Answer:
Explanation:
ΔE = Δm × c^2
where,
ΔE = change in energy released with respect to change in mass
= 1.554 × 10^3 kJ
= 1.554 × 10^6 J
Δm = change in mass
c = the speed of light.
= 3 × 10^8 m/s
Equation of the reaction:
2H2 + O2 --> 2H2O
Mass change in this process, Δm = 1.554 × 10^6/(3 × 10^8)^2
= 1.727 × 10^-11 kg
The change in mass calculated from Einstein equation is small that its effect on formation of product will be negligible. Hence, law of conservation of mass holds correct for chemical reactions.
THAT LINK IS A VIRUS NEVER GO TO A LINK and if you go to “goggle” you should see a camera icon and take a picture of the question and get the answer there
No, Alec has not.
The force due to gravity is the same on all objects, regardless of shape and size. The acceleration caused by this force is 9.81 m/s². So if there are two identical pieces of paper, both will experience an equal force of gravity.
The difference in the papers' flight paths is due to the greater air resistance that the flat paper experiences. If the same experiment were to be repeated in a vacuum chamber, both of the pieces of paper would fall at the same rate
Answer:
Straight Angle.
Explanation:
The two types of mirrors, i.e., concave mirror and convex mirror, acts in the same way when a ray is directed towards its pole, and the ray bounces back with the same intensity, and we get the exact same angle.
And, the initial angle and the reflected angle are exactly the same.
Hence, when the ray strikes the pole, in straight angle, then it forms a straight angle.
Hence, from the given option,
The correct answer is straight angle.
