Colt1911 [192]3 years ago
7 0

Answer:

hardness-Hardness is the ability of a material to resist deformation

luster-the way light interacts with the surface of a crystal

color-the quality of an object or substance with respect to light reflected by the object

streak- the color of the powder produced when it is dragged across an un-weathered surface.

specif gravity-the density of that object divided by the density of water cleavage -the tendency of a mineral to break along smooth planes

fracture-any separation in a geologic formation

tenacity-refers to a mineral's toughness or resistance to breaking or being deformed.

lol sorry that took awhile

Hydrogen and chlorine gases react to form HCl. You and a friend are on opposite sides of a long hallway, you with H2 and your fr
natali 33 [55]

Answer: It is true that Your friend should release the Cl_{2} first.

Explanation:

The velocity of particles of a gas is inversely proportional to the mass of gas. This means that more is the mass of gas less will be its velocity.

Or, more will be the mass of gas more slowly it will move from one place to another.

The molar mass of chlorine gas is more than the molar mass of hydrogen gas. Therefore, chlorine gas will move slowly.

So, your friend should release the Cl_{2} gas first and then according to the length of room you should release the H_{2} gas.

Thus, we can conclude that it is true that Your friend should release the Cl_{2} first.

In E. coli, the enzyme hexokinase catalyzes the reaction: Glucose + ATP → glucose 6-phosphate + ADP The equilibrium constant, Ke
kondor19780726 [428]

Answer:

Explanation:

Glucose + ATP → glucose 6-phosphate + ADP The equilibrium constant, Keq, is 7.8 x 102.

In the living E. coli cells,

[ATP] = 7.9 mM;

[ADP] = 1.04 mM,

[glucose] = 2 mM,

[glucose 6-phosphate] = 1 mM.

Determine if the reaction is at equilibrium. If the reaction is not at equilibrium, determine which side the reaction favors in living E. coli cells.

The reaction is given as

Glucose + ATP → glucose 6-phosphate + ADP

Now reaction quotient for given equation above is

q=\frac{[\text {glucose 6-phosphate}][ADP]}{[Glucose][ATP]}

q=\frac{(1mm)\times (1.04 mm)}{(7.9mm)\times (2mm)} \\\\=6.582\times 10^{-2}

so,

q ⇒ following this criteria the reaction will go towards the right direction ( that is forward reaction is favorable  until q = Keq
