What is the energy of a microwave photon that has a frequency of 9.86 x 1012 Hz?
Answers
Answer:
6.533 × 10^-21J
Explanation:
The energy of the microwave photon can be calculated using:
E = hf
Where;
E = energy of photon (J)
h = Planck's constant (6.626 × 10^-34 J/s)
f = frequency (9.86 x 10^12 Hz)
Hence, E = hf
E = 6.626 × 10^-34 × 9.86 x 10^12
E = 65.33 × 10^(-34 + 12)
E = 65.33 × 10^(-22)
E = 6.533 × 10^-21J
The energy of the microwave photon is
6.533 × 10^-21J
Which accurately labels the lysosome?
W
X
Y
Z
Answers
Answer:
The correct answer is X.
Explanation:
Lysosomes are heterogeneous structures present in animal cells which are bound by single membranes. They are of varying shape and size and contains hydrolytic enzymes inside it.
Lysosomal membrane has H⁺ ATPase which pumps H⁺ into the membrane through ATP hydrolysis. This pumping of H⁺ makes the internal pH of lysosome acidic.
Lysosome contains many hydrolytic enzymes like protease, lipase, nuclease, therefore, lysosome protects the cell from pathogens by engulfing it and hydrolyze it by its hydrolytic enzymes.
The process by which substance comes from outside cell and broken down through lysosome is called heterophagy.

If 1.5 moles of ethanol (C2H5OH) react, how many moles of water will be formed?
2 C2H5OH + 7 O2 --> 4 CO2 + 6 H2O
Answers
Answer:
4.5 moles of H2O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
C2H5OH + 3O2 —> 2CO2 + 3H2O
From the balanced equation above,
1 moles of C2H5OH reacted to produce 3 moles of H2O.
Finally, we shall determine the number of mole of H2O produced by the reaction of 1.5 moles of C2H5OH. This can be obtained as follow:
From the balanced equation above,
1 moles of C2H5OH reacted to produce 3 moles of H2O.
Therefore, 1.5 moles of C2H5OH will react to produce = 1.5 × 3/ 1 = 4.5 moles of H2O.
Thus, 4.5 moles of H2O will be produced.

How many kilojoules of heat energy are absorbed when 98.5 g of water are heated from 24.5 oC to 48.8 oC?
Answers
Answer:
10.01461 kilojoules of thermal energy are absorbed when 98.5 g of water is heated from 24.5 ° C to 48.8 ° C
Explanation:
Sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change) causing a change in temperature.
The equation that allows to calculate heat exchanges in this case is:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT is the change in temperature.
In this case:
c=4.184 [tex]\frac{J}{g*C}[/tex]m= 98.5 gΔT= Tfinal - Tinitial= 48.8°C - 24.5°C= 24.3 °CReplacing:
Q= 4.184 [tex]\frac{J}{g*C}[/tex] *98.5 g* 24.3 °C
Solving:
Q=10,014.61 J
Since 1 J is equal to 0.001 kJ, then you can apply the following rule of three: if 1 J is equal to 0.001 kJ, then 10,014.61 J is equal to how many kJ?
[tex]kJ=\frac{10,014.71 J*0.001 kJ}{1 J}[/tex]
kJ=10.01461 kJ
10.01461 kilojoules of thermal energy are absorbed when 98.5 g of water is heated from 24.5 ° C to 48.8 ° C

Answers
Answer:
Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star. This unusual orientation might be due to a collision with a planet-size body, or several small bodies, soon after it was formed.

a
which rock layers are the oldest
b
the relative age of layers of rocks and the fossils in them
c
the exact or absolute age of rock layers
d
a and b are correct
Answers
Answer:
d . a and b are correct
Explanation:
The law of superposition allows us to determine the age of rock layers and also that of the fossils within them.
The law of superposition states that "in an undeformed sequence of strata, the oldest rock layer is at the bottom and the youngest is on top".
Using this law, geochronologists can determine the relative ages of rock layers. The youngest layer will be found on top. The oldest at the bottom of the sequence. The arrangement of the layers and the fossils there in can also tell us about the ages of the fossils themselves.How many mL of methanol would

The density of 25.0 g of silver is 10.5 g/cm^3. What's the density of 95.5 g of silver?
Answers
Answer:
10.5g/cm³
Explanation:
Since the density of the silver is 10.5g/cm³, any pure sample of silver will have the same value as the density of silver.
Density is the mass per unit volume of a substance.
It is an intrinsic property of matter and does not depend on the amount of matter it contains. Every unique sample of an element or substance will have the same density no matter how big or small they are. So, despite an increase in mass for the given substance, the density will still be the same.PLZ HELP

Did the chemical reaction absorb or release energy? How do you know?
Answers
Answer:
Explanation:
All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions release energy. The law of conservation of energy states that matter cannot be created or destroyed.
The chemical reaction absorbs energy by comparing the energy received when bonds in the reactants are broken with the energy released when bonds in the products are formed. Exothermic is refers to chemical reactions that release the energy.
What is chemical reaction ?The term chemical reaction is defined as a process that leads to the chemical transformation of one set of chemical substances to another.
If heat is absorbed during the reaction,then the change in enthalpy is positive and if heat is released, then the change in enthalpy is negative.
All chemical reactions contain energy. But, not all chemical reactions release energy. In some chemical reactions, the energy is absorbed rather than released.
Thus, The chemical reaction absorbs energy by comparing the energy received when bonds in the reactants are broken with the energy released when bonds in the products are formed.
