What is the conclusive evidence that mixing sugar in the water is a physical change
djyliett [7]
THE DEFINITION OF PHYSICAL CHANGE: Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds. so the answer is that the form of the sugar is changing in water but if you boiled the water till its all evaporated all that will be left is the sugar

The freezing temperatures for water for Celsius and Fahrenheit scales are 0ºC and 32ºF. The boiling temperatures for water are 1
ddd [48]

Answer:

Therefore the required function is

C= \frac{5}{9} (F-32)

Therefore 25°C=57°F

Explanation:

F denotes temperature of Fahrenheit and C denotes temperature of Celsius.

\frac{C-0}{100-0} =\frac{F-32}{212-32}

\Rightarrow C= \frac{100}{180} (F-32)

\Rightarrow C= \frac{5}{9} (F-32)

Therefore the required function is

C= \frac{5}{9} (F-32)

Putting C=25°C in above equation

25=\frac{5}{9} (F-32)

\Rightarrow 25 \times \frac{9}{5} = F-32

⇒45 =F-32

⇒F=32+45

⇒F=57

Therefore 25°C=57°F

Which sample of HCl reacts at the fastest rate with a 1.0 - gram sample of iron filling
allsm [11]

Question:

The options are;

a. 10. mL of 1 M HCl(aq) at 10.oC

b. 10. mL of 1 M HCl(aq) at 25oC

c. 10. mL of 3 M HCl(aq) at 10.oC

d. 10. mL of 3 M HCl(aq) at 25oC

Answer:

The correct option is;

d. 10 mL of 3 M HCl(aq) at 25 °C

Explanation:

Factors that influence the rate of the reaction include;

Concentration and

Temperature

Concentration

An increase in concentration leads to a increased number of interaction among the the reacting components of HCl and iron filings such that the number of effective interaction or the rate of the reaction increases, therefore, a 10 mL 3 M HCl will react faster than a 10 mL  of 1 M HCl.

Temperature

When the temperature of the reacting HCl is increased, the energy within the reacting system increases leading to an increase in the number of high energy collisions which results in an increased reaction rate, therefore, HCl at 25 °C will react faster than HCl at 10 °C.

Hence the correct option is 10 mL of 3 M HCl(aq) at 25 °C.
