Answer:
A. Perchloric acid and potassium hydroxide
B. Trioxonitrate V acid and Cesium hydroxide
C. Hydroiodic acid and calcium hydroxide
Explanation:
An acid reacts with a base to form salt and water. The acid and the base that reacted for each of the compounds have been written in the answer above. The reaction equations are given below:
A. HClO4 (aq) + KOH (aq) ———> KClO4 (aq) + H2O (l)
B. HNO3 (aq) + CsOH (aq) ———-> CsNO3 (aq) + H2O (l)
C. 2HI (aq) + Ca(OH)2 (aq) ———> CaI2 (aq) + 2H2O (l)
use variable
1K₂MnF₆ + aSbF₅⇒ bKSbF₆ + cMnF₃ + dF₂
K, left=2,right=b⇒b=2
Mn, left=1, right=c⇒c=1
Sb, left=a, right=b⇒a=b=2
F, left=6.1+5a, right=6b+3c+2d
equation:
6+5(2) = 6(2)+3(1)+2d
16=15+2d
1=2d
d=0.5
So the reaction equation becomes:
1K₂MnF₆ + 2SbF₅⇒ 2KSbF₆ + 1MnF₃ + 0.5F₂ x2
2K₂MnF₆ + 4SbF₅⇒ 4KSbF₆ + 2MnF₃ + F₂
Answer:
True
Explanation:
The speed that electromagnetic waves will travel within any medium is the same as those without a medium. The speed of electromagnetic wave is a constant and does not depend on the material of the medium.
- Electromagnetic waves are waves that do not require a material medium for their propagation.
- They are able to pass through vacuums and mediums with particles at constant speed.
- It is mechanical waves whose speed is medium dependent.
- Mechanical waves have varying speed based on the mediums they move through.
The SI unit for the amount of substance present is the mole.
The mole is defined as the amount of substance that has the same amount of particles as there are atoms in 12 grams of carbon-12. Mathematically, the moles of a substance may be computed using:
moles present = mass of substance / molecular mass of substance
