Chemistry
1 answer:
egoroff_w [7]2 years ago
7 0

<h3>⇒c =  \frac{f - 32}{1.8}</h3><h3>⇒c =  \frac{86 - 32}{1.8}</h3><h3>⇒c =  \frac{54}{1.8}</h3><h3>⇒c = 30</h3>

<em>Hence</em><em>,</em><em> </em><em>84</em><em>°</em><em>F</em><em> </em><em>is</em><em> </em><em>30</em><em>°</em><em>C</em><em> </em><em>in</em><em> </em><em>Celsius</em><em>.</em><em>.</em>

Does Monocercomonoides still meet the definition of a eukaryote? Why or why not?
KengaRu [80]

Answer:

Yes

Explanation:

They are a unique type of eukaryote because they lack an important organelle: mitochondria. Mitochondria are essential for producing cellular energy in most eukaryotic cells. However, due to its habitat, it is able to acquire energy from a process called  sulfur mobilization.

They are significant because they challenge the idea that eukaryotes need mitochondria to be classified as eukaryotic. However, they have other membrane-bound organelles such as a nucleus and Golgi apparatus, meaning they remain eukaryotic.

Research suggest they lost their mitochondria over time, rather than never having had them throughout their ancestry.

Because of all these reasons, they still meet the definition of a eukaryote.

Mechanical Advantage may be calculated using all of the following except ___.
kotegsom [21]
The only exception of calculating mechanical advantage is by multiplying resistance force by effort force. For example, in calculating the mechanical advantage of a lever, we consider its output and input forces. The equation would now be as follows:

Mechanical advantage = output force / input force

50 grams of acetic acid C2H4O2 are dissolved in 200 g of water. Calculate the weight % and mole fraction of the acetic acid in t
Len [333]
50g   of   C_2H_4O_2   in   200g    H_2O

so:

\frac{50}{200+50}+100\%= \frac{50*100}{250}\%=20\%

MW of acid = 2*C+4*H+2*O = 2*12+4*1+2*16=

=24+4+32=60g/mol

so:

\frac{50g}{60g/mol}\approx0.83moles

it means that

in 50g of acid there is \approx0.83moles of acid

MW of H_2O = 2*H+O=2*1+16=2+16=18g/mol

so:

\frac{200g}{18g/mol}\approx11.11moles

it means that:

in 200g of water there is \approx11.11moles of water

therefore:

\frac{0.83mol}{11.11mol+0.83mol}= \frac{0.83mol}{11.94mol}=0.069

So your answers are:

20\%

and the mole fraction is:

0.069

Unknown # 29
sveticcg [70]

Answer:

I think it's a sulphate ion, because when you add hydrochloric acid to it it produces bubbles and when you add barium chloride it then produces a white precipitate.its formula is SO4

I hope this helps
