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 gas with an empirical formula C2H2O has a molecular weight of 120.6g/mol. A possible molecular formula for the gas is
Virty [35]

M(C2H2O)= 12.0*2 +1.0*2 +16.0 = 42 g/mol is a molar mass for empirical formula.

120.6g/mol/42g/mol ≈ 3

So, empirical formula should be increased 3 times,

and molecular formula is C6H6O3.

Answer is D.

What is a balanced equation for the neutralization of these two compounds? <br><br> HCl <br> Ca(OH)2
loris [4]

In order to balance this, you have to count each element where the elements in the reactants side and the product side should have equal number of molecules. The balanced reaction is as follows:


2HCl + Ca(OH)2 = CaCl2 + 2H2O

What is the highest sublevel for the element Boron?
Nesterboy [21]

Answer:

2p

Explanation:

Boron is a member of group 13. The highest energy sub-level is usually found on the outermost shell of the atom of the element involved.

For a group 13 element, its outermost shell configuration is ns2 np1. The electronic configuration for boron is; 1s2 2s2 2p1.

Hence the highest energy sub-level in boron is 2p.

If solid ammonium fluoride (NH4F) is dissolved in pure water, will the solution be acidic, neutral, or basic?
Leokris [45]

Answer:

Dissolving NH4F in water will form a weak acidic solution.

Explanation:

That it is a weak acid solution means that it has a pH below 7 but close to the value, that is, it does not contain as many acids as those substances that are around a pH of 1 to 4, generally weak acids have a pH approximately 5 to 6
