When the teacher opened the bottle of ammonia, the particles spread out by diffusion through the air due to the random collision of particles.
B: Acids that’s the right answer
Answer:
rats. that's all i know of Just about everything except the mother hen if they are natural hatch. Even when you incubate them there are threats. The healthy chicks will mob the weak ones, the older chicks (even by a day) will pick on the younger ones. Temperature extremes will threaten them as they need warm, humid conditions with gradual drops in surrounding temps in the brooder box. Early disease is sometimes a problem and all chicks should be started on medicated chick feed for the first few weeks to prevent several digestive diseases. Even the water dispenser can be a threat as newly hatched chicks will immerse themselves in an open water container so care should be taken to supply water in a self feeding covered dish.
Explanation:
We know that molarity is equal to the moles of solute/liters of solution. In the problem, they tell us that there is 1 liter of solution, so we have to find how many moles of solute there are. Since they give us the amount of solute in grams, we can use the molar mass of CO₂ to find how many moles there are:
Carbon has a molar mass of 1<span>2.012 g/mol
</span>
Oxygen has a molar mass of 15.999 g/mol. Since there are 2 (which we can see from the subscript), we have to multiply this number by 2. (15.999)(2)=31.998 g/mol
We can find the total molar mass of CO₂ by adding these two numbers up:
12.012+31.998=44.01 g/mol
We can then use dimensional analysis to find how many moles there are:
100 g CO₂ (1 mol CO₂/44.01 g CO₂)
=2.27 moles of CO₂
Now that we have the moles of solute and liters of solution, we can plug them into our molarity equation:
<u>M</u>= 2.27 moles/ 1 liter
<u>M</u>= 2.27 moles/liter
I think so that hypothesis is for isotopes and atomic mass.
