Answer:
The answer is
<h2>190.32 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of ethanol = 146.4 mL
Density = 1.3 g/mL
The mass is
mass = 1.3 × 146.4
We have the final answer as
<h3>190.32 g</h3>
Hope this helps you
Answer:
The protic solvents are (CH3)2CHOH, NH3, and HCONH2
The aprotic solvent are CH3NO2, CH2Cl2, and N(CH3)3
Explanation:
A protic solvent is a solvent that has a hydrogen atom bound to an oxygen (O), a nitrogen (N), or fluoride (F). Generally, any solvent that contains a labile H⁺ is called a protic solvent.
a. (CH3)2CHOH
(CH3)2CHOH is a protic solvent because one of the hydrogens is bound to oxygen (O)
b. CH3NO2
CH3NO2 is an aprotic (i.e not a protic solvent) solvent because all the hydrogens are bound to carbon.
c. CH2Cl2
CH2Cl2 is an aprotic solvent because all the hydrogens are bound to carbon.
d. NH3 is a protic solvent because all the hydrogens are bound to Nitrogen (N)
e. N(CH3)3 is an aprotic solvent because all the hydrogens are bound to carbon
f. HCONH2 is a protic solvent because two of the hydrogens are bound to Nitrogen (N)
Answer:
Explanation:
Water vapor, carbon dioxide, methane, and other trace gases in Earth's atmosphere absorb the longer wavelengths of outgoing infrared radiation from Earth's surface. These gases then emit the infrared radiation in all directions, both outward toward space and downward toward Earth
The question is incomplete, the complete question is;
The levels of organizations in multicellular organisms are shown below, but they are not in the correct order. Arrange the levels of organization in order from simplest to most complex. tissues organs whole organisms organ systems
Answer:
tissues --> organs --> organ system --> whole organisms
Explanation:
The levels of organizations in multicellular organisms refers to the increasing complexity of the components of the organism.
A tissue is an aggregation of cells hence it is the lowest level of organization here.
Organs are an aggregation of tissues, this is the next higher level of organization.
Organ systems are an aggregation of organs, this is the next higher level of organization.
Whole organisms are an aggregation of organ systems. This is the highest level of organization.
Periodic trends , arising due to the arrangement of the different elements in a periodic table. It includes electronegativity, ionization energy,electron affinity, atomic radius, metallic character and chemical reactivity.
With the help of the periodic trends,we can predict or determine an element's properties.
