Answer:
Metal oxide + acid —> salt + water
Explanation:
There are 101.325 kPa in 1 atm. You are given 16 kPa and convert it to atm. All you need to do is divide 16 kPa to 101.325 kPa and you will get 0.16 atm
Answer:
751.8kg/m3
Explanation:
Assuming water's density is 1,000 kg/m3 and acetone's density is 791kg/m3
we use the formula
where 1/p is the density of the mixture, xi is the mass fraction and pi is the individual density of the components of the mixture.
To calculate xi we consider that acetone and water are in a 50% proportion, this means xi is 0.5 for both substances, now we can substitute in the formula:
now we obtain p.
<em>p=751.8kg/m3</em>
I hope you find this information useful! good luck!
A physical property is any property that is measurable whose value describes a state of a physical system.A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom.The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties. A period is the name given to a horizontal row of the periodic table.a group is a column of elements in the periodic table of the chemical elements.
