The cold cream will drop to the bottom of the cup. When it warms, some of it will rise back to the surface.

<h2><u><em>Explanation</em></u></h2><h2><u><em></em></u></h2>

<u><em>Convection is what drives the spread of the cold cream through the hot coffee. Since the cold cream is denser than the hot coffee, it will drop to the bottom of the cup. The cream's density will decrease as it warms. Once the cream at the bottom warms past a certain point, its density will be low enough that some of it will rise back to the surface.</em></u>

How many moles of H3PO4 would produce 12 moles of water in this reaction? ЗKOH + H3PO4 K3PO4 + 3H20
Olenka [21]

Answer:

4 moles of H₃PO₄

Explanation:

The reaction expression is given as;

     3KOH   + H₃PO₄   →   K₃PO₄   +  3H₂O

Number of moles of water  =  12moles

Unknown:

Number of moles of H₃PO₄ = ?

Solution:

 From the balanced reaction expression we see that;

          3 moles of water is produced from 1 mole of H₃PO₄

So;    12 moles of water would be produced from \frac{12}{3} = 4 moles of H₃PO₄

Sulfur is an element that can be seen on the periodic table. What will most likely occur if sulfur forms an ionic bond with anot
Yakvenalex [24]

What is likely  to occur  if sulfur  forms an ionic  bond with another  element  is  <u>sulfur  will accept  electrons</u>

     

    <u><em> explanation</em></u>

  • Ionic bond is formed when  a metal react with a non metal.
  • Metal  loses ( donate) electrons  to form cation ( a positively charged  ion) , while  non metal accept (gain)  electrons  to form anion ( a negatively charged ion ).

  • Sulfur  is a non metal  therefore it  accept  electrons if it form an ionic bond  with a metal. sulfur accept  2 electrons to  form S2- ion

Standard temperature and pressure (STP), in the context of gases, refers to a) 298.15 K and 1 atm b) 273.15 K and 1 atm c) 298.1
lina2011 [118]

Answer : The correct option is, (B) 273.15 K and 1 atm

Explanation :

STP : STP stands for standard temperature and pressure.

STP conditions :

The temperature is, 0^oC or 273.15K or 32^oF

The pressure is, 1atm or 101.325kPa

The volume is 22.4 L for 1 mole of a substance.

Hence, the correct option is, (B) 273.15 K and 1 atm

A solution of NaOH has a concentration of 25.00% by mass. What mass of NaOH is present in 0.250 g of this solution? Use the peri
meriva
The concentration of NaOH is 25.00% by mass, it means that 25.00% of the mass of the solution is of NaOH. Hence:

m_{NaOH}=25.00\%\times m_{solution}\Longrightarrow m_{NaOH}=\dfrac{25}{100}\times 0.250~g\iff\\\\\boxed{m_{NaOH}=0.0625~g}
