Β decay can happens in two ways as β⁻ decay and β⁺ decay.
β⁻ decay is a conversion of neutron into a
proton by emission of an electron.
If β⁻ decay happens, then the daughter nucleus will have same number of mass. But the number of protons will be increased by 1 and number of neutrons will be decreased by 1 compared to parent nucleus.
β⁺<span> decay is a conversion of proton into a neutron by emitting a
positron.</span>
If β⁺ decay happens, then the daughter nucleus will have same number of mass. But the number of protons will be decreased by 1 and number of neutrons will be increased by 1 compared to parent nucleus.
Antifreeze is an additive in water-based liquid to lower down the freezing point of such liquid. It is used to make use of the colligative properties of solutions specifically freezing-point depression for cold climate and boiling-point elevation to allow higher coolant temperature.
Answer:
The answer to your question is 17.26 g of NaNO₃
Explanation:
Data
mass of NaNO₃ = ?
volume = 625 ml
concentration = 0.325 M
Process
1.- Convert volume to liters
1000 ml ----------------- 1 L
625 ml ---------------- x
x = 625 / 1000
x = 0.625 L
2.- Find the moles of NaNO₃
Molarity = moles / volume
solve for moles
moles = Molarity x volume
substitution
moles = 0.325 x 0.625
simplification
moles = 0.203
3.- Convert moles to grams
molar mass of NaNO₃ = 23 + 14 + (16 x 3)
= 85 g
85 g ------------------ 1 mol
x ------------------ 0.203
x = (0.203 x 85) / 1
x = 17.26 g
5.78 x 10^-9
all you need to do is count the decimal places

Explanation:
A lymphocyte is a type of white blood cell that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins.
