yeah the answer above is wrong,

Out of the four choices:

Which of these statements correctly compares probeware (such as an electronic temperature probe) to traditional analog tools (such as a liquid-based thermometer)?

A. Measurements by traditional analog tools are good to a larger number of significant figures.

B. Measurements by traditional analog tools are less prone to experimental error.

C. Probeware is typically very difficult to transport.

D. Probeware is useful for obtaining many measurements in rapid   succession.

B is wrong, I'd guess A or D. Hope this helps someone.

The results of rutherford's experiment, in which alpha particles were fired toward thin metal foils, were surprising because ___
Zanzabum

The results of Rutherford's experiment were surprising as most of the alpha particles went straight without any deflection

<h3>Rutherford's Gold Foil experiment:</h3>

During the experiment, Rutherford directed beams of alpha particles at the thin gold foil and observed the following things:

  • Most of the alpha particles passed straight without any deflection
  • Few alpha particles got deflected from their paths on small angles
  • Very few alpha particles got deflected from their paths on very large angles

<h3>Results of the experiment:</h3>
  • Most of the space inside an atom is empty
  • The center of the atom is occupied by a tiny positively charged dense body called a nucleus. Most of the mass of the atom is concentrated in the nucleus
  • The electrons revolve around the nucleus in circular orbits and are called planetary electrons

Thus, the results of the experiment were surprising due to the above-stated facts.

Determine the specific heat of a material if a 15 gram sample absorbs 75 J of heat as it is temperature increases from 15°C to 4
Roman55 [17]

Answer:

Cp=0.2\frac{J}{g\°C}

Explanation:

Hello,

In this case, the heat, mass, specific heat and temperature change are related by:

Q=mCp\Delta T

Thus, if we want to compute the specific heat we simply solve for it:

Cp=\frac{Q}{m\Delta T}=\frac{75J}{15g*(40-15)\°C}  \\\\Cp=0.2\frac{J}{g\°C}

Best regards.

How do hydrogen ions (h+) and chloride ions (cl–) get into the lumen of the stomach?
user100 [1]
In the stomach cell, the enzyme carbonic anhydrase converts one molecule of carbon dioxide and one molecule of water indirectly into a bicarbonate ion (HCO3-) and a hydrogen ion (H+). In the stomach ion exchange is used to move H+ ions out the cells and into the lumen of the stomach

Aqueous hydrochloric acid reacts with solid sodium hydroxide to produce aqueous sodium chloride and liquid water what is the ter
Lilit [14]

Answer:

1.63 g of H₂O is the theoretical yield

Explanation:

We determine the reactants for the reaction:

HCl, NaOH

We determine the products for the reaction:

H₂O, NaCl

The equation for this neutralization reaction is:

HCl (aq) + NaOH(aq) → NaCl(aq) + H₂O(l)

We use both masses, from both reactants to determine the limiting.

First, we convert the mass to moles.

3.3 g . 1mol / 36.45 g = 0.090 moles of HCl

6.6 g . 1mol / 40 g = 0.165 moles of NaOH

Ratio is 1:1, so for 0.165 moles of hydroxide I need the same amount of acid. I have 0.090 HCl so the acid is the limiting reagent.

Let's work with stoichiometry. Ratio is 1:1, again.

1 mol of acid can produce 1 mol of water

Therefore, 0.090 moles of acid must produce 0.090 moles of H₂O

We convert the moles to mass, to define the theoretical yield

0.090 mol . 18g / 1 mol = 1.63 g
