Answer:
The mass percentage of bromine in the original compound is 81,12%
Explanation:
<u>Step 1: Calculate moles AgBr</u>
moles AgBr = mass AgBr / molar mass AgBr
= 0.8878 g / 187.77 g/mol
= 0.00472812 moles AgBr
⇒
Since 1 mol AgBr contains 1 mol Br-
Then the amount of moles Br- in the original sample must also have been 0.00472812 moles
<u>Step 2:</u> Calculating mass Br-
mass Br- = molar mass Br x moles Br-
= 79.904 g/mol x 0.00472812 mol
= 0.377796 g Br-
⇒
There were 0.377796 g Br- in the original sample
<u>Step 3:</u> Calculating mass percentage Br-
⇒mass percentage = actual mass Br- / total mass x 100%
% mass Br = 0.377796 g / 0.4657 g x 100 %
= 81.12%
Answer:
Plasma
Explanation:
Plasma is a substance which is extremely hot. The heat present in plasma, a gas, is provided as energy in order to split electrons and protons apart. Therefore, ions and electrons are formed as products. Plasma is a synonym to an 'ionized gas'.
Normally, the standard states, gases, liquids and solids, wouldn't produce such an outcome, as not enough energy is present to perform the splitting pattern. This can only occur for gases at extremely high temperatures.
Answer:
a seasonal prevailing wind in the region of South and Southeast Asia, blowing from the southwest between May and September and bringing rain
Explanation:
It becomes colder as the thermometer stays inside the beaker for longer. Also, the thermometer would be at the bottom of the beaker and there all of the cold water is collected as it is very dense and so it sinks whereas the hot water is less dense and rises.
