Molar mass of NH₃   = 14 + 3(1)  = 17g/mol

 So;

            Number of moles  = [tex]\frac{35.5}{17}[/tex]  = 5.07mole

From the balanced reaction equation:

               2 mole of NH₃   will be produced from 3 mole of H₂  

               5.07mole of NH₃ will produce  [tex]\frac{5.07 x 3}{2}[/tex]   = 7.61mole of H₂

At STP;

       1 mole of gas will occupy 22.4L

     7.61 mole of H₂ will occupy 7.61 x 22.4  = 170.4L

Answer:

All of them have a nucleus..

Explanation:

Pretty simple stuff.  There's no cell without one.

Carlita’s body is made up of many cells. The one thing that all her cells have in common is they have the same kind of genes.

Genes are tiny pieces of spherical hereditary material that are bead-shaped and found on chromosomes. They hold the organism's genetic makeup. The number of genes on each chromosome is incalculable.

The hereditary material that makes up chromosomes is arranged in x shapes inside the nucleus. DNA, genes, and proteins make it up. An organism's genotype is distinct from other organisms because of its distinct genetic makeup, and this distinction can be passed down from one generation to the next.

Traits may be influenced by genes, the environment, or a mixture of the two. Quantitative features can also be qualitative, such as eye colour (such as height or blood pressure).

Therefore, numerous cells make up Carlita's body. Her cells all share the same type of genes, which is the only thing that unites them.

Let the value of ? is x.

It is the equation of photosynthesis.

In LHS,

Carbon atoms = 6

Hydrogen atom = 12

Oxygen atom = 18

In RHS,

Carbon atoms = 6

Answer:

A. write balanced chemical equation (including states), for this process.

Explanation:

Almost all hydrocarbon 'burn' reactions involve oxygen; it's by far the most reactive substance in air.  

Hydrocarbon combustions always involve  

[some hydrocarbon] + oxygen --> carbon dioxide + steam.  

C6H6(l) + O2 (g)--> CO2 (g)+ H2O (g)

Balance carbon, six on each side:  

C6H6(l) + O2 (g)--> 6CO2 (g)+ H2O (g)

Balance hydrogen, six on each side:  

C6H6(l) + O2 (g)--> 6CO2(g) + 3H2O (g)

Now, we have fifteen oxygens on the right and O2 on the left.  

Two ways to deal with that. We can use a fraction:  

C6H6 (l)+ (15/2)O2 (g)--> 6CO2 (g)+ 3H2O (g)

Or, if you prefer to have whole number coefficients, double everything  

to get rid of the fraction:  

2C6H6 (l)+ 15O2 (g)--> 12CO2 (g)+ 6H2O (g)

With the SATP states thrown in...  

C6H6(l) + (15/2)O2(g) --> 6CO2(g) + 3H2O(g)

Answer:

Ans => C => 43.3%

Explanation:

2CO + O₂ => 2CO₂

Given     1g CO = 1g/28g·mol⁻¹ = 0.036 mol CO

b/c coefficient of CO = coefficient of CO₂ => moles CO₂ = 0.036 mol = 0.036mol x 44g/mol = 1.57 gCO₂ (theoretical yield)

%Yield = (actual yield/theoretical yield) x 100% = (0.68g/1.57g) x 100% = 43.3%

Answer:

calcium oxide

Explanation:

its stable

There are several metals which can be used to reduce the metal oxides to corresponding metals. Carbon is an efficient reducing agent. Here Calcium oxide cannot be reduced to calcium by carbon. The correct option is C.

The reaction of metals with oxygen result in the formation of oxygen containing compounds called metal oxides. The binary compounds of oxygen with lesser electronegative elements are called oxides. Most of the stable oxides have 'O' in its -2 oxidation state. Na₂O, CO₂, etc. are some oxides.

Carbon is a reducing agent and it is present above the elements like 'Zn', 'Cu', 'Fe', 'Ag', etc. in the electrochemical series. But the oxides of highly reactive metals cannot be reduced with carbon. Because these metals have more affinity for oxygen than carbon.

The highly reactive metals are extracted by using the electrolytic reduction of their molten chloride. It is not possible for carbon to reduce the oxides of metals like 'Na', 'Ca', 'Al', etc.

Thus the correct option is C.
