Answer:
The pH of the solution is 7, 52
Explanation:
The pH gives us an idea of the acidity or alkalinity of a solution. Is calculated:
pH = -log (H +)
pH= -log ( 3x10-8)= <em>7, 52</em>
Answer:
27g + 33g = 60g
18g + 24g = 42g
Explanation:
The law of conservation of mass states that no matter can be destroyed or created. Because of this, you are simply making both sides equal.
Answer:
The name of the two compounds will be:
A :2,2-dimethylbutane
B: 3-methylpentane
Explanation:
The compounds are the isomers of hexane as per the given molecular formula.
There is no unsaturation or no ring is present in the compound.
Constitutional isomers are the one which have different arrangement of chain.
The possible compounds are shown in the figure with the products of monochlorination of the two isomers.
Thus there are five possible isomers of hexane.
Explanation:
We leave a soda in the car overnight and the temperature dips to 25 °F. To see if it will freeze we have to convert the °F to °C.
T(°C) = ( T(°F) - 32 ) *5/9
T(°C) = (25 - 32) *5/9
T(°C) = -3.9 °C
Since -3.9 °C is a temperature greater than the freezing point (-4.5 °C) the soda won't freeze.
Answer: The soda won't freeze.
