It is the alpha particle

Answer: The correct answer is alpha particle.

Explanation:

There are 3 radioactive particles which are released in radioactive decay process:

1. Alpha particle: This particle is released when a nuclei undergoes alpha decay. The particle released has a mass of 4 units and has a charge of 2 units. The particle is positively charged.

_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}+_2^4\alpha

2. Beta-particle: This particle is released when a nuclei undergoes beta decay process. The particle released has a mass of 0 units and has a charge of (-1) units.

_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta

3. Gamma radiations: These radiations are released when an unstable nuclei undergoes gamma ray emission and gives excess energy by a spontaneous electromagnetic process. The radiations does not carry any charge and has no mass.

_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma

Hence, the radioactive particle that is charged charged and has two protons and two neutrons is the alpha particle.

Which label belongs in the region marked X?
lubasha [3.4K]

Answer:

A) involves changes in temperature

Explanation:

The figure is missing, but I assume that the region marked X represents the region in common between Gay-Lussac's law and Charle's Law.

Gay-Lussac's law states that:

"For an ideal gas kept at constant volume, the pressure of the gas is directly proportional to its absolute temperature"

Mathematically, it can be written as

p\propto T

where p is the pressure of the gas and T its absolute temperature.

Charle's Law states that:

"For an ideal gas kept at constant pressure, the volume of the gas is directly proportional to its absolute temperature"

Mathematically, it can be written as

V\propto T

where V is the volume of the gas and T its absolute temperature.

By looking at the two descriptions of the law, we see immediately that the property that they have in common is

A) involves changes in temperature

Since the temperature is NOT kept constant in the two laws.

In the mathematical equation showing that pressure (P) multiplied by volume (V) remains equal to a constant (k) pressure and vol
hram777 [196]

Answer:

Inversely

Explanation:

pV = k

When p increases, V must decrease for k to remain constant.

When V increases, p must decrease for k to remain constant.

When the product of two variables is a constant, they are inversely proportional  to each other.

Ten pints of 15 % salt solution are mixed with 15 pints of 10 % salt solution. What is the
sergij07 [2.7K]
Concentration\ rate=\frac{mass\ of\ product}{mass\ of\ substance}*100\%\\\\
15\%=\frac{m_1}{ms_1}*100\%\\ms_1=10pints\\
15\%=\frac{m_1}{10}*100\%\\
\frac{15}{100}=\frac{m_1}{10}\ \ |*10\\
m_1=\frac{150}{100}=1,5pints\\\\
10\%=\frac{m_2}{15}*100\%\\
0,1=\frac{m_2}{15}\ \ |*15\\
1,5=m_2\\
Resulting\ solution:\\
ms=ms_1+ms_2=15+10=25pints\\m=m_1+m_2=1,5+1,5=3pints
\\\frac{m}{ms}*100\%=\frac{3}{25}*100\%=12\%
