Taking into account the Brønsted-Lowry acid-base theory, the reaction between hypoiodous acid and water is:
HOI + H₂O ⇄ OI⁻ + H₃O⁺
Brønsted-Lowry acid-base theoryThe Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.
According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.
So, reactions between acids and bases are H⁺ proton transfer reactions, causing the acid to form its conjugate base and the base to form its conjugated acid by exchanging a proton.
Reaction between hypoiodous acid and waterIn this case, the reaction between hypoiodous acid and water is:
HOI + H₂O ⇄ OI⁻ + H₃O⁺
where HOI acts as an acid because it donates a potron, while water acts as a base because it accepts the proton donated by HOI.

Out of around 260,000 known species of angiosperms, approximately 195,000 are dicots. what percentage of angio sperms are dicots
Answer:
Explanation:
Formula
% = (dicots/angiosperms) * 100
Givens
angiosperms (total) = 260000
Dicots = 195000
Solution
% = (195000/260000) * 100
% = 0.75 * 100
Answer: % = 75% are dicots

▲ Two general chemistry students working together in the lab weigh out 0.832 g of CaCl2 2 H2O into a crucible. After heating the sample for a short time and allowing the crucible to cool, the students determine that the sample has a mass of 0.739 g. They then do a quick calculation. On the basis of this calculation, what should they do next? (a) Congratulate themselves on a job well done. (b) Assume the bottle of CaCl2 2 H2O was mislabeled; it actually contained something different. (c) Heat the crucible again, and then reweigh it.
After heating the crucible, cooling, and weighing the sample as 0.739 g, the students should have heated the crucible again and then reweigh the sample until a constant weight is obtained.
Drying samples with cruciblesThe sample being heated, CaCl2 2 H2O, contains water of hydration.
In order to arrive at an anhydrous sample of the salt, all the water molecules must be completely evaporated off by heating.
To do so, the sample should have been heated to constant weight by repeated heating and weighing until there is no longer a change in the weight of the sample.

What is the numbers of molecules for 65.8g of CO2?
Answer:
8.98*10^23 molecules CO2
Explanation:
The molar mass of CO2 is 44.0 grams/mol. If we convert 65.8 grams of CO2 into moles, 65.8g CO2 / 44.0g CO2 then we get about 1.49 moles of CO2. We know there are 6.02*10^23 molecules in a mole, so we would just multiply 1.49 mol CO2 * 6.02*10^23 = 8.98*10^23

Titanium is a transition metal used as pins and plates to support badly broken bones. Titanium is extracted from an ore that
contains the mineral titanium oxide. This oxide is converted into titanium chloride. Titanium chloride is heated with sodium to
form titanium metal. This reaction takes place in an atmosphere of a noble gas, such as argon
4Na(s) + TICIO
Ti(s) + 4NaCl(s)
Calculate the mass of titanium that can be extracted from 570 kg of titanium chloride.
Relative atomic masses:
CI 35.5
Ti 48
What is the Mass of titanium (g)
Using the stoichiometry of the balanced chemical reaction, the mass of the Ti is 144Kg.
What is a chemical reaction?The term chemical reaction refers to the combination of two or more substances to yiled one or more products.
The reaction equation here is; 4Na(s) + TICI4---->Ti(s) + 4NaCl(s)
Number of moles of TiCl4 = 570 * 10^3g/190 g/mol = 3000 moles
If 1 mole TiCl4 produces 1 mole of Ti
3000 moles of TiCl4 produces 300o moles of Ti
Mass of Ti produced = 3000 moles * 48 g/mol = 144Kg

given scientific reason for Nacl dissolves in water
Answer:
Matter is made-up of minute particles. Minute particles of matter have space between them.
So, when common salt is added to water, the particles of salt get into the space between particles of water.
Hence, common salt (Table salt) dissolves in water.

if you observe a first quarter on January 3 on what date will you see a full moon?
if you observe a first quarter on January 3, the date will you see a full moon is on February 1st.
What is the full moon about?The lunar phase during which the Moon is completely illuminated from Earth's perspective is known as the full moon. When Earth is situated halfway between the Sun and the Moon, this happens. This indicates that the near side of the moon, which faces Earth, is fully illuminated by the sun and appears as a roughly circular disk.
The Moon is a symbol for both the emotional and physical bodies. The full Moon is a time to be open and receive the spirit's light and awareness into your physical, emotional, and mental bodies

Which statement best predicts and explains the product of a single displacement reaction when the cation (A) with an oxidation number of +2 and an anion (B) with the oxidation number of -3 react and form a compound?
A+2B-3 is the predicted formula when each metal cation has a charge of +2 and each non metal has a charge of -3.
B2A3 is the final formula for the metal anion bonding to the non-metal cation in a 2:3 ratio.
A3B2 is the predicted formula with an overall charge of the compound being zero and each atom has 8 valence electrons in their outermost electron shell.
A3B2 is the predicted formula is made when each metal cation gains three electrons from the anion while each nonmetal loses 2 electrons to each of the cations.
The statement that best predicts and explains the product of a single displacement reaction is ; ( C ) A3B2 is the predicted formula with an overall charge of the compound being zero and each atom has 8 valence electrons in their outermost electron shell.
Octet stateGiven that the oxidation number is +2 shows that it will be an octet when it donates its 2 electrons. also for octet B it will become complete when it accepts 3 electrons. Therefore in order to balance out the octet of each atom is by cross multiplying to get A3B2.
Hence we can conclude that The statement that best predicts and explains the product of a single displacement reaction is ; A3B2 is the predicted formula with an overall charge of the compound being zero and each atom has 8 valence electrons in their outermost electron shell.
