Answer:
To determine the rate law from a table, you must mathematically calculate how differences in molar concentrations of reactants affect the reaction rate to figure out the order of each reactant. Then, plug in values of the reaction rate and reactant concentrations to find the specific rate constant.

Changes to genes can affect the phenotypic traits of an organism, making them look differently.
Answer: -
4C₂H₅ + 13 O₂ → 8 CO₂ + 10 H₂O
Explanation: -
The given equation is
C₂H₅ + O₂ → CO₂ + H₂O
Balancing for H,
2C₂H₅ + O₂ → CO₂ + 5H₂O
Balancing for C
2C₂H₅ + O₂ → 4CO₂ + 5H₂O
Now right hand side we are getting 13 O which is an odd number.
In order to balance O, we first try to even out the number of O on right side by multiplying whole equation by 2.
4C₂H₅ + 2O₂ → 8CO₂ + 10H₂O
Now balancing for O
4C₂H₅ + 13 O₂ → 8 CO₂ + 10 H₂O
Answer:
Column 17 halogens
Explanation:
To answer the question we need to know the following;
What are valence electrons?
- Valence electrons are outermost electrons in the outermost energy level of an atom of any element.
What are halogens?
- Halogens are group 7 elements that have seven valence electrons. They include, chlorine, fluorine, iodine, etc
What is the reactivity of halogens?
- Halogens are the most reactive non-metals in the periodic table. They react by gaining one electron to attain a stable configuration.
<span>A flashlight is an electric-powered light source; the light source is a light bulb or an LED. The electrical energy is converted into visible light. Flashlights can be hand-held or mounted to a platform. Light from a lighting, on the other hand, is formed by exciting electrons to a higher state. </span>
