Calculate the moles of HCl in 15 mL of a 0.50 M solution.
Verizon [17]

Explanation:

\tiny\implies Molarity =  \dfrac{no. \: of \: moles \: of \: solute \times 1000}{volume \: of \: the \: solution \: (in \: ml)}

\tiny\implies 0.50 =  \dfrac{no. \: of \: moles \: of \: solute \times 1000}{15}

\tiny\implies no. \: of \: moles \: of \: solute \times 1000  =  0.50 \times 15

\tiny\implies no. \: of \: moles \: of \: solute \times 1000  =  7.5

\tiny\implies no. \: of \: moles \: of \: solute   =   \dfrac{7.5}{1000}

\tiny\implies  \bf no. \: of \: moles \: of \: solute   =   0.075 \: mol

In a nuclear reaction, which quantity is the same before and after the change?(1 point)
swat32

Answer:

in alpha decay, shown in Fig. 3-3, the nucleus emits a 4He nucleus, an alpha particle. Alpha decay occurs most often in massive nuclei that have too large a proton to neutron ratio. An alpha particle, with its two protons and two neutrons, is a very stable configuration of particles. Alpha radiation reduces the ratio of protons to neutrons in the parent nucleus, bringing it to a more stable configuration. Many nuclei more massive than lead decay by this method.
