I believe it's (A). It will double.
Explanation:
Charles law states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure. (Charles's law).
The pressure, volume, and temperature are the main factors of the ideal gas. At constant pressure when the temperature is doubled, then volume also gets doubled. Thus, option A is correct.
What is an ideal gas law?The ideal gas law has been known as the law that relates the pressure, volume, moles, and temperature of the gas particles. The relationship between the volume and the temperature of the gas was given by Charle's law.
According to Charle's law, the volume and the temperature have been known to have direct relation when the factor of pressure is said to be constant. If they exhibit the direct relation then doubling the temperature will double the volume of the gas.
Therefore, option A. the doubling of temperature doubles the volume is correct.

If your end product is 1.5 moles of KMnO4, how many moles of manganese oxide were used in the reaction?
The equation for the production of potassium permanganate is as follows:
2 MnO2 + 4 KOH + O2 → 2 KMnO4 + 2 KOH + H2
You must show all work
Answer:
1.5 moles of KMnO4 will be produced from 1.5 moles of MnO2
Explanation:
The balanced equation of this chemical reaction is
2 MnO2 + 4 KOH + O2 → 2 KMnO4 + 2 KOH + H2
2 moles of MnO2 produces 2 moles of KMnO4
That means 1 moles of KMnO4 will be produced from 1 moles of MnO2
Hence, 1.5 moles of KMnO4 will be produced from 1.5 moles of MnO2
The moles of manganese oxide were used in the reaction is 1.5 moles.
What is stoichiometry?Stoichiometry of any reaction tells about the relative amount of species present before and after the chemical reaction.
Given chemical reaction is:
2MnO₂ + 4KOH + O₂ → 2KMnO₄ + 2KOH + H₂
From the stoichiometry of the reaction, it is clear that same moles of manganese oxide and potassium permanganate is involved in the reaction.
2 moles of KMnO₄ = produce by 2 moles of MnO₂
1.5 moles of KMnO₄ = produce by 2/2×1.5=1.5 moles of MnO₂
Hence, required moles are 1.5 moles.

Which of the following is NOT an advantage that can only be gained by the use of digital data transmission instead of analog transmission?
A. Has less static
B. Carries more information
C. Takes up less bandwidth
D. Provides higher resolution images
Answer:
D. Provides higher resolution images
Explanation:
The advantages gained by the use of digital data transmission instead of analog transmission are;
1) Noise do not damage digital signal transmission but they impact on analog signals. Digital signals are therefore more secure than analog signals
2) The bandwidth required for digital signal transmission is much less than the bandwidth required for analog
3) Digital signal allow data transmission to very long distance
4) The rate of transmission with digital signals is higher with digital signals
5) Digital signals allow easy and cost effective methods by which they are replicated
The resolution of an image is a measure of the amount of pixels displayed per inch of the image, such that a high resolution image has more pixel per inch of the image. It is therefore a factor determined at the source of the image based on how much detail is required in an image before transmission

A gas' pressure is 850 torr at 47 degrees. At what temperature will the pressure be 655 torr?
Answer:
From Pressure Law
P1/T1 = P2/T2
Changing our temp to kelvin
T1 = 47 +273 = 320K
We're looking for T2
Making T2 the subject
T2 =P2 x T1 / P1
= 655 x 320/850
T2 = 246K

What two metals are have atoms larger than that of sodium
Answer: potassium and rubidium
Explanation:
1) The group 1 of the periodic table contain six elements namely Lithium(Li), Sodium(Na),Potassium(K),Rubidium(Rb),Cesium(Cs) and Francium(Fr). These metals are called alkali metals because they form alkalies( i.e. strong bases capable of neutralizing acids) when they react with water.
2) The heavier alkali metals (K, Rb, and Cs) react so vigorously that they invariably explode.
3) This trend, which is not consistent with the relative magnitudes of the reduction potentials of the elements, serves as another example of the complex interplay of different forces and phenomena—in this case, kinetics and thermodynamics.

Answer:

Non-metal
Explanation:
Ionic compounds are said to be formed when metals donate electrons to non metals.
The metals become positively charged while the nonmetals become negatively charged.
CaF2 is composed of Ca^2+ and F^-. Calcium is a metal of group 2 in the periodic table while F is a nonmetal of group 17 in the periodic table.
Hence CaF2 is composed of a metal and a nonmetal.

Answer:
Igneous or sedimentary rocks.
Explanation:
The presence of metamorphic rock is most likely evidence of that the rock formed from igneous or sedimentary rocks. The igneous rock converted into metamorphic rocks when the rock experience intense heat and pressure within the Earth's crust. These metamorphic rocks are crystalline and often have a “squashed” texture. So due to high temperature and pressure, the metamorphic rock is formed from igneous rock.

A sample of hydrogen gas collected by displacement of water occupied 30mL at 24 C on a day when the barometric pressure was 736t orr. What volume would the hydrogen occupy if it were dry and at STP? The vapor pressure of water at 24 C is 22.4 torr
Answer:
[tex]v_2=6,48*10^{-4}L[/tex]
Explanation:
From the question we are told that:
Volume of hydrogen [tex]V_1=30mL=>30*10^{-3}[/tex]
Temperature [tex]T_1=24C=>24+273=>297k[/tex]
Pressure of water [tex]P_1=22.4torr=>\frac{22.4}{760}=0.0295atm[/tex]
Let
STP(Standard Temperature and pressure)
[tex]T_2=273K[/tex]
[tex]P_2=1atm[/tex]
Generally the equation for ideal gas is mathematically given by
[tex]\frac{p_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]
Therefore
[tex]v_2=\frac{P_1v_1T_2}{T_1P_2}[/tex]
[tex]v_2=\frac{0.0295*30*10^{-3}*273}{297*1}[/tex]
[tex]v_2=6.48*10^{-4}L[/tex] (at STP(Standard Temperature and pressure))

An electric current is produced when ______________________ move continuously batteries magnets electric charges wires
Answer:
electric charges.
Explanation:
Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction.
An electron can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
An electric current is produced when electric charges (electrons) move continuously and it's measured in Amperes through the use of an ammeter.
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
If you want to lower water's freezing point 18 degrees C by adding NaCl, what must the molality of the salt solution be? (K(f) for water ris 1.86 degree C/m)
Answer:
4.84 m
Explanation:
To solve this problem we need Frezing point depression.
Formula is: ΔT = Kf . m . i
ΔT = 18°C
This is data. ΔT is the difference, Freezing T° of pure solute - Freezing T° of solution.
Kf = 1.86 °C/m
m = molality. Our unknown.
i = Ions dissolved in solution, also called Van't Hoff factor.
NaCl → Na⁻ + Cl⁻
Sodium chloride can produce 2 moles of ions.
We replace data: 18°C = 1.86 °C/m . m . 2
18°C / (1.86 °C/m) . 2 = m
molality = 4.84
