If 1520 J are added to 16.5 g of water at 63.1 c what will the final temperature be

Answer:

Explanation:

Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years.

Answer:

The volume in milliliters is 250mL

Explanation:

The volume of a rectangle is obtained using the equation:

Volume = Length * Width * Height

In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:

Volume = 5cm * 5cm * 10cm

Volume = 250cm³

1mL = 1cm³.

That means the volume in milliliters is 250mL

The energy transformation which produces electricity and is least likely to

negatively impact the environment is generating electricity from a solar

panel system.

Generating electricity from solar panel involves the use of solar energy from

the sun to generate electricity . This type of energy doesn't emit any type of

harmful radiation or release toxic compounds into the atmosphere which

makes it the least likely to negatively impact the environment.

Other options emit any type of harmful radiation or release toxic compounds

into the atmosphere which makes option D the most appropriate.

Sodium fluoride is conceived to be composed of equal numbers of

Na+ and F− ions that are electrostatically bonded together in an extended, non-molecular array. And therefore sodium fluoride is neutral.

Explanation:

Answer:

At room temperature, mercury and bromine are of fluid consistency, it is because their melting or melting temperature is very low, so low that it reaches room temperature.

Compared to mercury and other metals, the more traditional metals have much higher melting temperatures.

On the other hand, bromine is not a metal, since it does not have the ability to oxidize with the presence of oxygen and also does not give up electrons.

Explanation:

Mercury in the periodic table is Hg, and bromine is Br

Answer: double displacement

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

The balanced chemical equation is:

[tex]3ZnS+2AlP\rightarrow Zn_3P_2+Al_2S_3[/tex]

Thus as ions get exchanged , it is double displacement reaction.

It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.

These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang. Heavier atoms such as carbon, oxygen and iron, have since been continuously produced in the hearts of stars and catapulted throughout the universe in spectacular stellar explosions called supernovae.

Explanation:

Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. ... It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.

Answer:

A.

The sound is transmitted through water until it reaches the other whale.

Explanation:

When one whale makes a sound, the sound is transmitted through water until it reaches the other whale. The sound causes a ripple-like effect in the water, producing waves that travel in the water. The waves are heard in all directions. This is why humans can hear the sounds animals make underwater.

The statement which best describes how the sound gets to the other whale is that all of the sounds absorbed by water change to heat before getting to the other whale. Thus, the correct option for this question is A.

The transmission of sounds is generally carried out through a medium in the form of waves. These sound waves involve the pattern of disturbance caused by the movement of energy.

In an aquatic environment, when one whale successfully constructs a sound, the sound is effectively transmitted through the medium that is known as water.

It remains in the form of waves until it reaches the other whale. The sound in a waveform provokes a ripple-like effect in the water and travels in the water. The waves are effectively heard in all directions.

Therefore, the correct option for this question is A.

Answer:

Matter cannot be created destroyed

Explanation

Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

Answer: I think the answer is The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes.

Explanation: Because the muscles would make the food smaller and the enzymes have a chemical change to it because it changes the molecules in the food.

The chemical processes in food digestion results in the formation of new

substances.

The statement that best describes the changes in food during digestion is;

The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.

Reasons:  

The given processes in the digestion of food are;

Stomach: Food churning is the process by which the small intestine vigorously turns ingested food.

Small intestine: The action of the peptidase enzyme is to increase the rate of the digestion of food.

Therefore;

The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.
