Answer:
[tex]\boxed {\boxed {\sf 600 \ kg/m^3}}[/tex]
Explanation:
We are asked to find the density of a bowling ball. The density of an object is its mass per unit volume. It is calculated by dividing the mass by the volume.
[tex]\rho= \frac{m}{v}[/tex]
The mass of the bowling ball is 3.0 kilograms and the volume is 0.0050 cubic meters.
m= 3.0 kg v= 0.0050 m³Substitute the values into the formula.
[tex]\rho= \frac{3.0 \ kg}{0.0050 \ m^3}[/tex]
Divide.
[tex]\rho= 600 \ kg/m^3[/tex]
The density of the bowling ball is 600 kilograms per cubic meter.

Explain why silver iodide, Agl, a compound used in
photography, has a much higher melting point than
vanillin, C,H,O3, a sweet-smelling compound used
in flavorings.
Answer:
Vanillin consists of molecules. The attraction between particles of silver iodide is stronger than the attraction between particles of vanillin.
The silver iodide a compound used in photography because,
It affected by light.It is easily stick on the surface of photographic plate or film.Why melting point of silver iodide has higher melting point than vanillin?The ionic compound is strong than covalent compound .So, ionic compound require more energy as compare to covalent compound to break their bond between them. So, melting point of ionic compound is higher than covalent compound .Since, silver iodide is ionic compound and vanillin covalent compound.Therefore, melting point of silver iodide is higher than vanillin.learn about melting point,

Apply the fertilizer.
Answer:
AbstractOrganic fertilizers are an essential source for plant nutrients and a soil conditioner in agriculture. Due to its sources and the composition of the organic inputs as well as the type, functionality and failures of the applied treatment process, the organic fertilizer may contain various amounts of infectious agents and toxic chemicals, especially the antibiotics that can be introduced to the subsequent food chain. A range of human and animal pathogens of bacterial, viral and parasitic origin have been the cause of food-borne epidemics due to unintended contamination from organic fertilizers. The use of antibiotics by humans and in animal feeds will also end up in the organic fertilizers. These antibiotics and other chemicals, depending on the sources of the organics, will enhance the likelihood of occurrence of resistant and multi-resistant strains of microorganisms in society and have been reported to cause ecotoxicological environmental effects and disruption of the ecological balance. Exposure of microorganisms to sublethal concentration of antibiotics in the organic products induces antibiotic resistance. WHO guidelines for the reuse of excreta and other organic matters identify the risk for the exposed groups to the reuse of the

how many moles of oxygen are in 20 grams of oxygen
Answer:
0.625
Explanation:
If you are referring the O2, first you need to get the relative mass of it. You can see the O's is around 16. but this is O2,you need to multiple it.
16×2=32
We get the equation n=m/M where m is for gram
20/32=0.625mol

658 mL of 0.250 M HCl solution is mixed with 325 mL of 0.600 M HCl solution. What is the molarity of the resulting solution
The molarity of the resulting solution obtained by mixing 658 mL of 0.250 M HCl solution with 325 mL of 0.600 M HCl solution is 0.366 M
We'll begin by calculating the number of mole of HCl in each solution. This can be obtained as follow:
For solution 1:Volume = 658 mL = 658 / 1000 = 0.658 L
Molarity = 0.250 M
Mole of HCl =?Mole = Molarity x Volume
Mole of HCl = 0.250 × 0.658
Mole of HCl = 0.1645 moleFor solution 2:Volume = 325 mL = 325 / 1000 = 0.325 L
Molarity = 0.6 M
Mole of HCl =?Mole = Molarity x Volume
Mole of HCl = 0.6 × 0.325
Mole of HCl = 0.195 moleNext, we shall determine the total mole of HCl in the final solution. This can be obtained as follow:Mole of HCl in solution 1 = 0.1645 mole
Mole of HCl in solution 2 = 0.195 mole
Total mole = 0.1645 + 0.195
Total mole = 0.3595 moleNext, we shall determine the total volume of the final solution.Volume of solution 1 = 0.658 L
Volume of solution 2 = 0.325 L
Total Volume = 0.658 + 0.325
Total Volume = 0.983 LFinally, we shall determine the molarity of the resulting solution.Total mole = 0.3595 mole
Total Volume = 0.983 L
Molarity =?Molarity = mole / Volume
Molarity = 0.3595 / 0.983
Molarity = 0.366 MTherefore, the molarity of the resulting solution is 0.366 M

it tells me that one element is more reactive than the other
Explanation:
using the reactivity series. the element that come above is the most reactive e.g

magnesium....
potassium is more reactive than sodium and the following below
calcium is more reactive than magnesium since it is below it in the reactivity series.
CONCLUSION, reactivity decreases down the reactivity series and increases up the reactivity series. the example i gave is part of the reactivity series of cations but there is also for anions

Look at the three kinds of houses shown in the simulation. Which house do you think will best resist damage from a tsunami? Which house will suffer the most damage from a tsunami? Do you think any of the houses will survive a large tsunami? Write down your predictions.
Answer:
The brick house will best resist damage from a tsunami, and the straw house will suffer the most damage from a tsunami. I predict these reasons because brick has a stronger material than the rest of the houses, while the straw house has the weakest material than the rest of the houses. No, I do not think any of the houses can survive a massive tsunami because if the tsunami was 22 feet tall, the brick house would become damaged due to the lack of support. And, the other houses can't take a tsunami higher than 10 feet. The brick house can only take tsunamis less than 20 feet.

How did the industrial revolution contribute to global climate change
Answer:humans have put ridiculous amounts of carbon dioxide into the atmosphereThese events are linked to the mass burning of fossil fuels to meet an increase in human demand
So the answer is True
Explanation:
Burning fossil fuels, such as coal and oil, has increased the quantity of greenhouse gases in our atmosphere since the Industrial Revolution began around 1750.
What is atmosphere?Atmosphere is defined as a layer of gas that surrounds a planet and is kept there by the gravitational pull of the planetary body. The atmosphere of Earth includes five primary layers and a number of minor ones.
Industrial revolution is defined as the transition of an economy based on agriculture and handicrafts to one driven by industry and machine production. The causes of industrial revolution are the advent of capitalism, European imperialism, efforts to mine coal, and the effects of the Agricultural Revolution are some of the factors that historians have recognized as contributing to the Industrial Revolution.
Thus, burning fossil fuels, such as coal and oil, has increased the quantity of greenhouse gases in our atmosphere since the Industrial Revolution began around 1750.
