Answer:

mental model is an explanation of someone's thought process about how something works in the real world. It is a representation of the surrounding world, the relationships between its various parts and a person's intuitive perception about his or her own acts and their consequences. Mental models can help shape behaviour and set an approach to solving problems (similar to a personal algorithm) and doing tasks.

Answer:

with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives known.

Explanation:

NTG reduces preload via venous dilation, and achieves modest afterload reduction via arterial dilation. These effects result in decreased myocardial oxygen demand. In addition, NTG induces coronary vasodilation, thereby increasing oxygen delivery.

The decomposition of nitroglycerin can result in so much more volume than the decomposition of sodium azide nitroglycerin contains a lot of nitrogen (18.5%) and has enough oxygen atoms.

A measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, like the cubic metre or litre, or different imperial or US-standard units, including the gallon, quart and cubic inch. Volume and length (cubed) have a symbiotic relationship.

The total volume much a container is usually thought of as its capacity, not as the amount of space it takes up. In other words, the volume is the quantity of fluid (liquid or gas) that the container may hold. The decomposition of nitroglycerin can result in so much more volume than the decomposition of sodium azide nitroglycerin contains a lot of nitrogen (18.5%) and has enough oxygen atoms for the nitrogen to be liberated while also oxidising the hydrogen and carbon atoms.

Therefore, the decomposition of nitroglycerin can result in so much more volume than the decomposition of sodium azide nitroglycerin contains a lot of nitrogen (18.5%) and has enough oxygen atoms.

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.

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

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.

Answer:

0,1276 M

Explanation:

Molair mass of NaOCl = 74,44 g/mol

You have 9,5 g/L.

You need to calculate with the molair mass, how many moles 9,5 g are:

9,5 g / 74,44 g/mol = 0,1276 mol

0,1276 mol / 1 L = 0,1276 M

The molarity of a bleach solution containing 9.5 g of NaOCL per liter of bleach is mathematically given as

M= 0.1276 M

Generally, the equation for the  Molar mass  is mathematically given as

M=m/(g/mol)

Therefore

M=9,5 g / 74,44 g/mol

M= 0,1276 mol

Hence

M= 0.1276 M

In conclusion, the molarity

M= 0.1276 M

Explanation: I just took the test and got it right.

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.

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.

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.

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.
