Answer:
No, scientists did not accept Wegener's theory
Explanation:
In a book titled; "The Origin of Continents and Oceans", published in 1915, Wegener introduced his ideas about the theory of continental drift.
According to his idea, "all the continents were once joined together in an "Urkontinent" before breaking up and drifting to their current positions"(live science).
Though some of his ideas were correct, some of them were also quite wrong. Scientists rejected his idea because he did not detail any mechanism by which the continental drift occurs.

Hope this help you
Explanation:
The answer is 261.3368. We assume you are converting between grams Barium Nitrate and mole. You can view more details on each measurement unit: molecular weight of Barium Nitrate or mol The molecular formula for Barium Nitrate is Ba(NO3)2.
Answer:
the formula to calculate speed is d/t.
First we assume that the compound containing only C,H,and
O is combusted completely in the presence of excess oxygen, so that the only
things that can be produced are water and carbon dioxide.
From there we should back calculate the amount of
Hydrogen that is in the original sample by taking all of the hydrogen in the 0.239g
to came from the organic compound.
And since we know that the original mass of the sample
was .100g, we can also easily get a mass % H by taking the mass Hydrogen
calculated over the total original mass (.100 g)
So that:
0.239g H2O / (18.01 g/mol) = .01327 moles H20
.01327 Moles H20 * 2.02g H (per every mole H2O) = .0268g
H initially present in the sample
.0268g H / .100g sample = 26.8% H by mass
