Answer:
SO3
Explanation:
Data obtained from the question include:
S = 40%
O = 59%
To obtain the empirical formula, do the following:
Divide the above by their molar mass as shown below:
S = 40/32 = 1.25
O = 59/16 = 3.69
Next, divide by the smallest as shown below:
S = 1.25/125 = 1
O = 3.69/1.25 = 3
Therefore, the empirical formula is SO3
Answer:
The two products that will be formed are:
Ca(NO3)2
NaI
Explanation:
When NaNO3 reacts with CaI2, double substitution reaction takes place.
This means that I2 and NO3 will each substitute the other.
The chemical reaction used to explain this is as follows:
2NaNO3 + CaI2 .........> 2NaI + Ca(NO3)2
Hope this helps :)
The water levels would lower, because as the moon gets farther away, it's gravitational pull decreases. Hope this helps! :)
Answer:
A. is not
B. incorrect
C. identify substances that have the measured molecular mass
Explanation:
Since in the question it is mentioned that the Christy who is a forensic scientist and she gave a white powder and identify whether it is a sugar or not when she tested she seen that the molecular mass is different as compared with the sugar
So here it can be concluded that the white powder does not show a sugar that means it is not a sugar so automatically the hypothesis of Christy is wrong. And, the next step is to track the substance that shows the molecular mass i.e. measured
Answer:
IRON
Explanation:
I written down the work (I don't know how to paste photos) but i believ the answer is iron
