Answer:
mNaCl = mNa + mCl
mNa = 20g
mCl = mCl2/2 = 30/2 = 15g
mNaCl= 20+15 = 35g
Answer: It’s called a alpha particle

Answer:
Explanation:
Data:
p₁ = 1 bar; V₁ = 5 L; T₁ = 0 °C
p₂ = 1 bar; V₂ = ?; T₂ = 45 °C
The pressure and the number of moles are constant, so, to calculate the volume, we can use Charles' Law.
Calculations:
(a) Convert temperatures to kelvins
T₁ = (0 + 273.15) K = 273.15 K
T₂ = (45 + 273.15) K = 318.15 K
(b) Calculate the new volume
Answer:
c. 0.033T - 2.6 °C
Explanation:
Hello,
In this case, we should conclude that the energy lost by the water is gained by the ice to get melted, thus, we can write them in terms of melting and cooling enthalpies:
First term includes melting enthalpy of ice that is 333.89 J/g and the second one specific heat of water that is 4.18 J/g°C, therefore, we obtain:
Thus, answer should be c. 0.033T - 2.6 °C since it includes the temperature decrease of water due to the undergoing cooling.
Best regards.
c is the answer a benzene
