Answer:
Thermal energy is taken from heat sink in higher temperature. A thermal power machine does mechanical energy using part of the heat.
Part of heat taken are given in cold reservoir in lower temperature
Explanation:
Answer:
Explanation:
1. Number of electrons
2. Number of protons
3. Identify the ion
An atom with 26 protons is iron, Fe.
A neutral atom of iron would have 26 electrons.
The ion has only 24 electrons, so it has lost two. The ion must have a charge of +2.
(d) Density of Benzene: 0.8786 g/cm cubed
(m) Mass: 20.00g
Formula to solve (v) volume of benzene: V=m/d
V=20g / 0.8786g/cm cubed
Answer: Volume of benzene is: 22.8 cm cubed
Explanation: Well, density is mass divided volume. In this, it is what the volume is. All you need is mass divided by density. Hope this helps!
Answer:
4.6L
Explanation:
Use the equation (P1*V1)/(T1)=(P2*V2)/(T2)
P= pressure
V= volume
T= temperature in kelvins (remember K= C + 273)
Convert atm to mmHg or vise versa
1.5atm*(760mmhg/1atm)= 1140mmHg
(733mmHg * 5.36L)/(298K)=(1140mmHg * V)/(402K)
V= 4.6 or 4.65L (depending on sig figs)
