Answer:
Please find the explanation of photosynthesis below
Explanation:
Photosynthesis is a metabolic process that occurs in the chloroplast of plants and algae. It involves the synthesis of food in form of glucose in the presence of sunlight. Photosynthesis occurs in two major stages namely: light dependent stage and light independent stage.
The overall chemical equation are as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
- Light dependent stage occurs in the thylakoid lumen of the chloroplast. In this stage, ATP and NADPH, which are energy carrier and electron acceptor respectively, are produced. They are then used in the light independent stage. This reaction strictly occurs only in the presence of sunlight.
- The light independent stage is also called Calvin cycle. The ATP and NADPH produced from earlier are used to synthesize glucose (C6H12O6) and oxygen (waste product) by combining CO2 and water (H2O).
Balance the equation by putting the correct number in front of each compound. You can work this out mathematically or by drawing pictures on a piece of paper like the videos.

If you build an atom with 6 protons, 7 neutrons, and 7 electrons, what element
have you created?
First off, you cannot "build" an atom because doing so would throw the Law of Conservation of Matter out the window, and we don't want to do that.
However, I get what you're asking... 6 protons, 7 electrons and 7 neutrons would make carbon-13.

A 20-milliliter sample of a gas is at 546 K and has a pressure of 6.0 atmospheres. If the temperature is changed to 273 K and the pressure to 2.0 atmospheres, the new volume of the gas
Answer: 30mL
Explanation:
A 20-milliliter sample of a gas is at 546 K and has a pressure of 6.0 atmospheres. If the temperature is changed to 273 K and the pressure to 2.0 atmospheres, the new volume of the gas is 30mL.
What is volume?Because gases occupy their containers, overall volume is identical to the container's internal volume. Liquids are typically measured using containers in which the volume or internal form of the container is indicated.
The volume of typical solid forms may be calculated using formulae. Another way to calculate the capacity of a solid would be to calculate how so much liquid something displaces.
P₁×V₁/T₁=P₂×V₂/T₂
substituting all the given values in the above equation, we get
6.0×20/ 546=2.0×V₂/ 273
V₂= 30mL
Therefore, 30mL is the final volume.

how many moles of sodium will react with water to produce 2.0 mol of hydrogen in the following reaction?
2Na(s) + 2H20(1) - 2NaOH(aq) + H2(g)
Answer: 4.0 moles of sodium will react with water to produce 2.0 mol of hydrogen
Explanation:
The balanced chemical equation is:
[tex]2Na(s)+2H_2O(l)\rightarrow 2NaOH(aq)+H_2(g)[/tex]
According to stoichiometry :
1 mole of [tex]H_2[/tex] is produced by = 2 moles of [tex]Na[/tex]
Thus 2.0 moles of [tex]H_2[/tex] are produced by =[tex]\frac{2}{1}\times 2.0=4.0moles[/tex] of [tex]Na[/tex]
Thus 4.0 moles of sodium will react with water to produce 2.0 mol of hydrogen

A mixture of PCl5(g), PCl3(g), and Cl2(g) is in a 1.00 L reaction vessel. The total pressure of the reaction system is 1.40 atm at equilibrium. Then the volume of the reaction vessel is reduced from 1.00 L to 0.50 L and equilibrium is re-established at constant temperature. What is the total pressure of the system at this point?
Answer:
The total pressure immediately after the volume reduction is 2.8 atmospheres
Explanation:
The question parameters are as follows;
The initial volume of the reaction vessel, V₁ = 1.00 L
The initial pressure of the reaction system, P₁ = 1.40 atm
The final volume of the reaction system, V₂ = 0.50 L
With the assumption that the gas mixture behaves as an ideal gas, and the temperature is constant, by Boyle's law we have;
P₁·V₁ = P₂·V₂
Where;
P₁ = The initial pressure in the reaction vessel
V₁ = The initial volume in the reaction vessel
P₂ = The total final pressure in the reaction vessel after the reduction in the vessel volume
V₂ = The final volume in the reaction vessel
∴ P₂ = P₁·V₁/V₂
From which we have;
P₂ = 1.40 atm × 1.00 L/(0.50 L) = 2.8 atm
The total final pressure in the reaction vessel, P₂ = 2.8 atm.
When a musician blows into a trumpet, a sound wave is formed that moves in the same direction as the musician's breath. This is an example of a
Answer:
Longitudinal wave
Explanation:
This is a longitudinal wave. Air is known to travel through a longitudinal wave. A wave is a disturbance that goes through a medium. As this musician blows into his trumpet, a vibration is formed, which moves in the direction as where the wave is coming from. Air moves in parallel direction as the wave
This is an example of a LONGITUDINAL WAVE.
A longitudinal wave is a type of wave that occurs when the vibration is parallel to the direction of the wave.The sound when it moves through the air compresses the gas (air) in the direction of travel of the wave.The air particles of a longitudinal wave vibrate in a parallel way to the direction of the wave propagation.In conclusion, this is an example of a LONGITUDINAL WAVE.

Can anyone explain dipoles in chemistry?
Answer:
See explanation
Explanation:
A dipole refers to a bond in which its two ends have opposite charges. A dipole results from a large difference in electronegativity between two atoms in a bond.
For instance, consider the bond between hydrogen and chlorine in HCl. The electronegativity of hydrogen is 2.2 while that of chlorine is 3.16. The significant electronegativity difference between the two atoms leads to a charge separation.
A partial positive charge appears on the atom that is less electronegative (hydrogen) while a negative charge appears on the more electronegative atom (chlorine).
This charge separation occurs because the shared electrons of the bond are more closely attracted to chlorine making it partially negative compared to hydrogen. A dipole moment now exists in the H-Cl bond hence the molecule is said to have a dipole.

Chemical analysis of a compound shows that it contains 0.99g lead ,0.154g sulfur and 0.306g oxygen. what is the empirical formula of the compound.
What is gas law?This can be solved by using one of the different gas laws. This is shown below:
PV / T
Given:
P1 = 0.98 atm
V1 = 212 cm^3
T1 = 293 K
P2 = ?
V2 = 196 cm^3
T2 = 308K
Substituting to the relation:
P1V1/T1 = P2V2/T2
(0.98 * 212)/293 = (P2 * 196)/308
P2 = 1.114 atm
For this we use general equation for gases. Our variables represent:
p- pressure
v-volume
t- temperature
P1V1/T1 = P2V2/T2
in this equation we know:
P1,V1 and T1, T2 and V2.
We have one equation and 1 unknown variable.
P2 = T2P1V1/T1V2 = 1.1atm
We know that when two lines cross each other forming four angles, such that, each pair of opposite angles are equal to each other. This pair of angles are known as Vertical opposite angles.
Similarly, ∠KML = ∠JML = 25°.
Therefore, Chemical analysis of a compound shows that it contains 0.99g lead ,0.154g sulfur and 0.306g oxygen. what is the empirical formula of the compound.
