The given information in the question is :
Frequency = 170 Hz
1 Hz = 
Frequency = 170
Wavelength given = 2 m
Speed is unknown which we need to calculate.
Speed can be calculated by using the formula : Speed = wavelength X frequency
By plugging the value of wavelength and frequency in the above formula we get :
Speed = 
Speed = 340
The balanced chemical reaction is written as:
Sb2S3 + 6HCl = 6SbCl<span>3 + 3H2S
We are given the amount of </span><span>antimony(III) sulfide to be used in the reaction. This is amount will be used for the calculations. We do as follows:
2.85 g Sb2S3 ( 1 mol / </span><span>339.715 g ) ( 6 mol SbCl3 / 1 mol Sb2S3 ) (</span> 228.13 g / mol ) = 11.48 g SbCl3
Answer:
2 moles of Substance B
Explanation:
Because 1 mole of any substance contains 6.02× 10²³ particles either atoms, molecules, ions or even electron(Avogardo Constant)
Therefore 12.04 × 10²³/ 6.02× 10²³ = 2 mole of Substance B
Answer:
The atoms of different elements have different numbers of protons and electrons.
Answer:
It would be known as a chemical reaction or a chemical compound.
