Answer:

The mass number and the atomic number remain unchanged

Explanation:

Gamma rays are one of the rays in the electromagnetic spectrum. In fact, they have the shortest wavelength and the highest penetrating power in the electromagnetic spectrum. They are also an important component to discuss when learning about radioactivity.

They are one of the 3 main radiation emisssions alongside alpha and beta particles. While alpha and beta particles affect either the atomic or mass number or both, the gamma ray radiation does not affect any of this. They simply leave the nuclei unchanged. They only show that radiation has taken effect and most times are like an extra radiation term alongside alpha and better particles.

When a radioactive source emit gamma rays, they do so without a change in either their atomic mass and their mass number

I DON'T UNDERSTAND! PLEASE HELP.

Nookie1986 [14]

Answer:

A would be the lowest, then C, and B would be the highest.

Explanation:

Elements tend to become more reactive as you move down the periodic table. This happens because the atoms become progressively larger and lose their hold on the outer eletrons more easily.

What volume (mL) of a concentrated solution of sodium hydroxide (6.00 M) must be diluted to 187 mL to make a 1.53 M solution of

Len [333]

Answer:

47.68 mL

Explanation:

In this case, we have a dilution problem. So, we have to start with the dilution equation:

$C_1*V_1=C_2*V_2$

We have to remember that in a dilution procedure we go from a higher concentration to a lower one. With this in mind, We have to identify the concentration values:

$C_1~=~6.00~M$

$C_2~=~1.53~M$

The higher concentration is C1 and the lower concentration is C2. Now, we can identify the volume values:

$V_1~=~X$

$V_2~=~187~mL$

The V2 value has "mL" units, so V1 would have "mL" units also. Now, we can include all the values into the equation and solve for "V1", so:

$6.00~M*V_1=1.53~M*187~mL$

$V_1=\frac{1.53~M*187~mL}{6.00~M}=47.68~mL$

So, we have to take 47.68 mL of the 6 M and add 139.31 mL of water (187-47.68) to obtain a solution with a final concentration of 1.53 M.

I hope it helps!

A sample of cobalt has a mass of 27 g and a density of 9 g/cm^3. What would be its volume?

8_murik_8 [283]

Given ,

Mass of sample of cobalt = 27 g

density of sample of cobalt = 9g/cm^3

We know that ,

Density = mass of sample/volume of sample

From that relation ,

We can deduce the following as

Volume = mass of sample/density of sample

Hence , required volume of sample of cobalt = 27 g /9 g/cm^3 = 3 cm^3

The volume is $\fbox{3cm cube}$

what temperature does water freeze using degrees Celsius and what is the basic unit for measuring mass

Olin [163]

Freezing point is the temperature at which a substance undergoes a phase transition from liquid to solid state. Water converts from liquid state to solid ice at a temperature of $0^{0}C$ .

Mass is the amount of matter contained in a substance. The SI unit of mass is kilogram. 1 kilogram is equal to 1000 g. One kilogram is defined as the mass of one cubic decimeter of water at the freezing point of water.
