Answer:
There are seven (7).
Explanation:
Since 5 digits are not zero and they're before the zero, they're automatically sig figs.
Since there's a sig fig (#4) after the zero, zero and the # 4 are also sig figs.
Added together, they're are seven
Answer: It is possible. Chlorine reacts with potassium bromide to form potassium chloride and bromine.
When y equals 5, x is 104.3
When y equals 3 then x is 108.3
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
![y = 57.15 - 0.5x](https://tex.z-dn.net/?f=y%20%3D%2057.15%20-%200.5x)
<h3><u>If y equals 5 what is x ?</u></h3>
Substitute y = 5 in given expression
5 = 57.15 - 0.5(x)
5 = 57.15 - 0.5x
0.5x = 57.15 - 5
0.5x = 52.15
Divide both sides by 0.5
x = 104.3
Thus when y equals 5, x is 104.3
<h3><u>If y = 3 what is x ?</u></h3>
Substitute y = 3 in given expression
3 = 57.15 - 0.5(x)
3 = 57.15 - 0.5x
0.5x = 57.15 - 3
0.5x = 54.15
Divide both sides by 0.5
x = 108.3
Thus when y equals 3 then x is 108.3
V1 = 30L, P1 = 200mmHg, T1 = 10C
V2 = ??, P2 = 300mmHg, T2 = 25C
Use combined gas law:
P1V1/T1 = P2V2/T2
V2 = P1V1T2/P2T1
V2 = (200)(30)(25)/(300)(10)
V2 = 150,000/3,000 = 50 L
