Answer:
A channel in an ancient Martian "riverbed" wasn't carved by liquid water but was built by molten lava, according to a new study of surface features on Mars. ... On Earth, lava tubes form during sustained volcanic eruptions, when lava flowing through previously solidified masses leaves behind empty channels in the rock
Explanation:
The lava, itself (when liquid) is very much above the boiling point of water, so it is not wet with liquid water, so it's a no in that sense,' he writes. ... Lava does contain a lot of water, especially prior to eruption (when it's called magma), but also as it flows across the ground,' he explained.
Answer:
Less time is required when using the sponge method than with the sourdough method, and although the sponge method provides hints of the depth of flavor and texture that result from the sourdough method, these characteristics are not as pronounced as they are when using the sourdough method.
An <u>electron cloud</u> is often thought of as a region of space in which there I a high probability of finding an electron.
In an atom, there is a "cloud" around the nucleus that contains all of the electrons. This is the place with the highest chance of finding an electron.
Answer:
The calculated concentration of sodium thiosulphate solution will be less than the actual value.
Explanation:
When IO3^2- solution is added to KI solution, I2 gas is released ,then sulphuric acid is now added to facilitate reduction. In order to prevent the escape of iodine (I2) gas ,the solution must immediately be titrated with thiosulphate.
If the solution is not immediately titrated with thiosulphate, the concentration of iodine available in the system decreases. When this occurs, it will also cause a decrease in the amount of iodine available to react with thiosulphate thus decreasing the concentration of thiosulphate obtained from calculation
