Hi there! Let's tackle this together.
The answer to the question is option A.
When fossil fuels mined from the ground are burned with fire and sometimes crude oil, it releases toxic fumes which cause global warming. The same toxic fumes that come from these fossil fuels come from plastic.
The answer is option A.
Answer:
Water vapor has mostly disappeared at colder elevations and its effect on weather turbulence.
Explanation:
Answer:
(c) They come apart or lose their shape
Explanation:
Heat and temperature disrupt the attractions of the groups in the side chains that give the protein its characteristic shape.
(a) and (b) are wrong. The proteins do not lose their amino acids or their sequence.
(d) is wrong. The amino acids do not change into fatty acids.
Answer : The mass of 
occupy 30.3 L under the same conditions will be, 24.9 grams.
Explanation :
First we have to calculate the moles of
Now we have to calculate the moles of in 30.3 L by using Avogadro's law.
Avogadro's law : It is defined as the volume of gas is directly proportional to the number of moles of gas at constant pressure and temperature.
or,
where,
= initial volume of gas = 6.21 L
= final volume of gas = 30.3 L
= initial moles of gas = 0.16 mol
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
Now we have to calculate the mass of
Molar mass of = 32 g/mol
Therefore, the mass of occupy 30.3 L under the same conditions will be, 24.9 grams.
The number of protons in an elemnet can be determined by looking at the atomic number of the periodic table. Typicaly it is on top of the chemical symbol.
