At body temperature, 2404 J is required to evaporate 1 g of water. After vigorous exercise, a person feels chilly because the body is giving up heat to evaporate perspiration. A typical person perspires 25 mL of water after 20 minutes of exercise. How much body heat is used to evaporate this water
Answer: - 1.45 kJ
Explanation:
Using q = m x C x (ΔT)
Given : m = 3.8 g , C = 0.900 J/g°C, = -(450-25)°C = -425°C (Since final temperature is less than the initial, the sign is negative)
q = (3.8 g) x (0.900 J/goC) x ( -425 °C)
= -1453.5 J
= -1.45 kJ
Note that negative sign of q indicates that this much heat is released, when the metal cools down.

NO LINKS PLEASE! Why does dye dropped into a cup of water eventually spread throughout the water?
A. The water has lattice vectors.
B. The water undergoes a phase transition.
C. The water particles and dye particles exhibit Brownian motion.
D. The water exerts pressure on the container.
Answer:
C
Explanation:
okay, you need to look at the structures of the particles of matter in the solid, liquid and gas.
particles in a solid are in fixed positions, where they can only vibrate in those positions ( take a look at ice, or rather, a brick)liquids have very small or rather, no spaces between them, but they can slide or rub against each other, like people in a really tight crowd I guessgas particles have very large spaces between them and they move randomly. these exibit what's called brownian motion.since water particles (and all other liquid particles) have negligible spacings and limited movement, that allows the dye particles to move from a region of high concentration to that of a low concentration. the aim for this is for the mixture/solution to reach an equilibrium, that is the mixture must get to a point where all regions have the same concentration of the dye.you can refer to your coursebooks :)

If you have a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2, what is the resulting temperature in K
The resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.
How to calculate temperature?The temperature of a given gas can be calculated by using the ideal gas law equation:
PV = nRT
Where;
P = pressure V = volume n = number of molesR = gas law constantT = temperatureno of moles of Cl2 = 76.33g ÷ 70.91g/mol = 1.08mol
2.35 × 1.2 = 1.08 × 0.0821 × T
2.82 = 0.088T
T = 2.82/0.088
T = 31.8K
Therefore, the resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.

O A. Saturated alkene
O B. Unsaturated alkane
O C. Unsaturated alkene
O D. Saturated alkane
Answer:
The answer is C
Explanation:
unsaturated hydrocarbons have multiple carbon bonds
Unsaturated alkene describes the molecule shown below as the atoms are attached by double bonds.
An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether it is solid,liquid , gas consists of atoms . Each atom has a nucleus which is contains protons and neutrons and shells in which the electrons revolve.
The protons are positively charged particles and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged particles and hence the atom as a whole is neutral particle and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not change the chemical properties of the substances.

How does a noncompetitive inhibitor decrease the rate of an enzyme-catalyzed reaction?.
Answer:
In fact, the inhibitor and substrate don't affect one another's binding to the enzyme at all. However, when the inhibitor is bound, the enzyme cannot catalyze its reaction to produce a product. Thus, noncompetitive inhibition acts by reducing the number of functional enzyme molecules that can carry out a reaction.
