Answer:
B. Respiration
Explanation:
cellular respiration is the process where cells use glucose (C6H12O6) and oxygen gas (O2) to make carbon dioxide (CO2) water (H2O) and ATP, which is energy
formula:
C6H12O6 + 6O2 -> 6CO2 + 6H20 + 38ATP
Answer:
D
Explanation:
P4 is polyatomic molecule
Hi, thank you for posting your question here at Brainly.
The acid dissociation constant, Ka, is an equilibrium constant that measure the strength of an acid. It is a ratio of the concentration of the products (salt and water) and the reactants (acid). The higher the Ka, the more tendency it is to favor the product side, which means more tendency to donate H+ ions. This is exactly the definition of a strong acid (high H+ ionized).
Thus, the answer is letter D.
Answer:
0.062J
Explanation:
Given parameters:
Height of raising the spoon = 21cm
Mass of spoon = 30g
Unknown:
Gravitational potential energy = ?
Solution:
The gravitational potential energy of a body is the energy by virtue of the position of a such a body in space.
It is given as:
G. P. E = mgh
where m is the mass
g is the acceleration due to gravity
h is the height
Convert the parameters to appropriate units.
21cm to m gives 0.21m
30g to kg gives 0.03kg
G.P.E = 0.03 x 9.8 x 0.21 = 0.062J
