Suppose that you measure a pen to be 10.5 cm long. Convert this to meters.

Answers

Answer 1
Answer: If the pen is 10.5cm long, it is 0.105 meters. This can be worked out by considering that there are 100cm's in 1 meter, so you need to divide 10.5 by 100. You then move the decimal place 2 places to the right (because of the two zeros), which leads you to your answer of 0.105.
Answer 2
Answer:

A pen measuring 10.5 cm long is equivalent to 0.105 meters.

Further Explanation

Length  

  • Length refers to a measurement of distance. It is the distance between two points.

S.I units  

  • The S.I. units of lengths. However, length can be measured using other units such as millimeters, centimeters, kilometers, etc.

Metric system unit of measurement  

  • It is a system of measurement that uses units such as gram, liter, and meter to measure mass, capacity and length respectively.
  • This system measures length based on meters, such that all the other units of lengths are based on an inter-conversion of units in meters.

Conversion of units measuring length

1 centimeter = 10 millimeters  

1 meter = 100 centimeters  

1 meter = 1000 millimeters  

1 kilometer = 1000 meters  

1 kilometer = 1000000 centimeters, and so forth.

Conversion of larger units to small units  

  • To convert larger units of measurement to smaller units we multiply we multiply the number of larger units by the appropriate conversion factor.

Conversion of smaller units to larger units

  • When converting smaller units of measurements to larger units of measurements we divide the number of smaller units by the appropriate factor.
  • For example, to convert cm to m, we divide the number of cm by 100.

In the question;

The pen measures 10.5 cm  

But, 1 meter = 100 centimeters

Thus;

10.5 cm will be equivalent to;

= 10.5 cm/100 cm  

= 0.105 meters

Therefore, a pen measuring 10.5 cm in length is equivalent to 0.105 meters.

Explain a polar molecules and give examples​

Answers

Ethanol is polar because the oxygen atoms attract electrons because of their higher electronegativity than other atoms in the molecule. Thus the -OH group in ethanol has a slight negative charge. Ammonia (NH3) is polar. Sulfur dioxide (SO2) is polar.

Determine the mass of oxygen in a 5.8 g sample of sodium bicarbonate (NaHCO3).

Answers

Answer is: the mass of oxygen is 3.31 grams.

m(NaHCO₃) = 5.8; mass of sodium bicarbonate.

n(NaHCO₃) = m(NaHCO₃) ÷ M(NaHCO₃).

n(NaHCO₃) = 5.8 g ÷ 84 g/mol.

n(NaHCO₃) = 0.07 mol; amount of sodium bicarbonate.

In one molecule of sodium bicarbonate there are three oxygen atoms:

n(NaHCO₃) : n(O) = 1 : 3.

n(O) = 3 · 0.07 mol.

n(O) = 0.21 mol.

m(O) = 0.21 mol · 16 g/mol.

m(O) = 3.31 g.

What are 5 examples of gases found at home?

Answers

Examples of gases that can be found at home include carbon monoxide, chlorine, ammonia, hydrogen, nitrogen, and sulfur oxides.

  • Gas is one of the three states of matter that we've. A gas simply means a substance that doesn't have a fixed shape and fixed volume.

  • It should also be noted that gases have lower density when compared to solid or liquid. There are different gases such as oxygen, nitrogen, helium, carbon monoxide, etc.

  • Examples of gases found at home include carbon monoxide, chlorine, ammonia, hydrogen, nitrogen, and sulfur oxides.

In conclusion, carbon monoxide is gotten when we burn wood, charcoal, fuel, etc.
