Covalent bonds and it is between the hydrogens (hydrogen bonds)
The rounded three digits for the given number is 2.46
<u>Explanation:</u>
Significant figures are the number of digits in a value which contributes to the degree of accuracy of the value while measuring
<u>Rules:</u>
- Digits which are not zero are always essential.
- Any zeros between two major digits are important.
- Only a final zero or trailing zeros are important in the decimal section
<u>Solution:</u>
- Given number- 2.45986
- Decimals- 5 digits
- Scientific Notation
-2.45986 × 10^0
- Applying the rules until rounding the 3 digits we get,
- The rounded three digits for the given number is 2.46

As waves reach the shore, the energy in front of the wave slows down due to friction with the shallow bottom. ... The wave breaks, and it usually does so in water depth that is 1.3 times the wave height.
X4O10Let molar mass of X be ymolar mass = 4y + 10 x 16 = 4y+160
so, moles = 85.2 / (4y+160)
Moles of oxygen = 10 x [85.2 / (4y+160) ]Mass of oxygen = 16 x 10 x [85.2 / (4y+160) ]which is 48.0
so, 48 = 16 x 10 x [85.2 / (4y+160) ]
Solve the equation to get y.
y = 31
