<span>Mass of CH2 = 12 + 2 = 14 g/mol The number of CH2s there are. So since the total mass is 84.2 g/mol. The solution is 84.2/14 = 6.012 thus the answer is 6 There are 6(CH2) So the molecular formula is C6H12</span>

Hydrogen gas and oxygen gas react to produce water. Both of these gases are present in
bonufazy [111]

Water isn't being produced all around us because the hydrogen and oxygen are present in stable form.

<h3>How come water isn't being produced all around us?</h3>

Water molecule is produced when the unstable hydrogen reacts with unstable oxygen because they are very reactive. Due to their reactive nature, hydrogen and oxygen react with each other forming water molecule. So that's why we can say that water is not being produced around us due to stable form of hydrogen and oxygen.

So we can conclude that Water isn't being produced all around us because the hydrogen and oxygen are present in stable form.

14. A piece of titanium at 100.0°C was dropped into 50.0 g of water at 20.0°C. The final temperature of the system was 22.6°C. W
Gemiola [76]

Answer:

m_{Ti}=13.0g

Explanation:

Hello,

In this case, based on the given, we can infer that as titanium is hot and water cold, it cools down whereas the water is heated up, therefore, in terms of heat, we have that the heat lost by the titanium is gained by the water:

-Q_{Ti}=Q_{H_2O}

That in terms of mass, specific heat and temperatures is:

-m_{Ti}Cp_{Ti}(T_2-T_{Ti})=m_{H_2O}Cp_{H_2O}(T_2-T_{H_2O})

In such a way, for computing the mass of titanium, considering the heat capacity of water 4.18 J/g°C, we have:

m_{Ti}=\frac{m_{H_2O}Cp_{H_2O}(T_2-T_{H_2O})}{-Cp_{Ti}(T_2-T_{Ti})} \\\\m_{Ti}=\frac{50.0g*4.18\frac{J}{g\°C}(22.6-20.0)\°C}{-0.54\frac{J}{g\°C}*(22.6-100.0)\°C} \\\\m_{Ti}=13.0g

Regards.

Ymorist [56]

Answer:

most likely a microscope

Explanation:

Within optical microscopes, there are wide-field microscopes and confocal microscopes. Wide-field scopes include your basic light microscope, which has a lens or lenses to magnify visible light transmitted or reflected by a sample. They're good for looking at single layers of cells or thin tissues, Piston sai
