Chemistry
1 answer:
MissTica2 years ago
6 0

Explanation:

Intermolecular forces are electrostatic in nature and include van der Waals forces and hydrogen bonds. ... The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.May 20, 2018

What is chemistry and what types of questions do chemists try to answer
Reil [10]

Answer:

Chemistry is the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

They answer questions like,  like "What makes up this material?," "How does this material change when heated or cooled,?" What happens when I mix this material with another material,?" and "What rules determine how materials change in different situations?" What makes up Chemical X?

Calculate the mass in grams of 3. 29 x 104 mol of lithium<br><br> Help please?
Sedaia [141]

<em>Answer </em>

<em>no</em><em>. </em><em>of</em><em> </em><em>moles</em><em> </em><em>=</em>

<em>\frac{mass \: {g} \: }{ \: molecular \: wight}</em>

so, <em>mass</em><em> </em><em>(</em><em>g</em><em>)</em><em>=</em><em> </em><em>no</em><em>. </em><em>of</em><em> </em><em>mol</em><em>es</em><em> </em><em>×</em><em> </em><em>molecular </em><em>wight </em>

Explanation:

Li molecular wight equal to 6.941

mass (g)=3.29×104 <em>mol</em><em> </em><em>×</em><em>6</em><em>.</em><em>9</em><em>4</em><em>1</em><em> </em><em>=</em><em>2</em><em>3</em><em>7</em><em>4</em><em>.</em><em>9</em><em>3</em><em>g</em><em> </em><em>of</em><em> </em><em>lithium </em>

Ammonia gas can be prepared by the reaction CaO ( s ) + 2 NH 4 Cl ( s ) ⟶ 2 NH 3 ( g ) + H 2 O ( g ) + CaCl 2 ( s ) In an experi
bogdanovich [222]

The given question is incomplete. The complete question is ;

Ammonia gas can be prepared by the following reaction:

CaO(s)+2NH_4Cl(s)\rightarrow 2NH_3(g)+H_2O(g)+CaCl_2(s)

In an experiment, 27.6 g of ammonia gas, NH_3, is produced when it was predicted that 50.2 g of NH_3 would form.

What is the theoretical yield of NH_3? What is the actual yeild of NH_3? What is the percent yeild of NH_3?

Answer: a) 50.2 g

b) 27.6 g

c) 5.0 %

Explanation:

a) Theoretical yield is defined as the amount of the product that is possible in the reaction.

Theoretical yield of NH_3 = 50.2 g

b) Experimental or actual yield is defined as the amount of the product that is actually formed in the reaction.

Experimental yield of NH_3 = 27.6 g

c) Percentage yield is defined as the ratio of experimental yileld to the theoretical yield in terms of percentage.

{\text {percentage yield}}=\frac{\text {Experimental yield}}{\text {Theoretical yield}}\times 100\%

{\text {percentage yield}}=\frac{27.6g}{50.2g}\times 100\%=55.0\%

Hence percentage yield for the reaction is 55.0 %.
