Substituting this in to the angle 7x (which is equal to y), we get y= 84 degrees.
We also see that 24 + y + x = 180 since it is along a straight line. So 24 + 84 + z = 180 and then z = 72 degrees.

The currents in our experiment are between 0 and 20 nanoAmperes. How many electrons per second are passing an ammeter if it reads 10 nA
Answers
The number of electrons per second passing an ammeter if it reads 10 nA is 6.24 × 10⁹ electrons per second
Since our current reads 10 nA and we require the number of electrons per second passing through the ammeter, 10 nA = 1 × 10⁻⁹ C/s.
Since there are 1.602 × 10⁻¹⁹ C/electron, the number of electrons per second, n = current/electron charge
= 1 × 10⁻⁹ C/s ÷ 1.602 × 10⁻¹⁹ C/electron
= 1/1.602 × 10¹⁰ electrons
= 0.62422 × 10¹⁰ electrons per second
= 6.2422 × 10⁹ electrons per second
≅ 6.24 × 10⁹ electrons per second
So, the number of electrons per second passing an ammeter if it reads 10 nA is 6.24 × 10⁹ electrons per second

H2(g) + I2(g) → 2HI(g)
A student makes the following statements:
Hydrogen always has the same oxidation number, so it has an oxidation number of +1 in both the reactant H2 and product HI.
Iodine is in Group VIIA, so it has an oxidation number of –1 in both the reactant I2 and product HI.
Neither hydrogen nor iodine changes oxidation states, so the reaction is not a redox reaction.
In three to five sentences, describe the mistake that the student made, and determine whether or not the reaction is a redox reaction. Explain your answer.
Answers
The oxidation number of hydrogen increases to +1 while the oxidation number of iodine decreases to -1.
We must recall that the oxidation number of a particular atom or ion in any chemical specie is decided based on some arbitrary rules. Those rules are used to tell what the correct oxidation number of an atom should be in a compound or ion.
Firstly, the oxidation number of iodine and oxygen in the gas molecules is zero. The oxidation number of substances is not constant. However, on the right hand side, the oxidation number of hydrogen increases to +1 while the oxidation number of iodine decreases to -1.

After incubation of a set of O/F glucose tubes, the tube without mineral oil turned yellow, while the tube with mineral oil remained green. What does this indicate?
Answers
It might indicate NO fermentation and oxidation of glucose occurred. An oxidative organism breaks down glucose in presence of Oxygen, while a nonoxidative organism can break down glucose in absence of oxygen.
An Oxidation-Fermentation (OF)-glucose test is a microbiological test to determine how an organism is able to break down glucose.
In the first tube, a layer of mineral oil is added in order to reproduce anaerobic conditions, whereas this layer is not added to the second tube in order to reproduce aerobic conditions.
When the non-oil tube turns yellow, while the oil tube remains green, it means that the microorganism is oxidative (i.e., the microorganism only can metabolize glucose in presence of oxygen).
If both tubes remain green, it means that the test is negative and no fermentation/oxidation of glucose occurred.
If both tubes turn yellow, then the microorganism is oxidative and fermentative.

0.0624 g of a solid, diprotic acid, H2X, is neutralized with 13.96 mL of 0.1051 M NaOH. What is the molar mass of the diprotic acid, H2X
Answers
The molar mass of the diprotic acid, H₂X is 84.9 g/mol
We'll begin by calculating the number of mole in 13.96 mL of 0.1051 M NaOH. This can be obtained as follow:
Volume = 13.96 mL = 13.96 / 1000 = 0.01396 L
Molarity of NaOH = 0.1051 M
Mole of NaOH =?
Mole = Molarity x Volume
Mole of NaOH = 0.1051 × 0.01396
Mole of NaOH = 0.00147 mole Next, we shall determine the number of mole of the diprotic acid, H₂X required to react with 0.00147 mole of NaOH. This can be obtained as follow:H₂X + 2NaOH —> Na₂X + 2H₂O
From the balanced equation above,
2 moles of NaOH reacted with 1 mole of H₂X.
Therefore,
0.00147 mole of NaOH will react with = 0.00147 / 2 = 0.000735 mole of H₂X.
Finally, we shall determine the molar mass of H₂X.Mole of H₂X = 0.000735 mole
Mass of H₂X = 0.0624 g
Molar mass of H₂X =?Molar mass = mass / mole
Molar mass of H₂X = 0.0624 / 0.000735
Molar mass of H₂X = 84.9 g/molThus, the molar mass of the diprotic acid, H₂X is 84.9 g/mol

yes
no

Answers
It is not possible that a molecule that has absorbed infrared radiation subsequently emit a photon with a wavelength in the UV region as a result.
Both infrared rays and ultraviolet rays belong to the electromagnetic spectrum. However, the infrared rays are lower in energy than the ultraviolet rays. Hence, infrared rays have a longer wavelength than ultraviolet rays.
This implies that it is not possible that a molecule that has absorbed infrared radiation subsequently emit a photon with a wavelength in the UV region as a result.

empitical
take 100 gm of the compound
f O Divide by atomi wt of O to get moles
51.54/ 16.0 = 3.22
now if there is 1 atom of C and one of O, there will be 3 of H, so
CH3O is the empirical formula
the molar mass of the compound is 62-63. the mass of CH3O is
12 + 16 +3 = 31
