If an object has a density of 0.55 g/mL, what is its density in cg/L?

Chemistry

expeople1 [14]3 years ago
3 0

"cg" is centigram, which is one-hundredth of a gram.

I will first convert from g to cg (multiply by 100), then from mL to L (multiply by 1000).

\frac{0.55g}{mL}*\frac{100cg}{1g}*\frac{1000mL}{1L}=55,000\frac{cg}{L} \ or \ 5.5e4\frac{cg}{L}

What is the mass of carbon dioxide formed when 36g of carbon is burnt?<br> C+O2 -------&gt;C02
Anestetic [448]

Answer:

Mass = 132 g

Explanation:

Given data:

Mass of CO₂ formed = ?

Mass of C burnt = 36 g

Solution:

Chemical equation:

C + O₂    →    CO₂

Number of moles of carbon:

Number of moles = mass/molar mass

Number of moles = 36 g/ 12 g/mol

Number of moles = 3 mol

now we will compare the moles of carbon and carbon dioxide.

                C           :        CO₂

                 1           :         1

                3           :         3

Mass of CO₂:

Mass = number of moles × molar mass

Mass = 3 mol × 44 g/mol

Mass = 132 g

During the first half of the 20th century, the theory of plate tectonics was developed. Evidence supporting this theory included
Makovka662 [10]

A) GPS monitoring and satellite imagery of crustal movements

Explanation:

The most recent evidence supporting the theory of plate tectonics is the use of  GPS monitoring and satellite imagery of crustal movements.

GPS denotes Global Positioning Systems.

Satellite imagery is a recent advancement in the study of moving plates.

  • The global positioning system uses the position of a system of satellites in space to delineate positions on earth.
  • It works on the principles of triangulation and this helps to fix positions of objects on the earth surface.
  • With this, the change in position of the plates can be recorded by known fixed positions of objects.
  • Satellite imagery helps to map changes in terrain with time.
  • Images can be correlated through time and the shift in terrains delineated.

What does it mean to say that the average daytime relative humidity of a particular city is 31 percent?
Irina-Kira [14]
This means that the air in that city has less than a third of water vapor it could contain under the same circumstances. Relative humidity is the ratio of water vapor that the air contains to the maximum amount it could carry at the same temperature. When the humidity is high the water vapor in the air is a lot and vice versa.

Why does blowing carbon dioxide gas into aqueous barium hydroxide reduce?
Oksana_A [137]
<span>If one chooses to blow carbon dioxide gas into aqueous barium hydroxide it will reduce. This happens because the ions become removed from the solution and in turn this decreases the conductivity of it.</span>

Answer:

please mark as brainliest

Explanation:

Any substance that inhibits the growth and replication of a bacterium or kills it outright can be called an antibiotic. Antibiotics are a type of antimicrobial designed to target bacterial infections within (or on) the body. This makes antibiotics subtly different from the other main kinds of antimicrobials widely used today:

Antiseptics are used to sterilise surfaces of living tissue when the risk of infection is high, such as during surgery.

Disinfectants are non-selective antimicrobials, killing a wide range of micro-organisms including bacteria. They are used on non-living surfaces, for example in hospitals.

Of course, bacteria are not the only microbes that can be harmful to us. Fungi and viruses can also be a danger to humans, and they are targeted by antifungals and antivirals, respectively. Only substances that target bacteria are called antibiotics, while the name antimicrobial is an umbrella term for anything that inhibits or kills microbial cells including antibiotics, antifungals, antivirals and chemicals such as antiseptics.

Most antibiotics used today are produced in laboratories, but they are often based on compounds scientists have found in nature. Some microbes, for example, produce substances specifically to kill other nearby bacteria in order to gain an advantage when competing for food, water or other limited resources. However, some microbes only produce antibiotics in the laboratory
