What else can I help you with?
Which of the following is described by the equation h2o(s) heat -- h2o (I)?
The equation h2o(s) heat -> h2o (l) describes the process of solid water (ice) melting into liquid water.
C2H4 plus H2O equals?
The chemical equation for the reaction of C2H4 with H2O is C2H4 + H2O → C2H5OH (ethanol). This reaction results in the formation of ethanol by adding water across the carbon-carbon double bond in ethylene (C2H4).
What happens to the oxygen in lungs?
It leaves the body when it's exhaled. Before it is exhaled, some of the oxygen is absorbed through the membrane wall tissue, and into the bloodstream.
Cao plus h2o?
The reaction between CaO and H2O results in the formation of calcium hydroxide (Ca(OH)2) and heat. This process is known as hydration and is exothermic. Calcium hydroxide is a strong base and is commonly used in various applications such as in construction and agriculture.
Is H2O a compound or mixture?
H2o is a compound because it retains its own property.
Name 3 particles that are small enough to diffuse freely across the cell membrane?
H2O CO2 O2 hope this helps
Formulas for gas exchange?
Gas exchange in the lungs occurs through diffusion. Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli. The rate of diffusion is determined by factors such as the partial pressure differences of the gases, the surface area available for exchange, and the thickness of the respiratory membrane.
What are 2 substances that diffuse freely across a cell membrane?
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
What process is described by the equation H2O liquid gives H2O solid plus heat?
H2O(l) --> H2O(g) + heatshows the process of freezing.
What is Chemiosmosis and what is its role in cellular respiration?
movement of ions across a selectively-permeable membrane, down their electrochemical gradient. More specifically, it relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular respiration
What describes the equation H2O(I) H2O(s)?
This physical process is freezing.
What molecules move across during osmosis?
Water molecules are the primary molecules that move across during osmosis. Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration across a selectively permeable membrane.
What is the relation between osmosis and temperature?
Osmosis is a soluble (liquid) traveling through semi permeable membrane which is a wall that only allow certain cells and molecules through. So if temperature is low, kinetic energy is low and H2O molecules will slow down. While if temperature is higher, kinetic energy is more and H2O molecules will move faster thus the speed of the process of osmosis increases.
Why does water require channels to be transported across the membranes?
Water doesn't require channels to be transported across membranes because water is small enough to slip past the membrane; however, some cells do have channels, called aquaporins, which greatly increase the rate that water passes through the membrane.
What is the effect of osmosis on cell?
Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration across a semi-permeable membrane. In cells, osmosis helps regulate the balance of water and solutes, maintaining cell shape and function. Too much or too little water entering a cell through osmosis can lead to swelling or shrinking, potentially disrupting cellular processes.
What is a dry process?
One in which no water (H2O) is produced.
Which of the following is described by the equation h2o(s) heat -- h2o (I)?
The equation h2o(s) heat -> h2o (l) describes the process of solid water (ice) melting into liquid water.
