Answer:
By holding another magnet close to it. If the object is attracted to the magnet, then it too is magnetic.
Newton's second law states that F=ma so that means force =mass×acceleration force and mass
Sulphur
The missing element is sulphur
Here the compound is composed of element X and chlorine.
it is given,
XCl (6) ----> 6Cl
mass = 13.1%
it is X and Cl = 100%-13.10%
= 86.90%
chlorine = 86.90
X = 13.10
We assume 100g of sample
so according to the above solved data, in 100g of sample we have 86.90 g of chlorine.
now we split that chlorine into two moles of chlorine.
- Every mole of sale has 35.45 grams of sales. 2.451 moles of seal are mine after that.
- We are aware that cl is six times more than X. To find the moles of X, I must divide this number by six.
- we discover that we have 0.4086 moles of X when we divide this by six.
- We obtain those moles of X from 13.10 g of X.
- Given that Mueller masses grams per mole, I can compute the molar mass.
- 13.10 grams of X are contained in 0.4086 moles of X.
- Or, to put it another way, each remote has a molar mass of 32–06 grams.
- The element with this molar mass is sulfur, as I can see from the periodic table.
- Okay, so the element we're looking for in this situation is sulfur.

When light travels from a medium with higher refractive index to a medium with lower refractive index, the critical angle is the angle of incidence above which light is reflected only (no refraction occurs), and the value of this critical angle is given by

where n2 is the refractive index of the second medium and n1 is the refractive index of the first medium.
In this problem, the first medium is the glass (

), while the second medium is oil (

), therefore the critical angle is given by
