Balance this equation by filling in the missing coefficient: 6 CO2 + 6 H2O + Sunlight = C6H12O6 + ?? O2
A. 1
B. 6
C. 12
D. 36

Answers

Answer 1

Given that,

The equation is : [tex]6CO_2+6H_2O+\text{sunlight}\rightarrow C_6H_{12}O_6+?O_2[/tex]

To find,

The missing coefficients.

Solution,

[tex]6CO_2+6H_2O+\text{sunlight}\rightarrow C_6H_{12}O_6+?O_2[/tex]

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

Hydrogen atom = 12

Oxygen atom = 6

If we make the equation as [tex]6CO_2+6H_2O+\text{sunlight}\rightarrow C_6H_{12}O_6+6O_2[/tex]

No the number of atoms in RHS = 6+ 12 = 18

It means if we take the value of ? as 6 the equation will be balanced.

Hence, the correct option is (B) "6".

Given a force of 100.00 N and an acceleration of 5 m/s2, what is the mass of the object?

Answers

Answer:

20 kg

Explanation:

The mass of the object can be found by using the formula

[tex]m = \frac{f}{a} \\ [/tex]

f is the force

a is the acceleration

From the question we have

[tex]m = \frac{100}{5} = 20 \\ [/tex]

We have the final answer as

20 kg

Calculate the new volume if a 13.40 L of a gas at a pressure of 1.51 atm is subject to a new pressure of 65 mmHg.

Answers

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

When placed in distilled water, the pH of metal oxides will be?

Less than 7

Equal to 7

greater than 7

neutral ​

Answers

Neutral they’re equal

When placed in distilled water, the pH of metal oxides will be greater than 7. The correct option is C.

What are metal oxides?

Metal oxides are crystalline solids containing both a metal cation and an oxide anion. In most cases, they react with water to form bases or with acids to form salts.

Metal oxides are compounds that contain two elements, namely a metal and an oxygen atom. Examples include sodium oxide (Na2O), magnesium oxide (MgO), calcium oxide (CaO), and others.

When metal oxides react with dilute acids, they form salt and water, demonstrating that they are basic.

Metal oxides are alkaline. When we dissolve them in water, we get solutions with pH values higher than 7. The reaction between a nonmetal and oxygen produces nonmetal oxides. Nonmetal oxides are highly acidic.

Thus, the correct option is C.

What is depicted in a molecular formula?

Answers

Answer:

Molecular formula describes about number of atoms of each constituent element present in any molecule.

Explanation:

Molecular formula describe about the number and type of atoms in any molecule.  A molecular formula is not a chemical name but instead it is a chemical formula of a compound. A molecular formula consist of chemical symbols for constituent elements followed by numeric subscripts which tells us about number of atoms of each element present in a molecule. For example : Ammonia is a compound of nitrogen and hydrogen i.e NH₃ . As there is only one N atom so we have written only N in it's molecular formula. But as there are 3-H atoms so we have written subscript 3 in H symbol in it's molecular formula. Molecular formula does not tell us anything about shape of molecule .

The DNA would be too difficult to separate without this organization.
The DNA would take up too little space without this organization.
The DNA would be pulled apart rapidly without this organization.
The DNA would be broken without this organization.

Answers

Answer:

The DNA would be too difficult to separate without this organization.

Explanation:

DNA is usually wrapped loosely, but when ready to divide it wraps tighter. It's so each chromosome is a distinct unit. When the cell divides one copy goes to each of the resulting cells. If not lined up properly sereve genetic issues can occur. Chromosome alignment makes the process more efficient.
