Loss of a beta particle

1 answer:

3 0

When a beta particle is emitted from the nucleus the nucleus has one more proton and one less neutron. This means the atomic mass number remains unchanged and the atomic number increases by 1.
We can also say that beta decay is a type of radioactive decay in which a proton is transformed into a neutron inside an atomic nucleus.

a) converts a neutron into a proton

Do the gas laws apply to liquids ?

Contact [7]

Answer:

The Ideal Gas Law cannot be applied to liquids. The Ideal Gas Law is #PV = nRT#. That implies that #V# is a variable. But we know that a liquid has a constant volume, so the Ideal Gas Law cannot apply to a liquid.

density of a piece of ebony wood is 1.174 g/ml. what is the volume in quarts of a 2.1549 lb piece of this ebony wood?

lapo4ka [179]

0.88qt

Explanation:

Given parameters:

Density of ebony wood = 1.174g/ml

Mass of wood = 2.1549lb

Unknown:

Volume of the wood in quarts = ?

Solution:

Density is defined as the mass per unit volume of a substance.

Mass is the quantity of matter the wood contains.

Volume is the space it occupies.

To solve this problem, convert the mass form pounds into grams and plug into the density equation to find volume.

Then convert the volume from mL to quarts.

Density = $\frac{mass}{volume}$

Volume = $\frac{mass}{density}$

1 pound = 453.592g

2.1549 lb = 2.1549 x 453.592 = 977.5g

Volume = $\frac{977.5}{1.174}$ = 832.6mL

1 quart = 946.353mL

Therefore 832.6mL x $\frac{1qt}{946.353}$ = 0.88qt

Tom [10]

Molar mass of vitamin B1, C12H17N4OS = 265.34 g/ mol

Molar mass of vitamin B2, C17H20N4O6 = 376.37 g/ mol

Molar mass of vitamin B5, C9H17NO5 = 219.24 g/ mol

Molar mass of vitamin B6, C8H11NO3 = 169.18 g/ mol

Molar mass of vitamin B7, C10H16N2O3S = 244.31 g/ mol

Now,

Order of increasing molar mass = B6 < B5 < B7 < B1 < B2

soldier1979 [14.2K]

Answer:

$Atoms_H=12Atoms$

Explanation:

Hello,

In this case, the only source of hydrogen is in the 6 molecules of water, therefore, the atoms of hydrogen, by applying stoichiometry with the Avogadro's number is:

$Atoms_H=6moleculesH_2O*\frac{1molH_2O}{6.022x10^{23}moleculesH_2O}\frac{2molH}{1molH_2O}*\frac{6.022x10^{23}AtomsH}{1molH} \\Atoms_H=12Atoms$

Best regards.
