Answer:
2M
Explanation:
M=mol/L
1. Find moles of CoCl2
mass of substance/molar mass = 130/129.833 = 1.001 mol
3. Substitute in molarity equation
M=(1.001/0.5)
M= around 2M
I got 134.91 but if you round it you’ll get 135
Answer:
2835 J
Explanation:
Take the specific heat capacity of water as 4.2 J/ g°C.
Energy (heat) = mass x specific heat capacity x change in temperature
(E= mcΔT)
E = 27 x 4.2 x (45-20)
E = 2835 J
<span>the Brazil Current has the warmest water</span>
Pressure is directly proportional to temperature.
<span>From the ideal gas law- </span>PV= nRT
by making P the subject of the formula, P= nRT/V
<span>This implies that Pressure is directly proportional to temperature, OR, as pressure increases, temperature will increase proportionally.</span>
