Answer:
According to Thompson's model, Every atom consists of a positively charged sphere of radius 10-- 10m in which entire mass and positive charge of the atom are uniformly distributed inside the sphere electrons are embedded like seeds in watermelon. According Rutherford entire poistive charge and mass of the atom are concentrated in a tiny central core of the atom which is called atomic nucleus contains. Size of nucleus = 10-- 15m. The nucleus contains protons and neutrons. Negatively charged electrons revolve around the nucleus in circular orbits.
Explanation:
Plants can adapt to their environment for example algae is soft and can survive being moved or broken this is perfect for living on top of water were animals often swim and shake the surface.
Answer:
Argument: It is not Safe
Further support to the argument is given below.
Explanation:
Solution:
Argument: It is not Safe
First of all, we all know the ideal gas law:
PV = nRT
And the Boyle's Law states that , if the pressure is increased then, volume will decrease. and if the volume is increased then pressure will decrease.
V is inversely proportional to Pressure of the gas.
So, in this case, Let's suppose we have toxic solution of methyl alcohol in the bottle which is tightly closed. It means pressure in the bottle is high, hence the volume is less.
If in this scenario someone, leave the bottle open in the laboratory and as it is given that the level of solution will drastically decrease. It means it is volatile in nature and is converted into gaseous form and we know now that the open bottle has now less pressure. Hence the volume of the gas will be higher and now it can spread to every corner of the laboratory. And it is very dangerous.
Coefficients need to be changed while balancing a chemical reaction beacuse subscript show how the molecule exists in nature
