The compound that is a saturated hydrocarbon is CH3CH2OH. The answer is letter A. A saturated hydrocarbon has only one single bond between the carbon atoms. The compound that is an unsaturated hydrocarbon is CHCH. The answer is letter D.
Answer:
CO is a chemical formula that contains one carbon atom (C) and one atom of oxygen (O). Altogether, CO translates to "carbon monoxide."
Explanation: Why monoxide and not dioxide? Well, the prefix mono means "one," and di means "two." Since there is only one oxygen atom (-oxide), then it must be monoxide! Voila!!
b. photon
c. electron
d. It depends on what the element is.
An atom with two protons, three neutrons and two electrons would have a mass of about how many atomic mass units?
a. 2
b. 3
c. 5
d. 7
Answer:
2. Orbital notation shows the spin of the electrons.
Explanation:
Answer:
Ka = 1.5 -10^-5
Explanation:
Step 1: Data given
Molarity of the solution = 0.25 M
pH = 2.71
Step 2 The equation
C3H7COOH + NaOH ⇆ C3H7COONa + H2O
Step 3: Calculate pKa
pH = (pKa-log[acid])/2
2pH = pKa -log[acid]
pKa = 2pH +log[acid]
⇒with pH = 2.71
⇒with log[acid] = -0.60
pKa=2*2.71 -0.60
pKa = 5.42 - 0.60
pKa = 4.82
Step 4: Calculate Ka
pKa = -log(Ka)
Ka = 10^-4.82
Ka = 1.5 -10^-5
Answer: The percentage by mass of carbon in the given compound is 45.8 %
Explanation:
We are given a chemical compound having chemical formula
To calculate the percentage composition of an element in a compound, we use the equation:
In 1 mole of given compound, 10 moles of carbon atoms are there.
Mass of
Mass of carbon element =
Putting values in above equation, we get:
Hence, percentage of carbon in given compound is 45.8 %.
