Answer:
227 mmHg
Explanation:
Ptotal= PCO2 +PAr+PO2+PHe
PHe= Ptotal-PCO2 -PAr-PO2
PHe= (770 mmHg)-(128 mmHg)-(232 mmHg)-(183 mmHg)
PHe=227 mmHg
Answer:
See the answer below
Explanation:
<em>Since the experiment is set out to determine the melting point of the white solid, after missing the melting point due to distraction, there are two possible solutions and both involves a repeat of the experiment.</em>
1. The first one is to allow the molten substance to solidify again and then repeat the experiment. This time around, a critical attention should be paid to be able to notice the melting point temperature once the temperature gets to 132 C.
2. The second solution would be discard the molten substance and repeat the experiment with the a new solid one. Similarly, critical attention should be paid once the temperature gets to 132 C since it is sure that the melting point lies within 132 and 138 C.
Answer:
Water has a chemical formula of H2O . In here, there are two hydrogen atoms and one oxygen atom, and so its mass will be 2+16=18 amu . There are two water molecules formed, and that means the total mass of the products is 18⋅2=36 amu .
Answer:
6KClO3 + 3H2SO4 → 2HClO4 + 4ClO2 + 3K2SO4 + 2H2O
Explanation:
It's a bit long because you will keep changing the coefficient to match both side.
