The complete conversion of the given examples are as follows:
a. 10.5g = 0.00105 kg
b. 1.57 km = 1570 m
c. 3.54 ug = 3.54 × 10⁻⁵ g
d. 3.5 mol = 3.5 × 10⁶ umol
e. 1.2 L = 1200 mL
f. 358 cm = 3.58 × 10⁻⁴ m³
g. 548.6 ml = 548.6 cm
Conversion is a multi-stage procedure, which requires a numerical factor to multiply or divide and the appropriate selection of a number of important digits.
Using the International System Units for Conversions Factors.
(a)
If 1 g = 0.001 kg
∴
10.5 g will be:
[tex]\mathsf{= \dfrac{10.5 \ g \times 0.0001 \ kg}{1 \ g}}[/tex]
= 0.00105 kg
(b)
If 1 km = 1000 m
1.57 km will be:
[tex]\mathsf{= \dfrac{1.57 \ km \times 1000\ m}{1 \ km} }[/tex]
= 1570 m
(c)
If 1 ug = 1 × 10⁻⁵ g
∴
3.54 ug will be:
[tex]\mathsf{= \dfrac{3.54 \mu g \times 1 \times 10^{-5} \ g }{1 \ \mu g}}[/tex]
= 3.54 × 10⁻⁵ g
(d)
If 1 mol = 10⁶ umol
∴
3.5 mol will be:
[tex]\mathsf{= \dfrac{3.5 \ mol \times 10^6 \ u \ mol}{1 \ mol} }[/tex]
= 3.5 × 10⁶ umol
(e)
If 1 L = 1000 mL
∴
1.2 L will be:
[tex]\mathsf{=\dfrac{1.2 \ L \times 1000 \ mL}{1 \ L}}}[/tex]
= 1200 mL
(f)
If 1 cm = 0.000001 m³
∴
358 cm will be:
[tex]\mathsf{= \dfrac{358\ cm \times 0.000001 m^3}{1 \ cm}}[/tex]
= 3.58 × 10⁻⁴ m³
(g)
If 1 mL = 1 cm
∴
548.6 mL will also be equivalent to 548.6 cm
Therefore, from the above explanation, we've seen how to convert from one unit to another.

What NaClNaCl concentration results when 259 mL259 mL of a 0.850 M0.850 M NaClNaCl solution is mixed with 567 mL567 mL of a 0.240 M0.240 M NaClNaCl solution?
Answer:
0.431M
Explanation:
To find the concentration of NaCl we need to know how many moles comes from each solution. Then, we need to sum the total volume in liters and, as molarity (Unit of concentration) is the ratio between moles and volume we can determine concentration.
Moles from first solution:
259mL = 0.259L * (0.850mol / L) = 0.22015 moles of NaCl
Moles from second solution:
567mL = 0.567L * (0.240mol / L) = 0.13608 moles of NaCl
Total moles:
0.22015 + 0.13608 = 0.35623 moles of NaCl
Total volume:
259mL + 567mL = 826mL = 0.826L
Thus, molarity of the mixture is:
0.3562 moles NaCl / 0.826
0.431M

How can nuclear energy be converted in electrical energy
Answer:
A clean energy resource
Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.

How were the ideas of Aristotle and Democritus similar to the alchemists'?
Answer:
The ideas of Aristotle and Democritus were on a similar basis to the alchemists.
Explanation:
Aristotle believed that all matter was made from four elements: earth, air, fire, and water. Democritus was the first person to realize that if something was cut in half continuously it can never be broken down completely. Democritus called the units that could not be broken down atoms. Early alchemists believed and based their works on the notion that atoms could be rearranged into making new elements. All three of their ideas more or less work with atoms and elements.

Which of the following properties of an unknown substance would allow it to be classified as a mixture? The unknown substance
Answer:
D. has different properties when sampled in different areas.
Explanation:
The general property of a mixture says that each substance or component in a mixture has its individual or different property which can be separated on the basis of different methods.
Such as a mixture of oil and water is a heterogeneous mixture and have different properties or different densities, which helps them to be sampled in different areas.
Hence, the correct answer is "D".

Your answer should indicate the proper precision (correct number of insignificant figures).
1. 1,010 L
2. 1,007.0 L
3. 1,007 L
4. 1,000 L
Answer:
The sum of given measurements is 1007 L.
Explanation:
The given measurements are 28 L, 42 L, 6 L, and 931 L.
We need to find the total of these measurements.
Total = 28 L + 42 L + 6 L + 931 L
It can be written as
Total = ( 28 +42+6+931)
One simplification we get Total = 1007 L
The healing of a cut finger. Is it a physical or chemical change? Explain.
Wound healing is a chemical change.
A chemical change involves the formation of a new substance. A substance changes form from one form into another in the process. A physical change does not involve the formation of new substances. Wound healing involves a number of chemical changes.
A wound can also be referred to as a tissue damage. When a tissue is damaged, bleeding results. Bleeding could lead to so much loss of blood.
The human body has mechanisms in place to combat this excessive loss of blood. This occurs when a complex biochemical pathway leads to the formation of fibrinogen. The enzyme thrombin converts fibrinogen to fibrin. The formation of fibrin is very essential to the wound healing process.
We can see that a series of chemical changes are involved in the process of wound healing when your finger is cut.

why scientists use the word dominant
Answer:
Dominant traits are traits that more likely to be transferred from a parent to an offspring so scientist use this term dominant.
Answer:
Scientists use the word dominant for certain traits because they are more likely to show up. There are two different types of alleles for traits: dominant and recessive. Capital letters mean dominant and lowercase mean recessive. Scientists also use the word dominant for certain traits when certain traits stand out and are more prone to show up in offspring.
