Answer:
b
Explanation:
This means that it takes more energy or heat to increase water's temperature than it does for most other substances. The specific heat of water is greater than that of dry soil, therefore water both absorbs and releases heat more slowly than land.

When is the Northern Hemisphere tilted toward the Sun?
Answer: Summer Solstice
In North America, around June 21, Earth tilts on its axis toward the Sun. This is called the summer solstice, and it is when the Northern Hemisphere has the most daylight of any time of the year. It is also when the Sun appears to be the highest in the sky, and it has its greatest angle to Earth.
The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth's orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it's at the closest distance from the equator.

A student rings a brass bell with a frequency of 300 Hz. The sound wave
travels through brass, air, and glass. What is the wavelength of the wave in
brass?
Medium
Wave speed
(m/s)
Brass
4,700
Air
346
Glass
5,640
A. 0.64 m
B. 1.6 m
C. 0.064 m
D. 16 m
The wavelength of the wave in brass medium, given that the wave has a frequency of 300 Hz is 16 m (Option D)
How do I determine the wavelength in brass?The wavelength of a wave is defined according to the following formula:
Velocity (v) = wavelength (λ) × frequency (f)
Divide both sides by frequency
Wavelength (λ = Velocity (v) / frequency (f)
With the above formula, we can obtain the wavelength of the wave in the brass medium. Details below:
Frequency (f) = 300 HzWave speed in brass (v) of = 4700 m/sWavelength in brass (λ) = ?Wavelength (λ = Velocity (v) / frequency (f)
Wavelength in brass = 4700 m/s / 300 Hz
Wavelength in brass= 16 m
Thus, we can conclude that the wavelength is 16 m (Option D)

What is the sequence of coefficients that will balance the following decomposition reaction of dihydrogen monosulfide? H₂S ----> H₂ + S₈
8 S
In this case you must start balancing the sulfur to have 8 on each side of the reaction. So:
Answer:
Explanation:
The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.
Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.
The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.
By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.
Then, taking into account all of the above, you can determine the amount of elements on each side of the equation:
Left side: 2 H and 1 S
Right side: 2 H and 8 S
In this case you must start balancing the sulfur to have 8 on each side of the reaction. So:
8 H₂S → H₂ + S₈
Now the amount of elements on each side of the equation:
Left side: 16 H and 8
Right side: 2 H and 8 S
Now you need to start balancing the hydrogen to get the same amount from each side of the reaction. So:
8 H₂S → 8 H₂ + S₈
Now the amount of elements on each side of the equation:
Left side: 16 H and 8
Right side: 16 H and 8 S
The balanced reaction is:
8 H₂S → 8 H₂ + S₈
Scientists often need a catalyst to start a chemical reaction. They need to apply heat, acids, or other materials to jump-start the experiment.
Which phrase is the best definition of catalyst?
A. something hot
b. something acidic
c. something that triggers
d.something that is scientific
Answer:
something that triggers
Explanation:
a catalyst helps move a reaction along
A catalyst shows some specificity in its action. It speeds up only a spontaneous reaction. The best definition of catalyst is something that triggers. The correct option is C.
What is a catalyst?A substance which increases the rate of a chemical reaction without itself undergoing any permanent change chemically or quantitatively is defined as the catalyst and the phenomenon is called catalysis.
It is believed that a catalyst actually participates in the chemical reaction that is speeds up. It forms temporary bonds with the reactants yielding an intermediate activated complex.
A typical example of catalyst is iron (Fe) which is used in the Haber process for the manufacture of ammonia. The catalyst is recovered unchanged in amount and chemical composition at the end of the reaction.
In most cases, a small amount of a catalyst can speed up reaction between large amounts of reactants. A catalyst shows maximum efficiency at optimum temperature.
Thus the correct option is C.

How is heat transferred through space
Heat is transferred by energy waves moving through space. Explanation: According to research: Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible
Please give brainiest if possible, I kinda need it. Thnx!
Answer:
the transfer of energy through space is called radiation. through radiation there is no direct contact between heat source and object. sunlight radiation warms the earth's surface; radiation can also come from fires.

What is the purpose of the periodic table?
Answer:
the periodic table is important because it is organized to provide a alot of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered.
Explanation:
Two layers of earth have convection currents
Answer: Mantle and core are the two layers of the earth that have convection currents.
Explanation:
The mantle and outer core are the two layers that are associated with the convection currents. In the mantle the convection currents occur due to the heat emerging out of the core also mantle region releases heat. If the transfer of heat or convection currents stop then the mantle will not flow and the core will not produce magnetic field at all. This will lead to coldness in earth and earth will lose the protection from harmful radiations.
