Answer:
He realized he needs to have the upper body and lower body held in place and needed the buckle as far down beside the person's hip so it could hold the body properly
Explanation: ''I realized both the upper and lower body must be held securely in place with one strap across the chest and one across the hips,'' Mr. Bohlin once said. ''The belt also needed an immovable anchorage point for the buckle as far down beside the occupant's hip, so it could hold the body properly during a collision.
Answer:
See explaination
Explanation:
For a reversible reaction, the equilibrium constant for a backward reaction is reciprocal.
If the coefficients in a balanced equation are multiplied by a factor, n, the equilibrium expression is raised to the nth power.
K' = (K)^n
In the second reaction the value kf n is 2. The first reaction is multiplied by 2.

Enter an equation of a chemical reaction and click 'Balance'. The answer will appear below
Always use the upper case for the first character in the element name and the lower case for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - carbon monoxide
To enter an electron into a chemical equation use {-} or e
To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}.
Example: Fe{3+} + I{-} = Fe{2+} + I2
Substitute immutable groups in chemical compounds to avoid ambiguity.
For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced,
is the final temperature of the given solution.
<u>Explanation</u>:
When heat is absorbed during reaction enthalpy is positive. To calculate amount of heat absorbed by solution:
To calculate no of moles of molar mass is 158.034 g/mol:
Hence quantity of heat can be calculated as given:
As considered that heat capacity of pure water is same as of solution (means to heat 1 gm of water by 1 degree Celsius the energy required) =
Now it is considered that due to dissolvation, no heat loss occurs and final temperature can be calculated by using specific heat capacity:
The final temperature of the solution is .
Ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .
Ethers will not have a hydrogen atom attached to the oxygen atom as alcohols do. Because ether molecules can not form intermolecular hydrogen bonds, their boiling points are much shorter than those of alcohol with such a comparable mass.
Owing to the combination of intermolecular H-bonding in alcohols though not in ethers, alcohols possess higher boiling temperatures than isomeric ethers.
Therefore, ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .
