Can someone help me solve this problem? I have an exam the day after tomorrow, and this problem might come up. However, I'm completely desperate.
I always thought these signs got along great. Instead, we're having a huge fight. It started at the beginning of last year and ended with us finally breaking off contact in October 2022. How can that be?
Hello, I solved this problem like this, but I'm unsure about my solution. Can someone please check if I have the right solution. i) 1. 121.3 2. 121.3. 3. 253.7. 4. 106.3 ii) 1. sp^2. 2. sp^2. 3. sp^3. 4. Hybridization with d-orbital iii) C: 60%. H: 4.48%. O: 35.52% thanks in advance
Hello, I have a question. A concern, specifically. What would happen if you mixed two people? Could you please explain it to me? Or, in other words, what would happen if that were possible in real life? What would happen then?
Hey people, Could someone help me with this problem? The solutions are there, but I don't know how they came up with them.
The compression ratio (ε) of a diesel engine is 10 . The displacement volume is 1800 cm 3 . Calculate the compression volume of the diesel engine. Can anyone help? LG

Lava consists of many different substances that have different evaporation functions. Silicon dioxide evaporates, for example, at about 2200 °C.
absolutely correct! As a rule, sulphurous gases already vaporize from volcanoes which would be solid at lower temperatures. Since pure SiO2 has a relatively high solidus temperature, I would assume that other substances pass far earlier into the gaseous, important components of lava are usually Na+K+Ca and then Al and Si oxides, as well as Fe
I don’t know, but I don’t think lava can get gas. Probably she’d break up sometime.
If this reaction were transferred to the water, it would be possible to find out that water is freed at 0° C. and is liquid from 1° C. and evaporated from 100° C. Thus, the stone, which melts from about 1000° C., would have to evaporate from a temperature of about 100.000° C….
You can’t do that. Melting and boiling points of substances cannot be calculated, because they are related to complex things such as the molecular structure of the respective substance.
And water is not liquid from 1°C, but from 0°C.
Right!
And during evaporation, it is the same only at 100° C. For example, if you want to evaporate a liter of water in the pan, it begins to boil (theoretically) at exactly 100°C. The resulting steam is warmer. The liquid water in the pot remains at 100° C. all the time, although heat energy is continuously supplied.
So should I rather know that the water is freed from below 0°C and becomes liquid from above 0°C?
Whether water (each substance) is liquid, solid or gaseous at a certain temperature also depends on the ambient pressure. In the literature, normal pressure is always assumed.
At normal pressure, water is solid at below 0° C. and liquid at above 0° C.
Water at 0°C is at the Scheideweg whether it is freed or liquid, depending on how the environment affects the water …
