Where is the graph , we can’t help without the photos
Answer:
proton :
a particale or atom containing a postive charge
nuutron
a particale or atom that contains a negative charge
electron :
a particale or atom with a negative chrage.
Explanation:
proton:
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.
nuetron:
a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
elcetron:
a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
Answer:
819 K
Explanation:
Given data
- Initial pressure (P₁): 1 atm (standard pressure)
- Initial volume (V₁): 250 mL
- Initial temperature (T₁): 273.15 K (standard temperature)
- Final pressure (P₂): 0.500 atm
- Final volume (V₂): 1500 mL
- Final temperature (T₂): ?
We can find the final temperature using the combined gas law.
Answer:
Explanation:
The decomposition of follows the equation
By definition, the rate of a chemical reaction can be expressed by
The rate of appearance of is related to the rate of disappearance of by the stoichiometry. This means that, for each mole of that appears 2 moles of are consumed. So
Urine color is the most effective method for measuring hydration status before and after exercise
Urine color is yellow color from a pigment called urochrome or urobilin. Darker pee contains less fluid, whereas lighter urine is more diluted. Dehydration may be indicated by very black urine. Don't worry if your urine doesn't match the color scheme.
Normal urine color is a pale yellow, however light amber is also acceptable. If your pee appears dark amber, you may be dehydrated and should drink additional water to compensate. Urine naturally contains yellow pigments known as urobilin or urochrome. The darker the pee, the more concentrated it is. Dehydration is the most common cause of dark urine color
