Answer:
Newton's first law.
Explanation:
It is the same as law of inertia.
Answer:
Dalton's law is fulfilled, since the elements in each compound of the example are related to each other in different proportions forming two different compounds; so for case a) and b) you have 15.54% and 9.323% P respectively for each compounds, that are equivalent to 0.2912 g P for every g Cl and the other produced 0,1747 g P for every g Cl.
Explanation:
Dalton's Law ( law of multiple proportions):
When two or more elements combine to give more than one compound, a variable mass of one of them joins a fixed mass of the other, and the first is related to canonical and indistinct numbers.
a) for the compounds A:
⇒ 0.2912 g P / gCl * ( 35.45 g CL / mol CL) * ( mol Cl / mol PCl ) * ( mol PCl / 66.427 g PCl ) = 0.1554 g P / g PCl
⇒ % P = 0.1554 * 100 = 15.54 %
b) for the compunds B:
⇒ 0.1747 g P / g Cl * ( 35.45 g Cl / mol Cl ) * ( mol Cl / mol PCl ) * ( mol PCl / 66.427 g PCl ) = 0.09323 g P / g PCl
⇒ % P = 9.323 %
Answer:
percent composition for CO2 is 0.04%
Answer:
mountains
Explanation:
A mountain can be defined as a land-form that has characteristics of high elevation and high relief. Mountains rise above the land and rise to form a peak. It is because of the high elevations that the climates are cooler in the mountainous regions as compared to the sea level. The mountains are elevated, have relief, and have steepness and continuity.
