The reaction for producing glucose in plants, called photosynthesis, is:

Chemistry
1 answer:
Firlakuza [10]3 years ago
8 0

Answer:

41.16 moles of H2O

Explanation:

Ratio for the products-reactants is 1:6, so 1 mol of glucose is produced when plants use 6 moles of water.

Then, let's make a rule of three:

1 mol of glucose is produce by using 6 moles of water

6.86 moles of glucose are produced by the use of (6 . 6.86)/1 = 41.16 moles of H2O

1. Calculate the energy change (q) of the surroundings (water) using the enthalpy equation
Rasek [7]

Answer:

Q1: 728.6 J.

Q2:

a) 668.8 J.

b) 0.3495 J/g°C.

Explanation:

<em>Q1: Calculate the energy change (q) of the surroundings (water) using the enthalpy equation:</em>

  • The amount of heat absorbed by water = Q = m.c.ΔT.

where, m is the mass of water (m = d x V = (1.0 g/mL)(24.9 mL) = 24.9 g).

c is the specific heat capacity of liquid water = 4.18 J/g°C.

ΔT is the temperature difference = (final T - initial T = 32.2°C - 25.2°C = 7.0°C).

<em>∴ The amount of heat absorbed by water = Q = m.c.ΔT</em> = (24.9 g)(4.18 J/g°C)(7.0°C) = 728.6 J.

<em>Q2:  Calculate the energy change (q) of the surroundings (water) using the enthalpy equation </em>

<em>qwater = m × c × ΔT.  </em>

<em>We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. calculate the specific heat of the metal. Use the data from your experiment for the unknown metal in your calculation.</em>

<em></em>

a) First part: the energy change (q) of the surroundings (water):

  • The amount of heat absorbed by water = Q = m.c.ΔT.

where, m is the mass of water (m = d x V = (1.0 g/mL)(25 mL) = 25 g).

c is the specific heat capacity of liquid water = 4.18 J/g°C.

ΔT is the temperature difference = (final T - initial T = 31.6°C - 25.2°C = 6.4°C).

<em>∴ The amount of heat absorbed by water = Q = m.c.ΔT</em> = (25 g)(4.18 J/g°C)(6.4°C) = <em>668.8 J.</em>

<em>b) second part:</em>

<em>Q water = Q unknown metal. </em>

<em>Q unknown metal =  - </em>668.8 J. (negative sign due to the heat is released from the metal to the surrounding water).

<em>Q unknown metal =  - </em>668.8 J = m.c.ΔT.

m = 27.776 g, c = ??? J/g°C, ΔT = (final T - initial T = 31.6°C - 100.5°C = - 68.9°C).

<em>- </em>668.8 J = m.c.ΔT = (27.776 g)(c)( - 68.9°C) = - 1914 c.

∴ c = (<em>- </em>668.8)/(- 1914) = 0.3495 J/g°C.

Why might a geologist ask an analytical chemist to help identify the minerals in a rock.
Stels [109]

A geologist would ask the analytical chemist to identify the rock's composition. Chemists gather data from afar and analyze matter back to earth.

<h3>Who is a geologist ?</h3>

A geologist is a scientist who focuses on the processes that shape terrestrial planets and the solid, liquid, and gaseous stuff that makes up Earth. Although training in physics, chemistry, biology, and other sciences are sometimes helpful, geologists typically pursue geology as their field of study. Geology includes a significant amount of field study (field work), even if many of its subdisciplines also involve laboratory and computer work.

Geologists look for natural resources like oil, gas, precious and base metals in the energy and mining industries. They are also in the vanguard of efforts to prevent and lessen the effects of natural disasters and hazards like earthquakes, volcanoes, tsunamis, and landslides.

shepuryov [24]

Answer:

51.88 grams

Explanation:

make it in ratio form

Al=27×2=54.

54:48

(54/102)×98

=51.88 grams

O=16×3=48

(48/102)×98

=46.12 grams

Question 2<br> What is 3 x 108 written in standard form?
andriy [413]

I think you meant 3.08*10x^{8}

If you want to do that then you it will be 308 , 000 , 000

or if you meant 3 x 108 then it would literally just be 3 multiplied by 108 = 324
