The reaction CFCl3 + UV Light -> CFCl2 + Cl does not need another reactant as with CFCl3 because the reaction itself is reactive to light. Note that there are reactions that are sensitive to light to form products and when this type of reaction are not exposed to light, no reaction occurs.
1) Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Solar radiation is the source of energy for evaporation.
2) Condensation is phase change process in which the water changes from a gas to a liquid, the vapor becomes a cloud.
3) Precipitation is falling of the condensed water vapor as rain, snow, fog drip.
The water cycle (hydrological cycle) is the continuous movement of water all around the Earth.
Answer:
True
Explanation:
The molecule CH20 contains two single bonds and one double bond.
Hi there in this question we have a cube that has a volume Of 187 ml. And we would like to know this volume and inches cute. Alright so first thing I want to do is to convert two cm cubed and I can do that quite easily because a militia leader and a centimeter cubed are the same. Okay so millimeter will cancel. So actually we have 187 cm cubed. Now we need to convert two inches. There are 2.54 centimeters in one inch. But we need this cube. So I am going to cube this step because that will give us centimeters cubes. So that centimeters cubed will cancel and it will give us an answer. They are in inches cubed. Alright so I did go ahead and just Cube this 2.54. You can do it as you're doing part of the calculation or do it separately. And I got 16.39 centimeters cubed. Okay so now it's just a matter of taking 187 And dividing it by 16.39 the centimeters cube will cancel And we'll have an answer in inches cubed. We want that answer in three significant digits because 187 had three. So that ends up being 11 0.4 inches cute. All right and that is our final answer. This Cube has a volume of 11.4" cute. Thank you so much for asking your question and I hope this was helpful
Answer:
metamorphic rock
Explanation:
Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. It forms when a quartz-rich sandstone is altered by the heat, pressure, and chemical activity of metamorphism. These conditions recrystallize the sand grains and the silica cement that binds them together.
