Answer:
ester
Explanation:
Carboxylic acids and alcohols react in the presence of strong acid to produce an ester and water. The two carbon chains come together, which is the condensation, and then water is generated, which is dehydration. The resulting compound is an ester.
1. a sulfur-32 atom contains 16 protons, 16 neutrons, and 16 electrons. what is the mass (in grams) of a sulfur-32 atom?
The mass in grams of a sulfur-32 atom is 32.
That is how the isotopes are identified, showing the mass number of the isotope, which is the sum of protons and neutrons: 16 protons + 16 neutrons = 32 mass number = mass in grams of the isotope.
2. the mass of a neutron is 1.67 x 10-24 g. approximately what number of neutrons would equal a mass of one gram?
divide 1 gram by the number of neutrons per gram:
number of neutrons = 1 g / 1.67 * 10 ^ - 24 g / neutrons = 0.5998 * 10 ^ 24 neutrons = 5.998 * 10 ^23 neutrons.
Assuming you are talking about the individual in space, Size and Weight changes in space due to the difference in gravity. Astronauts grow taller in space due to the micro-gravity they experience out of the earth's atmosphere.
It would not be:
Mass : Because mass is a measurement not dependent on gravity
Density : Astronauts do not blow out in bubbles once they leave the earth's atmosphere, therefore, we can deduct that density stays the same
The question is incomplete, complete question is;
Carbon monoxide replaces oxygen in oxygenated hemoglobin according to the reaction:
Use the reactions and associated equilibrium constants at body temperature to find the equilibrium constant for the above reaction.
Answer:
The equilibrium constant for the given reaction is 170.
Explanation:
![K_1=\frac{[HbO_2]}{[Hb][O_2]}](https://tex.z-dn.net/?f=K_1%3D%5Cfrac%7B%5BHbO_2%5D%7D%7B%5BHb%5D%5BO_2%5D%7D)
![[Hb]=\frac{[HbO_2]}{[K_1][O_2]}](https://tex.z-dn.net/?f=%5BHb%5D%3D%5Cfrac%7B%5BHbO_2%5D%7D%7B%5BK_1%5D%5BO_2%5D%7D)
..[1]
![K_2=\frac{[HbCO]}{[Hb][CO]}](https://tex.z-dn.net/?f=K_2%3D%5Cfrac%7B%5BHbCO%5D%7D%7B%5BHb%5D%5BCO%5D%7D)

![K_c=\frac{[HbCO][O_2]}{[HbO_2][CO]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BHbCO%5D%5BO_2%5D%7D%7B%5BHbO_2%5D%5BCO%5D%7D)
..[3]
Using [1] in [2]:
![K_2=\frac{[HbCO]}{\frac{[HbO_2]}{[K_1][O_2]}\times [CO]}](https://tex.z-dn.net/?f=K_2%3D%5Cfrac%7B%5BHbCO%5D%7D%7B%5Cfrac%7B%5BHbO_2%5D%7D%7B%5BK_1%5D%5BO_2%5D%7D%5Ctimes%20%5BCO%5D%7D)
![K_2=K_1\times \frac{[HbCO][O_2]}{[HbO_2][CO]}](https://tex.z-dn.net/?f=K_2%3DK_1%5Ctimes%20%5Cfrac%7B%5BHbCO%5D%5BO_2%5D%7D%7B%5BHbO_2%5D%5BCO%5D%7D)
( using [3])
The equilibrium constant for the given reaction is 170.
Answer:
All of these
Explanation:
In MnO:
mass of Mn = 55 g (as 1 mole of Mn weighs 55 g)
mass of O = 16 g (as 1 mole of O weighs 16 g)
The mass percent of metal Mn= 
In MnO2:
mass of Mn = 55 g
mass of O = 2*16 = 32 g
The mass percent of metal Mn=
In Mn2O3:
mass of Mn = 2*55 = 110 g
mass of O = 3*16 = 48 g
The mass percent of metal Mn=
In all the cases the mass percent of metal is greater than 50.
