Answer:
A change in speed and direction between atleast one of the objects
Explanation:
Based on the chemical equation, to balance the equation we use 2 as a coefficients of HCl on left hand side of reaction.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each entities are present in same amount on left side as well as on the right side of the chemical reaction.
Given chemical reaction is:
Zn + HCl → ZnCl₂ + H₂
Above reaction is not balanced equation as number of chlorine and hydrogen atoms are not same, so balanced equation will be:
Zn + 2HCl → ZnCl₂ + H₂
Hence we add 2 as a coefficient of HCl to balance the equation.

Energy is absorbed in the reaction
Answer:
He is referring to the chromosphere
Explanation:
The sensory neurons within the olfactory organ are stimulated by Chemicals in the air.
Sensory neurons are the neurons that take up the signal from the receptors to the Central Nervous system (CNS)
Olfactory organ is the organ which is capable to sense smell i.e. Olfaction.
The Chemicals present in the air stimulates the sensory neurons present withing the olfactory organ consisting of olfactory epithelium. The cilia present in the epithelium recognizes the chemical present.
The neurons form connections of neuron to the olfactory bulb.
It is a mass of tissue that is round in shape that comprises of several kinds of cells of neurons that are capable to sense smell. It is necessary to sense smell properly.
Odorants are the compound that consist of an odor which get detected by the sensory neurons to carry out olfaction. They activate olfactory receptors and send signals to olfactory bulb.
