when you burn wood in a campfire, ____ energy is converted to ____ and light energy.

Answer:

There are four laws of thermodynamics that define fundamental physical quantities (temperature, energy, and entropy) and that characterize thermodynamic systems at thermal equilibrium.

Explanation:

Answer:

6 carbon atoms

Explanation:

For instance, we can say that one molecule of glucose has 6 carbon atoms, or we can say, equivalently, that one mole of glucose has 6 moles of carbon atoms

Answer:

Decomposition reactions require an input of some form of energy. For example, under the influence of an electric field, water breaks down to give hydrogen and oxygen. In the presence of sunlight, hydrogen peroxide decomposes into oxygen and water.

Explanation:

The reaction can be said to be a single replacement reaction if one substance in a chemical reaction is replacing another one.

For example:

            A + BC →  AC + B

In such reactions there is a replacement of a metallic ion in solution by a metal atom higher in the activity series than the metal in solution.

The relative positions of the two elements in the activity series provides the driving force for a single replacement reaction. If one element that is to replace another in a compound is more active, the reaction will occur. If it is less reactive, there will be no reaction.

Answer:

0.0045

Explanation:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

for example 4.5×10⁻³

In standard notation

4.5 / 10³

0.0045

The expanded notation is standard notation of writing the numerical values which is normal way. The numbers are written as they are, without the power of 10.

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".

B. Pulmonary Circulation

Explanation:

Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart.

An earthworm has a closed circulatory system.

The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm.

As important as they are alive for distributing nutrients and organisms and decomposing matter, worms are also very important in the food chain. They provide a crucial protein-rich source of food for other important species like birds, hedgehogs and frogs.

They may live up to eight years, though one to two is more likely. Full size for an earthworm varies among species, ranging from less than half an inch long to nearly 10 feet.

Explanation:

The molecular formula uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule. :)

Answer:

30.11×10²³ molecules

Explanation:

Given data:

Mass of NaOH = 200.0 g

Number of molecules of water formed = ?

Solution:

Chemical equation:

2NaOH + H₂SO₄      →     2H₂O + Na₂SO₄

Number of moles of NaOH:

Number of moles = mass/molar mass

Number of moles = 200 g/ 40 g/mol

Number of moles = 5 mol

Now we will compare the moles of NaOH and H₂O.

                      NaOH         :        H₂O

                          2             :          2

                         5              :            5

Number of molecules of water:

1 mole contain 6.022×10²³ molecules

5 mol × 6.022×10²³ molecules / 1mol

30.11×10²³ molecules

Explanation:

Which is more reactive hydrogen or oxygen?

Hydrogen is not particularly reactive. For example, just mixing hydrogen and oxygen gas will not cause a reaction at room temperature, but many metal elements oxidize at least on the surface in air. ... It is combustible because oxygen wants electrons and takes them from hydrogen to form water.

Answer: 2.17 g of  bromide product would be formed

Explanation:

The reaction of calcium bromide with lithium oxide will be:

[tex]CaBr_2+Li_2O\rightarrow 2LiBr+CaO[/tex]

To calculate the moles :

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

[tex]\text{Moles of calcium bromide}=\frac{2.5g}{199.9g/mol}=0.0125moles[/tex]

As lithium oxide is in excess, calcium bromide is the limiting reagent.

According to stoichiometry :

1 mole of [tex]CaBr_2[/tex] produce = 2 moles of [tex]LiBr[/tex]

Thus 0.0125 moles of [tex]CaBr_2[/tex] will require=[tex]\frac{2}{1}\times 0.0125=0.025moles[/tex]  of [tex]NH_3[/tex]

Mass of [tex]LiBr=moles\times {\text {Molar mass}}=0.025moles\times 86.8g/mol=2.17g[/tex]

Thus 2.17 g of  bromide product would be formed

Answer: skeleton equation

Explanation:

Answer:

Non-metals tend to gain electrons to attain Noble Gas configurations. The have relatively high Electron affinities and high Ionization energies. Metals tend to lose electrons and non-metals tend to gain electrons, so in reactions involving these two groups, there is electron transfer from the metal to the non-metal.

Answer:

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Explanation:

How does the concept of conservation of mass apply to chemical reactions? the reactants and products have exactly the same atoms. the reactants and products have exactly the same molecules. the change in the amount of matter is equal to the change in energy.
