Answer:
The last option - slippery.
Explanation:
In general acids react with a metal to produce hydrogen.
Acids taste sour.
Acids turn blue litmus paper red.
Basic solutions can feel slippery.
<span>Percent yield offers how much of the expected quantity is created. Percent yield is actual yield divided by theoretical yield.
Theoretical yield comes from stoichiometry whereas actual yield comes from lab results.
Percent yield can be lower than 100% when some of the initial quantity is not fully reacted, or if say some of the sodium chloride in a water solution is boiled off with the water.
Percent yield can be greater than 100% if there are impurities in the yield. That is, an impurity that remains in the final compound can add to the weight and give you over 100% yield.</span>
<span>Chemical change would be happening. Colorless is a physical property on its own, Determining change to requirements you have to compare two things. Is this a physical property or is this a Chemical change and color in itself would represent a change in chemical properties to the aqueous salt solutions.</span>
No it does noot evaporate faster than sugar in water
Unit ppm stands for parts per million. in terms of mass, ppm is equivalent to mg/kg.
since 1 kg is 10⁻⁶ mg, 1 kg is equivalent to million mg.
therefore mg/kg is also ppm.
there are 1.3 g of Ca ions in 3100 kg
if 3100 kg contains - 1.3 g of Ca
then 1 kg contains - 1.3 g / 3100 kg
then Ca ions - 0.42 x 10⁻³ g/kg
Ca ion concentration - 0.42 mg/kg
therefore Ca ion concentration is 0.42 ppm
