Answer:
158.5g Zn are produced
Explanation:
To solve this question we have to find the moles of Aluminium. With the moles of Aluminium and the balanced reaction we can find the moles of Zn and its mass as follows:
<em>Moles Al -Molar mass: 26.98g/mol</em>
43.6g Al* (1mol/26.98g) = 1.616 moles Al
<em>Moles Zn:</em>
1.616 moles Al * (3mol Zn / 2mol Al) =
2.424 moles Zn are produced
<em>Mass Zn -Molar mass: 65.38g/mol-</em>
2.424 moles Zn * (65.38g / mol) =
<h3>158.5g Zn are produced</h3>

Answer:
Increased atmospheric carbon dioxide will cause increased ocean surface temperatures.
Explanation:
Greenhouse gases of which CO2 is a typical example are known to cause a gradual and steady increase in the surface temperature of the earth by trapping infrared rays close to the surface of the earth.
As the surface temperature of the earth rises, the surface temperature of the oceans rises also leading to the tendency towards hurricanes.
Hurricanes are violent storms which are known to form near the equator over warm ocean waters.
Hence, increased atmospheric carbon dioxide will cause increased ocean surface temperature which in turn increases the chances of the occurrence of hurricanes.
Answer : The balanced redox reaction will be,
Explanation :
The given chemical equation is,
In the half reaction method, the number of atoms in each half reaction and number of electrons must be balanced.
The half reactions in the acidic medium are :
Reduction : 
......(1)
Oxidation : 
.......(2)
Now multiply the equation (2) by 4 and then added both equation, we get the balanced redox reaction.
Thus, the balanced redox reaction will be,
Explanation: When an object moves from its initial position, it acquires some energy. This energy is called kinetic energy, as it is governed by the motion of an object. ... Thus, it is concluded that kinetic energy is the energy an object has due to its motion.
