Answer:
The sodium atom becomes a positive ion and the chlorine atom becomes neg.
Explanation:
Think about this answer
Answer:
Work done by the system = 4545 J
Explanation:
The expression for the calculation of work done is shown below as:
Where, P is the pressure
is the change in volume
From the question,
= 45 - 15 L = 30 L
P = 1.5 atm
Also, 1 atmL = 101 J
So,
(negative sign implies work is done by the system)
<u>Work done by the system = 4545 J</u>
Answer: 0.03798 kilograms
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
1 mole of chlorine gas 
weighs = 71 g
Thus 0.535 moles of chlorine gas will weigh = 
(1kg=1000g)
Thus there are 0.03798 kilograms in 12 L of chlorine gas.
Answer:
It leads to new jobs that search for innovative ways to control emissions.
Explanation:
Publishing a report that is a revised list of green house gases by scientists underscores the importance of new new jobs that seek ways of controlling emissions. The publication will inspire scientific research into control of emission of greenhouse gases. This will create new jobs for scientists who will be charged with the responsibility of ensuring that emission of Tue newly discovered greenhouse gasses is greatly reduced.
Several scientists earn a living by actively carrying out research on control of the emission of greenhouse gasses.
Answer:
262.821 g/mol is the molar mass of Beryllium diiodide.
