Answer:

$m_{Sn}=630.57gSn$

Explanation:

Hello!

In this case, according to the chemical reaction:

$SnO_2+2H_2\rightarrow Sn+2H_2O$

We can evidence the 2:1 mole ratio between hydrogen and tin, thus, we perform the following stoichiometric setup to obtain the mass of produced tin:

$m_{Sn}=21.46gH_2*\frac{1molH_2}{2.02gH_2}*\frac{1molSn}{2molH_2} *\frac{118.71gSn}{1molSn} \\\\m_{Sn}=630.57gSn$

Best regards!

What are alluvial diamond fields?

hammer [34]

Answer:

Alluvial diamond mining occurs in riverbeds and beaches, where thousands of years of erosion and natural forces such as wind, rain, and water currents wash diamonds from their primary deposits in kimberlite pipes to beaches and riverbeds. Some alluvial deposits are from long-ago rivers.

A compound, C4H6O, exhibits IR absorption at 1705 cm-1. Its carbon NMR shifts are given below. The number of hydrogens at each c

Airida [17]

Answer:

Methacrylaldehyde

Explanation:

The first step is the calculation of the <u>IHD</u> (index hydrogen deficiency):

$IHD=~\frac{2C+2+N-H-X}{2}$

$IHD=~\frac{2(2)+2-6}{2}=2$

This value indicates that we have <u>2 double bonds</u>. Now, if we check the IR info we can conclude that we have an <u>oxo group</u> (C=O) due to the signal in <u>1705 cm^-1 </u>. So, the options that we can have are <u>aldehyde or ketone</u>.

If we analyze the NMR info we have a signal in 194.7 <u>with only 1 hydrogen</u>. This indicates that necessary we have an <u>aldehyde due to the hydrogen</u>. Also, for the signal in 14 we will have a $CH_3$ , for the signal at 134.2 we will have a $CH_2$ and for the signal at 146.0 we will have a quaternary carbon (no hydrogens present).

So, we will have a $CH_3$ , $CH_2$ , C (without hydrogens), an aldehyde group and a double bond.

When we put all this together we will obtain the <u>Methacrylaldehyde</u> (see figure).

Which of these is MOST LIKELY to contribute to the long-term instability of a local ecosystem? A) storms that uproot large trees

Amanda [17]

The most damaging event is B) introduction of a non-native animal species.

There are multiple cases in recorded history where invasive species have ruined ecosystems and even driven some species to extinction. An example of this is the dodo bird which went extinct due partially due to the invasion of rats into their habitats.
