Carbohydrates which include sugars and starches are the primary energy sources produced in plants and used by heterotrophic organisms.
Carbohydrates are composed of a basic chemical formula that typically contains a ratio of one Carbon atom for every two Hydrogen atoms and one Oxygen atom C1H2O1. Basically one carbon atom for every one water molecule Carbon + Water = Carbohydrate.
Monosaccharides or Single Carbon Chain Sugars include Glucose C6H12O6
Disaccharides or Double Carbon Chain Sugars include Sucrose C12H22O11
Combining monosaccharides and disaccharides create Polysaccharides which are complex sugars called starches.
what happens when you combine hydroxide, chlorine, and 2 drops of h2o
Answer:
Chlorine will react in water to form hypochlorous acid, which can then dissociate into hydrogen and hypochlorite ions, according to Eqn (1). This reaction is very important, as the disinfecting power of HOCl, hypochlorous acid, is about 40–80 times that of OCl−, hypochlorite.Explanation:

Potassium hydrogen phthalate, KHP, is a monoprotic acid often used to standardize NaOH solutions. If 0.212 g of KHP are dissolved into 50.00 mL of water and titrated with 35.00 mL of NaOH, what is the molarity of NaOH. Molar mass of KHP
The molarity of the NaOH solution is 0.03 M
We'll begin by calculating the mole of the KHP
Mass = 0.212 g Molar mass = 204.22 g/mol Mole of KHP =?Mole = mass /molar mass
Mole of KHP = 0.212 / 204.22
Mole of KHP = 0.001 mole
Next, we shall determine the molarity of the KHP solution
Mole of KHP = 0.001 mole Volume = 50 mL = 50/1000 = 0.05 L Molarity of KHP =?Molarity = mole / Volume
Molarity of KHP = 0.001 / 0.05
Molarity of KHP = 0.02 M
Finally , we shall determine the molarity of the NaOH solution
KHP + NaOH —> NaPK + H₂O
From the balanced equation above,
The mole ratio of the acid, KHP (nA) = 1The mole ratio of base, NaOH (nB) = 1From the question given above, the following data were obtained:
Volume of acid, KHP (Va) = 50 mL Molarity of acid, KHP (Ma) = 0.02 M.Volume of base, NaOH (Vb) = 35 mL Molarity of base, NaOH (Mb) =?MaVa / MbVb = nA / nB
(0.02 × 50) / (Mb × 35) = 1
1 / (Mb × 35) = 1
Cross multiply
Mb × 35 = 1
Divide both side by 35
Mb = 1 / 35
Mb = 0.03 M
Thus, the molarity of the NaOH solution is 0.03 M

By titration, it is found that 73.3 mL of 0.175 M NaOH(aq) is needed to neutralize 25.0 mL of HCl(aq). Calculate the concentration of the HCl solution.
Answer:
0.5131M
Explanation:
NaOH(aq) + HCl(aq) — NaCl(aq) + H20(l)
Mole ratio of acid to base 1:1
(Ca × Va)/ (Cb × Vb) = Na/Nb
(0.175 × 73.3)/ (Cb × 25)= 1/1
12.8275= 25 × Cb
Cb= 12.8275/25
= 0.5131M
WILL GIVE BRAINLIEST (also pls don't copy answers from other ppl :D) Question: Choose two spheres of Earth which interact when hot springs are formed. Use complete sentences to explain how they interact during this process.
Answer:
Geosphere and Hydrosphere.
Explanation:
Hot springs are heated by geothermal heat—heat from the Earth's interior. In volcanic areas, water may come into contact with very hot rock heated by magma. The geosphere and hydrosphere interact when hot springs form. The geosphere gets a little melted by the hot hydrosphere and then when the springs shoot up in the air they break some rocks.

The molecule C2F4 has a trigonal planar molecular and electron pair geometry.
The shape of a molecule is dependent on the number of electron pairs that surround the central atom in the molecule. In the molecule C2F4, there are two central carbon atoms.
Each of the central carbon atoms have a trigonal planar molecular and electron pair geometry. C2F4 is a symmetrical molecule so it is nonpolar and has a zero dipole moment.

Equation for the incomplete combustion of methanol
Answer:
The basis for incomplete combustion is that instead of carbon dioxide being produced alongside water, carbon monoxide and carbon is produced instead, the carbon being released as soot. That handily sets the products up for the equation.
And combustion is simply a reaction between a fuel, in this case, methanol and oxygen.
The chemical formula for methanol is CH3OH. Simply write the reactants and products as a chemical equation and balance it, and you have the equation.

what is the molecular geometry of AsCl3?
Molecules' general shape, as well as bond lengths, bond angles, torsional angles, and any other geometrical factors that affect each atom's position, are revealed by their molecular geometry. The molecular geometry of AsCl₃ is trigonal pyramidal.
Molecule geometry is the study of the three-dimensional configuration of the atoms that make up a molecule. Because the shared pairs of electrons remain localized in a specific location between the nuclei of the involved atoms, covalent molecules have directed bonds.
The arsenic atom is surrounded by 4 regions of electron density which means that it has a steric number equal to 4. According to VSPER Theory, the molecular geometry will be trigonal pyramidal, AX₃E₁.

3 moles of nitrogen and 5 moles of hydrogen react to form ammonia. Use the balanced equation below to determine which is the limiting reactant.
N2 + 3H2 --> 2NH3
Answer:
H₂ is the limiting reactant
Explanation:
Balanced equations demonstrate the ratios of all reactants and products in terms of the number of atoms/molecules or moles;
In the given reaction:
1 mol of N₂ reacts with 3 mol of H₂ to produce 2 mol of NH₃
So the ratio of N₂ to H₂ to NH₃ will be 1:3:2
If we have 3 moles of N₂, we can apply the ratio to find that it will react with 9 moles of H₂ (3× the moles of N₂) to produce 6 moles of NH₃ (2× the moles of N₂);
Similarly, if we have 5 moles of H₂, then applying the ratio, we find that ⁵/₃ or 1.66... moles of N₂ (¹/₃× the moles of H₂) react with 5 moles of H₂ to produce ¹⁰/₃ or 3.33... moles of NH₃ (²/₃× the moles of H₂);
In order for all of the 3 moles of N₂ to react, it would require 6 moles of H₂;
There is only 5 moles of H₂ available, meaning there will be an excess of N₂;
5 moles of H₂ will react with 1.66... moles of the N₂, leaving 1.33... or ⁴/₃ moles of N₂ unreacted;
If the N₂ is in excess, then the H₂ is limited (i.e. the limiting reactant)

In times of hot, dry, weather, some cities ban the use of garden sprinklers. Why is there such a rule
Answer:
These weather conditions are consistent with droughts, often characterized by hot, dry, weather. When this is the case, it is important to conserve water and use it only for necessities. Garden sprinklers are not essential, so their use can be sacrificed in order to provide more crucial services, such as drinking water. This rule has been put in place in order to avoid water shortages and energy crises, events that would be even more damaging during an emergency.

Select True or False: Consider the reaction N2(g) 3H2(g) 2NH3(g). The production of ammonia is an exothermic reaction. When heat is added to the equilibrium system it will shift to increase the amount of ammonia produced.
Answer:
False
Explanation:
As I like to think of it, equilibrium will shift either 'forwards' (to increase products) or 'backwards' (to increase reactants) to oppose any change in system;
If heat is added, the equilibrium will shift in the direction that reduces heat within the system;
In other words, it will shift in favour of the endothermic reaction, i.e. the reaction where heat is gained by the molecules/atoms and therefore taken out from the system;
If the 'forwards' reaction, producing NH₃, is exothermic (i.e. energy is released in the reaction), then the 'backwards' reaction is endothermic;
So the equilibrium will shift in this direction, which is the reaction of 2 NH₃ molecules producing N₂ and 3 H₂
