The chemical reaction of SiCl2→ Si +Cl2 is
A decomposition reaction
<u><em>Explanation</em></u>
- <u>A decomposition reaction</u> is type of chemical reaction which involve breaking down a compound into smaller compounds or individual elements.
- <em>SiCl2→ Si +Cl2 is a decomposition reaction because SICl2 is broken down into Si and Cl2</em>
- Decomposition reaction often involve input of energy in form of heat to break down compounds
Wavelength = 434nm = 434 x 10⁻⁹m
planck's constant = <span>h= 6.626 x 10 ⁻³⁴ J
E =?
by using the formula;
E = hc /</span>λ
value for c is 3 x 10⁸ m/s
E = (6.626 x 10 ⁻³⁴ J)(3 x 10⁸ m/s) / 434 x 10⁻⁹m
E = 1.9878 x 10⁻²⁵ / 434 x 10⁻⁹m
E = 4.58 x 10⁻¹⁹ joules

Answer:
The ligand crosses the plasma membrane and binds to the receptor in the cytoplasm.
Answer:
<h2>1. precede emotional experience</h2><h2>2. occur at the same time</h2>
Explanation:
William James and Carl Lange gave a theory about a type of emotion is called a James-Lange theory. According to this theory, physiological arousal creates an emotional experience. According to this theory, physiological changes are the primary condition while emotion is felt when brain interacts with the information obtained from the body.
According to the Cannon-Bard theory, the emotional feeling occurs when the dorsal thalamus is stimulated. In this theory, physiological changes and emotional experiences take place at the same time.
