Answer:
The Moon’s appearance changes during its orbit around Earth. These changes are called phases.
Explanation:
Answer:
~.1058 Moles
Explanation:
The formula for this question is the following.
1 mole of a compound/molar mass of the compound.
First we need to find the molar mass of H2O, which is the atomic mass on the periodic table. Hydrogen is 1.01, Oxygen is 16.00. Add those together to get the molar mass of the compound and you'll get an equation that looks like this.
1 mole of H2O/ 17.01 g/mol H2O
We now know that in 1 mole of H20 there is 17.01 g.
Take 1.8g and divide it by 17.01, you get your answer.

that the one kid thanks I we'll answer if 50 all ty
Answer:
Wavelength of the photon depends on transition from different states.
Explanation:
The wavelength of the photon that is emitted from the atom during the transition depends on the transition from different states. If the photon is emitted from n=4 state to n=3 state, the wavelength of photon is 1875 while on the other hand, if the photon is emitted from n=5 state to n=3 state, the wavelength of photon is 1282. If the photon is emitted from n=3 state to n=2 state, the wavelength of photon is 656.
Rock is a combination of two or more minerals, and it does not possess any specific chemical composition. It is present naturally in the environment. Some examples of rocks are limestone, granite, etc.,Limestone may contain minerals like calcite and aragonite. Each mineral has a specific chemical composition with a well defined crystalline structure.
Therefore, the correct option would be a. rock as rock is the naturally occurring solid mass made up of different types of minerals.
