The colloid formed by ice cream remains stable only at cold temperatures. When ice cream is warmed above freezing, its dispersed particles absorb energy and begin to move faster. When the fast-moving particles collide, they sometimes stick together.
Explanation:
most common elements that bond with oxygen is <em>Hydrogen</em><em> (</em><em>H</em><em>2</em><em>)</em><em> </em><em>to </em><em>form</em><em> </em><em>water </em>
Answer:
4
Explanation:
If there is 12 boxs that cost $48, you need to divide the 12 boxs into the $48 to see how many time 12 goes into it to see how much it is. So 48 divided by 12 is 4.
The initial concentration of the unknown acid is 0.1900 M.
Explanation:
Titration is a chemical method of analysis to know the concentration and volume of the unknown chemical or analyte.
The formula for the titration is:
Macid x Vacid = Mbase x V base
The volume must be in litres. The volume is given in ml it should be divided with 1000 to obtain values in litre.
Data given are:
volume of acid= 10 ml 0.01 L
Molarity of the acid = ?
volume of the NaOH or base = 15.4 ml or 0.0154 L (equivalence point of the base)
molarity of the base = 0.1234 M
Applying the formula and putting the values, we get
Macid x 0.01 = 0.1234 x 0.0154
Macid = 0.1900 M
The weak acid is having molarity of 0.1900 M against the strong base with molarity of 0.1234M.
Answer: A) Hard middle
Explanation: He describes the hard middle as a marketing campaign in which one doesn't get much profit per sale of product (usually inexpensive) to a not so large target audience.
