Chemistry
1 answer:
MariettaO [177]3 years ago
5 0
Viscosity is the thickness of a liquid, cause by the friction between the molecules in that liquid. A very high viscosity would result in a solid form and low would be a liquid. If a liquid as zero viscosity is only found in superfluids at there freezing points or lower. There are also two types of viscosity “dynamic” (which is measure in seconds, pascal seconds to be exact) and “kinematic” (which is measured in metre per second squared)

Fun fact they use viscosity to predict when volcanoes are going to erupt:)

Hope this helps I love sciencey stuff so if you need anymore help let me know!

ch4aika [34]
<span>  </span><span><span>Colored ions indicate the presence of a transition metal. Transition metals display colors because of their incompletely filled d orbitals. As the transition metal absorbs a particular wavelength of light to raise the electron orbital, it causes the light that passes through the solution to emit a color.</span></span>

Which elements are metalloids? Check all that apply.
Finger [1]
<h3>Answer:</h3>
  • Boron
  • Silicon
  • Tellurium
<h3>Explanation:</h3>
  • Elements in the periodic table are either metals, non-metals or metalloids.
  • Metals are elements that react by losing electron(s) to attain an octet configuration. They occupy groups I, II and III of the periodic table and the transition metals.
  • Non-metals, on the other hand, are elements that react by gaining electron(s) to attain a stable configuration. Examples include halogens and noble gases among others.
  • Metalloids are elements in the periodic table that have the properties of both metals and non-metals.
  • Other examples of metalloids are arsenic, tellurium, germanium and polonium.

PLEASE HELP!!!!!!
jeyben [28]

<u>Answer:</u> The correct option is 1 mole of acetic acid was required for 2 moles of sodium bicarbonate

<u>Explanation:</u>

We are given:

Average number of drops of sodium bicarbonate = 142

The chemical equation for the reaction of sodium bicarbonate and acetic acid in vinegar follows:

NaHCO_3+CH_3COOH\rightarrow CH_3COONa+H_2CO_3

From the stoichiometry of the reaction:

1 mole of sodium carbonate reacts with 1 mole of acetic acid in vinegar.

Hence, the correct option is 1 mole of acetic acid was required for 2 moles of sodium bicarbonate
