Balance the below chemical equation, include state of matter if missing. aAgCl(w) + bNi(x) > cNiCl3(y) + dAg(z)
1- What is a?
2- What is b?
3- What is c?
4- What is d?
w, x, y & z are states of matter.
5- What is w?
6- What is x?
7- What is y?
8- What is z?
9- Classify the reaction:

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

: )

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
