Which hypothesis of Thomson's atomic model was later found to be not true by Niels Bohr and why?

1 answer:

7 0

Answer:

In 1911, Rutherford showed that Thomson's model was "wrong": the distribution of positive and negative particles was not uniform. Rutherford showed that the atom contains a small, massive, positively charged nucleus. He also agreed with Nagaoka that the electrons move in circular orbits outside the nucleus

a metal worker uses a cutting torch that operates by reacting acetylene gas, C2H2(g), with oxygen gas, O2(g), as shown in the un

harkovskaia [24]

Answer:

650 grams

Explanation:

Given that acetylene gas reacts with oxygen to produce caobon dioxide, water and heat and the unbalnced equation is

$C_2H_2(g)+O_2(g) \rightarrow CO_2(g) + H_2O(g)+ heat$

Gram-formula mass of $C_2H_2= 26$ g/mol

So, mass of 1 mole of acelylene is 26 grams

Therefore, mass of 25 moles of acelylene=25x26=650 grams

Hence, the mass of 25 moles of acelylene is 650 grams

a man with mass 60kg climbs up staircase having 30 step each of 10cm height in 10seconds.Calculate his power.

melomori [17]

Answer:

Power = Work done * time

P = (F * d) * t

P = (mg * d) * t

d = 1 step = 10 cm

30 steps = 300 cm

300 cm = 3m

P = (60*9.8 * 3) * 10

P = 17640 Watt

P = 1.764 Kilowatt
