Babies are born at 40 weeks. If a baby is born before the due date‚ they will be classed as premature. Premature babies generally take longer to meet the early development milestones‚ Newborn babies spend more time sleeping than being awake. It is very important to a newborn baby to spend quality time bonding with their primary carer. Babies develop fast during the first four weeks; feeding and sleeping patterns can start to form and will start to communicate through smiling and crying. As from

Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur‚ the equation for this reaction is: Na2 S2 O3 + HCL‚ H2 O + NaCL + SO2 + S Sodium Thiosulphate + Hydrochloric

The national unemployment rate fell to 4.4 percent in October the lowest level of unemployment since May 2001. This is a sign of unexpected strength in the job market. [The unemployment rate is based on a survey of households‚ rather than the survey of employers used to calculate the payroll number. Unemployment does not include full-time students‚ the retired‚ children‚ or those not actively looking for a paying job.] The unemployment level is defined as the labor force minus the number of people

experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values of m and n. The temperature dependence of the rate constant is given by (2)
