Urricanes<span> act as giant heat engines, so it is logical to assume that an </span>increase<span> in sea surface temperatures (SSTs) will make more intense </span>hurricanes<span>. Indeed, there is a general consensus among </span>hurricane<span> scientists that an </span>increase<span> in SSTs due to global warming, should, in theory, lead to more intense </span>hurricanes<span>.</span>As the storm gets stronger, it gets rounder and the eye begins to form. Really stronghurricanes<span> have very clear round eyes like the one in this picture. The most intense winds in a </span>hurricane are in the thunderstorms that form the eyewall. Tropical cyclones strengthen when all of the conditions are right for them.
Answer:
d is the right one. aaßriadjcjfjfjfdjfjf
Litmus paper turns red in acidic conditions whether its blue or red litmus ,its not NH3 (ammonia) , neither is it barium hydroxide (A) , sodium hydroxide (B) will make it blue or remain blue (depemding on type of paper used ) so it has to be D which is the chemjcal formula for acetic acid , hope this helps !
Answer:
26 grams of D will be produced.
Explanation:
The reaction is given by:
A + B -----> C + D
Mass of A reacted = 21 g
Mass of B reacted = 22 g
Mass of C formed = 17 g
Mass of D formed = m =?
According to law of conservation of mass, the total mass of the reactants used is equal to the total mass of the product formed.
Then:
mass of A reacted + mass of B reacted = mass of C formed + mass of D formed
21 + 22 = 17 + m
m = 26 g
Physical changes happen when you do/mix something that can be reversed. Best example is ripping a paper, you can just tape it back together so it is just an observable thing that changes, which is a physical change. Chemical changes happen when you mix things and they make a new substance and can’t be reversed. The best example of this is the Statue of Liberty, which changed in color due to the chemical change between the oxygen and copper, which created a new substance (rust) which made it green instead of copper.
Sorry for the long answer but hope this helps!
