Answer:
Convection currents are flowing fluid that is moving because there is a temperature or density difference within the material.
Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy.
i think so.
i learned this recently and my textbook says that neutrons and protons are in the nucleus and electrons orbit around the nucleus. :)
i hope i was able to help
I think it is c because food and clothing aren't technically chemicals however they do contain them so d is a possible answer but I think it is c
Answer:
2:8
Explanation:
The reaction equation is a given as:
2C₄H₁₀ + 130₂ → 8CO₂ + 10H₂O
From the reaction equation, the mole ratio is 2:8
Butane is C₄H₁₀
Carbon dioxide CO₂
From the reaction;
2 moles of butane will produce 8 moles of carbon dioxide
Answer:
The number of lines possible for SO2 is 3
Explanation:
The following Procedure should be followed when calculating the number of vibrational modes:-
- Identify if the given molecule is either linear or non-linear
- Calculate the number of atoms present in your molecule
- Place the value of n in the formula and solve.
SO2 is a non-linear molecule because it contains a lone pair which causes the molecule to bent in shape hence, The mathematical formula for calculating the number of non-linear molecule in a infrared region is (3n - 6) here n is the number of atoms in molecule.
hence for Sulphur Dioxide (SO2), n will be 3
<u> Therefore, The number of lines possible for SO2 is (3*3) - 6 = 3</u>
