A compound containing Na, C, and O is found to have 1.06 mol Na, 0.528 mol C, and 1.59 mol O. What is the empirical formula of t
dsp73

Answer:

So first understand that empirical formula refers to ratio of different atoms in lowest integer form.

To calculate this let's make mol C as our default ratio of 1* and divide everything by 0.528 mol.

Na 1.06/0.528 = 2.00757575758

C 0.528/0.528 = 1

O 1.59/0.528= 3.01136364

Na2CO3

It's sodium carbonate

A client who had injection sclerotherapy for varicose veins is advised to wear compression (support) stockings. what is most imp
Xelga [282]

Don the stockings before getting out of bed in the morning.


To prevent distention of the veins, stockings should be applied before the legs are placed in a dependent position. Stockings should be used preventively before the discomfort associated with venous pressure and edema occurs. Knee-high stockings should end 2 inches (5.1 cm) below the knee to avoid popliteal pressure, which limits venous return. Stockings apply uniform pressure. Elastic bandages may slip or develop wrinkles, creating uneven pressure and constriction; edema may result.

During photosynthesis, the energy used to pump protons comes from ___________, whereas in cellular respiration it comes from ___
Annette [7]

During photosynthesis, the energy used to pump protons comes from ______light_____, whereas in cellular respiration it comes from ______NADH/FADH₂_______.

<h3>What are the steps in photosynthesis?</h3>
  1. The first step in photosynthesis is the absorption of light by chlorophyll bound to chloroplast thylakoid proteins. The absorbed light energy is used to remove electrons from electron donors such as water to form oxygen.
  2. The electrons are then transferred to the primary electron acceptor, quinine (Q.). Electrons are further transferred from the primary electron acceptor to the final electron acceptor (usually NADP⁺).
  3. Proton transfer from the thylakoid lumen to the stroma via the F₀F₁ complex generates ATP from ADP and Pi.
  4. The NADP and ATP produced in steps 2 and 3 provide the energy, and the electrons power the process of reducing the carbon to a six-carbon sugar molecule.

The first three steps of photosynthesis, are directly dependent on light energy and are thus, called light reactions, while the reactions in the last step are independent of light and thus are termed dark reactions.
