Answer:
9.09cm3
Explanation:
The following data were obtained from the question:
Mass of dimethyl sulfoxide = 10g
Density of dimethyl sulfoxide = 1.10gcm−3
Volume of dimethyl sulfoxide =?
The density of a substance is simply the mass substance per unit volume of the substance. It is represented mathematically as:
Density = Mass/volume.
With the above formula, we can obtain the volume of dimethyl sulfoxide as follow:
Density = Mass/volume
1.10gcm−3 = 10g/ volume
Cross multiply to express in linear form
1.10gcm−3 x Volume = 10g
Divide both side by 1.10gcm−3
Volume = 10g / 1.10gcm−3
Volume = 9.09cm3
Therefore, the volume of dimethyl sulfoxide the student should pour out is 9.09cm3
CH3NH2 can only have as many hydrogen bonds as hydrogen bonding sites in the molecule. CH3NH2 has two N−H bonds and a lone pair of electrons on the nitrogen atom. Therefore, CH3NH2 can form three hydrogen bonds with water.
Metallic bonds are found in metals like zinc.
Explanation:
A low-pressure area, or "low", is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in upper levels of the troposphere.
