Explanation:
Answer:
Yes
Explanation:
Sulfur in its pure do not have any taste and odor but many foods rich in sulfur can have a distinct odor and taste. The foods contains sulfur in very small amounts but some of the foods which are known for rich in sulfur are onion, garlic, egg, flex seeds, walnuts, meat, red bell pepper, cheese, green vegetables etc.
The foods rich in sulfur helps in fighting skin acne and fights skin infection which makes our skin brighter because of this property of sulfur it is used in skin antiseptic creme and medicines.
The intake of the excess sulfur can cause burning sensation, diarrhea, tonsils and even can cause brain damage if taken in too excess and death of the brain cells. So, the sulfur is good for health and is a remedy for our skin if taken by the natural source of food in a healthy amount.
Answer:
The correct alternative is "Option a".
Explanation:
Oxidation has become a mechanism whereby the physicochemical properties transform attributed to the formation of O₂.
- The connection involving magnesium as well as O₂ requires the oxidation of the component named magnesium.
- Even before exposed to the air, silicon is oxidized as well as generates silicon dioxide.
Other possibilities are not connected to the scenario in question. So Choice A is the best option.
The volume that will occupy at STP is calculated as follows
by use of ideal gas equation
that is PV=nRT where n is number of moles calculate number of moles
n= PV/RT
p=0.75 atm
V=6.0 L
R = 0.0821 L.atm/k.mol
T= 35 +273= 308k
n=?
n= (o.75 atm x 6.0 L)/( 0.0821 L.atm/k.mol x 308 k)= 0.178 moles
Agt STP 1 mole= 22.4 L what obout 0.178 moles
= 22.4 x0.178moles/ 1moles =3.98 L( answer C)
