a synthesis reaction b redox reaction c decomposition reaction d redox reaction e decomposition reaction

Explanation:

a CaO+H20=Ca(OH)2 this is a synthesis reaction because in this reaction calcium oxide reacts with water to form calcium hydroxide

b Fe +CuSO4= FeSO4+Cu this is a redox reaction as in this reaction iron is oxidized to form ferrus sulphate and copper sulphate is reduced to copper

c C10H8+12O2= 10CO2+4H2O this is a decomposition reaction because in this reaction the hydrocarbon C10H8 undergo breakdown by oxidation to form carbon dioxide and water.

d NaCl+AgNO3=NaNO3+AgCl this is a redox reaction because in this reaction NaCl is oxidized to form NaNO3 whereas AgNO3 is reduced to form AgCl.

e NH4NO3=N2O+2H2O this is a decomposition reaction as ammonium nitrate in this reaction undergo breakdown to form nitrous oxide and water.

Chemistry

What elements combined with Strontium, St, in a 1:1 ratio?

Step-by-step answer

P Answered by PhD

Answer: chalcogens.
Explanation: Strontium is an alkaline earth metal, it always exhibits a degree of oxidation in its compounds +2.
Chalcogens are a group of 6 chemical elements (oxygen O, sulfur S, selenium se, tellurium te, polonium Po) that have an oxidation state of -2 => Chalcogens will combine with strontium in a ratio of 1:1.

Computers and Technology

Write a program that reads in ten numbers from the user and displays the distinct numbers. If a number entered by the user appears multiple times, your program needs to filter the repeated numbers and therefore displaying the repeated numbers only once. For example, if the user enters the number 1, 4, 6, 1, 8, 4, 2, 1, 3,9 then the output of your program should be: 1, 4, 6, 8, 2, 3, 9.
