Boyle found that when the pressure of gas at a constant temperature is increased, the volume of the gas decreases. when the pressure of gas is decreased, the volume increases. this relationship between pressure and volume is called Boyle's law.
1 is the number of unpaired electrons in the outer subshell of a Cl atom
Answer:
D. 0.160
Explanation:
The solution A is obtained adding 2.0mL of a solution of bromocresol green, 5.0mL of 1.60M HAc and 2.0mL of a solution of KCl. The solution is diluted to 50mL
That means the HAc is diluted from 5.0mL to 50.0mL, that is:
50.0mL / 5.0mL = 10 times.
And the final concentration of HAc must be:
1.60M / 10 times =
0.160M
Right answer is:
<h3>D. 0.160</h3>
The answer is A - cytosine and adenine
Answer:
Q = 693 J
Explanation:
NaCl (aq) + AgNO₃ (aq) → AgCl (s) + NaNO₃ (aq)
Q = mcΔT
Q: heat
m: mass
c: specific heat
ΔT: temperature variation
Q = (50.0g + 100.0g) x (4.20 J/g°C) x (25.2°C - 24.1°C)
Q = 693 J
