The leaves of plants primarily serve to photosynthesize and require water conducted by the root to do so.
Water conduction by the rootAs a leaf of a plant running low on supplies that the root is responsible for, what I will be needing is water.
Thus, I will have to send a text message to the root to supply me with water. The root will respond by asking its foot soldiers (the root hairs) to conduct water into the root.
Once water gets into the root, it enters special cells that are responsible for conducting water inside plants - the xylems. The root sends the water through the xylem and water travels from there to me - the leaf.
Once the water gets to me, I will use it in combination with inorganic carbon (carbon dioxide) to synthesize carbohydrates.

Based on the Law of Conservation of Mass, what's the minimum amount of Magnesium that will react with 32g of Oxygen to produce 80.6g of Magnesium Oxide?
mass before reaction = mass after reaction
Mg + O = MgO
Mg + 32 = 80.6
Mg = 80.6 - 32 = 48.6 (a)

How many grams of ammonium sulfate can be produced if 2500.0 g of H2SO4 react with excess NH3 according to the equation 2NH3(aq) + H2SO4(aq) → (NH4)2SO4(aq)? Calculate the percent yield if 3100 g (NH4)2SO4 were actually produced.
-Calculate the theoretical yield of ammonium sulfate.
-Calculate the percent yield for the associated question
-Write the unit for the theoretical yield (see related question)
If 2500 grams of H2SO4 react with excess NH3 according to the illustration, the amount of ammonium sulfate that can be produced would be 3,370.92 grams. If only 3100 grams of ammonium sulfate were produced, the percentage yield would be 91.96%.
Stoichiometric calculationsFrom the equation of the reaction:
2NH3(aq) + H2SO4(aq) → (NH4)2SO4(aq)
The mole ratio of H2SO4 and (NH4)2SO4 is 1:1
Mole of 2500 grams H2SO4 = 2500/98 = 25.51 moles
Equivalent mole of (NH4)2SO4 = 25.51 moles
Mass of 25.51 moles (NH4)2SO4 = 25.51 x 132.14 = 3,370.92 grams
If 3100 g of (NH4)2SO4 were actually produced, the percentage yield would be:
Percent yield = 3100/3370.92 x 100 = 91.96%

How do you figure out the number of protons in an atom?
How do you figure out the number of protons in an atom?
Answer:
Atomic number shows u the amount of protons there are in the atom
The protons are equal to the number of electrons
The group number tells you the number of electrons on the outer shell
(Sorry if u didn’t want the extra info but really it’s simple like magnesium has 12 so it has 12 protons/ 12 electrons)
Answer:
To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number:
1. number of protons = atomic number.
2. number of electrons = atomic number.
3.number of neutrons = mass number - atomic number.

Translate the world equation in skeleton equation and balance them
(I) Hydrogen+chlorine= Hydrochloric acid
(II) potassium+chloride= potassium chloride+oxygen
Answer:
The balanced equation is: H2 (g) +Cl2 (g) →2HCl (g)
Explanation:
Balancing chemical equation refers to balancing the stoichiometric coefficients on the reactants and products side. This must be done as the chemical equation obeys the law of conservation of mass and momentum.
The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation. The Law of conservation of mass governs the balancing of a chemical equation.
Given chemical equation
The balanced chemical equation for the hydrogen + chlorine -> Hydrogen Chloride.
H2 + Cl2 → 2HCl
The equation is balanced as on the reactants side there are two hydrogens present and the same on the products side. For chlorine as well the same thing goes two chlorine atoms on the reactants side and two on the products side.

2) What amount of pressure is felt when your science teacher sits on a seat of nails
which measures 9 in by 9 in? Your science teacher weighs 280 pounds.
Answer:
23936.5 N/m² or 23936.5 Pa
Explanation:
Unit conversion
inches to meters ⇒ × 0.0254pounds to kilograms ⇒ × 0.45Our dimensions
9 inches ⇒ 0.229 m280 pounds ⇒ 127.01 kgSolving
P = F/AP = mg/AP = 127.01 x 9.8 / 0.229 x 0.229P = 1244.698 / 0.052P = 23936.5 N/m² or 23936.5 PaDenzel has a flask containing a mixture of rocks, soil, iron filings and salt. He needs to separate the four components of the mixture. Create a method to successfully separate each of the components of the mixture. HINT: use their physical and/or chemical properties.
Answer:
Sift the mixture to separate the rock from the iron filings, soil and salt.
You can then use a magnet to separate the iron filings from the salt and soil.
Afterwards, you can pour water into the remaining salt- soil mixture. Salt will dissolve but the soil will remain at the bottom of the water.
If you want to separate the salt from the water, you can boil it till all the water evaporates. The only thing that'd be left in the pan is salt.

Scientists have observed that the average surface temperature of the Earth has been increasing. This increase has
affected the oceans. Glaciers and ice sheets melt, and water from this melting process becomes part of the oceans.
The increasing temperature of the Earth's surface also warms ocean waters. As a result, the volume of the oceans
expands. These two events affect sea level.
What would happen to sea level if the average surface temperature trend that was observed since the 1960s
continues?
A) Sea level will rise, then will suddenly fall.
B) Sea level will remain the same.
C) Sea level will continue to fall.
