Hello!
To answer your question lets first establish the different parts of the atom that can be affected.
Protons: Subatomic particle in the nucleus with a positive charge
Neutrons: Subatomic particle, around the same mass as the proton, with a neutral charge.
Electrons: Subatomic particle outside the nucleus with a negative charge
This particular question relates to isotopes in our elements. It's important to note that the most common/stable forms of an element are what correspond to the periodic table however they can differ in the total particles in the nucleus.
The reason they differ is because the number of neutrons (either added or removed from the nucelus) affect the isotope! Protons and electrons stay the same however as once those are removed they represent another element.
I hope this answers your question. If you need anymore clarification please ask!
Answer:
The equilibrium temperature of the coffee is 72.4 °C
Explanation:
Step 1: Data given
Mass of cream = 15.0 grams
Temperature of the cream = 10.0°C
Mass of the coffee = 150.0 grams
Temperature of the coffee = 78.6 °C
C = respective specific heat of the substances( same as water) = 4.184 J/g°C
Step 2: Calculate the equilibrium temperature
m(cream)*C*(T2-T1) = -m(coffee)*c*(T2-T1)
15.0 g* 4.184 J/g°C *(T2 - 10.0°C) = -150.0g *4.184 J/g°C*(T2-78.6°C)
62.76T2 - 627.6 = -627.6T2 + 49329.36
690.36T2 = 49956.96
T2 = 72.4 °C
The equilibrium temperature of the coffee is 72.4 °C
The answer is B. darker; cooler the dark spots give off less energy then the rest of the sun.
Hope this helps
Answer:
24.9mL of the stock solution are required
Explanation:
To solve this question we have to find, as first, the moles of HCl that we need to prepare the desire solution. These moles are taken from the stock solution as follows:
<em>Moles diluted solution:</em>
500.0mL = 0.5000L * (0.613mol / L) = 0.3065 moles HCl
As these moles comes from the 12.3M HCl solution, the volume that we need of the stock solution is:
<em>Volume stock solution:</em>
0.3065 moles HCl * (1L / 12.3moles) = 0.0249L 12.3M HCl =
<h3>24.9mL of the stock solution are required</h3>
Answer:
the answer to this question is producer
