Answer:

long range order

Explanation:

A crystal consists of atoms, ions or molecules having both short range and long range order. The atoms, ions or molecules are arranged in a regular pattern throughout the lattice both at immediate vicinities and across the entire crystal structure.

This order accounts for the definite shape and unique properties of crystals which include their sharp melting and boiling points which distinguishes them from amorphous substances.

Answer:

long range order.

Explanation:

Crystals are atoms or molecules that are arranged in a manner which makes them repeats in a definite way(s). Crystals can form shape or structure such as hexagonal shape, monoclinic structure, cubic shape, tetragonal shape, orthorhombic shape and so on.

Long range order packing of crystals simply describe one of the properties of crystalline solids which is the regular repetition of a of certain arrangement pattern periodically.

Which statement about uncouplers is NOT true? A. They allow ATP synthesis with no electron transport. B. They allow electron tra
Arturiano [62]

Answer: the statement that is wrong about uncouplers is option A ( they allow ATP synthesis with no electron transport).

Explanation:

An uncoupler is a molecule that disrupts oxidative phosphorylation by dissociating the reactions of ATP synthesis from the electron transport chain. They allow electron transport without ATP synthesis. Their mechanism of action is basically to transport protons back into the matrix, preventing the required buildup of charge on the other side.

2,4-DNP is an example of an uncoupler.

Consider the generic reaction: 2 A(g) + B(g) → 2 C(g). If a flask initially contains 1.0 atm of A and 1.0 atm of B, what is the
irina1246 [14]

Answer:

b. 1.5 atm.

Explanation:

Hello!

In this case, since the undergoing chemical reaction suggests that two moles of A react with one moles of B to produce two moles of C, for the final pressure we can write:

P=P_A+P_B+P_C

Now, if we introduce the stoichiometry, and the change in the pressure x we can write:

P=1.0-2x+1.0-x+2x

Nevertheless, since the reaction goes to completion, all A is consumed and there is a leftover of B, and that consumed A is:

x=\frac{1.0atm}{2}=0.5atm

Thus, the final pressure is:

P=1.0-2(0.5)+1.0-(0.5)+2(0.5)\\\\P=1.5atm

Therefore the answer is b. 1.5 atm.

Best regards!
