Explanation:
For water, the temperature needs to be a little over zero degrees Celsius (0C) for you to melt. If you were salt, sugar, or rock, your melting point is higher than that of water.
Answer:- 1337 g
Solution:- For mathematical operations we use PEMDAS. P stands for parenthesis off, E stands for exponents, M stands for multiplication, D stands for division, A stands for addition and S stands for subtraction. All the mathematical operations are done in this sequence.
What we have given in the problem is, 1210.0 g + 157.22 g - 30. g
Here we have addition and subtraction. As per the law, we will do addition first. In addition and subtraction we go with least number of decimal places.
1210.0 has one decimal place where as 157.22 has two decimal places, since the first number has least decimal places(one decimal place), the answer should also have only one decimal place.
1210.0 g + 157.22 g = 1367.2 g
Now, we will do subtraction. 30. does not have any decimal place and so on subtraction the final answer must not have any decimal places.
1367.2 g - 30. g = 1337 g
So, the final answer is 1337 g.
The compound formed will be X2Y3 with oxidation number of X = +3 and of Y = -2.
Example of X2Y3 type compounds are Fe2O3 and Mn2O3.
