What is the value of 100 ºC on the Kelvin scale? A. 100 K B. 273 K C. 373 K D. -373 K E. -300 K
insens350 [35]

Answer:

373.15 K

Explanation:

Given data:

Temperature in degree Celsius = 100°C

Temperature in kelvin scale = ?

Solution:

To convert the degree Celsius into kelvin scale we add the given  degree Celsius  into 273.15.

100°C +273.15 =  373.15 K

A piston contains 5.00 L of gas at a pressure of 101 kPa. The piston is compressed until the gas occupies 2.00 L of space. What
galben [10]

Answer: 252.5 kPa

Explanation:

Given that:

initial volume of gas V1 = 5.00 L

initial pressure of gas P1 = 101 kPa.

new Volume V2 = 2.00 L

new pressure P2 = ?

Since, only pressure and volume are involved, apply the formula for Boyle's law

P1V1 = P2V2

101 kPa x 5.0L = P2 x 2.00L

505 = P2 x 2.00L

P2 = 505/2.00

P2 = 252.5 kPa

Thus, the new pressure of gas inside the piston is 252.5 kPa

The strength of an acid is affected by the polarity of the bond connected to the acidic hydrogen. The more highly polarized this
alexgriva [62]

Answer:

Explanation:

Oxyacids are acid containing oxygen; they are also known as acid-alcohol or acid-phenol. As said earlier, the strength of these acids increases with increases in the polarity of these compounds. So, what makes the polarity is as a result of the electronegative substituents attached to it. Halogen family possesses the highest electronegativity in the periodic table, and electronegativity decreases down the group.

The ranking of the oxyacids in order of decreasing acid strength from strongest to weakest acid is:

HClO3 > . HClO2 > HClO > HBrO

Cloud [144]

Analyzing a biomolecule X, a scientist verifies that it is made up of Carbon, Hydrogen, Oxygen and Nitrogen, in addition to releasing water when it joins with other similar molecules to form polymers. Considering these antecedents, it can be inferred that biomolecule X corresponds to: A Steroids B fatty acid C nucleotide D amino acid E monosaccharide (for people who dont speak spanish)

ok you answer is probably A

if wrong C maybe

~hope~
