Answer:
0.0894 M
Explanation:
So you first want to change the grams into moles (since molarity is moles solute per Liter solution).
The molar mass of NaNO3 is 84.995 g/mol, so we divide 0.38g of NaNO3 by 84.995 g/mol to get approximately 0.004471 mol NaNO3.
Now, all you have to do is to divide by the total Liters of water (your solution).
Since the volume is expressed in mL, you just need to divide by 1000 (1 L = 1000mL) to get 0.050 L solution.
Therefore, to get molarity, you divide 0.004471 mol by 0.050 L to get your answer of 0.0894 M.
Answer: propanal and propanoic acid
Explanation: first of all Oxidation of alcohol with mild oxidizing reagent PCC gives Carbonyl compounds and with strong oxidizing agent like CrO3 and kmno4 gives carboxylic acids.
And primary alcohol gives Aldehyde with mild oxidizing reagent and carboxylic acids with strong oxidizing agent.
And ketone is formed with secondary alcohol by both mild and strong Oxidizing agent.
Here our compound is primary alcohol hence we will get propanal and propanoic acid depending on type of Oxidizing agent
False because when a substance changes from one state of matter to another it is a physical change no matter how many states of matter it skips
Answer:
the chemical energy flows into the engines and the engines starts to work.When the engines work mechanical energy is generated as mechanical energy is obtained when there is movement
