Answer:
d) 44 g/mol
Explanation:
If we can consider that this gas behaves like an ideal gas, then we can use the following formula:
PV=nRT
P=pressure
V=volume
n=N° of moles
R= gas constant, it has multiple units, for this case, we will use 62.36 mmHg*Lt/mol*K
Then, the number of moles can also be noted as:
n=m/M , where m=mass and M=molar gas so: PV=(m/M)RT
M=(mRT)/(PV)
And we have the rest of the values for this case:
T=0°=273°K
V=1Lt
P=238 mmHg
m=0.614 g
If we finally put all these values in our formula, we can get the molar mass for this gas:
M=(0.614x62.36X273)/(273x1) gxmmHgxLtx°K/molx°K/(mmHgxLt)
M= 44 g/mol
Answer:
Tone is the author's attitude towards the topic. We can identify it by looking at the setting, characters, details, and word choices. By doing so, it will help us find meaning in the story or passage and help us feel more connected to the writing.
Bleach and anytype of cleaner like window cleaner or disinfectant is very dangerous because if you mix those two together it might cause a very deadly fume and can cause lung failure and death within about 5 hours
Answer: (c)
Explanation:
Nuclear fusion reactions involve 2 smaller nuclides combining to form one larger nuclide.
However, the mass is not correctly balanced for (a), but it is for (c).
