The IUPAC name of the oxyacid formed from chlorite is chlorous acid.
All oxyacids have the acidic hydrogen bound to an oxygen atom, so bond strength (length) is not a factor, as it is with binary nonmetal hydrides. Rather, the electronegativity of the central atom and the number of oxygen atoms determine oxyacid acidity. For oxyacids with the same central atom, acid strength increases with the number of oxygen atoms attached to it. With the same number of oxygen atoms attached to it, acid strength increases with increasing electronegativity of the central atom.
Compared to the salts of their deprotonated forms (a class of compounds known as the oxyanions), oxyacids are generally less stable, and many of them only exist formally as hypothetical species, or only exist in solution and cannot be isolated in pure form.
Thus, the IUPAC name of the oxyacid formed from chlorite is chlorous acid.

How do we think that Mars lost atmospheric gas?
What basic planetary property would have had to be different for Mars to retain a thicker atmosphere?
the rocky planet was exposed to harsh and forceful solar winds, which blew the Martian atmosphere away.
Another option for thickening the atmosphere of Mars, and, in turn, raising the temperature of the planet, would be to set up solar-powered, greenhouse-gas producing factories.

Mackenzie adds sodium chloride and sucrose to water. Identify the solutes.
a
sodium chloride
b
water
с
sodium chloride and sucrose
d
sucrose
The solute in this case would be sodium chloride and sucrose.
SolutesSolutes are substances capable of dissolving in solvents to give homogenous mixtures known as solutions.
In this case, both sodium chloride and sucrose were added to water - water is acting as the solvent.
Sodium chloride is soluble in water and so also is sucrose.
Thus, a homogenous mixture of sodium chloride and sucrose would result.

Select the correct answer. A mixture consists of glucose and water. What is the percent composition of glucose in the mixture if it contains 1. 3 moles of glucose (C6H12O6) and the total mass of the mixture is 276 grams? A. 17. 7% B. 26% C. 35% D. 77% E. 85%.
Answer:
The percent composition of glucose in the mixture is 85 % (Answer E)
Explanation:
"percent composition of glucose = (mass of glucose / mass of the mixture) x 100
Step 1: calculate the mass of glucose ( C6H12O6)
mass of glucose = moles of glucose x molar mass of glucose
molar mass of C6H12O6 = [( 12 x6) + ( 1 x12) + ( 16 x6)= 180 g/mol
mass is therefore= 1.3 moles x 180g/mol = 234 grams
Step 2: calculate the percent composition
= mass of glucose /mass of mixture x 100
= 234 g/276 g x 100 = 85 %(answer E)"
Answer: the answer is E

A student checks the air pressure in her bicycle tires early in the morning when it is cool outside. If she measures it again later in the day when it is hotter, what will she most likely observe? The pressure is the same. The pressure has increased. The pressure has decreased.
Answer:
answer in picture
Explanation:
When temperature increases, the air molecules gets energy. The air molecule starts moving randomly. The pressure is increased in the tire.
Define entropy?Entropy is defined as a measure of randomness or disorder of a system. disorder increases over time. Energy disperses.
In tire, it is filled with air molecules, its nothing but oxygen, nitrogen, sulpurdioxide, carbondioxide etc. when the outer side temperature increases, tire starts heating.
Heat is nothing but one type of energy, energy will transfer in to molecule. Molecule starts vibrating, hitting to walls this will increases the temperature and pressure increases.
Thus, if outer temperature increases. Pressure also increases.

Water moves up a plant because of hydrogen bonds by a process called __________.
Answer:
transpiration
Explanation:
Transpiration is when water moves up a plant stem, because water has surface tension due to cohesion.
In water, the H is slightly positive and the O2 are both slightly negative. This creates bonds between the H and O of another molecule. This causes water to be sticky, and when water moves up a plant, other molecules are also pulled up.

Explanation:
1. Which location (a, b, or c) would have the highest temperature?
2. Which location(a, b, or c) would have the lowest temperature?
3. Give reasoning to explain how and why the latitude of a place on Earth affects its average temperature.
WORTH 100 POINTS! WILL MARK BRIANLESIT
Answer:
1. B
2.C
3.The further out and the closer the the equator a place on Earth is the warmer it is due to the fact that the sun directly hits countries on the equator and takes in heat faster then the north and south pole. Countries on more of a curve are colder due to the fact they are more curved and it is harder for the heat to be taken in at a curve.
B is center point line passing through earth and it's placed right infront of sun so b would have highest temperature
#2
A and C both are poles so at a and c least sun light can reach hence lowest temperature.
#3
As far as the latitude is placed from equator lower the temperatureAs near as the latitude is located from equator higher the temperatureThe ph of water is approximately 7 which means it is:.
Answer: Neutral
Explanation: This is because, in the ph scale, greater than 7 indicates base or alkaline (basic), while less than 7 indicates that it is acidic.
Dispersed colloids systems have the same _________________ (on the particles) which keep the particles dispersed.
Answer:
The dispersed particles of lyophobic colloidal systems have the same kind of electric charge. Particles with like charge repel each other and their mutual repulsion prevents them from joining together and settling out. The accumulation of similar kind of charges on the suspended particles holds them part and thus stabilizes the system.

Answer:
C = q / m x dT
Explanation:
By definition, specific heat, C = heat absorbed, q divided by mass, m and change in temperature, dT
So C = q / m x dT
Answer:
The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C)
Formula:
energy (J) = mass (kg) * specific heat capacity (J/kg°C ) * change in temperature
required answer:
C = q / m * dTusing the formula:
C = [tex]\frac{102}{12.5*(55-22)}[/tex]
C = 0.2473 J/kg°C
↑
This is the specific heat capacity of copper
A compound containing only carbon and hydrogen is found to contain 80.0% carbon. It has a molecular weight of 30.0. What is its molecular formula
Answer:
(80.0, 20.0) The statement states that 80% of the compound is carbon. To acheive the amount of carbon in a 100 g sample, you need to multiply the weight of the sample by the percentage of carbon in the compound. Recall that 80%=80/100=.8 .8*100g=80g of carbon. The same process goes for the hydrogen. .2*100g=20g hydrogen. Explanation:

Thrust acts on the spacecraft and propels in the space.
How space shuttles move?1. The force created by the shuttle's engines in expelling the burning fuel produces an equal thrust in the opposite direction. This thrust acts on the spacecraft and propels in the space.
2. The thermosphere and the stratosphere are our hottest atmosphere layers because these two layers are present near the sun as compared to other layers of atmosphere.
3. When the meteors hit the atmosphere, meteors rub against air particles and create friction which is heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars.
