Number of moles of Sn (l) produced when 4.0 moles of H2 (g) is completely consumed
Dafna11 [192]
The answer is 2.0 moles.
From their coefficients in the balanced chemical equation below for the reaction of tin dioxide with hydrogen gas to produce tin and water:
     SnO2(s) + 2H2(g) ==>Sn(l) + 2H2O(g)
two moles of hydrogen gas is to produce one mole of tin. We use this mole ratio to compute for the number of moles of tin as:
     moles of Sn = 4.0mol H2 (1mol Sn/2mol H2) = 2.0 mol

inn [45]

The lowest energy state an atom can be at is called its ground state. When an electron in an atom has absorbed energy it is said to be in an excited state. An excited atom is unstable and tends to rearrange itself to return to its lowest energy state. When this happens, the electrons lose some or all of the excess energy by emitting light. Light is only emitted at certain frequencies, each corresponding to a particular electronic transition within the allowed states.

electrons emitting light so the electrons will be in ground state

The distance between a carbon atom and an oxygen atom in the co molecule is how far from the carbon atom is the center of mass o
DENIUS [597]

The distance between a carbon atom and an oxygen atom in the co molecule is 0.63

<h3>What is the distance?</h3>

Distance is the measurement of the farness of two objects from each other.

The distance between the molecules can be calculated by the given formula

xcm = m_1+m_2m_1\times 1+m_2 \times 2

Putting the values in the equation

xcm = 12+1612 \times 0+16 \times 1.1 = 0.63 A^\circ

Thus, the distance between a carbon atom and an oxygen atom in the co molecule is 0.63
