Explanation:
2Mg⁺ 2HNO₃ = Mg(NO₃)₂ + H₂
Answer:
the Molecular formula will be; C10H14O
Explanation:
Given the data in the question;
Chrysanthenone is an unsaturated ketone,
it has M+ = 150 and contains 2 double bond(s) and 2 ring(s).
molecular formula = ?
we know that ketone contain 1 oxygen and mass of oxygen is 16
so mass of the C and H remaining will be;
⇒ 150 - 16 = 134
Now we determine the number of C atoms;
⇒ 134 / 13 = 10
hydrocarbon with 10 hydrogen atom have CnH2n+2 means
⇒ ( 10 × 2 ) +2 = 22 hydrogens
But then we have 3 unsaturation meaning 6 hydrogens less and also we have ring meaning 2 more hydrogens
⇒ 22 - 6 - 2 = 14
Hence the Molecular formula will be; C10H14O
Explanation:
In order to find the molecular formula, we have to find the empirical formula first of all.
It is known that is a styrofoam, elements present are carbon and hydrogen atoms.
Element % Atomic mass Molar ratio Simple ratio
C 92.25 12.01 
= 7.68 
= 1
H 7.75 1.008 
= 7.68 = 1
As empirical formula of styrofoam is C_{x}H_{x}.
Hence, empirical mass = (12.01 + 1.008) g/mol = 13.018 g/mol = 13.0 g/mol (approx)
Molar mass given is 104 g/mol.
So, 
= 
= 8
Thus, we can conclude that molecular formula of the given styrene is 
.
Explanation:
Lead(II) phosphate is an ionic compound with chemical formula Pb3(PO4)2. Lead(II) phosphate is a long-lived electronically neutral reagent chemical.[1] Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA.[2] Lead(II) phosphate appears as hexagonal, colorless crystals or as a white powder. Lead(II) phosphate is insoluble in water and alcohol but soluble in Nitric acid (HNO3) and has fixed alkali hydroxides. When lead(II) phosphate is heated for decomposition it emits very toxic fumes containing Lead (Pb) and POx.[3]
Answer:
A wave with small amplitude.
Explanation:
Amplitude us inversely proportional to energy so the smaller the amplitude, the higher the energy.
Hope it helps.
