Answer:
<em>D. Hydrochloric acid solution with a pH of 1</em>
Explanation:
Because they are different elements have different number of protons and neutrons........ I guessed do not trust me...
Answer:
The temperature is 1,532.52 °K= 1,252.37 °C
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
The equation known as the ideal gas equation explains the relationship between the four variables P (Pressure), V (Volume), T (Temperature) and n (Amount of substance) and where R is the molar constant of the gases as follows :
P * V = n * R * T
In this case:
- P= 1920 mmHg
- V= 22,400 mL= 22.4 L (Being 1 L=1,000 mL)
- n= 0.45 moles
- R= 62.36367
Replacing:
1920 mmHg* 22.4 L= 0.45 moles* 62.36367 *T
Solving:
T=1,532.52 °K= 1,252.37 °C (Being 0°C=273.15°K)
<em><u>The temperature is 1,532.52 °K= 1,252.37 °C</u></em>
X: 1S²2S²2P⁶
Y: 1S²2S²2P⁶3S²3P⁶
The statement which is most likely correct about the two elements is
They will not react because both have a complete outermost shell and are stable.
<u><em>Explanation</em></u>
The P orbital can hold a maximum of 6 electrons,therefore the 2P orbital for x and 3P orbital for Y which are outermost subshell are fully filled .
This make element Y and x stable since they cannot react either by gaining or losing electrons.
The formula to determine the wavelength is, De-Broglie wavelength formula:
-(1)
where, is wavelength, m is mass, v is velocity and h is Planck's constant = =
mass, m = 147 g (given)
Since, 1 g = 0.001 kg
So, 147 g = 0.147 kg
v = 91.0 mph (given)
Converting mph to mps:
Since,
So, =
Substituting the values in formula 1:
Hence, the wavelength wavelength of a 147-g baseball traveling at 91.0 mph is
.
