Answer:

45K

Explanation:

Rise in temperature = Final - initial temperature.

temperature in K = Temperature in Celsius + 273

for Celsius; T2 -T1 =45°C

for kelvin; T2+273 -(T1+273) = ?

                T2+273 -T1-273 =?

                T2-T1 = ?

               T2-T1 =45k

hence ΔT(K) = ΔT(°C) (temperature difference in Celsius is equal to temperature difference in kelvin)

What is the molar mass of cholesterol if 0.00105 mol weigh 0.406 g?
Rudiy27

Answer:

387 g/mol

Explanation:

The molar mass is a ratio comparing a substance's mass and molar value. The specific ratio looks like this:

Molar Mass (g/mol) = mass (g) / moles

You can plug the given values into the ratio to find the molar mass.

Molar Mass = mass / moles

Molar Mass = 0.406 g / 0.00105 mol

Molar Mass = 387 g/mol

What evidence did wegener use to create his theory of continental drift?
Thepotemich [5.8K]

Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator.

The type of bond between atoms in a molecule of CO2 (electronegativity difference = ~1)
maxonik [38]
Carbon dioxide, or CO_{2}, is a pure covalent bond. 

pure - it's non-polar, because it's a linear & symmetrical bond.

covalent - covalence is when 2 electrons are shared by a pair of atoms. in the case of carbon dioxide, it's three atoms with  an oxygen atom on the right, an oxygen atom on the left, and a carbon atom smack in the middle. 2 of carbon's extra electrons are shared with the right oxygen, and 2 other extra atoms are shared with with left oxygen.
