Answer: The new volume of the air in the syringe is 7.3 mL.
Explanation:
Given: 
= 2.0 mL, 
= 1.02 atm, 
= ?, 
= 1.27 atm, 
Formula used to calculate the new volume in syringe is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the new volume of the air in the syringe is 7.3 mL.
We call it a solid because it has the () and in s inside of it meaning solid
Answer
a ecuación química para la reacción es: Bicarbonato sódico + vinagre = Acetato de sodio + agua + dióxido de carbono NaHCO3 + CH3COOH => CH3COO-Na+ + H2O + CO2 De la anterior fórmula, puede calcularse que una cucharadita de vinagre produce aproximadamente 1'5 gr de CO2
It is important to have the correct bond angles of the different atoms and the shape of the molecule due to following reasons;
Among other properties the polarity of compounds mainly depend upon the shape and bond angles of that particular compound. For example, considering the molecule of water, we already know that it is a polar molecule with partially positive hydrogen atoms and partially negative oxygen atoms and acts as universal solvent. The bond angle in water is about 104.5° with a Bent geometry. Unlike carbon dioxide (CO₂) which has Linear structure with bond angle 180° and is non-polar in nature therefore, the bent geometry in water is responsible for the polarity.
Other properties which can also be predicted by predicting the bond angles along with molecular geometries are;
i) Magnetism
ii) Phase of matter
iii) Color
iv) Reactivity
v) Biological activities <em>e.t.c</em>
Yes and no because it's important for a citizen to have a grasp on chemistry but you do not need it to be a politician
