Lady_Fox [76]3 years ago
7 0
1 mole = 6.022 * 10^23 formula units.

1.84*10^24 formula units CaCl₂ * (1 mole CaCl₂/6.022*10^23 formula units CaCl₂) = 3.06 moles of CaCl₂.

There are 3.06 moles of CaCl₂.

Pure research becomes ___ when scientists develop a hypothesis based on the data and try to solve a specific problem
Inessa05 [86]

Answer:

The answer is <u>applied research</u>

Explanation:

Pure research becomes <u>applied research</u> when scientists develop a hypothesis based on the data and try to solve a specific problem.

This is because the pure research try to understand, predict or explain the behavior of different phenomena <em>(the data)</em> while the applied research try to develop new technologies or methods (<em>hypothesis)</em> to take part, intervene and/or create changes on these phenomena and solve a <em>specific problem.</em>

Please help with 14-16 <br> Thank you!
Natalka [10]
I don't know about 14, but 15 is (4), because a liquid draws in heat to turn into a gas. 16 is (2), because to turn into a cold solid, something has to release heat.

Based on the relative energy of the absorbed electromagnetic radiation, which absorber, a peptide bond or an aromatic side chain
alina1380 [7]

Aromatic side chain exhibits an electronic excited state that is closer in energy to the ground state.

  • In order to respond to this query, we must decide whether a peptide bond or an aromatic side chain is demonstrating an electronic exited state that is more closely related to the ground state in terms of energy.
  • When our energy is as low as possible, we are in the ground state.
  • What I want to point out is that if we can choose between the two options—peptide bond or aromatic side chain—without knowing the specific reasons, we can immediately rule out two potential answers.
  • Consider what we already know about energy, we have:

                                 E = h x c/λ

  • That indicates that when we have more energy, a wavelength decreases. Lower energy corresponds to higher wavelength.
  • Aromatic side chains absorb between 250 and 290 nm, while peptide bonds do so between 190 and 250 nm.
  • According to our breakdown, we have an electron excited state that is more closely related to the ground state in terms of energy as wavelength increases.

Thus, Aromatic side chain exhibits an electronic excited state that is closer in energy to the ground state.

What would be the best flow rate of o2 for a patient with copd?
Step2247 [10]
When we say COPD, this means Chronic Obstructive Pulmonary Disorder. COPD includes a group of lung diseases which have progressed into a worse condition. One example of this is emphysema. In cases of COPD, they should be provided oxygen therapy and the best flow rate for patients with this disorder is <span>8-10 L/min, high-flow, via nasal prong. Hope this helps.</span>

How many moles of O2 molecules should be supplied to burn 1 mol of CH4 molecules in a domestic furnace?
Sati [7]
The combustion of 1 mole of methane (CH4) in a domestic furnace requires 2 moles of O2 molecules, assuming the combustion was complete or ideal. To solve this problem, use stoichiometry of the reaction's balanced chemical equation:

CH4 + 2O2 --> CO2 + 2H2O

The ratio of CH4 to O2 in terms of moles is 1:2. So 1 mole of CH4 needs 2 moles of O2.
