What is the chemical formula for nickel (ii) hypochlorite?
gtnhenbr [62]
The   chemical  formula  of  nickel  (ii) hypochlorite  is Ni(CIO)2. Nickel (II)   has a  charge  of  +2  while (CIO-)  which  is  a  poly  atomic ion  of  chlorine and  oxygen has  a  charge  of   -1.  After  balancing  the  charge  of    nickel with  that   of  CIO- you  get  the  chemical  formula  as  Ni(CIO)2.

A sample of argon gas at 55°C is under 845 mm Hg pressure. What will the new temperature be if the pressure is raised to 1050 mm
Maurinko [17]

Answer:

The final temperature at 1050 mmHg is 134.57 ^{\circ}C or 407.57 Kelvin.

Explanation:

Initial temperature = T = 55^{\circ}C = 328 K

Initial pressure = P = 845 mmHg

Assuming final  to be temperature to be T' Kelvin

Final Pressure = P' = 1050 mmHg  

The final temperature is obtained by following relation at constant volume

\displaystyle \frac{P}{P'}=\displaystyle \frac{T}{T'} \\ \displaystyle \frac{845 \textrm{ mmHg}}{1050 \textrm{ mmHg}} = \displaystyle \frac{328 \textrm{ K}}{T'} \\T' = 407.57 \textrm{ Kelvin}

The final temperature is 407.57 K

If maltose undergoes hydrolysis what subunits does it results to?
Levart [38]
<h3><u>Answer;</u></h3>

Two glucose molecules

<h3><u>Explanation;</u></h3>
  • Maltose is a disaccharide that is made up of two glucose molecules joined with an alpha(1-4) bond.
  • <em><u>Maltose is produced by the enzymatic hydrolysis of starch, a polysaccharide, catalyzed by the enzyme amylase. Maltose is then hydrolyzed by the enzyme maltase to produce two molecules of d-glucose.</u></em>
  • <em><u>The enzyme maltase efficiently catalyses the hydrolysis of maltose into 2 glucose molecules. </u></em>
