The chemical equation is

Cu(s) +4HNO3(aq) ⇒ Cu(NO3)2(aq) + 2NO2(g) + 2H2O(g)

Answer:

Explanation:

In the right hand side of the equation, there are three compound which contains O2, which are;

Cu(NO3)2 , number of oxygen atoms =3*2 =6

2NO2, number of oxygen atoms = 2*2=4

2H2O, number of oxygen atoms =2*1=2

Total number of oxygen atoms on the right side of equation = 6+4+2 =12

Why have we not drilled or mined deeper into earth ??

alexdok [17]

<span>Scientists have determined that the center of the earth is 6371 km below the surface. But how has this been determined? Many people might answer that question by saying scientists can drill into the Earth with machines. However, the drilling rigs that scientists use can only drill about 20 km in the Earth which is not very deep! In other words, we can only drill into upper part of the crust of the earth. Extremely high temperatures and pressures within the Earth make drilling into it very difficult</span>

A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 745 mmHg. Express this pressur

aleksklad [387]

Answer : The pressure in torr and in atmospheres are, 745 torr and 0.980 atm respectively.

Explanation :

As we are given that the atmospheric pressure is, 745 mmHg.

Now we have to determine the pressure in torr and atm.

Conversions used:

1 atm = 760 mmHg

1 atm = 760 torr

1 mmHg = 1 torr

As, 760 mmHg = 1 atm

So, 745 mmHg = $\frac{745mmHg}{760mmHg}\times 1atm=0.980atm$

and,

As, 1 mmHg = 1 torr

So, 745 mmHg = 745 torr

Therefore, the pressure in torr and in atmospheres are, 745 torr and 0.980 atm respectively.
