Answer:
True
Explanation:
Protons have a positive electrical of +1
Answer:
387 g/mol
Explanation:
The molar mass is a ratio comparing a substance's mass and molar value. The specific ratio looks like this:
Molar Mass (g/mol) = mass (g) / moles
You can plug the given values into the ratio to find the molar mass.
Molar Mass = mass / moles
Molar Mass = 0.406 g / 0.00105 mol
Molar Mass = 387 g/mol
Answer:
the answer is electrons
Explanation:
electrons are responsible for the chemical bonding.
Answer:
0.895 g/mL
Explanation:
Step 1: Given data
Mass of liquid Z (m): 2.763 lb
Volume of liquid Z (V): 5.93 cups
Step 2: Convert "m" to grams
We will use the relationship 1 lb = 453.59 g.
Step 3: Convert "V" to milliliters
We will use the relationship 1 cup = 236.59 mL.
Step 4: Calculate the density of the liquid Z
The density (ρ) of the liquid Z is equal to its mass divided by its volume.
Answer:
Explanation:
This signifies a defect in mass. The phenomenon is known as mass defect. Mass defect is compares the mass of an isotope to that of the nucleons in the nucleus.
The mass defect implies the energy that was given off when the protons and neutrons combine to form the new helium atom. The mass defect helps us to understand why the mass of an atom might not eventually correspond to what we obtain theoretically by calculation.
