Reactants: H₂SO₄ + 2 NaOH
Products: 2 H₂O + Na₂SO₄
The answer is A.
Answer:
B. 1.82(10³) seconds (1820 seconds)
Explanation:
Speed of Light: 3.00(10⁸) m/s or 3.00(10⁵) km/s
We know the distance from the Moon to Earth as 5.46(10⁸) km
We simply divide the distance by the speed of light:

We should get 1820 seconds or B. 1.82(10³) as our answer.
Answer 0.5
when reporting calculations from sig figs, report the number of sig figs in the least accurate measurement
so
((2.0265-2.02)/2.0265) x 100.00
((2.0265/2.0265) - (2.02/2.03)) X 100.00
(1.0000 -0.995) X 100.00
0.005 X 100.00
0.5
