What describes the equation H2O(I) H2O(s)?
This physical process is freezing.
Which of the following is described by the equation H2O l plus heat H2Og?
Evaporating -apex
Name a practical use fact of H2O with dissolved ions will freeze at a lower temperature than natural H2O?
This can be used as a lubricant or a coolant at a temperature below freezing of water, but above the freezing point of the liquid. Also, when ice freezes on sidewalks, salt is spread to prevent slipping on the ice.
Are icicles forming on the edge of the roof of physical or chemical change?
No it is not. The chemical composition is H2O before and after freezing.
What is the state called if water turns into ice?
If your're asking about the change of state, the answer would be Freezing. If you're asking about the state of ice, it would be solid.
Is the freezing of H2O a chemical or physical change?
Freezing of H2O is a Physical Change.
What process is described by the equation H2O liquid gives H2O solid plus heat?
H2O(l) --> H2O(g) + heatshows the process of freezing.
What describes the equation H2O(I) H2O(s)?
This physical process is freezing.
Is freezing h2o physical or chemical property?
physical, ice is still H2O
Which of the following is described by the equation H2O(s) heat H2O(l)?
freezing
What happens when freezing H2O and NaCl?
The freezing point of the solution depends on the NaCl concentration.
What phase changes is exothermic?
2 phase changes that are exothermic are condensing and freezing.
What is the freezing temperature of regular H2O?
it is 0 degrees but to optimize that you will have to do it lower
How do you get a freezing power like Emma on h2o just add water?
believe , close your eyes and imagine that your freezing it , and it takes practice
Why is the electrolysis water classified as a chemical change but the freezing of water is not?
Freezing is a phase transition and does not change the chemical makeup of H2O. (melting restores). Electrolysis changes the chemical structure of the water, decomposing the H2O into oxygen (O2) and hydrogen gas (H2).
Which of the following is described by the equation H2O l heat H2O g?
Evaporating (Apex)
Which of the following is described by the equation H2O l plus heat H2Og?
Evaporating -apex
