Answer:
B. Keq = 6.0 x 10-2.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to remember that any equilibrium constant is computed by dividing the concentration of products by that of reactants:
![Keq=\frac{[Prod]}{[Reac]}](https://tex.z-dn.net/?f=Keq%3D%5Cfrac%7B%5BProd%5D%7D%7B%5BReac%5D%7D)
Thus, a reaction that is reactant-favored will have a Keq>1 because the concentration of reactants prevail over that of products at equilibrium, and thus, the correct answer is B. Keq = 6.0 x 10-2.
Regards!
Answer:
See attached picture!
Explanation:
There are two types of radioactive decay: alpha and beta.
Alpha decay removes a helium atom from the original element, causing the original mass number to decrease by 4 and the original atomic number to decrease by 2.
Beta decay removes an electron from the original element, causing the original mass number to remain the same and the original atomic number to increase by 1.
To solve your problems, you need to identify which decay is most likely to happen. You could do this by checking the possible answer choices. Usually, professors tell you which decay you are expected to write an equation of, but in this case, it's a matter of trial and error in order to get the answer.
Answer:
Q = 52668 J
Explanation:
Given data:
Amount of heat required = ?
Mass of water = 350 g
Initial temperature = 20°C
Final temperature = 56°C
Specific heat capacity of water = 4.18 J/g°C
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 56°C - 20°C
ΔT = 36°C
Q = 350 g× 4.18 J/g°C ×36°C
Q = 52668 J
Answer:
abiotic components are non-living chemical and physical factors in the environment which affect ecosystems. Biotic describes a living component of an ecosystem
Explanation:
C. It has mass and volume
Explanation:
Every atom of an element has mass and volume. Mass is the amount of substance it contains this is usually a function of their subatomic particles.
The bulk of the mass of an atom is concentrated in the nucleus where we have protons and neutrons. Electrons do not really add much to the mass of an atom.
Atoms also have specific volume.
- The reason for our selection is that atoms are the smallest particle of matter.
- Matter is anything that has weight and occupies space.
- Since it is matter, it must have specific weight and volume
