Tomtit [17]

Answer:

B- He is correct. Evaporation is a physical change, but dissolving salt in water is a chemical change. The change in mass is evidence that a chemical change occurred.

Explanation: Dissolving Salt in water is a Chemical Change, Because the Salt arrangement is different in solid state than dissolved in water. As we can see in the image below, once the Salt is dissolved, it is separated into its ions, Na+ and Cl- Now, The evaporation process is a physical change, because the water doesn´t change its configuration H20 and it only changes its form, as we can see in the image below.

Find the value of T1 if 1 = 30°, 2 = 60°, and the weight of the object is 139.3 newtons.

Lelechka [254]

Answer:

Option A (69.56 newtons) is the appropriate solution.

Explanation:

According to the question,

On the X-axis,

⇒ $T_1Cos30^{\circ}-T_2Cos60^{\circ}=0$

or,

$T_1Cos 30^{\circ}=T_2Cos60^{\circ}$

On substituting the values, we get

$T_1\times \frac{\sqrt{3} }{2}=T_2\times \frac{1}{2}$

$T_1\times \sqrt{3} =T_2$ ....(equation 1)

On the Y-axis,

⇒ $T_1Sin30^{\circ}+T_2Sin60^{\circ}=139.3 \ N$

$\frac{T_1}{2} +\frac{\sqrt{3} }{2} =139.2 \ N$

$T_1+\sqrt{3}T_2=139.2\times 2$

From equation 1, we get

$T_1+\sqrt{3}\times \sqrt{3}T_1 =278.4 \ N$

$T_1+3T_1=278.4 \ N$

$4T_1=278.4 \ N$

$T_1=\frac{278.4}{4}$

$=69.6 \ N$

Answer:

Carbon will act as backbone for organic molecules

Explanation:

Life is based on carbon; substances in organic chemistry where carbon is a key element is the organic chemistry analysis. The characteristics of carbon make it the cornerstone of organic molecules that make up living substances. Carbon can create really lengthy interlocking chains of C-C bonds. It helps carbon to form the foundation of carbon-containing organic compounds, the base of all established organic livelihoods.
