Explanation:
A clasping handshake may be used as an analogy for an enzyme-catalyzed reaction because it represents the specific manner in which an enzyme ________. folds to form secondary and tertiary structures interacts with water binds substrate is denatured by low pH
A clasping handshake is similar to the way in which enzymes bind to substrates in enzyme-catalyzed reactions.
Enzymes are biological catalysts that speed up the rates of biological reactions by lowering the minimum energy required by reactants in order to arrive at products.
Enzymes are able to achieve this feat by substrate-enzyme binding. The substrate binds to the enzyme in its active site, becomes products, and the products are released from the active site of the enzyme. Thus, the enzyme is free for the binding of another substrate.

What results when oxygen reaches a burning splint?
Answer:
Hydrogen (H2) When a burning splint is introduced to a sample of pure hydrogen gas, it will burn with a popping sound. Oxygen (O2) When a smoldering splint is introduced to a sample of pure oxygen gas, the splint will reignite.
Answer:
The burning splinter makes hydrogen and oxygen react and you hear a pop sound.

1. How much energy is required to heat 32.5g of water from 34°C to 75°C?
Answer:
5.850 kJ (of heat energy)
Explanation:
What we need:
[] The mass of the material = m = 32.5g
[] The temperature change that occurs = ΔT = 43
() 75 - 34 = 43
[] The specific heat capacity of the material = c
() This is the amount of heat required to raise 1 gram of that substance by 1°C
() For water, this is 4.186Jg°C
The equation to use:
Q = m * c * ΔT
Q = 32.5 * 4.186 * 43
Q = 5849.935 J
Q = 5.850 kJ

Answer:
[tex]\boxed {\boxed {\sf 5569.85 \ Joules}}[/tex]
Explanation:
We are asked to find how much energy is required to heat a sample of water.
We will use the following equation:
[tex]q= mc \Delta T[/tex]
The mass of the water is 32.5 grams. The specific heat capacity of water is 4.18 Joules per gram degree Celsius.
The change in temperature is the difference between the final temperature and the initial temperature. The water's temperature is raised from 34 degrees Celsius to 75 degrees Celsius.
ΔT= final temp - inital tempΔT = 75 °C - 34 °C = 41 °CNow we know all three variables:
m= 32.5 g c= 4.18 J/g °C ΔT = 41 °CSubstitute the values into the formula.
[tex]q= (32.5 \ g)(4.18 \ J/g \textdegree C)(41 \ \textdegree C)[/tex]
Multiply the first 2 numbers together. The units of grams cancel.
[tex]q= 135.85 \ \ J/ \textdegree C(41 \ \textdegree C)[/tex]
Multiply again. This time, the units of degrees Celsius cancel.
[tex]q= 5569.85 \ J[/tex]
5,569.85 Joules of energy are required.
Which is one factor that adds to the greenhouse effect?
a decrease in the amount of dust in the atmosphere
a decrease in the amount of water on Earth’s surface
an increase in gases in the atmosphere that absorb heat
an increase in the amount of solar radiation that reflects into space
Answer:
C
Explanation:
Edge 2022 trust the process
Knowing about the greenhouse effect we have that what intensifies this effect is an increase in gases in the atmosphere that absorb heat.
What is the greenhouse effect?Greenhouse effect is a natural atmospheric phenomenon responsible for the maintenance of life on Earth. Without the presence of this phenomenon, the temperature on Earth would be very low, around -18ºC, which would make the development of living beings impossible.
Thus, the main cause of the greenhouse effect is industrialization. Due to this process, the burning of fossil fuels has intensified in recent centuries. The main products of the combustion reaction of these reagents are the gases mentioned above as the main ones for the greenhouse effect.

Explanation:
the electron pair geometry around the central iodine in I3- is
The electron pair geometry around the central iodine in I3- is trigonal bipyramidal.
The shapes of molecules is determined by the Valence Shell Electron Pair Repulsion theory (VSEPR). According to this theory, The shape of a molecule depends on the number of electron pairs that surround the valence shell of the central atom in the molecule.
In the structure I3-, the iodine is sp3d hybridized and has a bond angle of 180°. There are three iodine atoms. The central iodine atom is surrounded by two bond pairs and three lone pairs. The electron pair geometry around the central iodine in I3- is trigonal bipyramidal.

If an organic compound has a carbonyl group and a hydroxyl group, with the carbonyl group connected to two R groups, is it considered an alcohol or a ketone? Or can it have properties of both?
Answer:
A carboxyl group (COOH) is a functional group consisting of a carbonyl group (C=O) with a hydroxyl group (O-H) attached to the same carbon atom. Carboxyl groups have the formula -C(=O)OH, usually written as -COOH or CO2H.
Calculate the mass of iron formed when 299g of iron (ii) oxide is reduced by excess carbon monoxide
Answer:
Mass = 88.12 g
Explanation:
Given data:
Mass of iron oxide = 126 g
Mass of iron formed = ?
Solution:
Chemical equation:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Number of moles of iron oxide:
Number of moles = mass/molar mass
Number of moles = 126 g/ 159.69 g/mol
Number of moles = 0.789 mol
Now we will compare the moles of iron with iron oxide.
Fe₂O₃ : Fe
1 : 2
0.789 : 2/1×0.789 = 1.578 mol
Mass of iron:
Mass = number of moles ×molar mass
Mass = 1.578 mol × 55.84 g/mol
Mass = 88.12 g

Rock candy is composed of large sugar crystals, which are made of sugar molecules. Growing the crystals in water with food dyes makes colored crystals. A friend has a plan to make jewelry using rock candy and claims that the jewelry will look like and last as long as jewelry made from gemstones. Use evidence about the bonding in ionic and molecular compounds to evaluate this claim.
It is possible to form jewelry from rock candy that will look like and last as long as jewelry made from gemstones since the both materials contains a crystalline lattice.
Ionic bonding comprises of units cells of oppositely charged ions that come together to form a crystal lattice. Molecular compounds such as gemstones are also composed of unit cells which also give a well defined crystal lattice.
We must note that the strength of these materials come from the fact that all have a well defined crystal lattice in which particles are well ordered. It is possible to form jewelry from rock candy that will look like and last as long as jewelry made from gemstones since the both materials contains a crystalline lattice.

If you tum out all of the lights in a room and shine a green flashlight on to a red apple, what color will you see?
Answer:
black
Explanation:
In white light, a red apple absorbs all the colors (including green) of the spectrum except red, which it reflects.
A green filter absorbs all the colors of the spectrum except green, which is transmitted through the filter (and comes through as green light).
When the green light shines on a red apple, the red apple absorbs the green light.
Since there is no red light shining on the apple, there is no red light to reflect, so the apple appears black.
