The relevant chemical reaction can be written as:

In this reaction, carbon dioxide reacts with hydrogen to form methane and water. This reaction is known as the Sabatier reaction and is very commonly used to generate methane for fuel.

Using stoichiometry, along with the balanced chemical reaction (written above), 4 moles of hydrogen gas are used to produce 2 moles of water. 

or, 2 moles of hydrogen will produce 1 mole of water.

Thus, to produce 88.1 moles of water, 2 x 88.1 = 176.2 moles of hydrogen gas would be needed in the presence of excess carbon dioxide. Knowing this data, we can also calculate the mass of hydrogen gas needed. The molar mass of hydrogen gas (H_2) is 2 g/mole and hence a total of 352.4 grams of hydrogen gas are needed. 

Hope this helps! :3

The balanced equation for photosynthesis is shown below.
klio [65]
The true answer is: It's conserved because the total number of H atoms on each side is 12.
the first two answer is wrong because it's conserved not as mentioned, It's not conserved.

and the last one also wrong because the total number of O atoms are equal at the two sides but not equal 2.

Define a fluid very sort answer ​
Ganezh [65]

Answer:

A fluid is a medium that has a defined mass and volume, but no fixed shape, at a constant temperature and pressure. This may include gases, liquids, plasmas, and to some extent plastic solids. A fluid can flow and deform, preventing it from carrying loads in a static equilibrium.  A fluid is always compressible and internal frictional forces always occur due to the viscosity of the fluid.

What are the principles related to absolute, relative, carbon, or radioactive dating
stepladder [879]

The atoms of some chemical elements have different forms, called isotopes. These break down over time in a process scientists call radioactive decay. Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter. Each isotope is identified with what is called a ‘mass number’. When ‘parent’ uranium-238 decays, for example, it produces subatomic particles, energy and ‘daughter’ lead-206.
