What is the density of a bowling ball with a mass of 3.0 kg and a volume of 0.0050 m 3 ?

0.002 kg/m 3
0.015 kg/m 3
500 kg/m 3
600 kg/m 3

Answer:

It is called absolute humidity.

Explanation:

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:

Volume = 658 mL = 658 / 1000 = 0.658 L

Molarity = 0.250 M

Mole = Molarity x Volume

Mole of HCl = 0.250 × 0.658

Volume = 325 mL = 325 / 1000 = 0.325 L

Molarity = 0.6 M

Mole = Molarity x Volume

Mole of HCl = 0.6 × 0.325

Mole of HCl in solution 1 = 0.1645 mole

Mole of HCl in solution 2 = 0.195 mole

Total mole = 0.1645 + 0.195

Volume of solution 1 = 0.658 L

Volume of solution 2 = 0.325 L

Total Volume = 0.658 + 0.325

Total mole = 0.3595 mole

Total Volume = 0.983 L

Molarity = mole / Volume

Molarity = 0.3595 / 0.983

Therefore, the molarity of the resulting solution is 0.366 M

Apply the fertilizer.

Answer:

Organic 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

We get the equation n=m/M where m is for gram

20/32=0.625mol

Answer:

- melting

- sublimation

Explanation:

A phase change is a, well, change between phases. Solid to liquid. Gas to solid. Etc. Gases is a phase, but not a change. Reactions is a change, but not a phase change. This leaves us with melting (solid to liquid) and sublimation (solid to gas).

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.

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.

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.
