Answer:
Explanation:
In one of the process, energy is built up from scratch, in the other one, energy is liberated for use by an organism or body.
The first process deals with a metabolic reaction in which energy is liberated:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
In the above process, energy is liberated when glucose combines with oxygen. The waste products are carbon dioxide and water. This process liberates heat energy which can be used to do work.
In the reverse process:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This process stores energy in carbon chains as chemical energy. It is this energy that is released in the first process.
Therefore, we can see that the first process liberates energy and the reverse process stores energy.
Answer:
m = 1.3 Kg
Explanation:
according to Specific Heat Formula :
Q = mc∆T
when Q is the heat energy in Joules
m is the mass of water
C is the specific heat its unit J/kg∙K
∆T change in temperature (the final t - the initial t)
by substitution:
Q = 190000 g * 4.184 J/g∘C *78
Q = 62006880 J
when The combustion of 1.0 lb of oil provides 2.2×107J
So lb of oil when Q = 62006880 J = 2.8 Ib
and when 1lb=454g
So 2.8 Ib = 1271.2 g = 1.3 Kg
Answer: 6 mol Li
Explanation:
The first step is to balance the equation.
2Li+Cl₂⇒2LiCl
We would need our conversions to find the amount of moles of Li needed to produces 6 mol LiCl.
I think that the answer would be birds because they are very different depending on species
Answer:
2. Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.
3. Since the vast majority of an atom's mass is found its protons and neutrons, subtracting the number of protons (i.e. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom. In our example, this is: 14 (atomic mass) – 6 (number of protons) = 8 (number of neutrons).
